What Homeowners Say
Dry basements across Southern Ontario — in their words.
“Our basement flooded twice in one spring. DryFort quoted exactly what the website said, no games, and the crew left the yard cleaner than they found it. Two storm seasons later, bone dry.”
“Called at 2 AM with water pouring in. A real person answered, a crew was here before sunrise, and they walked us through the permanent fix without any pressure. Can't recommend them enough.”
“They installed our sump pump and battery backup and helped us claim the municipal subsidy. Straight answers, tidy work, fair price. The power went out in a storm last month — the backup did its job.”
Waterproofing FAQs
Straight answers about cost, coverage and what actually fixes a wet basement.
How much does basement waterproofing cost in Southern Ontario?
Exterior foundation waterproofing starts at $275 per linear foot (with a $4,000 minimum job) and includes excavation, membrane, drainage board and new weeping tile. The exact rate depends on excavation depth, access and site conditions, which is why we confirm the final price on site. Interior waterproofing is $120 per linear foot ($2,800 minimum), with sump pump and backup battery quoted separately. Crack injections and other work are quoted per project. Every quote is free, written and itemized, for both residential and commercial properties.
Do you really offer 24/7 emergency waterproofing service?
Yes. DryFort runs true 24/7 emergency flood response across Southern Ontario — nights, weekends and holidays. Call our emergency line and a crew is dispatched to extract water, find the entry point and stabilize your basement, followed by a clear plan for the permanent fix.
What areas does DryFort Waterproofing serve?
We serve all of Southern Ontario, including Toronto and the GTA, Mississauga, Hamilton, Burlington, Oakville, St. Catharines, Niagara, Kitchener–Waterloo, Guelph, Brantford, London and the surrounding communities.
Should I choose exterior or interior waterproofing?
Exterior waterproofing is the most complete, permanent solution because it stops water before it reaches your foundation. Interior systems are the right choice when excavation isn't practical — tight lot lines, additions or finished landscaping. We assess your property for free and recommend whichever actually fits your situation, not the biggest ticket.
Is your work guaranteed?
Yes — exterior waterproofing carries a transferable 25-year warranty and crack injections carry a lifetime warranty. DryFort is fully licensed and insured for residential and commercial work.
Do you handle commercial waterproofing?
Yes. We waterproof commercial and industrial foundations, parking garages, and multi-unit residential buildings, with scheduling built around your operations and volume pricing on larger runs.
