GJ MacRae Foundation Repair is an award-winning, second generation family-run Basement Waterproofing company based in Toronto and serving the Greater Toronto Area since 1975.
Say goodbye to leaky basements because we specialize in basement waterproofing in Toronto for below-grade concrete blocks, poured concrete, field stone, and rubble stone foundation walls. With nearly 50 years of service, getting a dry basement backed by the most reliable warranty in the GTA is just a phone call away.
Is there a crack in your poured, block, or rubble stone foundation wall, and is this crack allowing water to leak into your basement? Why do interior crack injection methods simply not work? Trust the experts and see why GJ MacRae carries the most reliable foundation crack repair warranty in the business.
A century-old technology reborn! Our services also include interior and exterior weeping tile systems coupled with deep insights and experience relating to drainage. Ask us about the difference between interior and exterior drainage methods and enjoy the benefits of our extensive expertise.
Basement windows are a great natural light source and can act as a designated fire escape, but what happens when window wells deteriorate, clog, and leak? Our hand-excavated exterior window well repair solutions are permanent and allow for guaranteed unimpeded drainage all year long.
Sump pumps and sump basins are integral to all below-grade drainage strategies due to their simplicity, reliability, low cost, and proven effectiveness. Ensure your sump pump, basin, and battery backup system are well maintained and ready for the next significant rain or thaw.
We also specialize in structural foundation shoring, concrete footing and replacement, concrete foundation wall reinforcement and replacement, structural underpinning installations, and all phases of below-grade concrete foundation repair, reinforcement, and rebuilding.
Are your foundation walls spalling, eroding, or fragmenting? Is this damage accelerating through the years? Stopping moisture penetration through your above-grade concrete structure is imperative. We offer brush parging, s-type, adhesive, mesh, fiber, and thermal-slurry solutions for a lasting barrier.
GJ MacRae pioneered the overflow underpinning method in the Greater Toronto Area. Our underpinning process allows for safe, reliable vertical increases in basement ceiling height that can turn crawl spaces into full living quarters for less cost than a standard second-story addition!
When your foundation walls begin to show signs of cracking or bowing, it’s generally an indication of severe exterior lateral pressure from roots, hydrostatics, or poorly draining soil. Click below to learn more about our complete carbon fiber foundation reinforcement applications.

The Impolite Canuck2024-10-27 GJ MacRae did an amazing job on my cracked foundation. Highly recommend. Guys were professional, punctual, courteous, informative and left zero mess. They even fixed some rod leaks I discovered after the second deluge last August at no extra charge. Peggy Smith2024-08-25 Very happy with a recent job completed by GJ MacRae Foundation Repair at our home. The service was excellent, the owner and working crew were very courteous and knowledgeable about their trade. They completed the work on time and on budget and they did a great job! I would highly recommend this company for any foundation/basement you may have. bklodt2024-07-15 Used GJ MacRae for a foundation repair at our heritage house built circa 1894. The experience was positive from the quoting through 3 days execution of the work. Was done on time and on budget with a hard working crew who were experienced and left behind a strong and waterproof block wall. Gavin the owner was a pleasure to work with. Would use them again if ever needed. Lisa Kemp2024-07-15 G J MacRae installed a sump pump in my house to help with a water problem in my basement. The workers were professional and knowledgeable and took care with the quality of their work. They did an excellent job. I’m very happy with the result and would recommend them. Kyle Yamamura2024-06-21 Highly recommend the team at GJ MacRae. Excellent quality of work and customer service - which is hard to find these days. The waterproofing of my basement was fast, clean and effective - all at a very reasonable price. Thank you! Malique Ouedraogo2024-06-15 GJ MacRae repaired the foundation of my parents-in-law place in May of 2024. They had had a leak for quite some time and even with the heavy rains we had in late May/early June, their basement is now 100% dry. The team was courteous, patient with questions and very honest. They were reliable workers - showing up on time, cleaning up after themselves and tried to be as unobtrusive as they could when working in the house. They worked with a high level of integrity. My parents-in-law would highly recommend this company. Paitra VB2024-06-13 Dean and the team from GJ MacRae were great! Dean was super quick to reach out and come and check out our crawlspace where it was leaking, and got his team in as soon as possible to fix it up. Would definitely use them again! David2024-06-10 GJ MacRae went above and beyond to get our project finished. We're very grateful for their dedication and excellent workmanship! Kent Parker2024-05-25 We love in an attached house in downtown Toronto. A neighbour’s recent renovation to a shared wall uncovered an encroachment issue from 1948 that required us to move our footings. After a few quotes, we decided to work with GJ MacRae Foundation Repair. From the quoting process, careful planning and execution, their work was flawless, expertly explained and done to our (and our neighbour’s) satisfaction. Would 100% recommend.
