Expansion Joint

Expansion joints are the unsung heroes of brick construction, allowing your building to move naturally with Ontario's extreme temperature changes without cracking or buckling. These intentional gaps, filled with flexible sealant, accommodate the expansion and contraction that occurs when temperatures swing from -30°C to +35°C throughout the year. Missing or failed expansion joints cause stress cracks, water infiltration, and structural damage as brick walls have nowhere to release thermal pressure. You'll find them where additions meet original structures, at regular intervals in long walls, and where different materials connect. Signs of failure include cracked or missing sealant, vegetation growth in joints, or unusual cracking patterns near joint locations. Fix My Brick inspects and repairs expansion joints as part of comprehensive masonry maintenance, using modern flexible sealants that withstand Canadian weather extremes. Proper expansion joint maintenance prevents costly structural repairs and extends your building's lifespan by decades.
