Foundation Repair in Dundas
We repair foundation cracks and leaks in Dundas, where the escarpment sends water down onto the valley floor and many homes stand on century stone and brick walls. A leaking crack in a poured wall usually takes polyurethane injection from inside. A wall that leaks through many joints is often a waterproofing job, and we say so. Quotes are free and in writing, and the labour carries a lifetime warranty.

Foundation work in Dundas starts with the ground. The Niagara Escarpment wraps the town on three sides, so snowmelt and rain run down the slopes onto the valley floor, and Spencer Creek carries that water through town. Soil that catches that much runoff stays wet longer, and the foundations sitting in it take the consequence.
Many of those foundations are old. Behind the 19th-century downtown, the housing runs to century brick and cut stone, some of it quarried from the escarpment itself. A wall that age does not fail the way a modern poured wall does, so the first job is to read the wall you have.
The full method, epoxy and polyurethane injection and carbon fibre, is on our foundation repair page. This page is about how those repairs fit Dundas. Send the form for a free written quote.
Wet ground and old walls: what we look at first
In Dundas, the first question is water: where it comes from, where it pools and how to move it away from the wall. A crack that leaks every spring melt may only be the place where that water found a way in. We check the grading and downspouts alongside the crack, because a repair that leaves the water in place will not last.
A thin vertical crack in a poured wall that leaks is a small, common repair. Polyurethane injection seals it from the inside face through to the soil side, and most single-crack jobs take two to four hours.
Century stone: when it is not a crack repair
An old stone wall that leaks through many joints is not a single crack, so injecting one spot rarely stops it. When we see that on a Dundas home, we tell you the job is basement waterproofing in Dundas, not crack repair, and we quote it that way.
Repairs on a heritage street also have to look right. The same goes for the parging and steps around the wall, which we match to the older house. The rest of what we do in town is on our Dundas page.
Hairline or structural: what our Dundas quote tells you
We measure width, direction, movement and offset. A crack under 1/8 in. is usually shrinkage. A crack wider than 1/4 in., one that grows each year, a horizontal crack, or one where one face sits higher than the other needs structural attention.
For a block wall with a moderate bow, under about 2 in. of deflection, carbon fibre straps epoxied to the wall stop further movement. They do not pull the wall straight, and we will not say they do. A bigger bow is a different conversation, and the quote says so. The written quote names the crack, its cause and the fix.
Straight answers
Who fixes foundation cracks and leaks in Dundas?
We do. Our union-certified crews inject leaking cracks with polyurethane, bond dry cracks with epoxy, and reinforce moderately bowing block walls with carbon fibre. Dundas books onto our Hamilton-area routes. The quote is free and in writing, and the labour carries a lifetime warranty for as long as you own the home.
My century stone foundation in Dundas leaks in several places. Can you inject it?
Usually not, and we will tell you so. Stone walls leak through joints and faces, so one injection rarely holds. The lasting answer is most often a waterproofing system. We look at how the wall is built before we quote.
Is a crack in my Dundas basement wall serious?
Most are not. Hairlines under 1/8 in. are usually shrinkage. Wider than 1/4 in., growing, horizontal or offset cracks need attention. We measure the crack, check the drainage and write down what we find.
How much does foundation repair cost in Dundas?
We do not publish a price, because the jobs are so different. The cost turns on the number of cracks, whether the fix is a seal or reinforcement, the wall height and whether drainage work is needed. The free written quote gives you the real number.
