What Is Basement Waterproofing?
Basement waterproofing protects your home by stopping water from seeping through the foundation. In Toronto and across the GTA, clay soil, heavy rain, and freeze-thaw cycles put constant pressure on basement walls. Without proper protection, cracks and leaks can lead to flooding, mold, and costly repairs.
At DrainPro, we use proven solutions like exterior waterproofing, interior drainage systems, and sump pump installation to keep your basement dry year-round. Our licensed technicians tailor every system to your home’s unique conditions for long-term peace of mind.
Signs You May Need Waterproofing Service
Damp walls or musty smells – indicators of hidden leaks.
Visible cracks in foundation walls or floors – water often follows these paths.
Mold or mildew growth – a serious health concern linked to moisture.
Basement flooding during heavy rain – sump pump or drainage system failure.
Pooling water near the foundation – poor grading or drainage issues.
If you notice any of these, DrainPro’s experts can provide exterior waterproofing, interior waterproofing, foundation crack repair, or sump pump installation in Toronto to stop water at the source.

Myths About Waterproofing
Many homeowners think painting or applying DIY sealants will solve basement leaks. In reality, these quick fixes rarely hold up against heavy rains or high groundwater. Proper protection requires professional solutions like exterior waterproofing, weeping tile replacement, or sump pump installation to keep your foundation dry.

Christina M. – Brampton, ON
“We had water leaking into the basement after every heavy rainfall. Oleksandr and his crew excavated one side of the house, installed new weeping tile, and sealed the foundation. They explained everything clearly and the work was very professional. No more leaks since. Cleanup was also great.”

What is a backwater valve and how does it work?A backwater valve is a plumbing device installed on your main sewer line to prevent sewage from backing up into your home. During heavy rainfall or sewer overload, the valve flap automatically closes to stop water and sewage from flowing backward into your basement. It’s one of the most effective ways to prevent basement flooding in Toronto and the GTA.
-
Do I really need a backwater valve in the GTA?Yes if your home has a basement and is connected to the city’s sewer system, you are at risk during heavy storms. It's recommended to install backwater valves to protect your home from sewage backups and even offers a subsidy program to help cover installation costs.
-
How much does a backwater valve installation cost?The cost typically ranges from $1,500 to $3,500, depending on your home's plumbing system, accessibility, and permit requirements. The City of Toronto’s Basement Flooding Protection Subsidy Program offers homeowners up to $1,250 back to help offset the cost.
-
How long does the installation take?In most cases, backwater valve installation takes one day. Our DrainPro team handles everything from initial inspection to concrete restoration, ensuring a smooth and efficient process with minimal disruption to your home.
-
Is a permit required for backwater valve installation?Yes most municipalities, including Toronto, require a plumbing permit before installation. Don’t worry DrainPro takes care of the entire permit process for you, ensuring everything is up to code and subsidy-compliant.
-
How do I maintain a backwater valve?You should inspect your backwater valve every 6 months. Open the clear cover and check for debris, wear on the rubber seal, and proper flap movement. DrainPro will show you how to do this during installation and offers maintenance services if needed.
-
Will a backwater valve stop all types of basement flooding?A backwater valve protects against sewage backups from city sewer lines. To protect against groundwater or stormwater flooding, you may also need a sump pump or weeping tile system. We offer full basement waterproofing solutions ask us about your options.
