Testimonials from our clients
Have you noticed excessive moisture or water in the basement? You might need basement waterproofing!
Basement Waterproofing Prevents Flooding
Toronto weather can be unpredictable. Heavy rains and snows can lead to a wet or leaky basement that’s a risk to your home and your health. If you’ve noticed dampness in the basement, that’s a sign your foundation may have cracked. Leaking basements can spiral out of control quickly. Call us for a free, no-risk inspection if you’ve noticed any of the following:
- Moisture in the basement
- A foul, mildew odor
- Mold on walls
- Allergic reactions in the basement area
Our team can offer a thorough, no-cost inspection of your basement and determine the best course of action to prevent further damage. Dr. Pipe’s team of experts offer a variety of interior or exterior waterproofing solutions based on your situation.
Interior Waterproofing
Interior waterproofing works from inside your basement. We can repair cracks with an injectable polyurethane material, or install an interior drainage system of pipes beneath your floor to carry away groundwater to a sump basin.
A sump pump installed in your basement will allow water to collect safely in a basin installed below your basement floor that is then pumped away from the house. We can install both the pump itself and backup power to ensure that if a heavy storm cuts off the main power, your basement is still protected.
A backwater valve installation is another flood prevention option that our licensed plumbers are able to install in your home. Once in place, the backwater valve blocks the line from your house to the city sewer line, allowing water to flow out of your home but not to flow back up into your basement in the event of heavy rains and flooding.
Exterior Waterproofing
Exterior waterproofing allows us to get to the root of the problem outside, where the water first infiltrates your home. This can include repairs to the walls and foundation and installing new, updated weeping tile to drain water away from the foundation of the house to a sump basin or elsewhere.
How Much Does Waterproofing in Toronto Cost?
Every situation is different, but we’re happy to come to your house for a no-cost inspection and determine your needs, then work with you to decide what’s going to be best. Fortunately, the City of Toronto offers significant rebates for flood prevention work, up $3200. We can help you fill out the necessary forms if you qualify for the City of Toronto Flooding Protection Subsidy Program, which can greatly offset any costs.
Fixing basement flooding before it gets out of hand and takes a toll on not just your property but your health will save you much more in the long run.

Waterproofing Process
Step 1: Inspection
We start from a leaking basement, we identified that the result of the leak is cracking in the foundation and old clay weeping tiles.

Step 2: Excavation
We carefully excavate around the perimeter of the house and find all the old clay weeping tiles.

Step 3: Cleaning the foundation and the old clay weeping tiles removing
After excavating we clean the foundation and remove old clay weeping tiles.

Step 4: Pouring a new concrete layer
We put a new concrete layer on the foundation wall to prevent any future cracks that might lead to leaks.

Step 5: New weeping tiles installation
It’s a final step of basement waterproofing. We add new weeping tiles and branch for the window well, for the added security we also membrane and grave on the top of the weeping tile. At this stage the basement becomes full waterproof and it is virtually impossible to break the barrier regardless of the amount of the water flow.

FAQs
What does basement waterproofing involve, and why does it matter?
Basement waterproofing shields your basement from water intrusion through either interior or exterior protection systems. In Toronto’s climate, heavy rainfall, melting snow, and rising groundwater can lead to seepage, damp walls, mould, and even structural damage. Waterproofing keeps your basement dry, prevents moisture‑related issues, and protects your home’s value.
How does professional basement waterproofing function?
A licensed Dr. Pipe plumber or waterproofing specialist inspects your foundation, soil conditions, and drainage. They may install interior drainage channels, weeping tiles, sump pumps, exterior membranes, or full exterior waterproofing systems. These solutions redirect water away from the foundation instead of allowing it to penetrate through cracks or porous concrete.
Should I consider waterproofing if my basement only shows minor water intrusion?
Yes. Even small leaks, damp spots, efflorescence, or musty odours signal early water problems that can worsen over time. Waterproofing eliminates the source of the moisture, helping prevent mould growth, structural deterioration, and costly future repairs.
Can waterproofing prevent water from entering through cracks in the foundation?
Yes. Professional waterproofing typically includes crack repair and the installation of drainage solutions like sump pumps and interior perimeter drains to control water before it enters. For major cracks or exterior pressure issues, exterior excavation and sealing may be recommended. Dr. Pipe determines the best long‑term solution based on your home’s condition.
How much time does basement waterproofing usually take, and what is the typical cost in Toronto?
Project duration and cost depend on basement size, severity of water issues, and the chosen method. Interior waterproofing and sump pump installation often take a few days, while exterior excavation can take longer. Dr. Pipe provides clear, detailed estimates so you understand the timeline, scope, and cost before work begins.
What distinguishes interior waterproofing from exterior waterproofing?
Interior waterproofing controls water that has already entered the basement by directing it into a drainage system or sump pump. Exterior waterproofing stops water from reaching the foundation in the first place by installing exterior weeping tiles, adding membranes, and improving grading or drainage around the home. Both methods are effective, and the right choice depends on your home’s specific needs.
Can waterproofing help reduce basement mould and excess humidity?
Yes. Mould thrives in damp environments, so reducing moisture through waterproofing greatly lowers mould risk. By sealing cracks, improving drainage, and installing waterproofing systems, you create a dry and healthier indoor environment.
How can I determine which waterproofing method is best for my home?
The ideal method depends on the home’s age, soil type, drainage patterns, and severity of water intrusion. Dr. Pipe performs a full inspection of your basement and foundation to recommend the most effective waterproofing solution tailored specifically to your property.
