What these programs have covered
Halton Region has, in past years, run a basement flooding mitigation program offering homeowners partial reimbursement for certain work. Similar programs exist in other Ontario municipalities. Measures that programs like this have generally supported include:
- Fitting a backwater valve to the house sewer.
- Installing a sump pump and pit where foundation drains connect to the sanitary sewer.
- Disconnecting foundation drains from the sanitary sewer.
- Disconnecting downspouts from the sewer system.
Eligibility, amounts and conditions change over time. Always check the current terms with Halton Region before you book any work.
How such programs usually work
- Check eligibility on the Region’s website or by phone.
- Apply before work starts if pre-approval is required.
- Get permits from the Town where needed.
- Hire a licensed plumber and keep detailed invoices.
- Pass inspection and submit receipts and photos as required.
Do not skip step two. Work done before approval may not qualify, if the program requires approval first.
Insurance and records
Some insurers want to hear about backwater valves and sump pumps when setting coverage for sewer backup. Keep your invoices, permit records and photos together in one place. They help with insurance questions and when you sell the house.
How we help
We can look at your basement, explain which measures make sense for your house and give you the details you need for an application. We will not tell you a subsidy is available when we are not sure; the Region has the final word. Our pages on sewer line repair and backwater valves describe the work itself.
Questions we get asked
Is the Halton subsidy still available?
Programs change. Check the Region’s current terms directly before booking any work.
Can I do the work myself and still claim?
Programs typically require licensed work, permits and inspection. Check the conditions.
Does a subsidy cover the whole cost?
Usually only part of it, up to a set limit, if the program is running.
