Basement Flooding Rebate in Markham
Up to $5,000 for Markham homeowners through the City of Markham Private Plumbing Protection Rebate.
Last verified June 2026
Markham's Private Plumbing Protection Rebate offers up to $5,000 per household toward flood-prevention plumbing — backwater valves, sump pumps and weeping tile (foundation drain) disconnection. Pre-approval from the City's Environmental Services is required before any work begins.
Why Markham homes need this
Many Markham homes still have foundation drains (weeping tiles) connected to the sanitary sewer. Disconnecting them and adding a sump pump and backwater valve is the strongest protection against sewer-backup flooding, especially in flood-prone areas.
What the rebate covers
Combined under the up to $5,000 program cap. Per-measure limits may apply — confirm current amounts with City of Markham before you start.
