What Our Clients Say

Had water coming through a wall that was causing mold. They showed up on time, on budget, and did a GREAT job. If you can, ask for a fellow named Colm. He’s the best. Would use again and recommend.

Basement Waterproofing

We are very happy with another fine job from A&A Masonry. Several years ago A&A did a superb job of interior waterproofing in our basement. This time we needed repairs to the exterior where water was coming in through a breach at the point where our old foundation meets a newer extension – which had never been waterproofed by the builder. Alex and his crew dug down to the footings (by hand!) and worked their magic in a very cramped spot between ours and our neighbour’s house, repairing some ‘impressive’ cracks and adding new state-of-the art waterproofing membranes and drainage tiles. Thanks again to all the team at A&A.

A&A Masonry was the right company to chose. The crew did a great job working in a very confined space. The site was kept tidy and secure and the clean up was excellent. Initially Brad, and then Alex communicated regularly about the start date and then the progress. I am a satisfied customer.
