Foundation crack repair and wet basements in Pickering
From the post-war streets near Frenchman's Bay to Seaton's new subdivisions and the rural hamlets up north, Pickering homes crack and leak for different reasons. Here's what's common in each part of the city and how it usually gets fixed.

Pickering homes and their foundations
Pickering's suburbs started in the south after the Second World War and spread north. The newest wave is Seaton, a planned community of about 21,000 homes, of which around 1,500 had been built by 2022. North of that, the city is still rural.
| Where and when | Typical foundation | What tends to go wrong |
|---|---|---|
| South Pickering by the lake: Bay Ridges, West Shore, Rosebank | Block and early poured concrete from the post-war decades | Seepage where the floor meets the wall, ageing weeping tile, heavy reliance on sump pumps near the water |
| Central neighbourhoods: Liverpool, Dunbarton, Amberlea and around the City Centre, largely 1970s–1990s | Poured concrete | Shrinkage cracks, leaking tie-rod holes, window wells that flood |
| Seaton: new since the late 2010s and still building | Poured concrete with a drainage membrane | Early shrinkage cracks, backfill settling toward the house. The newest homes may still be under Tarion warranty |
| Rural Pickering: Claremont, Brougham, Whitevale, Greenwood | Everything from stone farmhouse foundations to modern poured walls | Old masonry leaks. Wells and septic beds to plan around if anyone digs |
A rough guide only. Your home's actual build year and any past repairs matter more than the neighbourhood.
High water near the lake and the creeks
Frenchman's Bay, Duffins Creek and the Rouge River shape south Pickering, and homes near them sit where groundwater runs high, especially in spring. That shows up as water at the base of the basement wall, a sump pump that runs for days after a thaw, or window wells that fill like buckets when their drain is clogged or was never connected.
- Window wells: clear leaves and debris out of the bottom, check there's a drain with gravel over it, and add a clear cover. If water comes in under the window, the well drain is the first suspect. More on window well leaks →
- Sump pump: test it before March, keep the discharge well away from the foundation, and consider a battery backup.
- Cracks: a crack that only leaks when the ground is saturated is still worth fixing. Injection from inside handles most of them.
If water comes up through the floor drain rather than in through a wall, that's a sewer or plumbing issue for the Region of Durham or a plumber, not a foundation repair.
