Foundation Crack Repair Toronto

Foundation crack repair in Toronto typically costs between $400-$800 per crack for standard-sized cracks using polyurethane or epoxy injection methods. Costs can vary based on crack size, location, accessibility, and required repair type. Structural cracks requiring reinforcement may cost $800-$1,500 per repair. During our free assessment, we'll provide an exact quote for your specific foundation issues.

Most foundation crack repairs in Toronto can be completed in a single day (4-8 hours) for standard cracks. The exact timeframe depends on the number of cracks, their complexity, and whether interior finishing must be removed for access. Injection systems typically cure within 24-48 hours, at which point the repair is fully waterproof. Our technicians can provide a specific timeline after assessing your foundation cracks.

Concerning foundation cracks typically display one or more of these characteristics: width greater than 1/8 inch, horizontal orientation, stair-step patterns in block foundations, leaking water, widening over time, or accompanying symptoms like sticking doors/windows, sloping floors, or wall bulging. While hairline vertical cracks are often normal settling, any crack allowing water infiltration should be addressed promptly. Our free assessment includes evaluation of whether cracks are structural or non-structural in nature.

Epoxy injections create a rigid, high-strength bond that restores structural integrity, making them ideal for structural cracks that need strength restoration. Polyurethane injections are flexible, expanding foam solutions that excel at waterproofing and can accommodate slight foundation movement, making them perfect for non-structural cracks with water infiltration. We often use polyurethane for actively leaking cracks and epoxy for dry structural cracks. Our technicians select the appropriate method based on your specific crack characteristics.

No, not all foundation cracks indicate serious structural issues. Many Toronto homes develop typical settling cracks, especially within the first few years after construction. Vertical hairline cracks (less than 1/8 inch wide) are usually cosmetic and result from normal concrete curing or minor settling. However, horizontal cracks, wide cracks, or those showing displacement may indicate structural concerns. Even non-structural cracks should be sealed to prevent water infiltration, which can lead to further damage over time.

Yes, most foundation cracks can be effectively repaired from the inside using specialized injection systems. Interior injection repairs are less invasive and more cost-effective than exterior excavation. Our technicians drill small ports along the crack, then inject either epoxy or polyurethane material that penetrates the full depth of the foundation wall, creating a complete seal. For actively leaking cracks or those with external factors like damaged drainage systems, we may recommend supplementary exterior repairs as well.

Properly executed foundation crack repairs using quality materials should last the lifetime of your home. Our epoxy and polyurethane injection repairs come with a 25-year transferable warranty. These modern materials bond permanently with concrete and maintain their structural integrity and flexibility as needed. However, if the underlying cause of foundation cracks (such as poor drainage, soil settlement, or hydrostatic pressure) isn't addressed, new cracks may form in different locations.

Yes, repairing foundation cracks before selling your Toronto home is highly recommended. Unrepaired foundation cracks can reduce your home's value by 10-15% or more, as buyers and home inspectors will flag them as potential red flags. The return on investment for crack repairs is excellent—typically 200-300%—meaning the repair cost is more than recovered in your selling price. Additionally, having documentation of professional repairs with a transferable warranty provides significant peace of mind to potential buyers.

Yes, we can repair foundation cracks year-round in Toronto, including during winter months. Interior injection repairs are not affected by outdoor temperatures since they're performed inside your heated basement. For exterior crack repairs, we can work in temperatures as low as -20°C using specialized cold-weather formulations of our repair materials. The only winter limitation may be for extensive exterior repairs requiring excavation when the ground is deeply frozen, though this is rare in Toronto's climate.
