Water damage restoration in Markham

Markham sewer backups and stormwater

Markham’s guidance distinguishes sanitary sewer backups from stormwater runoff. The city’s water and sewer programs explain how older downspout connections in parts of Thornhill, Unionville and Markham Village were addressed.

If you see water after a storm, tell MGL whether it came up at a drain or entered at a window, door or wall. The observation helps determine which trade or municipal department should investigate the source and what the interior assessment should cover.

For a condo or commercial property, identify any suites, tenant spaces and shared circulation routes affected. Keep the property manager’s site access instructions with the report so the team can plan which areas to inspect first.
