From Scarborough up the Don
The eastern half of North York meets Scarborough along the Don River's east branch and Highway 404. Don Mills, Parkwoods, Flemingdon Park and Willowdale are only a short drive from our side, so we respond to them as readily as to nearby Scarborough streets. The City of Toronto's Basement Flooding Protection Program includes Study Area 55, Don River and Eglinton, whose environmental assessment was completed in 2022; the City's map shows it spanning several wards that include parts of North York.
Housing in this corner of North York
Don Mills was planned in the 1950s, with low-slung bungalows and later townhouses clustered along curving streets. Willowdale has deep lots, many of which have been rebuilt with large new houses over finished basements. Along Sheppard and around Don Mills and Finch, there are mid-rise and high-rise apartment and condominium buildings, some more than half a century old. Their risers and stacks are shared, so one failure can reach multiple suites.
The causes we meet most in this area
- Basement storm water in streets that slope toward the creek
- Sewer lines that back up in old buildings when a downstream blockage develops
- Roof drain problems on flat-roofed apartment buildings
- Burst lines during cold snaps in underground garages
- Failed dishwasher and ice-maker connections in condo units
What to expect on the day
When the crew arrives, they stop the source, extract standing water and map moisture with a meter and thermal camera. Equipment goes in, and drying usually takes three to five days, with the readings written down each day. The assessment is free. Before any rebuild, you receive a written scope and price. The photographs and moisture log are prepared in a way an adjuster can follow.
If the water came up through a drain, please do not run taps or flush toilets. That can push more sewage into the house.
Underground garages and mechanical rooms
In high-rise buildings, water losses are not limited to suites. Underground parkades, mechanical rooms and storage lockers can flood from a failed sump, a pipe in the ceiling or a blocked floor drain, and stored belongings are often damaged along with the structure. We work with property managers and condominium boards to cordon off the area, extract water and dry concrete, drywall and wall finishes. Owners whose lockers were affected receive photographs of their own items for insurance purposes.
For houses, the equivalent is the sump pit and laundry area. Check them after any heavy rain, especially after a power cut, because a pump that has stopped is a common reason a basement floods.
North York owners and the City's subsidy
Across the boundary in North York the same City program applies, since both are parts of Toronto. Eligible protection work finished on or after 12 November 2025 earns a refund of 80 percent of the invoice, within the ceilings of 1,600 dollars per backwater valve, 2,250 dollars for a sump pump with alarm and 400 dollars for weeping tile capping, and 6,650 dollars for any one property. These are City program limits, not our prices; our assessment is free and a written scope and price come before any repair work.
Check that your contractor holds a valid City of Toronto business licence before work starts, because the City will refuse funding without one.
