Basement Waterproofing in Ajax, ON
Leaky or wet basement in Ajax? TCR Pro waterproofs foundations and repairs cracks with a 20-year warranty. Free inspection & quote.
South Ajax still has rows of its original wartime and postwar homes, compact houses on block foundations that have carried seventy years of Ontario winters. North of the 401, the town is much younger, with poured foundations from the 1990s onward. Both ends of town call us, for different reasons.
TCR Pro has repaired and waterproofed foundations since 1998, and Ajax’s mix of housing ages is exactly the range we work across every week.
Basement waterproofing in Ajax, old streets and new
In the older south end, block walls admit water through worn mortar joints, usually along the bottom course. The lasting fixes are exterior excavation with a membrane, or an interior drainage path that catches water at the wall base, and lot access usually decides between them.
In newer subdivisions the typical call is a leaking crack in a poured wall, or a sump system that cannot keep up during a major storm. Cracks we seal permanently with injection from inside, with no digging and minimal disruption to a finished basement.
Ajax’s creeks, including Duffins and Carruthers, mean some lots sit on ground that stays wet well after rain. Where soil moisture is constant, we make sure the repair manages water rather than merely blocking it, because blocked water finds the next weakness.
What happens after you call
We inspect the basement and the exterior, find the true entry point and check grading and downspouts while we are there. You get a written quote with the scope and a firm price, and nothing starts until you approve it.
Because this is repair, not replacement, in most cases no permits or drawings are needed. The work is scheduled around your household, kept tidy and finished with a proper cleanup.
Basement waterproofing in Ajax from TCR Pro is backed by a 20-year warranty, whether the house dates from the 1940s or the 2010s.
Many newer Ajax basements are finished as family rooms or suites, which changes how we work. We open the smallest possible section of drywall to reach the leak, keep dust contained with proper coverings and coordinate the repair so the room goes back together quickly. You should not have to gut a finished room to fix one crack.
If you are seeing damp block, a weeping crack or storm water in the basement, ask for a free estimate. Send photos by email or text if that is quicker, and we will tell you what fix we would put our name on.
Frequently asked questions
Every quote starts with an assessment of the actual damage, either from photos you send or an on-site visit. The price depends on the size of the area, the condition of the concrete, access to the site and the repair system required. You receive a written quote before any work begins, and the estimate is free.
The fastest route is to send photos of the damaged area through our contact form or by email. In many cases we can give a preliminary assessment from photos alone, and we arrange a site visit when the job needs one.
We are based in Mississauga and work across Toronto and the entire GTA, including Etobicoke, Brampton, Oakville, Burlington, Milton and surrounding communities. We also serve the Hamilton area, including Stoney Creek, Ancaster and Dundas, as well as Guelph, Caledon and Grimsby. If you are nearby but not on this list, ask us anyway.
Yes. Our work is backed by a written workmanship warranty. The warranty terms are provided in writing with your quote, so you know exactly what is covered before the job starts.
In most cases, yes. Cracks can be injected, spalled and pitted surfaces can be resurfaced, uneven slabs can be levelled and the whole surface can be protected with a durable coating. Repair usually costs a fraction of replacement and avoids demolition. When concrete is truly beyond saving, we tell you honestly before you spend anything.
Interior work such as basement floors, garage coatings, interior waterproofing and commercial floors continues year round. Exterior repairs and coatings depend on temperature and curing conditions, so outdoor work is scheduled around the weather. We can assess your project in any season and book exterior work for the right window.
In most cases, no. Repairing, resurfacing and coating existing concrete does not normally require drawings or permits, which is one of the reasons repair is faster and cheaper than replacement. Structural changes or full replacement can be a different story, and if your project touches that territory we will flag it before work begins.
Payment terms are stated clearly in your written quote before any work starts.
It depends on the size and the system, but most residential repairs are measured in days, not weeks. Coatings and overlays need curing time before the surface can take foot or vehicle traffic, and we tell you exactly how long to wait. Full replacement, by comparison, typically means demolition, forming, pouring and weeks of curing.
Yes. Alongside residential work we repair and coat commercial kitchen floors, warehouse floors, expansion joints, condo balconies and other commercial concrete. The repair-first approach matters even more commercially, because it keeps downtime short.
