Water Damage Markham
Water damage Markham homes suffer is often tied to age, because much of the older part of the city was built before modern sewer design standards, and that is why Scarborough Water Damage takes calls there.

Across the line from Scarborough
Markham begins at Scarborough's northern edge, with the Rouge River and its tributaries running through both. Milliken and the older parts of Unionville are only minutes from Agincourt, so a crew based on the Scarborough side reaches them quickly. Markham itself ranges from the heritage streets of Unionville and Markham Village to the newer subdivisions of Cornell and Box Grove, with townhouse developments and condominiums in between.
A crew leaves from our Scarborough office after a call, and we plan the route from your nearest intersection.
What the City of Markham's studies found
The City of Markham has ranked areas for flood-control upgrades according to where basement flooding is concentrated, and Markham Village and Unionville are among its priority areas, together with West Thornhill and the Don Mills Channel. A 2021 flood remediation plan for Markham Village and Unionville notes that most of the area was built before 1978, ahead of updated sewer design standards, and sets out options including storm and sanitary sewer and watermain upgrades.
The City also runs a Private Plumbing Protection Rebate Program for qualified owners who install eligible flood protection devices, and warns residents about phone scams linked to it. Read the current terms on markham.ca, and never pay a caller who contacts you unprompted.
Typical Markham water losses
- Sewer backup through a basement floor drain in an older neighbourhood
- Foundation seepage in the lower level of a house on clay soil
- Frozen exterior hose bibs and garage plumbing lines in January
- Dishwasher, fridge and washing machine supply failures
- Roof leaks that travel down through second-storey ceilings
What a visit from us involves
The crew arrives, stops the source and removes standing water. They then check the structure with a moisture meter and thermal camera and place air movers and dehumidifiers. The drying usually takes three to five days, with readings logged each day. The assessment is free, and we deliver a written scope and price for any rebuilding. We also prepare a clear photo and moisture record, which your insurance adjuster can use.
If water came up a drain, we will not treat it as a simple clean-up. Sewage affects what must be removed, and we explain what that means before any work starts.
Who qualifies for Markham's plumbing rebate
Markham's Private Plumbing Protection Rebate lists conditions beyond the amounts. The property must be in a known flood-prone area or show a flood risk, the owner must have the work reviewed and cleared by the Environmental Services Department before installation, and a licensed plumber must complete a camera inspection of the laterals once the City has cleared the first review. Downspouts must be disconnected from the City's sewer system, and the installation needs a building permit inspected by the Building Department. The City's extended deadlines are April 30, 2027 for the permit and July 31, 2027 for the rebate application (checked November 2026).
