I had Bishop Mercier fix my foundation and install a French drain. They dug down, fixed all the cracks, put in the French drain, waterproofed the foundation… even fixed the landscaping with the correct slope to drain water away from the house. Basically they took care of everything from A to Z, with a warranty and all. Very happy with their work.

I hired Bishop Mercier for the masonry cleaning of my rental property in Westmount. The brick and stone were badly stained over the years, but Jim and his team restored the surface back to its original state. The results are outstanding. Very satisfied with these guys.

I had water infiltration when the snow started to melt. I called a few companies, and Bishop Mercier came right away. They were fast to respond and reasonably priced. I gave them the go-ahead and the did a great job. 5 star service all the way. Very satisfied, would definitely use them again.

My house looked in terrible condition because of some damage to my slate roof. Bishop Mercier had the best price, and they worked hard with a large team to get the work finished quickly. My home looks great; very happy with them.

Hired this company to fix my roof. They had the best warranty and have been around for many years. Very happy with the work they did. They worked hard and the roof looks great!
