Yes, if your home flooded on or after July 8, 2013. Mississauga's Flood Resilience Rebate lists corrugated steel window wells and covers, paying 50% of eligible costs up to $3,000. The cover must never trap anyone in a basement bedroom.
A window well is a small hole that collects a lot of rain. On a basement that has already flooded once, the well and its cover are one of the cheaper places to cut that risk. Here is what the City and Credit Valley Conservation say about them, and the one rule that should shape which cover you buy.
What the City lists as eligible
The City's Flood Resilience Rebate pays 50% of the cost of eligible upgrades, up to a maximum of $3,000. It goes to the registered owner, an individual rather than a company, of a detached, semi-detached, duplex or townhouse in Mississauga whose home had flood damage from an intense rainfall event on or after July 8, 2013. The City's page lists "corrugated steel window well and cover" under its exterior upgrades. It pays for materials, contractor labour and the applicable tax. The owner also needs to have no outstanding City taxes, fees, charges or by-law violations at the property, and only one owner per address can receive the rebate.
The materials guide the City publishes with Credit Valley Conservation lists the two items separately: "Corrugated steel window wells" and "Window well covers". The page and the guide do not give a price or a maximum for either item, so the general $3,000 cap is the only number to plan around.
What a well and a cover actually do
Credit Valley Conservation says a corrugated steel window well that fits tightly against the foundation wall can keep below-grade drainage from seeping into the well. It adds a condition: the well only helps when there is effective drainage away from the foundation wall. A cover, in its words, can further prevent rainwater from accumulating in the well.
That is a narrow job. A cover keeps rain, leaves and snowmelt out of the well. It does not fix a cracked foundation, a failed weeping tile or a sewer backup, and none of those are addressed by the guide's window well section. If water came in through the floor drain or a wall crack, the window well was probably not your problem.
The escape rule that limits your choices
The same guide says plainly that window wells and covers must not inhibit egress from windows that serve as fire escape routes. In a basement bedroom, that window may be the way out.
The City of Ottawa's building code advisory, reviewed under the 2024 Ontario Building Code, sets out what a bedroom egress window needs under article 9.9.10.1: an unobstructed opening of at least 0.35 m² with no dimension under 380 mm, openable from the inside without tools, and a clearance of 550 mm in front of the window with continued egress out of the well. Where the well is more than 1000 mm deep, the advisory says a way to help the person climb out is needed. Ottawa's advisory is not Mississauga's, but it interprets the same provincial code. Confirm any edge case with Mississauga's Building Division.
Read together, that points in one direction. A cover that has to be unlocked from outside, screwed down, or is too heavy to push up from inside the well is hard to square with either statement. That is my reading of the two sources, not a rule either one states in those words. If the window serves a bedroom, choose a cover you can lift or swing open from inside the room and the well without tools, and test it with the window open before the contractor leaves.
Who can do the work
The City defines a contractor as someone qualified in their skilled trade in Ontario who holds valid licensing, as applicable. Labour is eligible only if a valid contractor performs it, and business licences are not required for this rebate. Setting a steel well and cover is not itself a licensed trade, so the invoice is the point: the City asks for the contractor's name and licence number, and a Rhodex craftsman or anyone else you hire should be ready to put that on it. The City says it does not recommend or work with contractors, so the check is yours.
If the job also means digging down beside the foundation to fit the well, or touching drains, ask that work to be itemized separately. The City's list has its own lines for other measures, and a mixed invoice makes it harder to see what is eligible.
The paperwork the City asks for
- A City tax bill showing your name as registered owner.
- One proof of flooding: an insurance claim, correspondence with 311, a Councillor's office or City staff, cleanup or repair invoices or quotes, or date-stamped photos of the flooding.
- Proof of purchase or completed work and payment: original material receipts, or original work invoices.
- An invoice showing the work address, the contractor's name and licence number, a cost breakdown and the total paid in full.
- Photos of the installation, taken before soil is backfilled around the well.
- A condo board authorization letter, if the work falls under the board's jurisdiction.
Online uploads must be 50 MB or smaller per file, in JPEG, JPG, PNG, GIF, PDF or WebP format. The City's page does not state an application deadline or say whether this rebate needs approval before work starts. It says rebates are paid until funding runs out or the application period expires, so email floodrebate@mississauga.ca or call 311 to confirm before you spend money.
A sensible order for the job
- Confirm you qualify: registered owner, eligible home type, and a record of a flood on or after July 8, 2013.
- Check which basement windows serve bedrooms, and measure how deep each well is.
- Ask the City whether you need approval before the work.
- Get a written, itemized quote with the contractor's licence number.
- Photograph the old and new wells, then test the cover from inside.
- Pay in full, keep the invoice and receipts, and send them with the application.
Quick answers
Does Mississauga's flood rebate cover window well covers?
Yes, the City lists a corrugated steel window well and cover as an eligible exterior upgrade. The rebate is 50% of eligible costs, up to $3,000, for homes flooded on or after July 8, 2013.
Can I get the rebate for a cover if my basement never flooded?
No, the City requires flood damage from an intense rainfall event on or after July 8, 2013, plus one proof of that flooding. A cover on a home that never flooded does not qualify.
Can a window well cover block my basement escape window?
No. Credit Valley Conservation says covers must not inhibit egress, and the Building Code expects a bedroom egress window to open from inside without tools.
Do I need a licensed contractor to install a window well cover?
Not necessarily for the work itself, but the City pays labour only for a valid contractor. The invoice must show the contractor's name, licence number and cost breakdown.
Where can I get a fixed price for window well work?
You can request one from Rhodex. Whoever you hire, ask for an itemized invoice that separates the wells and covers from other work.
