I had a leak in my basement as the snow started to melt. After that happened I called Canada Waterproofers, and a technician Slava came to inspect it within hours after my call. Turns out it wasn’t a wall problem. It was my window leaking because the window well wasn’t installed properly and didn’t have a drainage pipe. The next day after the initial visit a crew came in the morning, dug down to the footing and waterproofed the wall, with a proper drainage tube up to the top of the soil in the window well. Finished with gravel and clean all around. Amazing work. I highly recommend them. Great price for work done.
