Some Kind Words From Our Customers

Anthony Brown
Anthony Brown
We had a leak from two sources in our furnace room, that occurred after a moderate to heavy rainfall. We hired GJ Macrae to excavate by the outside wall, repair the cracks and protect the wall with a membrane and mesh. Part of the trench had to be dug by hand, due to a gas line, and part could be done by machine. The GJ Macrae team were all very skilled and professional, and completed the job in three days. Now the trench has been refilled with the earth and gravel and it will take some time for the ground to settle. We have had a few heavy rains since the job was completed, and our basement is now completely dry! We highly recommend GJ Macrae!

From our initial discussion with Dean through to the completion of the project I was most impressed with knowledge and professionalism. We had foundation damage from a tree root and they took the time to explain what was required and the steps involved in rectifying the situation. I highly recommend GJ MacRae for any foundation work you may need.

Our experience with Gavin went very well. We are very pleased with the quality of work that was done. They did an excellent job repairing the leaks and the cleanup was great too. Gavin was a pleasure to deal with. He was very professional and pleasant. We highly recommend this company.

Honest, courteous, thorough, professional, reliable, on-time, clean and trustworthy. Solved our home’s basement water concerns caused from living on the flood plain (water table). Would definitely recommend GJMacRae Ltd as the company to fix your wet basement. Dean and his crew’s attention to detail solved the various challenges of our 91 year old home.

Dean, came out right away after we noticed water in our basement and provided an estimate. Communication with him was easy and he answered all my questions. Work was done within the week. I had a great experience and will recommend to others.

Gavin and his team did a great job. Right from quoting the job I had confidence they can do the job well and had the experience. Great videos on their website really help you understand what’s involved in foundation repair.
Job was done in 2 days which I was amazed it could be done that quickly! That’s a lot of pails of concrete and rock that had to be shuttled in and out of the house! The guys were all very friendly and let me know everything that was being done and answered all my questions! The bowed wall looks solidly supported now with carbon fibre strapping and the water found beneath the floor is now being safely routed through newly installed Plastic Weeper to our sump. We now have peace of mind that we can finish the basement with no leaks or crumbling walls! Thankyou Gavin, Maggi, Ricardo and Jay!

We would like to express our gratitude to G.J. McRae for the exceptional job they did in restoring our peace of mind. Every time it rained or snowed, our basement would leak, causing us great distress. However, the crew from G.J. McRae arrived promptly, worked diligently, and efficiently resolved the issue. They even left our backyard in excellent condition, cleaning up after themselves. We cannot thank you enough for the outstanding service and for making us feel confident that the problem is now completely resolved. We are so happy to be able to not worry about this any longer.

Workers were on time and professional. Quality and value for money. My only issue was the concrete poured was a little uneven causing a small lip near the drain. We managed to smooth it out. Would highly recommend GJ MacRae Foundation Repair.
