Know the Signs
Six Warning Signs Your Foundation Needs Attention
Foundation problems rarely appear suddenly. They signal early — if you know what to look for. Here's what homeowners across the GTA call us about most.
Stair-Step Cracks in Brick
A telltale sign of differential settlement — your foundation is moving unevenly beneath the structure.
Water After Every Rain
Chronic moisture means your waterproofing has failed or was never installed to handle Toronto's freeze-thaw cycle.
Doors That Stick or Won't Close
Frame racking caused by foundation movement shifts door openings out of square. Doors are often the first thing homeowners notice.
Sloping or Bouncy Floors
When your floors aren't level, your foundation's structural integrity is in question. Settlement or void formation beneath the slab.
Bowing or Bulging Walls
Hydrostatic soil pressure is pushing your basement walls inward. This gets worse — not better — without intervention.
White Powder on Walls
Efflorescence is dissolved mineral salts left behind by water migrating through your concrete. It confirms active moisture movement.

What We Do
Our Foundation Services
From a single crack to a full structural rebuild — we handle every stage of foundation repair, waterproofing, and underpinning.

Foundation Crack Repair
Hairline or structural — we identify every crack type, seal it permanently, and prevent water infiltration. Epoxy injection, polyurethane foam, and carbon fibre strap solutions for Toronto homes.

Basement Waterproofing
Interior and exterior waterproofing systems designed for Toronto's freeze-thaw climate. French drains, weeping tile, waterproof membranes, and drainage board installed to code.

Foundation Underpinning
Bench-footing and pit underpinning to deepen basement slabs and reinforce aging footings. The most common reason Toronto homeowners call us when they want more headroom.

Bowed Basement Wall Repair
Hydrostatic pressure and soil movement cause inward bowing. We use carbon fibre straps, steel I-beams, and wall anchors to stabilize walls and halt further movement.

Basement Leak Repair
Water always finds the path of least resistance. We trace every leak to its origin — window wells, tie rods, cove joints, or wall cracks — then seal it from the inside or outside depending on severity.

Foundation Settlement Repair
Differential settlement cracks slabs, jams doors, and stresses structural frames. We stabilize with helical piers and push piers driven to bedrock — lifting foundations back toward original grade.

Crawl Space Encapsulation
Vapour barriers, rigid insulation, rim joist sealing, and crawl space dehumidifiers eliminate moisture, mold, and cold floors. Full encapsulation transforms crawl spaces into conditioned storage areas.

Sump Pump Installation & Service
Primary sump pump installation, battery backup systems, and combination units for Toronto's heavy spring thaw and storm events. We size pumps correctly — undersized units fail when you need them most.

Wet Basement Solutions
Chronic dampness, white efflorescence, musty odours, and peeling paint all signal a moisture problem. We assess the full picture — grading, downspouts, weeping tile, and wall integrity — before recommending the right fix.

Poured Concrete Foundation Repair
Form ties corrode, cold joints open, and shrinkage cracks widen in older poured walls. We use structural carbon fibre, epoxy injection, hydraulic cement, and crystalline waterproofing — matched to the specific defect.

Egress Window Installation
Ontario Building Code requires minimum egress openings in basement bedrooms. We cut new openings, build window wells, waterproof the assembly, and finish to code — turning dark basement rooms into legal living spaces.

Foundation Inspection & Assessment
Detailed visual and structural assessment of your foundation, drainage, grading, and waterproofing. We document every deficiency with photos and a written report — no upselling, just facts.
Why Choose Us
What Makes Toronto Foundation Repair Pros Different
Toronto has no shortage of contractors promising to fix your foundation. Most arrive with a price in mind before they've seen the problem. We built our process around the inspection first — because you can't write an honest quote for something you haven't properly assessed.
Our technicians distinguish cosmetic cracking from structural failure, identify the actual source of moisture infiltration, and recommend only what's needed — not a full-scope job when a targeted repair will do.

What We Bring to Every Job
- Written assessment before any work begins
- WSIB-covered, insured field crews

Common Questions
Foundation Repair FAQs
Real questions from Toronto homeowners who've called us about their foundation.
How do I know if my foundation crack is structural or cosmetic?
Width, pattern, and direction all matter. Horizontal cracks are almost always structural — they signal lateral soil pressure. Diagonal cracks often indicate differential settlement. Hairline vertical cracks in poured concrete are usually shrinkage-related and less urgent, but still worth sealing. We assess all three dimensions before recommending any repair.
How much does foundation repair cost in Toronto?
It depends heavily on the problem type and scope. Epoxy crack injection starts around $400–800 per crack. Interior waterproofing systems range from $5,000–$15,000 depending on linear footage. Underpinning can run $300–$500 per linear foot. Helical pier installation for settlement runs $1,500–$3,000 per pier. Our written assessment gives you exact numbers for your specific situation.
Do I need a permit for foundation work in Toronto?
It depends on the scope. Crack injection and waterproofing membranes typically don't require permits. Underpinning, structural wall repairs, and egress window installations do require a building permit from the City of Toronto. We handle permit applications where required.
Should I waterproof from the inside or outside?
Both approaches work — but they solve different problems. Exterior waterproofing addresses the root cause by applying a membrane to the outside face of the foundation wall and improving drainage around the footing. Interior waterproofing manages water after it gets in, using drain channels and sump systems. For severe cases, exterior is the gold standard. For finished basements where excavation isn't practical, interior systems are highly effective.
My house is 80 years old. Is foundation repair even worth it?
Almost always yes. Older Toronto homes with fieldstone or brick foundations need different solutions than poured concrete, but they're repairable. The key is correctly diagnosing whether you have structural movement, water infiltration, or both — then applying the right fix. Leaving problems in older foundations accelerates deterioration significantly.
How long does foundation work typically take?
Crack injection: a few hours. Interior waterproofing: 2–5 days depending on basement perimeter. Underpinning: 4–8 weeks for a standard Toronto basement. Exterior excavation and waterproofing: 3–7 days. We give you a project schedule before work begins so there are no surprises.
