A selection of 534 homeowner reviews:
“We had a very positive experience. They encapsulated the crawl space under our house. They were very efficient. They got the job done right away, and it's excellent quality. I'd give BQ Basement Systems an A+.”
“They were amazing. They waterproofed my basement. They did a sump pump, dehumidifier, and French drain. It was A+ work. I've recommended them since.”
“It was terrific. They're a really great company. I had a flood in my basement, and they put in a large dehumidifying system. It was just all very nice and clean with them. I would give them an A+. I haven't had any problems with it, and I've already recommended them.”
“BQ Basement Systems did a great job. I'm very happy. They did a sump pump. Their customer service was outstanding.”
“Waterproofing our basement. He was very thorough and not high pressure. He had a lot of information and was very clear and answered all of our questions. When we decided to go ahead with it, they were recommended to us and we decided to go ahead with it. The scheduling was very smooth and we had to change our appointment several times. They were very easy to work with and able to get it rescheduled to what wound up better even after we had to change it. Then it went as smoothly as they told me it would, so everything went very smoothly and the results have been terrific. It's everything we needed. I'd give them an A+. Very likely that I would recommend them.”
“They were very friendly, very organized and neat, and cleaned up afterward. It was a very positive experience. They put a sump pump in our basement. I'd give them an A+. Everything went really well. We already recommended them.”
“It was very much positive. Waterproofing. Professional, neat, clean, and it seemed to have worked. Zero complaints. Absolutely thrilled with everything. I'd give them an A+.”
“The gentleman who came out to the house to do the estimate and take care of all that—the foreman, I guess you could say, was just really good. He had no problems answering any questions and I had plenty of questions. He didn't show any kind of impatience toward me as well as the workers who did the work were also extremely nice and didn't have any issues. They encapsulated my crawlspace. I'd give them an A.”
“We had a laundry room in the basement in an apartment building and it was flooding with water every time it rained. They pretty much weather treated and stopped it from having water down there on a constant basis and so far, so good. We don't have water down there anymore. The workers were good. They were quick, on time, cleaned up after themselves, did an excellent job, and got done on a timely basis. I'd say they're an A.”
“They did a French drain. Everybody was professional, timely, respectful, and they did what they said they were going to do. They were very polite and respectful. They worked within the time they said they were going to and they were always there when they said they were going to. They called before, stayed within the timeline that was agreed upon and I appreciated that. It was excellent, so an A.”
