Brantford's basement flooding grant pays 80 percent, to $5,000

Brantford will pay 80% of your flood-prevention plumbing, to $5,000

The City of Brantford runs a Basement Flooding Prevention Grant that covers 80 percent of costs to a maximum of $5,000, with its own cap for each measure:

• Basement flooding risk assessment: up to $300
• Downspout disconnection: 80 percent, up to $500
• Internal backwater valve: 80 percent, up to $3,000
• External backwater valve (private property only): 80 percent, up to $5,000
• New sump pit and pump with battery backup: 80 percent, up to $4,000

That battery-backup sump line is unusually generous, and it is the one most homeowners do not realize is covered.

The condition that disqualifies people

Read this before you call a plumber: work cannot begin until the City has approved your submitted application. Start early and you have simply paid full price for work that would have been 80 percent covered. The other conditions are straightforward but absolute: you must reside at the property, your property taxes must be paid in full at the time of application, the property cannot be under new-construction warranty, and all downspouts must already be disconnected from City sewers. Backwater valves also require a plumbing permit, currently a $105 fee and the homeowner's responsibility.

"Apply first, dig second. I have watched a homeowner spend four thousand dollars on a backwater valve in March and find out in April that starting early cost them the entire grant. The paperwork is not the annoying part of this job, it is the part that pays for it."

What Brantford says actually causes basement flooding

The City names five causes, and four of them are things you can see from your own driveway:

1. Poor lot grading. The City's guidance is blunt: all homes need lot grading that slopes away from the structure.
2. Poor basement sealing around the foundation.
3. Weeping tile failure. Every home should have a weeping tile or foundation drain system around the structure, and in older Brantford housing stock it is often collapsed or silted shut.
4. Improperly installed downspouts. They should discharge 1.5 to 2 metres (5 to 6 feet) away from the basement wall.
5. Eavestrough debris.

On sewer-connected downspouts, which turn up regularly in older homes, the City is explicit that rainwater then contributes to overfilling sewer pipes and backing them up into homes, and that those downspouts should be disconnected to discharge onto your property.

Grant first, finishing second

If you are planning to finish the basement, the flood work belongs at the front of the project, not after the drywall. That sequencing is exactly what we describe in our Brantford basement page and in the nine-stage finishing playbook, where the moisture assessment is stage one for a reason.

The other Brantford money most owners miss

Brantford and the County of Brant also co-deliver Ontario Renovates, a fully forgivable ten-year loan (forgiven only if you remain the owner-occupant for the full term) for repairs including heating systems, roofs, doors, windows, electrical, plumbing, septic and well service, with priority for energy-saving products, plus accessibility work such as ramps, handrails, chair lifts and height-adjustable counters. It is income-tested with a maximum home value of $350,000, and the current application deadline is October 31, 2026. The City does not publish a maximum grant figure, so ask them directly rather than trusting the numbers third-party sites quote.

Provincial energy rebates stack on top of all of this, and they are covered in our guide to Ontario's renovation rebate programmes.

Other Brantford money worth knowing about

If the repair list runs past flood prevention into the roof, the furnace or the wiring, the City and County also co-deliver a forgivable loan for essential repairs and accessibility work, income-tested with an October 31, 2026 deadline. The mechanics, and the one figure nobody publishes, are in our Ontario Renovates walkthrough.
