ABOUT US

For over seven years, Joint Seal Waterproofing has been providing concrete repairs and waterproofing services in Toronto, the GTA and the surrounding areas. We specialize in thin patch applications and expansion joint injection.

 

High-strength concrete adhesives allow us to perform all concrete repairs from inside the elevator pits and underground parking garages, saving on costs and ensuring long-lasting results. The use of polyurea-based waterproofing membranes restores water impermeability of the repaired concrete.

We offer a full range of waterproofing services for commercial structures.

TESTIMONIALS

It's been a crazy couple of months due to coronavirus, but unfortunately this was called as an emergency has erupted in this household. There was a leak and unfortunately, my family and I stayed elsewhere in the meantime while minimal workers fixed the leak up. Once done, we had the house sprayed down and full on cleaned before coming in. We are now 3 weeks in and we are all fine and the leak is fixed. Thankfully, these essential workers are still working tirelessly. We are super thankful and grateful they are working at times like this. We hope everyone is safe. I can also assure you that they are clean, to themselves and prepared with the right necessities like gloves, etc.

When my wife and I purchased our home on the inspection report, it called out the unprofessional repairs to our balcony outside our master bedroom. So when we were able to save for this repair, we searched the internet for the best company to fix the balcony. After an extensive search and a couple of bids, we settled on Capital Deck & Stair Waterproofing.

WE MADE THE BEST DECISION!

Capital Deck & Stair Waterproofing is a family-owned business and proud of their work. They had fantastic customer service from start to finish.
