Glossary
A
Aggregate
Granular materials such as sand, gravel, or crushed stone that are mixed with cement and water to form concrete or added to mortar for strength and bulk. Aggregates typically make up 60-80% of concrete volume and significantly affect its strength, durability, and workability. Fine aggregate (sand) fills voids between coarse aggregate particles and provides workability to the mix.
Anchor Bolt
Metal fasteners embedded in masonry or concrete to secure structural elements like sill plates, ledger boards, or equipment bases. In masonry construction, anchor bolts are set in grout-filled cores of CMU walls or cast into bond beams before the grout hardens. Ontario building codes specify anchor bolt requirements for wood-frame construction connections to masonry foundations, typically requiring 1/2-inch diameter bolts at maximum 6-foot spacing. Retrofit anchors using epoxy or mechanical expansion allow attachment to existing masonry without compromising structural integrity. Proper anchor bolt installation is critical for transferring lateral loads between wood framing and masonry foundations.
Arch
A curved structural element that spans an opening and supports loads primarily through compression. Common in masonry construction for doorways, windows, and decorative features.
Ashlar
Finely dressed and squared stone blocks laid in regular courses with thin mortar joints, creating a smooth finished appearance. This stonework technique has been used since ancient times and represents the highest quality of stone masonry craftsmanship.
ASTM Standards
Specifications developed by ASTM International (formerly American Society for Testing and Materials) that define quality requirements, test methods, and performance criteria for masonry materials and construction. ASTM standards ensure consistency, quality, and safety in masonry construction through standardized testing and specification protocols.
B
Bed Joint
The horizontal mortar joint between courses of masonry units. Bed joints distribute loads and provide weather resistance.
Bond Pattern
The arrangement of bricks or stones in a wall, including running bond, Flemish bond, English bond, and stack bond. Bond patterns provide structural stability, distribute loads evenly, and create distinctive visual appearances in masonry construction.
Bowing
Curved deformation of masonry walls under load or environmental stress, creating a concave or convex profile when viewed from the side. Bowing can result from inadequate structural design, excessive loads, foundation problems, or thermal effects. The degree of bowing indicates the severity of the structural problem and urgency of repair needs.
Breathable Sealant
Vapor-permeable water repellent coatings that protect masonry from rain penetration while allowing internal moisture to escape as vapor. Unlike film-forming sealers that trap moisture inside walls (causing freeze-thaw damage and efflorescence), breathable sealants penetrate the masonry surface and line pores without blocking them. Silane and siloxane-based products are common breathable options suitable for Ontario’s climate. Application requires clean, dry masonry and temperatures above 40°F for proper curing. Breathable sealants typically last 5-10 years depending on exposure and require reapplication when water stops beading on the surface. They’re particularly important for historic brick that must release moisture absorbed from interior humidity or ground contact.
Brick
Durable clay building blocks that form the backbone of Ontario’s heritage architecture and modern construction. Canadian bricks are manufactured to withstand extreme temperature variations from -30°C to +35°C, making them ideal for our climate. Quality varies significantly – handmade heritage bricks require specialized care, while modern bricks offer consistent performance. Common problems include freeze-thaw spalling, efflorescence, and mortar deterioration. Professional assessment helps determine whether individual brick replacement or comprehensive restoration provides the best value for your specific situation and heritage requirements.
Brick Cleaning
Professional brick cleaning revitalizes your property’s appearance while removing harmful contaminants that accelerate deterioration—but incorrect methods can cause irreversible damage to Ontario’s historic masonry. Atmospheric pollution, biological growth, paint, and efflorescence create unsightly staining while trapping moisture and chemicals that break down brick and mortar. Proper cleaning requires identifying brick type, contamination source, and selecting appropriate methods from gentle water washing to chemical cleaning or specialized techniques like laser cleaning for delicate surfaces. Pressure washing, while common, often drives water deep into masonry or erodes soft brick faces, causing more harm than good. Environmental regulations restrict certain cleaning chemicals, and cold weather limits cleaning options to prevent freeze damage. Fix My Brick uses proven cleaning methods matched to your masonry’s specific needs, revealing original beauty while preserving structural integrity. Professional cleaning can increase property value by 5-10% through improved curb appeal alone.
Brick Deterioration
Brick deterioration is the gradual breakdown of masonry materials that accelerates dramatically once protective surfaces are compromised—turning minor maintenance into major reconstruction if ignored. In Ontario, deterioration results from freeze-thaw cycles, salt damage, acid rain, moisture infiltration, and biological growth combining to attack brick and mortar. Early signs include surface flaking, powdery residue, softening mortar, and small cracks that admit more water, accelerating the destruction cycle. Different brick types deteriorate differently—soft historic brick erodes gradually while hard modern brick may suddenly spall in large sections. Understanding deterioration patterns helps predict maintenance needs and catch problems before critical failure. Fix My Brick identifies deterioration causes and implements targeted solutions from cleaning and sealing to complete restoration, stopping damage progression and extending masonry life. Regular maintenance addressing early deterioration costs 80% less than emergency repairs after structural damage occurs.
Brick Hammer
A specialized masonry hammer featuring a flat striking face for setting bricks and a sharp chisel edge for cutting and shaping brick and stone. The handle length and weight are designed for precision work while minimizing fatigue. Also called a mason’s hammer, it’s essential for trimming bricks to fit specific openings and making clean cuts in masonry units.
Brick Laying
The skilled process of placing and setting bricks in mortar to build walls, following specific patterns and maintaining proper alignment, level, and plumb. Involves spreading mortar beds, setting bricks to line, checking for level and plumb, and tooling joints. Requires understanding of bond patterns, corner construction, and integration with other building elements for structural integrity.
Brick Matching
Brick matching is the art and science of finding replacement bricks that blend seamlessly with existing masonry, preserving your building’s uniform appearance and property value during repairs. This challenge is particularly complex for Ontario’s heritage buildings where original manufacturers have closed and modern bricks differ in size, color, and texture from historic units. Factors include color variation from clay composition and firing temperature, surface texture from manufacturing method, size differences between modern modular and historic brick, and weathering patterns that change appearance over time. Solutions range from salvaging bricks from hidden areas, sourcing reclaimed brick from demolition, custom manufacturing small batches, or using staining techniques to adjust color. Poor matching creates obvious patches that decrease curb appeal and property value. Fix My Brick maintains relationships with specialty suppliers and uses proven color-matching techniques ensuring repairs blend invisibly with existing masonry, preserving architectural integrity and real estate value.
Brick Recycling
Brick recycling preserves valuable resources while providing authentic materials for heritage restoration and reducing construction waste filling Ontario landfills. Quality clay bricks can be cleaned and reused indefinitely, maintaining strength and character while saving the embodied energy of manufacturing new units. Reclaimed brick from careful demolition provides matching materials for heritage repairs when new bricks can’t replicate historic appearance. The recycling process involves removing mortar, cleaning, grading by condition, and palletizing for reuse. Salvaged brick often costs less than new specialty units while providing authentic weathered appearance impossible to replicate. Environmental benefits include reduced landfill waste, lower carbon emissions than new brick production, and preservation of agricultural land from clay extraction. Fix My Brick sources reclaimed brick for restoration projects and carefully salvages useable materials during demolition. Understanding brick recycling helps property owners make sustainable choices while potentially saving money on repairs requiring matched materials.
Brick Repair
Professional restoration of damaged, cracked, or deteriorating bricks to restore structural integrity and curb appeal. Common in Ontario due to harsh winter conditions causing freeze-thaw damage, brick repair involves removing damaged units and installing perfectly matched replacements. Warning signs include spalling (flaking) bricks, cracks, or loose units that could fall and cause injury. Prompt brick repair prevents water infiltration, maintains property value, and ensures family safety. Professional matching ensures repairs blend seamlessly with existing masonry.
Brick Replacement
The process of removing damaged or deteriorated bricks and installing new matching units to restore structural integrity and appearance.
Brick Spalling
Brick spalling—when brick faces flake, chip, or blow off in chunks—signals serious moisture problems requiring immediate attention before structural damage occurs. This destructive process accelerates rapidly in Ontario’s freeze-thaw climate, where water enters porous brick, freezes, expands, and literally explodes brick faces apart. Common causes include trapped moisture from failed sealers, salt contamination from de-icing chemicals, rising damp from poor drainage, and using incompatible hard mortars with soft brick. Once spalling begins, exposed rough surfaces absorb more water, accelerating deterioration in a destructive cycle. Repair involves removing damaged brick, addressing moisture sources, and installing matching replacement units with appropriate mortar. Fix My Brick diagnoses spalling causes to prevent recurrence, implementing solutions from improved drainage to breathable sealers protecting against future damage. Ignoring spalling leads to wall instability, water infiltration, and eventual reconstruction costing ten times more than timely repairs.
Brick Veneer
Brick veneer is the modern standard for residential construction in Ontario, providing the classic appearance and weather protection of brick without the full weight and cost of solid masonry walls. This system uses a single layer of brick anchored to wood or steel framing, with an air gap for drainage and insulation—combining traditional aesthetics with modern energy efficiency. However, veneer requires proper installation and maintenance to prevent water infiltration behind the brick, which can cause hidden rot, mold, and structural damage. Critical components include weep holes for drainage, proper flashing at windows and roofs, and secure brick ties connecting veneer to framing. Common problems include loose or corroded ties, blocked weep holes, and inadequate moisture barriers leading to expensive hidden damage. Fix My Brick specializes in veneer repair and restoration, ensuring your home’s protective shell functions properly while maintaining its beautiful appearance and property value.
Building Code
Legal requirements and standards governing masonry construction in specific jurisdictions to ensure public safety, health, and welfare.

Compliance is mandatory for new construction and often required for major renovations or repairs.
Building Code Compliance
Building code compliance ensures your masonry work meets Ontario’s safety standards, protecting your family while maintaining property value and insurance coverage. The Ontario Building Code sets minimum requirements for structural integrity, fire safety, and moisture control, with additional municipal requirements in many areas. Non-compliant work risks stop-work orders, forced removal, insurance claim denial, and liability for damages or injuries. Permits are required for structural repairs, additions, and sometimes even repointing depending on scope and municipality. Code requirements change regularly—what passed inspection 20 years ago may not meet current standards for seismic resistance or energy efficiency. Fix My Brick ensures all work meets or exceeds current codes, obtaining necessary permits and coordinating required inspections. Professional contractors carry liability insurance and WSIB coverage, protecting you from injury claims and defect liability. Proper code compliance documentation proves due diligence for insurance claims and adds value during property sales.
Bulging
Outward displacement of masonry walls from their original plane, often indicating structural distress, inadequate lateral support, or failure of wall ties. Bulging can result from thermal expansion, moisture expansion, structural overloading, or deterioration of connecting elements. Requires immediate evaluation to prevent potential collapse.
Bulging Wall
Outward displacement of a masonry wall, typically caused by wall tie failure, moisture damage, or structural movement. A bulging wall indicates a serious structural issue that requires immediate professional assessment and repair to prevent collapse.
Buttress
A projecting support structure built against a wall to resist lateral forces such as wind loads or thrust from arches and vaults. Buttresses transfer these forces to the foundation, preventing wall failure. Common in Gothic architecture and used in modern construction where walls face significant lateral loads or where additional structural support is needed.
C
Cavity Drainage
Cavity drainage systems are your brick wall’s hidden defense against water damage, channeling moisture that penetrates the outer brick layer safely to the exterior before it can cause structural damage or mold growth. Modern cavity walls include an air space between brick veneer and interior walls, with weep holes at the base allowing water to escape—a critical feature for Ontario’s wet climate. When drainage systems fail due to blocked weeps, missing flashing, or mortar droppings in the cavity, water accumulates causing efflorescence, interior moisture, and accelerated deterioration. Regular inspection should check that weep holes remain clear and flashing directs water outward at windows, doors, and floor lines. Retrofitting drainage in older solid masonry walls involves installing drainage mats, through-wall flashing, and new weep systems. Fix My Brick ensures cavity drainage functions properly, clearing blockages and installing proper flashing to protect your home from hidden water damage that can cost thousands to repair.
Cavity Wall
A wall construction method with two parallel walls (wythes) separated by a continuous airspace (cavity). The cavity provides insulation and prevents moisture penetration.
Chemical Damp-Proofing
Injection treatment that creates a horizontal moisture barrier in masonry walls by filling pores with water-resistant chemicals. Used to remediate rising damp in older buildings lacking original damp-proof courses, chemical damp-proofing involves drilling holes at regular intervals along the base of walls and injecting silicone-based or resin solutions that cure to block capillary action. In Ontario, this technique addresses moisture wicking up from foundations in historic homes built before modern damp-proof membranes became standard. Effectiveness depends on proper injection depth, spacing, and allowing adequate drying time before replastering. Chemical damp-proofing is less disruptive than physical damp-proof course insertion but requires addressing the moisture source and may need complementary drainage improvements.
Chimney Cap
Protective metal or concrete covering that shields your chimney from Ontario’s harsh weather while preventing water damage, animal intrusion, and debris accumulation. Essential for preventing expensive water damage to chimney masonry, flue liner, and interior walls. A quality chimney cap prevents freeze-thaw damage to crown and brick, blocks raccoons and birds, and includes spark arrestors for fire safety. Signs you need a new cap include rust, cracks, or missing screens. Professional installation ensures proper fit, drainage, and compliance with Ontario building codes for optimal protection.

CMU (Concrete Masonry Unit)
Factory-manufactured concrete blocks used for structural and non-structural walls, foundations, and retaining walls. CMUs come in standard sizes (most common: 8x8x16 inches nominal) with hollow cores that can be reinforced with rebar and grout for structural applications. In Ontario construction, CMUs are valued for their fire resistance, durability, and thermal mass properties. Load-bearing CMU walls require proper reinforcement per building codes, while decorative split-face or ground-face CMUs provide architectural finishes without additional cladding. CMU foundations are common in residential construction where full-depth poured concrete isn’t required.
Cold Chisel
A steel cutting tool with a sharp, wedge-shaped cutting edge used for cutting and shaping stone, brick, and concrete. Unlike hot chisels used for heated metal, cold chisels are designed to cut materials at normal temperatures. Different widths and angles are available for specific applications, from precise detail work to rough shaping of masonry materials.
Column
A vertical structural element designed to support loads primarily in compression, typically circular or square in cross-section. Masonry columns can be solid stone, brick, or constructed with concrete blocks. They transfer loads from beams or slabs to foundations and may also provide architectural features in addition to structural support.
Compressive Strength
The maximum stress that masonry can withstand under compression before failure, typically measured in pounds per square inch (psi) or megapascals (MPa). Compressive strength depends on the strength of individual units, mortar, and the bond between them. This property is critical for structural design and load-bearing capacity calculations.
Concrete Block
Precast concrete masonry units (CMU) manufactured from cement, aggregate, and water, molded into hollow or solid rectangular blocks. Available in various sizes, strengths, and densities, concrete blocks are widely used for structural walls, foundations, and partition walls. They offer good thermal mass, fire resistance, and can be reinforced with steel for increased structural capacity.
Conservation
Careful preservation of historic masonry using minimal intervention approaches that respect original materials while ensuring continued structural performance. Essential for Ontario’s designated heritage properties where conservation guidelines require compatible materials and approved techniques.

Corbel
A structural piece of stone, wood, or metal jutting from a wall to carry a superimposed load. In masonry, corbels support beams, arches, or other structural elements.
Course
A horizontal layer of masonry units bonded with mortar. Courses are laid sequentially to build up masonry walls.
Crack Injection
A repair method where epoxy or polyurethane is injected into foundation cracks to seal and stabilize them. This technique fills the entire depth of the crack under pressure, creating a waterproof seal and restoring structural integrity without excavation.
Cracking
The formation of fissures or breaks in masonry materials due to various factors including settlement, thermal movement, moisture, or structural stress.
Curing
Critical process ensuring new mortar develops full strength and weather resistance by maintaining proper moisture and temperature during the first weeks after installation. Especially important in Ontario’s variable climate where rapid temperature changes can compromise mortar strength. Proper curing prevents premature cracking, weak bonds, and early failure that leads to expensive re-work. Professional contractors protect fresh mortar from freezing, excessive heat, and rapid moisture loss. Quality curing extends mortar life by decades and ensures your masonry investment provides lasting protection against Ontario’s challenging weather conditions.
D
Damp Proofing
Damp proofing protects your Ontario home from moisture damage by creating barriers that prevent water from migrating through masonry walls and foundations—essential protection in our humid climate with heavy rainfall and snow melt. Unlike waterproofing which resists water under pressure, damp proofing blocks moisture vapor and capillary action that causes interior dampness, mold growth, and material deterioration. Modern damp proof courses (DPC) use impermeable membranes, chemical injections, or specialized coatings applied at critical locations like foundation walls, below grade levels, and around windows. Signs you need damp proofing include musty basement odors, peeling paint, efflorescence on walls, or visible moisture during humid weather. Older Ontario homes often lack adequate damp proofing or have failed systems requiring retrofit solutions. Fix My Brick combines traditional and modern damp proofing techniques to create comprehensive moisture management systems that protect your investment and ensure healthy indoor air quality.
Delamination
The separation of surface layers from the body of a brick, often caused by freeze-thaw cycles or manufacturing defects. Delamination appears as flaking or peeling of the brick face and compromises both the structural integrity and appearance of the masonry.
Deterioration
Progressive breakdown of masonry materials accelerated by Ontario’s harsh climate combining freeze-thaw cycles, acid rain, salt exposure, and pollution. Early deterioration signs include minor cracking, surface scaling, or mortar softening that worsen rapidly if ignored. Advanced deterioration threatens structural safety and requires expensive reconstruction rather than affordable repairs. Professional assessment identifies deterioration causes and stages, providing targeted solutions that stop damage progression. Early intervention saves thousands in reconstruction costs while maintaining your property’s safety, value, and heritage character through proven preservation techniques.
Displacement
Movement of masonry units from their original installed position due to settlement, thermal effects, structural loads, or other forces. Displacement can be vertical, horizontal, or rotational and may indicate underlying structural problems. Monitoring displacement patterns helps identify causes and appropriate repair strategies.
Drainage System
Effective drainage systems are the unsung heroes protecting your foundation and masonry from water damage, directing thousands of gallons of annual precipitation away from vulnerable building materials. In Ontario, managing spring snowmelt, summer storms, and fall rains requires comprehensive systems including gutters, downspouts, grading, French drains, and weeping tile working together. Poor drainage causes foundation cracks, basement flooding, efflorescence, brick spalling, and landscape erosion—problems costing thousands to repair. Warning signs include pooling water near foundations, wet basement walls, eroded mortar joints, or damaged landscaping after rain. Modern solutions include permeable paving, rain gardens, and sump pump systems addressing both surface and subsurface water. Fix My Brick evaluates drainage during masonry assessments, often finding water management problems causing recurring brick and mortar damage. Proper drainage installation costs far less than repeated masonry repairs or foundation waterproofing, solving root causes rather than symptoms of water damage.
E
Efflorescence
White, chalky mineral deposits that appear on brick and stone surfaces when water carries salts through masonry and evaporates, leaving crystallized minerals behind. While efflorescence itself is mainly cosmetic, it signals ongoing moisture problems that can lead to serious structural damage if ignored. Common in Ontario’s wet spring conditions and winter freeze-thaw cycles. The white staining indicates water is penetrating your masonry, potentially causing spalling, cracking, or mortar deterioration. Professional cleaning and moisture control prevent recurring efflorescence and protect your masonry investment.

Exterior insulation transforms drafty Ontario brick homes into energy-efficient buildings while preserving interior space and architectural details—when properly integrated with moisture management systems. This approach places insulation outside the structure, keeping masonry warm and dry while eliminating thermal bridges that waste energy and cause condensation problems. Options include EIFS (synthetic stucco), mineral wool boards, or spray foam systems, each requiring careful detailing to prevent moisture entrapment that destroys brick and framing. Critical considerations include maintaining drainage planes, installing proper air barriers, and ensuring vapor permeability appropriate for existing wall assemblies. Improperly installed exterior insulation causes hidden rot, mold growth, and accelerated masonry deterioration from trapped moisture. Fix My Brick coordinates insulation upgrades with necessary masonry repairs, ensuring walls are sound before covering and drainage systems function properly. Professional installation following building science principles can reduce heating costs by 30-40% while preventing moisture problems that plague DIY attempts.
F
Fire Skin Damage
Surface deterioration of brick caused by exposure to extreme heat during a fire, characterized by spalling, discoloration, and loss of the brick’s protective outer layer. When brick is heated beyond 1000°F, the outer face can crack and separate due to differential expansion between the heated surface and cooler interior. Fire-damaged brick often appears blackened, pink-tinted (indicating structural damage), or shows a pattern of concentric cracks radiating from the heat source. Assessment requires distinguishing between cosmetic soot staining (cleanable) and structural damage requiring brick replacement. Fix My Brick evaluates fire-damaged masonry to determine which areas need cleaning versus replacement, ensuring restored structural integrity while matching original brick appearance.
Firebrick
A type of ceramic brick designed to withstand high temperatures. Used in furnaces, kilns, fireplaces, and other applications where regular masonry materials would deteriorate under extreme heat.
Flashing
Thin, impervious material installed in masonry construction to direct water away from vulnerable areas and prevent moisture penetration. Common flashing materials include copper, aluminum, lead, and flexible membranes. Properly installed flashing is critical at wall penetrations, roof intersections, window sills, and other areas where water could enter the building envelope.
Flashing Installation
The critical technique of properly placing and sealing flashing materials in masonry construction to direct water away from vulnerable areas. Requires understanding of water flow patterns, proper lapping sequences, and integration with other waterproofing systems. Poor flashing installation is a leading cause of water damage in masonry buildings.
Float
A flat, rectangular tool used to smooth and level fresh mortar, concrete, or plaster surfaces. Wood floats produce a textured finish, while plastic or metal floats create smoother surfaces. The floating process brings fine material to the surface and embeds aggregate, creating a uniform, workable surface for final finishing or further treatment.
Flue Liner
A protective clay, metal, or ceramic sleeve inside a chimney that contains combustion products and protects the masonry from heat and corrosive byproducts. Flue liners are essential for safe chimney operation and are required by building codes in most jurisdictions.
Footing
The enlarged concrete base beneath foundation walls that distributes building loads over a larger soil area to prevent excessive settlement. Footings are typically twice the width of the foundation wall and extend below the frost line. They may be stepped or reinforced depending on soil conditions and structural requirements.
Foundation
The critical structural base that supports your entire building and transfers weight safely to the ground. In Ontario, foundations must resist frost action extending 1.2 meters below grade and handle significant soil expansion-contraction cycles. Foundation problems affect everything above – including masonry walls, causing cracks, settling, and structural damage. Warning signs include cracks in foundation walls, uneven settling, or basement water infiltration. Professional foundation assessment identifies problems early, preventing expensive structural repairs and protecting your family’s safety and investment value.

Jambs must be properly constructed to maintain structural integrity while accommodating frame attachment and weathersealing requirements.
Jointer
A specialized tool used to shape and finish mortar joints between masonry units, creating consistent joint profiles while the mortar is still plastic. Different jointer shapes create various joint profiles including concave, convex, flush, and weather-struck joints. Proper jointing compacts the mortar surface and improves weather resistance of the joint.
L
Lateral Support
Structural bracing that prevents masonry walls from bowing, buckling, or collapsing under horizontal forces like wind pressure, soil pressure, or seismic loads. In masonry construction, lateral support comes from floor and roof diaphragms, intersecting walls, pilasters, or buttresses that tie walls together. Ontario’s tall masonry walls require lateral support at specific height intervals based on wall thickness and construction type. Historic brick buildings often show signs of inadequate lateral support through bulging walls or separated corners. Remediation may include installing steel tie rods, rebuilding corners with proper bonding, or adding steel plates anchored through the wall to interior framing.
Lime Mortar
Traditional mortar essential for heritage building restoration and compatible repairs on Ontario’s historic masonry structures. Unlike modern cement mortars, lime mortar remains flexible, self-heals minor cracks, and allows buildings to breathe naturally – crucial for heritage structures that predate modern waterproofing systems. Required by many heritage conservation guidelines and municipal restoration bylaws in Ontario. Using incompatible modern mortars on heritage buildings can cause expensive damage to original masonry. Professional lime mortar restoration preserves historical authenticity while providing lasting, flexible protection that moves with your building.

Quality contractors stand behind their work with strong warranties, while those offering suspiciously long coverage or no warranty often deliver substandard results requiring expensive remediation.
Moisture Infiltration
Moisture infiltration is the silent destroyer of Ontario brick homes, causing damage that often goes unnoticed until expensive repairs are needed. Water enters through deteriorated mortar joints, cracks, or damaged flashing, then freezes and expands during our harsh winters, causing progressive structural damage. Common entry points include chimney crowns, window sills, and areas where different materials meet. Early warning signs include interior wall staining, peeling paint, musty odors, or white mineral deposits (efflorescence) on brick surfaces. Left unchecked, moisture infiltration leads to spalling bricks, rotting wood framing, mold growth, and foundation problems. Fix My Brick’s comprehensive inspection identifies all moisture entry points and provides targeted solutions—from tuckpointing and waterproofing to proper drainage installation. Addressing moisture infiltration early can prevent thousands of dollars in structural repairs and protect your family’s health.
Moisture Meter Testing
Diagnostic technique using electronic meters to measure water content within masonry materials, helping identify hidden moisture problems before they cause visible damage. Pin-type meters insert probes into mortar joints to measure electrical resistance (which decreases with moisture), while non-invasive meters use radio frequency signals to scan through surfaces. In masonry assessment, moisture readings above 5% warrant investigation, while readings above 15% indicate active water infiltration requiring remediation. Fix My Brick uses moisture testing to locate water entry points, verify drying after repairs, and document conditions before and after waterproofing treatments. Testing at multiple heights reveals whether moisture is rising from below (rising damp) or penetrating from above (failed flashing or pointing).
Mortar
The crucial binding material that holds bricks and stones together while allowing natural building movement. In Ontario, mortar selection is critical due to freeze-thaw cycles requiring specific flexibility and permeability. Heritage buildings often used lime-based mortars that self-heal minor cracks, while modern construction typically uses Portland cement mortars for strength. Signs of mortar problems include cracking, crumbling, or gaps that allow water infiltration. Professional mortar analysis ensures repairs use compatible materials that won’t damage existing masonry while providing long-lasting protection.
Mortar Analysis
Mortar analysis reveals the hidden recipe that holds your masonry together, ensuring repair materials match original composition for compatible, lasting restoration that won’t damage surrounding brick. Historic Ontario buildings used lime-based mortars that remain flexible and breathable, while modern Portland cement mortars are harder and less permeable—using the wrong type causes accelerated deterioration. Laboratory analysis identifies sand gradation, binder types, and mix proportions, critical information for heritage restoration or when matching existing mortar color and texture. Incompatible mortar is harder than surrounding brick, concentrating stress and causing spalling, or too soft, eroding quickly and requiring frequent repointing. Visual and physical tests help assess mortar condition—sound mortar resists scratching while deteriorated mortar crumbles easily. Fix My Brick performs mortar analysis for historically significant projects and when standard repairs have failed, ensuring restoration mortars perform properly. Proper mortar matching extends repointing life from 5-10 years with wrong materials to 50-75 years with correct formulation.
