Our Industry Leading Services, Since 1975

Say goodbye to leaky basement as we specialize in basement waterproofing services for below grade concrete block, poured concrete, field stone and rubble stone foundation walls. With over 48 years of service in the GTA, get a dry basement backed by the most reliable warranty in the business and see what the GJ MacRae difference is all about.

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 repair methods simply not work? Trust the experts and see why GJ MacRae Foundation Repair 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 all things drainage. Ask us the difference between interior and exterior drainage methods and enjoy the benefit of our expertise!

Basement windows are a great source of natural light and can also act as a designated fire escape, but what happens when window wells begin to deteriorate, clog and leak? Our hand excavated exterior window well repair solutions are permanent and allow for unimpeded drainage all year long, guaranteed.

Sump pumps and sump basins are an integral part of 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 big rain or thaw.

We specialize in basement waterproofing services for below grade concrete block, poured concrete, field stone and rubble stone foundation walls. With over 48 years of service in the GTA and backed by the most reliable warranty in the business and see what the GJ MacRae difference is all about.

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 are pioneers of 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; and all for less than a standard second story addition.

When your foundation walls begin to show signs of cracking or bowing it is generally an indication of severe exterior lateral pressure from tree roots, hydrostatics or poorly draining soil. Click here to find out more about our full line of carbon fiber foundation reinforcement applications.

What Does Foundation Repair Look Like?

We are the information people, since 1975.

During the early 1970’s when residential basements were mainly used for coal, food storage and the occasional hogmánay we were one of the first waterproofing contractors in the Toronto area to fully realize the incredible benefits of a dry, usable basement. We have a come a long way since 1975 to the present time as we have established ourselves as one of the best waterproofing companies in Toronto.

Greater Toronto’s Outstanding Basement Leak Repair

The Greater Toronto area sees its fair share of rain and snow whether you live in Oakville, Hamilton or Downtown Toronto. That factor, amongst others, can lead to the buildup of groundwater and its attendant hydrostatic pressure that forces water through concrete foundation cracks, damaged concrete foundation walls and damaged weeping tile systems and allows water to enter straight into your basement. These concerns demand careful waterproofing and drainage considerations that are rarely implemented in residential structures. This is where GJ MacRae Foundation Repair, as the leading waterproofing company in Toronto can help. We provide weeping tile system services and structural foundation repair services so that your foundation is in perfect condition.

Expert Waterproofing Services for Your Home

Our company has been providing the most reliable basement waterproofing practices Oakville and the Greater Toronto Area has to offer since 1975, bringing decades of experience to each and every foundation repair project. Nobody likes a leaky basement and we know that the only proper repair for a leaking foundation crack is from the exterior of your house, and we use a proven multi-stage repair process based on below grade drainage considerations and a deep understanding of residential waterproofing envelopes. This can include the application of barrier membranes as well as repairs directly to concrete blocks, poured concrete foundation walls, rubble stone and field stone walls coupled with rapidly draining weeping tile systems that protect the foundation drainage envelope from failure. Plus, all of our drainage and waterproofing solutions are backed by the most reliable warranty in the business. After all, the only permanent solution to a leaking basement is the one that gets the job done right the first time.

Excellent service from beginning to end. We would highly recommend this company. Dean assessed the problem (water leaking into our furnace room as a result of a window well that another company had incorrectly installed previously) and provided a thorough estimate detailing every aspect of the project. He then scheduled the job to be done before the big winter storm that had been forecast. The crew arrived exactly on time and completed the job, to the very best professional standard, in less than a day. We are so glad we chose G.J. MacRae. Thank you very much.

FAQs

There are several factors that can cause a wet basement, including poor drainage, foundation cracks, leaks in pipes, and improper sealing of the basement walls or floors.

Common signs of water problems in basements include musty odors, mold growth, water stains on walls or floors, efflorescence (white powdery substance on the walls), and visible cracks in the walls or floors.

We offer a comprehensive range of basement waterproofing services, including foundation repair, basement crack repair, sump pump installation, exterior waterproofing, interior waterproofing and many more.

The cost of basement waterproofing depends on several factors, such as the extent of the damage, the type of waterproofing solution needed, and the size of your basement. We offer free consultations and can provide you with a quote once we assess your specific needs.

The timeline for a basement waterproofing project depends on the scope of the work. Some projects can be completed in a few days, while others may take several weeks. We will provide you with an estimated timeline during the consultation process.
