What Our Clients Have to Say
Renee Smith,
Oakville
I can’t say enough good things about KOME Waterproofing! From start to finish, they were professional, hardworking, and an absolute pleasure to have around. They tackled the moisture issues in my basement with incredible attention to detail, and you could tell they truly cared about the quality of their work. They were always upbeat, cracking jokes, and somehow made a stressful home repair feel like a breeze. Even the inspector mentioned how impressed he was with their craftsmanship! Now, my basement is completely dry, and I have peace of mind knowing it’s protected for years to come. If you’re looking for a team that delivers top-notch work with a smile, look no further—KOME is the best in the business!

I hired KOME to waterproof my basement and couldn’t be happier with the results. The team worked efficiently, kept everything clean, and completed the job faster than I expected. They were professional, friendly, and took the time to explain every step of the process. Now, my basement is dry and protected, and I have complete peace of mind. Thank you, KOME, for the excellent work!
Sam M,

I had been thinking about lowering my basement for a long time and finally decided to go with KOME after getting several estimates. I’m so glad I chose Misha and his team! They were professional, polite, and truly took pride in their work. The crew was always on time, worked efficiently, and completed everything right on schedule. The quality of their work speaks for itself. Huge thanks to KOME for an amazing job—I’ll definitely be recommending them to family and friends!
