Why Basements Leak in Durham Region
Durham runs from Lake Ontario over the Oak Ridges Moraine to Lake Simcoe, so the ground under your house can be lakeshore clay, moraine sand or rural fill.
Lakeshore clay
Pickering, Ajax, Whitby, Oshawa and Clarington sit largely on clay near the lake that holds water against walls.
Creeks to the lake
Duffins, Carruthers, Lynde, Oshawa and Bowmanville creeks keep groundwater high near their valleys.
Moraine and lakes
Uxbridge sits on the moraine; Scugog and Brock homes near Lake Scugog and Lake Simcoe often have high water tables.
Rural homes
Homes on wells and septic need drainage that does not discharge into the septic system.

Basement Waterproofing in Durham Region: Questions & Answers
Do you really work in Durham Region?
Yes — from Pickering to Clarington and north to Uxbridge, Scugog and Brock. Because it is further from our office, we book inspections ahead and plan job dates with you.
Are there basement flooding rebates in Durham?
We are not aware of large homeowner rebate programs in Durham municipalities in 2026. Check your municipality’s website and ask your insurer about sewer-backup coverage.
My home is on a septic system. Can I still get a sump pump?
Yes. The sump pump must discharge to the surface away from the house — never into the septic system. We plan the discharge line with that in mind.

Interior waterproofing usually costs $50–$120 per linear foot and exterior $100–$250 per linear foot; most full projects are $3,000–$35,000. The inspection and quote are free.
