Wet Basement Toronto

Wet Basement Waterproofing

A wet basement is caused by excess water pressure (caused by heavy rain or melting snow) that is pushed through cracks in your home’s foundation. This pressure can cause major structural damage to the foundation of your home and will also contribute to other moisture-related problems, such as mold and decay. Whether you use your basement for additional living space, storage, or don’t use it at all, if you have a chronic wet basement, leakage or some degree of flooding, you need to address the problem because it will not go away on its own.

Chronic wet basements or water leak problems can reduce the value of your home and many realtors advise their customers to fix their basement before putting their home on the market. Long-term water exposure in your basement can lead to foundation erosion, mold and water-borne bacteria to grow in your basement.

Nusite offers a number of different basement waterproofing and wet basement repair solutions depending on your specific issue. We start by determining the source of the moisture and then recommending an Exterior or Interior method depending on the severity of the leak. We have been a repairing basement leaks in Toronto and the surrounding GTA for over 30 years.

Below is a quick overview of the two methods of waterproofing:

Exterior Wet Basement Repair
Exterior Waterproofing

Exterior Basement Waterproofing

The exterior basement waterproofing method involves excavating and exposing the foundation wall. Next, we clean and inspect the exterior wall for any cracks. Once excavated, the walls are sealed with waterproofing membrane and new drainage (weeping tiles) are placed at the side of the footing. Last but not least, we check the connection of the weeping tile to the drain or sump to make sure it is working correctly.

Interior Basement Waterproofing

The interior basement waterproofing method is ideal for homeowners who are concerned about disturbing the outside appearance of their home, as it ensures that landscaping is not harmed in the process.  With this method, wall vapor barriers/retarders and drip moldings are installed in order to collect water coming from wall cracks and other foundation wall defects. A drain then directs the water to a sump pump and finally the sump pump directs the water out of the basement.

Window Well Repairs

Keep your basement dry with window well drains. All window wells are below ground level; this makes them vulnerable to flooding. Once the wells flood, the water has nowhere to go – except into your basement. The only way to prevent excess water from seeping into your basement is by installing a drain to divert water away from your basement window.

Window wells are the most commonly overlooked part of your home. Simple maintenance and upkeep is one of the easiest ways to prevent leakage into your basement. Clearing out mud, leaves, and other debris every season can significantly decrease the chance a water overflow may occur. In some cases it may be too late to salvage a leaking window well. When this happens it is necessary to call in a professional. Learn more about window well repairs.

Sump Pumps

Keep water where it belongs, out of your basement.

A sump pump is used to remove water that has accumulated inside the sump pit. They are used to direct excess water away from your house to prevent water from entering your basement.

The city of Toronto also offers a sump pump subsidy program, learn more about the program here.

Depending on your specific situation there are a number of different sump pump options. No matter what your specific need, Nu Site will find the best sump pump solution for you. Sump pumps significantly help keep water out of your basement. To have one installed or repaired contact Nu Site at (905) 731-1228 / (416) 622-7000 or fill out an online form

Mark Lipton - Homestars Review

Basement Waterproofing

Our basement leaked! Of course . . . we bought a 100 year old house! But my office needed to be in the basement permanently. I interviewed 10 different companies until we decided on the Steinbergs and their crew at Nu-Site! They are professional, reliable, courteous, honest, and they really make an effort to communicate with the client about every step of the process.

Sara Jack - Homestars Review

Foundation and Waterproofing Repairs

After several years of chronic leaks, we decided to have our basement waterproofed once and for all. The team over at Nusite was professional, answered my questions during the project and stayed within their quoted price....which is always a concern for me when working with contractors. Great job overall

Joshua Persaud - Yellowpages Review

Basement Waterproofing

Had several cracks in my basement wall and they would leak whenever we had a heavy rain. It started about a year and a half ago and seems to have gotten worse over the past 6 months. I tried having my neighbor seal it, but it started leaking again within a few weeks. Called several waterproofing companies and got several quotes. Finally went with Nusite contractors for the job. They gave a reasonable quote and I liked the guy that came by for the estimate. They stayed within budget and cleaned up before they left. It's been almost 3 months now and it seems to be working great.
