Basement Waterproofing in Markham, ON
Leaky or wet basement in Markham? TCR Pro waterproofs foundations and repairs cracks with a 20-year warranty. Free inspection & quote.
Markham’s basements range from the century foundations under Unionville’s heritage homes to the poured walls of subdivisions that spread through the 1980s, 1990s and 2000s. Most calls we take here come from the newer streets, where finished rec rooms and rental suites make even a slow leak an expensive nuisance.
The city drains through the Rouge and its tributaries, and lots near those valleys sit on ground that holds water after storms. TCR Pro has been fixing wet basements and damaged foundations since 1998.
Basement waterproofing in Markham subdivisions and heritage streets
In the tract-built neighbourhoods, the standard failure is a shrinkage crack in a poured wall, often behind finished drywall where it drips unseen. We locate the entry point with minimal opening, then seal the crack through its full depth with interior injection, no excavation required.
Where a wall leaks in multiple places or grading has settled toward the house, we look at the bigger picture. The repair may pair injection with corrected drainage, or call for an exterior membrane on the affected wall, and we explain why before quoting either.
Unionville’s older foundations are a separate craft. Stone and early masonry walls need moisture managed rather than simply blocked, usually with interior drainage at the footing and careful repair of the masonry itself.
What working with us involves
We begin with an inspection and a plain-language diagnosis. The written quote that follows fixes the scope and the price, and we do not start until you are comfortable with both.
Because TCR Pro repairs the existing foundation instead of replacing it, in most cases no permits or drawings are needed. Finished basements are protected with proper coverings, and the site is cleaned before we leave.
Basement waterproofing in Markham from our crew carries a 20-year warranty.
Markham also has one of the largest stocks of basement apartments in the region, and a tenant below grade raises the stakes on moisture. A wall that only dampens in spring still feeds mould behind a finished surface, and a rented suite needs that resolved properly, not masked with paint.
We scope repairs for occupied basements with tenants in mind, keeping the work contained and the downtime short.
If you have found damp carpet along an outside wall or a crack that darkens when it rains, request a free estimate. Emailing photos of the spot is often enough for us to tell you which repair fits.
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.
