"Paul Swann evaluated our foundation problem and referred us to an engineer who provided a detailed repair plan. Unfortunately, the nature and scope of the proposed repair plan was outside the parameters of what Northern Basement System's themselves could provide. We appreciated their honesty and have been looking for a contractor to take on the project."

"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan.

"He does a superb work. Everything pretty on my house was done by him."

"The work itself, the actual basement waterproofing appears to be working but our flood season hasn't come yet so, I'm reserving judgement. But, the way the work was done was a problem and the initial way that they got with the problem wasn't satisfactory. Eventually, months after work I did get some resolution but is wasn't a smooth transaction. We moved some of the finished portions of the basement to do their work and the way that that was handled was very sloppy and rushed, and very expensive to repair. And then, when the initial point of having somebody come and look at all my questions, it was not the owner, it was his foreman and it was not dealt within a professional manner. After 2 contacts, tried to explain what the problems were and has offered that they have an annual service to make sure that everything is working and there's a fee for that, though he offered 2 years of that with no cost, so that was a nice gesture. He tried to make up for the problems but like I said, there were problems."

"Diego is approachable and responsive. Very co-operative. Pricing was reasonable. The men finished the job on the day promised within the time suggested. They kept the workplace clean. Tested the grate sump and pump. Good attention to detail was maintained (e.g. they didn't just dig up my turf to bury the pipe, they had taken sections of turf out and then replaced them back so that the yard doesn't look bad). I will know next spring how good the sump/pump perform. I will use Diego & his team again and I strongly recommend him."
