Q: How long does waterproofing take?
A: Most interior projects take 2–4 days. Crack injection can be done in one visit. Exterior waterproofing typically takes 3–5 days.

Q: Interior vs. exterior waterproofing — which do I need?
A: Interior systems manage water that has entered through the floor-wall joint. Exterior waterproofing stops water before it reaches the wall. Many Toronto homes benefit from both. A free inspection determines the right approach.

Q: Do I need a permit?
A: Interior waterproofing typically does not require a permit in Toronto. Exterior excavation may require one depending on scope. We handle all permit requirements.
