Basement Waterproofing in Toronto, ON
Leaky or wet basement in Toronto? TCR Pro waterproofs foundations and repairs cracks with a 20-year warranty. Free inspection & quote.
Much of Toronto sits on dense clay that drains slowly and pushes water against foundation walls every time a storm rolls through. In older neighbourhoods like Riverdale, High Park and the Junction, century brick semis with shallow footings and narrow side yards make that pressure worse, and wet basements are one of the most common calls we take in the city.
TCR Pro has been repairing and waterproofing concrete since 1998. Our approach is to fix the foundation you have rather than rebuild it, which keeps the cost down, and in most cases no permits or drawings are needed.
How we handle basement waterproofing in Toronto
The right method depends on your house and your lot. On Toronto’s tight semi-detached streets there is often less than a metre between homes, so digging out the exterior wall is not always practical. In those cases we work from inside, sealing the wall and directing water into a proper drainage path so it never reaches your finished space.
Where there is room to excavate, exterior waterproofing is the more permanent fix. We expose the wall, repair the concrete or masonry, apply a waterproof membrane and restore the grading so surface water runs away from the house instead of into it.
Newer infill homes in the city bring a different problem. Poured concrete walls develop shrinkage cracks that weep during spring melt, and these are usually resolved with crack injection rather than a full system. We tell you honestly which situation you have, because basement waterproofing in Toronto is rarely one-size-fits-all.
What a typical job looks like
It starts with an inspection. We look at where the water shows up, check the grading, downspouts and visible cracks, and trace the moisture back to its entry point rather than guessing from the stain on the drywall.
You then receive a written quote that describes the work, the materials and the price. There are no verbal estimates that grow later, and you decide on your own schedule.
On the job itself we protect floors and landscaping, complete the repair as quoted and leave the site cleaned up. Our waterproofing work is backed by a 20-year warranty, so the fix is not something you revisit in a few seasons.
If your basement smells damp, shows efflorescence on the walls or takes on water during storms, call TCR Pro for a free estimate. You can also email us photos of the wall or the leak and we will tell you what we would recommend before anyone visits. Basement waterproofing in Toronto is what we have done for decades, and we are happy to start with an honest look at your foundation.
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.
