What We Do

Find the Real Source, Fix It for Good

A leak in one spot often starts somewhere else entirely. We trace it to the true entry point and repair it properly, so it doesn’t come back next storm.

Leak Source Diagnosis

Water travels before it shows. We track down where it’s actually entering — crack, joint, window well or grade — instead of just chasing the wet spot.

Crack Injection

Leaking foundation cracks are injected with polyurethane or epoxy that fills the crack full-depth and seals it tight from the inside.

Cove Joint Repair

The floor-wall cove joint is a classic leak point. We seal and, where needed, drain it so water stops tracking onto your floor.

Window Well Leaks

Leaks around basement windows and wells get sealed and re-graded so water is kept out instead of collecting and pouring in.

Exterior Fix When Needed

When a leak can’t be stopped from inside, we excavate and waterproof that section from outside to deal with it at the source.

A Repair That Holds

We don’t band-aid leaks. We fix the cause so your basement stays dry through the next big rain — backed by a written warranty.

Common Questions

Basement Leak Repair FAQ

Quick answers about basement leaks in Paris, Brantford and across SW Ontario.

Where do basement leaks usually come from?

Most often from foundation cracks, the cove joint where the floor meets the wall, window wells, or poor grading that pushes water at the house. Water can travel a long way inside the wall before it shows, which is why finding the true source matters.

Can you fix a basement leak in winter?

We assess year-round and can stop many leaks from the inside in cold weather using crack injection and sealing. Exterior excavation is best left for milder conditions, but we’ll get an active leak under control as quickly as we can.

How much does basement leak repair cost?

A single interior crack injection is far less than an exterior excavation. It depends on the source and the fix, so every quote is free and itemized in writing. Call (519) 802-2138 for a fast, no-obligation assessment.

Is the repair permanent?

We fix the cause, not just the symptom, so the repair holds. Whether it’s injection, joint sealing or an exterior fix, every repair is backed by our written warranty.

My basement only leaks in big storms — is that still worth fixing?

Yes. Occasional leaks point to a real entry point that worsens over time and through Ontario winters. Fixing it now keeps a small repair from becoming a flooded basement later.

Do you also waterproof the whole basement?

We can. If a leak is a sign of a bigger water problem, we’ll talk you through interior or exterior waterproofing so the whole basement stays dry, not just the one spot.

Dave did a great job of waterproofing our basement. Not only did he fix the problem but he also gave valuable advice. For someone like myself who knows nothing about foundation and concrete walls of homes Dave was very knowledgeable and fixed the problem with a reasonable price.

We had Dave and his crew waterproof the one side of our foundation. They were polite, efficient, reliable and very knowledgeable. I recommend On Point for all your masonry repairs.
