In this comprehensive guide, we’ll explore the common masonry styles found in Guelph’s heritage homes, how to identify and address issues, and the best practices for restoring and maintaining these architectural treasures.

Common Masonry Styles in Guelph’s Heritage Homes

Guelph’s oldest homes feature a variety of masonry styles, each reflecting the era in which they were built and the materials available at the time. Here are some of the most common styles you’ll encounter:

1. Rubble Stone Masonry

Many of Guelph’s earliest homes, dating back to the mid-19th century, were constructed using rubble stone masonry. This technique involves using irregular-shaped stones of various sizes, often sourced locally, and fitting them together like a puzzle. The stones are typically held in place with lime mortar, creating a sturdy and distinctive appearance.

2. Coursed Stone Masonry

As masonry techniques evolved, coursed stone masonry became more prevalent. This method involves laying stones in horizontal rows or “courses,” creating a more uniform appearance than rubble masonry. Many of Guelph’s Victorian-era homes showcase this style, often using locally quarried limestone.

3. Brick Masonry

By the late 19th and early 20th centuries, brick became a popular building material in Guelph. Many heritage homes from this period feature intricate brickwork, including:

• Common bond: A pattern where every fifth or sixth row is turned sideways (headers) to tie the outer wall to the inner wall.
• Flemish bond: An alternating pattern of headers and stretchers (bricks laid lengthwise) in each row.
• Decorative brickwork: Including corbelling, arches, and intricate patterns using contrasting brick colors.

Identifying and Addressing Masonry Issues in Old Buildings

Heritage homes often face unique challenges when it comes to masonry. Here are some common issues to look out for and how to address them:

1. Mortar Deterioration

Over time, the mortar between stones or bricks can erode due to weathering, leading to structural instability and water infiltration. Signs of mortar deterioration include:

• Crumbling or powdery mortar
• Gaps or voids in the mortar joints
• Loose stones or bricks

To address this issue, repointing is necessary. This process involves carefully removing the deteriorated mortar and replacing it with new mortar that matches the original in composition and appearance.

2. Efflorescence

Efflorescence is a white, powdery substance that can appear on the surface of masonry. It’s caused by water-soluble salts being drawn out of the masonry as moisture evaporates. While not structurally damaging, it can be unsightly and may indicate underlying moisture issues. To address efflorescence:

1. Identify and fix the source of moisture infiltration
2. Clean the affected area with a stiff brush and water
3. For stubborn deposits, consult a professional about using specialized cleaning products

3. Spalling

Spalling occurs when the face of a brick or stone flakes off, often due to freeze-thaw cycles or the use of improper cleaning methods. To address spalling:

• Remove loose material and repoint affected areas
• In severe cases, individual stones or bricks may need to be replaced
• Address any underlying moisture issues to prevent future spalling

The house’s longevity and historical significance make it an ideal case study for examining the role of masonry in preserving our architectural heritage.

Original Masonry Techniques Used in Construction

The McFarland House’s remarkable durability can be attributed in large part to the quality of its original construction. The masons who built this home employed techniques that were both time-tested and innovative for their era.

Solid Brick Construction

Unlike many modern homes that use brick as a veneer, the McFarland House features solid brick walls. These walls, typically two or three bricks thick, provided excellent insulation and structural integrity. The bricks themselves were likely made locally, using clay from the Niagara region, and fired in nearby kilns.

Lime Mortar

The original masons used lime mortar to bind the bricks together. This type of mortar, made from limestone, sand, and water, had several advantages:

• Flexibility: Lime mortar can absorb minor structural movements without cracking
• Breathability: It allows moisture to evaporate, preventing trapped water from damaging the bricks
• Self-healing properties: Lime mortar can reform bonds after minor cracking

Flemish Bond Pattern

The bricks in the McFarland House were laid in a Flemish bond pattern, alternating headers (short ends) and stretchers (long sides) in each course. This pattern not only created an attractive appearance but also increased the wall’s structural strength.

Challenges in Maintaining Historic Masonry Structures

While the original construction of the McFarland House was robust, maintaining any historic masonry structure presents unique challenges. Over the past two centuries, the house has faced numerous threats to its integrity:
