Foundation Crack Repair in Toronto

We Don’t Patch Problems — We Solve Them.

When a Crack Appears, It’s Not Just Your Foundation That’s at Risk

A crack in your foundation isn’t just a line in the concrete — it’s a warning. A quiet signal from your home that something is shifting, that pressure is building, that water is waiting to make its way in.

Most people walk past that crack in the basement wall and think, “It’s nothing serious.” Until the next rainfall. Until the musty smell starts to rise. Until puddles appear on the floor. Or worse — mold, rot, and costly damage follow.

At UPR, we believe that every crack has a cause — and a solution. That’s where we come in.

Foundation Repair Is Protection — And That’s What We Do Best

We’re not a franchise. We’re not a patch-and-go operation. We’re Underground Plumbing Repair — a fully licensed and insured team with over 20 years of experience protecting homes across Toronto and the GTA.

We’ve repaired thousands of cracks:
  – Hairline fractures caused by settling
  – Stair-step cracks from freeze-thaw cycles
  – Horizontal cracks signaling structural pressure
  – Leaking foundation walls letting water seep through

And every time, we treat the repair like it’s the one holding your home together. Because sometimes, it is.

We use professional-grade materials — hydraulic cement, rubberized waterproofing solvent, membrane and full exterior excavations when needed. We don’t offer band-aids. We offer solutions that last.

We Solve It at the Root — So It Doesn’t Come Back

What sets UPR apart is simple: we don’t just fill the crack. We find out why it’s there. Drainage issues. Soil pressure. Old repairs that failed. Hydrostatic stress. We dig deeper — literally and professionally.

Our team uses diagnostics, camera inspections, and hands-on expertise to understand what’s happening behind your walls, beneath your floor, and around your foundation. Then we fix it at the source.

Because when it comes to your home’s structure, good enough isn’t good enough.
