"We had water coming in through three different spots in our basement. They found the root cause on the first visit and fixed everything in two days. No issues since."
"Very professional from start to finish. The inspection was thorough, the quote was fair, and they showed up exactly when they said they would. Highly recommend."
"Used them for crack injection on our foundation wall. Quick, clean, and half the price of the excavation quote we got elsewhere. The crack hasn't shown any moisture in 8 months."

View All Service AreasCommon Questions About Basement Waterproofing
Straight answers to the questions we hear most often.
How much does basement waterproofing cost in Toronto?
Costs vary depending on the method and scope. Crack injection typically runs $500–$1,500. Interior drainage systems range from $5,000–$15,000. Exterior waterproofing is $10,000–$30,000+ depending on the length of the wall. We provide a free written quote after inspection.
What's the difference between interior and exterior waterproofing?
Exterior waterproofing stops water from reaching your foundation — it's the most comprehensive solution. Interior waterproofing manages water that has already entered, redirecting it to a sump pump. The right choice depends on your situation, which we assess during the free inspection.
How long does basement waterproofing take?
Crack injection can be done in a few hours. Interior drainage systems typically take 1–2 days. Exterior waterproofing takes 2–5 days depending on the size of the home and site conditions.
Do you offer a warranty on your waterproofing work?
Yes. We offer a lifetime transferable warranty on our waterproofing systems. If you sell the home, the warranty transfers to the new owner — which can also be a selling point.
Is my basement problem an emergency?
Active flooding should be addressed immediately — call us and we'll prioritize your inspection. Slow seepage or efflorescence (white mineral deposits) is serious but not usually an emergency. Either way, don't wait — water damage compounds over time.
Is Your Basement Showing Signs of Water?
Don't wait until it's a flood. A free inspection takes 30 minutes and gives you a clear picture of what's happening — and what it'll cost to fix it.
