Concrete Repair and Resurfacing in Dundas
We repair cracked, worn and sunken concrete on Dundas homes: crack injection, slab levelling, resurfacing, step rebuilds and sealing. Most of the work is on older houses in a valley where the ground stays wet, so we check the base, the grade and where the water goes before we quote the fix. The quote is free and written, and the labour carries our lifetime warranty.

Dundas is a town of established homes, not new subdivisions. The escarpment wraps it on three sides, and much of the housing is century brick and cut stone. The concrete that goes with it, steps, walks, parging and slabs, has been through a great many freeze-thaw winters.
Most of that concrete does not need to come out. A crack can be injected, a settled slab levelled, a worn surface resurfaced and a broken step rebuilt. The full method for each is on our concrete repair and resurfacing page. This page is about what the Dundas valley and its older homes change about the job.
Wet ground and old concrete
Water runs off the escarpment on three sides and collects on the valley floor, where Spencer Creek carries it through town. Ground that catches that much runoff stays wet longer, and a century of freeze-thaw works on any concrete or masonry that stays damp.
So a Dundas repair starts with the water. We check the base, the grade and where the downspouts send their water before we quote. Caulk smeared into a moving crack opens by spring.
Steps and walks on heritage homes
In the downtown core around King and Sydenham, and on the streets climbing toward the escarpment, repairs have to sit right beside old brick and stone. We match new work to the proportions and material of what is already there, rebuilding worn steps to their original lines and keeping walks in scale with the house.
A worn surface on a sound step or walk can often be resurfaced instead of torn out. Where the damage goes all the way through, the quote says so plainly and prices the replacement.
When a crack is a water or foundation question
A crack in a walk or a garage slab is a repair job. Failed parging, or a basement wall that takes in melt every spring, is a different question, and the first move is about where the water comes from.
For those, see our basement waterproofing in Dundas and our foundation repair work. We sort out which job your house needs at the free visit.
Straight answers
Should I repair or replace the cracked concrete at my Dundas home?
It depends on the base. Repair wins when the damage is local and the base under it is still sound: one or two cracks, a slab that settled on one side, surface wear or a broken step edge. Replacement wins when the base has failed across the whole area or the surface has no sound concrete left to bond to. The written quote says which side of that line your concrete is on, and why.
Can you repair concrete on a heritage Dundas home without it looking out of place?
Yes. We match new work to the proportions and material of what is already there, rebuilding worn steps to their original lines and keeping walks in scale with the house. The aim is concrete that looks like it belongs on the street.
How much does concrete repair cost in Dundas?
There is no honest flat rate. The cost moves with the size of the area, how far the damage goes, the base and soil, access and the season. The visit and the written quote are free, and the number on the quote is the number on the invoice unless you change the job.
What does the lifetime warranty on labour cover?
Our workmanship: the site preparation and the work done as part of the job, and repairs needed because that work was done wrong. It lasts as long as you own the home where we did the work, and it is stated on every written quote. Materials carry their manufacturers' warranties.
