As a locally-owned, family-run business, we offer an array of industry knowledge helping us deliver top-quality workmanship and services. We are proud to say that we have been serving homeowners throughout the Greater Toronto Area (GTA) for over 30 years, giving us the familiarity to handle every aspect of your project.
Exterior waterproofing applications address all water seepage and foundation crack issues, which typically come from the outside of the home. Interior Waterproofing installation is a cost-effective alternative to Exterior Waterproofing. Interior Waterproofing repairs basement leaks and keeps basements dry BUT interior waterproofing does not protect your home's foundation from concrete cracks or shifting.
There are multiple techniques that can be used to lower your basement. Choosing the correct basement lowering technique is vital for maintaining the integrity of a home's foundation. At Nusite Contractors, we use a variety of guidelines to determine the safest basement lowering method for the foundation of your Toronto home.
Nusite Contractors Ltd. has over 30 years of experience in structural foundation repairs. Over the years we have faced a tremendous amount of foundation cracks, which has given us the knowledge and experience to help Toronto homeowners with foundation issues of all sizes and complexities. Weak foundations are a serious issue that can cause major damage to a home.
Many homeowners forget the importance of installing and maintaining a sump pump(s). A sump pump is your home's final defence against intruding water and can be a key factor in keeping your basement dry. Our waterproofing professionals will get the job right, the first time.

If you are currently experiencing sump pump issues, basement drain issues, general waterproofing issues, or want to be proactive and install a sump pump, give Nusite Contractors a call.Nusite Contractors Ltd. is here to help you avoid costly water damage in your basement or crawl space.

Outstanding.
We called Nusite to waterproof our house that was built in the 30’s. Waterproofing had to be performed from the inside due to the benchfooting. Gemil was our rep and his knowledge and professionalism was obvious and very much appreciated. The Nusite team came in and the job was quick, clean and stress free. Gemil made everything easy… thanks Gemil!
I would definitely recommend Nusite for all concrete needs.

I cannot express how highly I recommend Nusite. They are highly professional, on time, responsive to questions, considerate to budget while keeping quality and proper finish of the job in mind. Gemil was always available to answer any questions and made the planning and execution seamless. Gemil and his team took exceptional care of all the nuances of the renovation/ construction and kept me fully informed at all times while keeping it organized and as simple as possible throughout the process.

My home was built in the 20’s. I hired NUSITE because my neighbour was using them so I reached out. Gemil was my rep. He is extremely knowledgeable about his craft and passionate about it also. He made daily visits to my home to keep tabs on his staff. He didn’t just secure the sale and bail. My home required benching and waterproofing. Gemil is a walking encyclopedia on construction and water. I learned a lot from him and he has a jovial personality since I was very stressed about my situation. Aside from interior waterproofing I’m doing the same to the outside also over the next year. NUSITE

I am so happy we chose Nusite to waterproof our basement. We had water seepage and a mold smell coming from our basement. Gemil assessed our situation and gave his honest recommendation. It has been 2.5 years since the work has been done and our basement no longer leaks or smells. They are so professional and reliable. We had a sump pump installed and something happened with the pipe internally that was causing a leak. I contacted Gemil outside of regular hours and his customer service was excellent. He got someone to come almost immediately. Lloyd was able to fix the problem and no damage occurred

Hired Nusite to waterproof my house after years of leaks. Brad who came to give the quote was very friendly and knowledgeable and gave me options. The work was done fast. The crew was in and out in a day and a half over a weekend. All the workers were friendly. I would have given a 5 star review, but a couple of things caused a 4. First there was a dependency from what Brad said was to be done to what the foreman thought was to be done. That caused a little stress right off the top, but with calls to the owners that was settled and the quote was honored. I think better communication between office

The Nusite Team did a great job on our basement waterproofing project. Marco and the team were professional and cordial. They worked with us to manage to soil removal and storage to stage it in a way that would be least disruptive to our neighbours. They were responsive to our requests and worked well to solve arising issues. They left our property very clean and tidy.

I would like to give my thanks to Milton, Jacob, Eric and all those at Nusite who helped deliver a long time wish into reality.
I have a backsplit home, and about 40% the footprint of the house is a crawl space which is (3'10") tall.
Naturally, I wanted this "dead" space made more functional.
Basic overview of work:
I wanted the finished product to be 8ft in height.
Two crawlspace rooms to be merged.
Load bearing wall between rooms to be knocked out and replaced with steel I-beam.
Final room footprint is 20' X 20'.
They would need to excavate about 4-5 feet down.

Jerry, Jacob, and Mateo (The prince) just completed waterproofing my house and they did an amazing job. They worked tirelessly and treated my home as it was there own. I am confident that I won't have any leaks in my basement in the future. Thank you to everyone at Nusite for all your great work.

All I can say is that these guys are the best under-pinners / water-proofers in Toronto. Here is why:
Our journey with Nusite began with Jeff. Well spoken and clean cut guy, met us at our home and took the time to really explain everything that would happen. I had a lot of questions as our case was a very special one. He answered everything flawlessly, without being pushy in the least. He really listened to our concerns and was very thorough.
Our home is a semi-detached and we did not want ANY issues with our neighbour. Our home was built in the 1930’s (Old Semi) and part of the soil structure
