A selection of 534 homeowner reviews:
“We had a very positive experience with BQ. They were very efficient, and they knew what they were doing. They did it in a very timely manner. They put in a drainage system, re-cemented our entire bathroom floor, and braced my first floor with some columns. We were very happy with the experience—A.”
“They installed a sump pump and dehumidifiers, and they put in stands to help support the foundation. They were just very efficient. The sales process was very good, and I really liked the people that did it. It was very straightforward, and they did the work quickly. It was all very efficient. They're an A+.”
“BQ Basement Systems did some foundation repair work in my basement. They successfully repaired my foundation, and they did an exceptional job of cleaning up their work area when the work was completed. I'd give them an A.”
“We've had two things done. I've had some of the cement levelling done by them and I had a dehumidifier installed. I've got nothing but great feedback for them. I would say A+.”
“They were a great company. They waterproofed the basement, installed bright wall on the walls, and redid the ceiling in the basement. I'd give them an A+.”
“They did a complete basement—they went around the edge, put the stone in and a new pump and all that stuff. I would say A.”
“No problems.”
“I had no problem with them at all. They're good. They installed a basement, support columns for my main beam in the bottom of the house. We'll give them an A. I haven't had to call them back to need them for their customer service, so that's an unknown. I think I would recommend them.”
“They solved a problem that we had been having for a while and they were pretty quick with it and things just went smoothly. There were no problems. The workers were courteous and efficient and all that good stuff. It was a year ago. It seemed like it was a pretty good experience all around. I'd give them an A.”
“They were prompt and did the job. Jack system. I'd give them an A.”
