How to Take Advantage of the City of Windsor’s Basement Flooding Protection Program

waterproofing program windsor

In the last ten years, the city of Windsor has been met with some challenging weather events, making us a city now prone to flooding. Our blog Which Residential Areas in Windsor are Commonly Hit by Flooding dives deeper into the areas of Windsor most at risk from increasingly frequent and severe weather events. In a pursuit to protect Windsor homeowners, in 2011 the City of Windsor developed the Basement Flooding Protection Subsidy Program. You could be eligible to receive up to $2,800 to cover basement flooding prevention costs. We’ve put together the key information below as plainly as possible to help get you started. All necessary links will be at the bottom of the blog.

Eligibility and Requirements

Only existing residential dwellings are eligible, meaning single family homes, duplex homes, and freehold townhomes. The program covers the following:

  • Backwater valve(s) – up to 100% cost ($1,000 max)
  • Sump pump installation with sump pump overflow and disconnect floor drains – up to 100% cost (max $1,750)
  • Sump pump overflow discharge outside to surface (applies to existing sump pumps) – up to 100% cost ($300 max)
  • Installation of backwater valve and sump pump with sump pump overflow – up to 100% cost ($2,800 max)
  • Disconnect foundation drains from floor drain and/or dye testing and camera work as required – up to 100% cost ($400 max)

The program does not cover the following:

  • Replacement of an existing sump pump
  • Sump pump upgrades
  • Additions of another sump pump
  • Installation of a backup sump pump
  • Work performed for which a permit cannot be obtained
  • Supply and install of electro-pneumatic backwater valve
  • Replacement of backup valve (except cast iron would qualify)

There are a few things to be aware of. All eligible basement flooding protection work must be done by a contactor/licensed plumber or master plumber. They need to be able to present a license. If a backwater valve is installed by a contractor, a licensed plumber must verify its installation. Any work done by you, the homeowner, does not qualify for the subsidy. So, no DIYs on this one!

How to Apply

Step 1:

Submit your application online prior to any work starting at https://publicforms.citywindsor.ca/basementfloodingprotection/create
The City of Windsor does an initial screening to determine if the property is within the city of Windsor and if it qualifies for the program.

Step 2:

An Administrative Inspector will contact you to arrange a visit called a “Courtesy Inspection” to see what work is eligible for subsidy through the program. However, during the COVID-19 pandemic, this step is skipped! The have a “Fast-Track” option, where instead they require the contracted plumber to provide the following prior to obtaining a permit:

  • Pre-construction photos of the area of work
  • Completed Pre-condition Assessment Form
  • Completed Declaration Form

Step 3:

Hire a plumber and get the work done. The city recommends not paying the plumber in full until the building permit has an approved final inspection, that way you aren’t paying twice for work that should have been done right the first time.

Step 4:

Once the Building/Plumbing Permit has an approved final inspection, you must remit the following information to get your cheque:

Step 5:

Treat yourself for all your work. Nice job!


These things may be tedious, but it is arguably more tedious to deal with basement flood damage. You could have up to $2,800 of basement flooding prevention costs covered for free by taking the time to apply and see it through.
