Waterproofing Questions, Answered
How much does basement waterproofing cost in Toronto and the GTA?
Exterior waterproofing runs about $50 to $300+ per linear foot depending on depth and access, and interior waterproofing about $50 to $200 per linear foot. All prices are approximate and depend on the specifics of the project. We give you a clear quote after a free inspection.
How long does basement waterproofing take?
A typical interior waterproofing job takes one to two days. Full exterior waterproofing usually takes two to five days depending on the length of foundation being excavated, weather, and site access. We give you a firm timeline after the free inspection.
Do I need interior or exterior waterproofing?
Interior waterproofing manages water that has already reached the foundation with an interior drainage system and sump pump. Exterior waterproofing seals and drains the outside of the foundation. Most homes only need one of the two, and a free inspection tells you which.
Does the City of Toronto offer a subsidy for basement waterproofing?
Yes. The City of Toronto’s Basement Flooding Protection Subsidy Program offers up to $6,650 per property for eligible backwater valve, sump pump, and foundation drain disconnection work completed on or after November 12, 2025. DGI Waterproofing can tell you which of our services qualify.
