Water coming through a cracked poured wall? Flat published pricing, a transferable lifetime warranty and one-visit repairs — with straight answers about what Oshawa rebates do and don’t cover.
Coverage: We service Toronto, the GTA and Southern Ontario, and Oshawa is the eastern anchor of that map — crews are in Durham Region week after week, with travel already built into the flat pricing below. Assessments are free, and most injection repairs are finished in a single visit.
Foundation crack repair in Oshawa costs a flat $750–$1,000 per crack for polyurethane injection and $850–$1,500 for structural epoxy, with 5% off every additional crack. No City of Oshawa rebate applies to crack repair — and no permit is needed either: oshawa.ca lists basement waterproofing repair among projects that do not require one. One visit, warrantied for life, transferable when you sell.
A prehistoric shoreline, a century of housing stock and a documented flood record.
Draw a line across Oshawa between the lake and the Oak Ridges Moraine and you trace the shoreline of glacial Lake Iroquois — a boundary Durham Region still maps and publishes today. That old beach band is sand and gravel, and the conservation authority for the area describes it simply: water percolates through easily and is stored as groundwater. After a July downpour or the March melt, that stored water becomes hydrostatic pressure against basement walls, and a hairline crack is its path of least resistance.
The housing stock does the rest. Much of Lakeview, Central and O’Neill dates to the pre-war and early post-war years, so those walls have had 70–100 years to settle and crack. McLaughlin, Vanier, Donevan and Eastdale are largely post-war through 1970s builds. North of Taunton, Windfields and Kedron are still being built out — and young concrete throws shrinkage cracks in its first few years, which is why we inject as many 5-year-old walls as 90-year-old ones.
Durham’s flood record argues against waiting. In the summer of 2008, rainfall running up to four times the monthly average flooded at least 150 basements in one Whitby-area event, and the Region now runs a dedicated Flood Ready Durham program. The Region’s basement-flooding guidance is just as direct about whose job the wall is: a leaking foundation or wall is the homeowner’s responsibility.
Two resins, one visit — matched to the crack, not the sales pitch.
Leaking, damp or actively weeping cracks get expanding polyurethane ($750–$1,000): it chases water through the full thickness of the wall and stays flexible through Durham freeze-thaw. Cracks that are widening, stair-stepping or letting a wall move get structural epoxy bonding ($850–$1,500), which welds the concrete back to full strength. Leaking tie-rod holes run $75–$150 each, and every crack after the first is 5% off. Not sure which crack you have? Start with how injection actually works, or go straight to the published price ranges — the same flat numbers apply in Oshawa as everywhere we work.
Real jobs from our crews — before and after the resin goes in.
What money exists, what it covers, and the paperwork you can skip.
| Program | What it offers | Crack repair covered? |
|---|---|---|
| City of Oshawa rebate | None — the City has no basement-flooding rebate or subsidy program | No |
| Durham Region Basement Flooding Loan | Interest-free loan of up to $3,000 toward an approved backwater valve and sump pump after a sanitary sewer backup, repaid over up to 3 years on the water bill | No — plumbing measures only |
| Provincial rebate | No provincial homeowner program identified | No |
Two honest notes on that table. First, we are injection specialists, not plumbers — the loan’s valve-and-sump work belongs to a licensed plumber and needs Region approval, so confirm current terms with Durham Region Works at 905-668-7711 before you count on numbers first published in 2009. Second, the absence of a rebate cuts both ways: nothing offsets the bill, but nothing complicates it either. The repair is flat-priced from $750, and the City’s building-permit page lists waterproofing repair of a basement among projects that need no permit — so an Oshawa injection is booked, injected and warrantied with zero municipal paperwork. Finishing the basement afterwards is different: that renovation usually does need a permit, which is one more reason to seal the wall first.
Four questions, instant range — polyurethane or epoxy, multi-crack discount included, no obligation.
From first call to dry wall, usually inside a week.
Call or send photos and we quote most Oshawa cracks the same day. On site, the assessment is free; when injection is the right fix, the crew usually completes it in the same visit — roughly 60–90 minutes per crack, working from the basement side with no digging in a frozen yard. Injection works year-round, though the spring melt is our busiest Durham season, so March books up fast. There is nothing to file with the City, and your warranty paperwork arrives by email the same week.
Same flat ranges — these are the variables inside them.
Pre-war walls in Lakeview or O’Neill sometimes call for epoxy and surface prep that pushes a crack toward the top of its range; a full-height shrinkage crack in a Windfields two-storey simply uses more resin than a hairline; and a finished basement adds access work, not a different price list. Multiple cracks pull the total down — every one after the first is 5% off. The full math, with the 30-second calculator, is on the crack injection cost page.
Lakefront to Columbus, one flat price sheet.
Lakeview, Central, O’Neill, Vanier, McLaughlin, Donevan, Eastdale, Farewell, Pinecrest, Centennial, Samac, Northglen, Taunton, Kedron, Windfields and Columbus — plus the rural edges beyond. Nearby: our Markham page covers York Region conditions, the full service-area list holds every city guide, and Whitby, Courtice and Bowmanville homeowners are served from the same Durham routes.

No. The City of Oshawa has no basement-flooding rebate program, and no government program anywhere covers crack injection. Durham Region offers only an interest-free loan of up to $3,000 for a backwater valve and sump pump after a sanitary sewer backup — plumbing measures installed by a licensed plumber, not wall repairs. Budget from our flat pricing instead: polyurethane $750–$1,000, epoxy $850–$1,500, free assessment first.
No — the repair itself is permit-free. Oshawa’s building-permit page lists waterproofing repair of a basement among projects that do not require a permit. The line to watch is what comes next: finishing or altering the basement usually does require one, so seal the wall first, then pull the renovation permit. We schedule repairs so your contractor can close the wall the same week.
You are. Durham Region’s basement-flooding guidance states plainly that a leaking foundation or wall, a blocked private drain or a drainage problem on your property is the homeowner’s to repair; the Region steps in when the municipal sewer main itself backs up. That is exactly why the repair should carry a transferable lifetime warranty — you book it once and the paper follows the house.
The former glacial shoreline mapped through Oshawa left a band of sandy beach deposits that soak up rain and meltwater and hold it as groundwater. Homes on or near that band see pressure spikes against their walls a day or two after big weather, which drives water through cracks that stay dry all August. If your leak follows storms on a delay, that is the pattern — and injection seals the path for good.
Not automatically, but they deserve a real look. Eight decades of settlement produce both harmless hairlines and cracks that have slowly widened, and the free assessment tells them apart. Stable leakers get polyurethane; anything showing movement gets structural epoxy. Either way the fix is one visit — in older Oshawa homes, age changes the resin choice more often than it changes the price.
Very. Poured concrete shrinks as it cures, and vertical shrinkage cracks commonly show up in a home’s first few years — Windfields and Kedron are full of walls at exactly that age. Most are injectable in about an hour. If the home is under seven years old, raise builder-warranty timing at the assessment; either way, sealing early keeps a cosmetic crack from becoming a wet finished basement.
