Hi John, It’s been a few years since you repaired foundation leaks in my basement. I remember you saying you had some rogue crews out there that caused some issues including work done to my house however you were kind and repaired everything fully. Just wanted to thank for a basement that my family enjoys, a dry basement! and for making things right. Well done John and happy new year…Having a few beers in my dry basement thanks to you!

Foundation Repair I loved these guys. From the get-go, Noreen made the process easy to understand, and everything was within budget. My family was very happy with the work performed within the basement/foundation. Work was not late, and budget was not exceeded. These guys were clean AND polite. Recommended.

Fixed major foundation problem In the summer of 2009, after interviewing a few contractors, we hired GJ MacRae to fix a major walkout / foundation problem on our 37 year old house in Bolton. One wall of our foundation had tilted inward, and had sustained substantial cracks. Consequently, water was penetrating into our finished basement. Needless to say, it was a very stressful time, and the worry and distress it caused us as a family was significant.

From the very beginning of the repair process, the people at GJ MacRae instilled confidence, and exuded professionalism. You could tell John and Gavin knew what they were talking about, and they assured us the job would be done properly and on time. They allayed our worries and fears, and throughout the 3 week process, Gavin communicated what was happening and consistently delivered updates and returned phone calls (even after hours). His calm demeanor and pleasant and professional approach was a welcome and reassuring thing in a world full of pseudo-contractors and fly-by-nighters, who seldom return calls or perform adequately.

GJ MacRae came in and did exactly what they promised they were going to do. The job was completed in exemplary fashion–on time and for the price quoted. The repair site was left cleaner and neater than when GJ MacRae found it, and the quality of the workmanship was superior. Overall, we couldn’t be happier about the quality of service we received.

GJ is a company I wholeheartedly endorse, and I would recommend them to anyone experiencing foundation issues. You won’t be disappointed!

Foundation Repairs I am pleased to be able to provide a testimonial in support of Kevin McQuade. We have used his services on more than one occasion for unrelated matters. The nature of the work required was determined in a timely fashion. The work was completed on schedule and our premises were left in a clean state. We were very pleased with everything associated to the task at hand. Additionally there were no surprises on the quotation. I would have no hesitation in recommending Kevin.

Foundation Work Not only was the actual foundation work completed by the MacRae crew absolutely first rate, the outstanding service provided by the whole MacRae team was outstanding beginning to end. We received pro-active calls from them to advise of timing, the crews arrived exactly on-time everytime, and everyone continued to inquire if the work was being completed to our satisfaction until the project was finished. A great experience. ….And to everyone our sincere thanks.

Foundation Repair MacRae was very responsive to our needs. The job was completed without delay, and of absolute top quality. The crew took care of our property, and everyone we dealt with at MacRae, was very professional. I highly recommend them!
