Thorough in his inspection
Haithem came in to do a consult on my Basement and to assess if there was any foundation issue. He was thorough in his inspection and took his time to answer my questions patiently. He assessed the crack in my basement wall and ran through the options available. Very happy with my experience with him and I am glad to have received his advice on my situation.
Knowledgeable and incredibly responsive
I was very pleased with the service the Basement Systems Toronto team provided from start to finish. The sales representative, Haithem, was knowledgeable and incredibly responsive, both before and AFTER I signed the contract. We spoke several times leading up to the installation and he even made a 2nd trip to our house to help us plan for our new sump sump. The installation team was also very professional, did an excellent job working within our parameters (we had some unique requirements given our basement is finished) and made sure to clean up after themselves. Haithem went above and beyond after the installation by helping get me the Toronto Business License Number I needed to submit my rebate request from the city. Great job team!!

5/5 without a doubt
Top notch work from NuSite, I was very impressed with the response time. Also provided two options to fix the cracks in my basement foundation. The quotes were affordable and I think the reliability of the staff member Lee Hollander made me feel comfortable to go with Nusite. I also went with Nusite since they dig by hand and don’t use heavy machinery around my house. I would highly recommend using Nusite and dealing with Lee to any of my friends or colleagues that need waterproofing done. 5/5 without a doubt. — Bryan, via Google
We are pleased with the outcome
We worked with Milton F. from Nusite who was great – responsive and informative. We had deterioration of the foundation of our home, and water seepage in the basement. Nusite did a terrific job repairing and waterproofing the foundation. From the initial coordination of a structural engineer assessment to identify the approach that the repair need to take, through to the dig and repair, the work was done in a timely and in a professional manner. We are pleased with the outcome as we have had a number of rainstorms with a nice and dry basement! The work was exceptional although the coordination in the back office could be improved. However, they were responsive to our feedback, which was great. — J Benett, via Google

Offered me a price that no one else could beat
Last january i noticed a leak in my basement from the winter thaw. Couldnt find where the leak was comimng from. Called a around a dozen companies to figure out the problem. Majority of the other companies stated that i needed to have my entire house water proofed and it would cost between 10 to 15 thousand dollars. Andrew from aqua tech came by and diagnosed where my leak was comming from in 2 minutes. He said i only needed to repair a foundation crack. He offered me a price that no one else could beat. He advisd me to call other companies and get quotes. I did call other companies and no one else best his quote. I called him to do the repair and he repaired it a few days after while i was at work. Now i have a dry basement. Thank you aqua tech. A few months later after very heavy rainfall i noticed some water entering my basement again from another location. I called andrew again and he founf a crack by my a/c unit. Again he repaired the crack within a few days. If i ever need any waterproofing done i am only calling aqua tech. Whenever anyone is looking for a waterproofing company i always pass on andrews number thanks again. — Kelvin Mahadeo, via Google
High-quality work, a fair price, and all done as scheduled
We had a minor water leak damaging the interior finished walls in our family room. Eugene inspected the home, gave us a quote and yesterday, an amazing team came out to locate and repair the fault. They worked tirelessly, digging down 9½ feet to expose the foundation, found and fixed the crack, covered the entire surface with various layers of protective and waterproof membranes, replaced everything, including plants, and when they were done, the area looked exactly as it did before they began. High-quality work, a fair price, and all done as scheduled. This is an excellent company to work with. — VOLODYMYR KRYVDA, via Google

“Good basement waterproofing contractors. High quality work and materials, professional and polite employees. I satisfied with the price and service approach i have got from this company. The reason of the four star rating is that it took them one day longer to complete the job then it was promised. But anyways I definitely will recommend strong basements to anyone with basement waterproofing problems.”
“I would like to share my experience of waterproofing my basement with this company. The technician located the problem spot right-away using appropriate tools, and provide me with recommendations and estimate. I liked that the quote had all steps and materials written. I also liked that the price was reasonable. The basement waterproofing was done as per quote. Step by step i could see how the basement waterproofing layers were applied on the basement wall. The work was done on time despite that couple rains interrupted the process. Now it is two month past since I’ve got basement waterproofing done, the wall is as dry as bone. Now i can start basement renovation without any future moisture concerns. Thank you Strong Basements for this experience. I, without doubts, wold recommend this company to anyone.”
