Deep Dive: What Are You Paying For?
Deep Dive: What Are You Paying For?1. Interior Basement Waterproofing
Cost: $70 – $100 per linear foot.
This is a highly effective “internal drainage system.” We create a trench along the perimeter of your basement floor, install a weeping tile, and cover the wall with a drainage membrane.
Pro Tip: This is the best option for 2026 if you have expensive landscaping or decks outside that you don’t want to disturb.
2. Exterior Foundation Waterproofing
Cost: $150 – $250+ per linear foot.
The “Gold Standard” of protection. We excavate down to the footing, repair the masonry, and apply a multi-stage waterproof coating and dimpled membrane.
Why the price range? Costs depend heavily on the depth of your foundation (e.g., a 6ft vs. 9ft dig) and whether we can use machines or must dig by hand.
3. Foundation Crack Injection
Cost: $450 – $850 per crack.
Using high-pressure polyurethane or epoxy resins, we seal cracks from the inside. This is a permanent fix for structural gaps that allow seepage.
The 2026 Tech Advantage: Smart Sump Pumps & Sensors
In 2026, we are moving beyond basic pumps. DryShield now offers Smart Sump Pump Systems with Wi-Fi connectivity. These systems send an immediate alert to your smartphone if:
There is a power outage.
The pump is struggling with high water volume.
The backup battery is low. Investing in smart monitoring can save you thousands in potential flooring and drywall damage.
Factors That Influence Your 2026 Quote
Every home in the GTA is different. Here is what our Project Managers look for during your free inspection:
Soil Composition: Heavy clay (common in Markham and Stouffville) holds more water and requires more robust drainage.
Accessibility: If our crews have to work in a tight alleyway between Toronto “semi-detached” homes, labor costs may increase.
Window Wells: If water is coming in through windows, you may need a window well drain tied into your weeping tile.
Is it Time to Waterproof? Look for These 5 Red Flags
If you notice any of these signs, your foundation is likely already under stress from hydrostatic pressure:
Efflorescence: A white, chalky mineral residue on your walls.
Cove Joint Seepage: Water appearing specifically where the floor meets the wall.
Musty Odors: A persistent damp smell that doesn’t go away with a dehumidifier.
Hairline Cracks: Small vertical or stair-step cracks in your concrete or blocks.
Peeling Paint: Bubbling or flaking paint near the base of your walls.
2026 Municipal Rebates: Save Money!

City of Toronto: Up to $3,400 for backwater valves and sump pumps.
