Leaky Basement Problem in Scarborough

If you live in Scarborough, you know how rainy it can get throughout the year. And you also know how many basements are not prepared for it. Many homes in Scarborough lack proper basement waterproofing systems on their foundation walls. This can be a disaster when it pours. Water accumulates around your house when it rains or melts, and the soil absorbs it. Without a barrier, the water leaks through the concrete basement walls and ruins them. Water damage can also lead to mold and mildew growth, harming your health.

But that’s not all. The water pressure from the soil creates cracks in your basement walls, weakening your home’s foundation. Your wet basement becomes a damp, moldy, flooded mess that can cost you much money and trouble. You can prevent all this by waterproofing your basement with GJ MacRae, the best Scarborough basement waterproofing company. We are always ready to help you.

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.

Window Wells

Window Wells Scarborough

Our hand-excavated exterior window well repair solutions are permanent and allow for guaranteed unimpeded drainage all year long.

Why is GJ MacRae Your Ideal Choice For Basement Waterproofing In Scarborough?

First, we thoroughly inspect the basement to identify sources of water infiltration, such as cracks in the walls or floors, improper drainage, or faulty plumbing. It helps us assess the problem's severity and determine the appropriate waterproofing solution.

After inspecting, we excavate the soil around the foundation walls to expose the exterior surface. This process allows for a more comprehensive waterproofing approach by addressing issues outside the basement walls.

The third step is to clean the exterior walls to remove dirt, debris, and loose materials so that we can repair any visible cracks or damage using appropriate waterproofing sealant or patching materials.

Now we should apply a waterproofing membrane or coating to the exterior walls as it acts as a barrier, preventing water from penetrating the walls while still allowing walls to breathe.

Once done applying the waterproofing membrane, we need to install a drainage system, such as a French drain, along the exterior perimeter of the foundation. This system collects water and redirects it from the basement walls, preventing hydrostatic pressure buildup.

Installing a sump pump is our next step in the basement to remove any water that enters the space. A sump pump is typically placed in a pit and automatically activates when water reaches a certain level.

Well, it's time to apply waterproofing sealants or coatings to the interior walls and floors. Sealants or coatings provide an additional layer of protection against potential moisture intrusion.

Finally, we must regularly inspect and maintain the waterproofing system to ensure its effectiveness. So, clean gutters and downspouts, monitor the sump pump operation and promptly address any signs of water intrusion.
