Some cracks are cosmetic. Some are your house moving. A free assessment tells you which one you have — and a fixed written quote tells you exactly what the repair costs, with a warranty that transfers when you sell.
Book a Free AssessmentFrom a single leaking crack to full structural underpinning — diagnosed honestly, repaired once, warrantied in writing.
Injection repair of leaking and structural cracks in poured walls — fixed from the inside, warrantied for life of structure.
Excavation, membrane and weeping tile replacement for walls that leak everywhere, not just at one crack.
Push piers and underpinning for sinking foundations — and basement lowering to turn crawlspaces into living space.
Bowing block walls braced and rebuilt; stone foundations repointed and stabilized — the older-home specialties.
Guelph has three foundation generations: rubble-stone (pre-1940s homes downtown and in the Ward), concrete block (post-war through the 70s), and poured concrete since. Each fails differently — stone seeps through mortar joints, block bows under lateral soil pressure, and poured walls crack at windows and corners as they cure and settle.
Our region's clay-loam soils swell when wet and shrink hard in drought summers, which is why settlement cracks often appear after dry years. Most of what we assess turns out to be manageable — and we'll tell you when a crack is just a crack. When it isn't, you'll get the engineering-grade fix, not a smear of hydraulic cement.
We serve: Guelph, Fergus, Elora, Cambridge, Rockwood, Acton, Erin and surrounding Wellington County communities.
Width and pattern matter more than length. Hairline vertical cracks in poured concrete are usually shrinkage. Horizontal cracks in block walls, stair-step cracks in mortar joints, cracks wider than 6 mm, or any crack that's growing — those need professional eyes promptly.
Single crack injection: $400–$900. Exterior excavation and waterproofing of a section: $2,500–$8,000. Structural underpinning: $350–$500 per linear foot. The honest answer comes after measurement, which is why assessments are free.
An unrepaired problem hurts far more. Documented repairs with transferable warranties typically satisfy buyers and home inspectors — we provide the full paper trail.
Yes — repointing, parging and interior drainage solutions for Guelph's older stone foundations. They're a different craft than poured-wall repair and shouldn't be treated the same way.
In Guelph's market, adding a legal-height basement to a century home often pays for itself in living space value — but it's a major structural project with permits and engineering. We'll give you real numbers so you can decide.
