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.”
“They waterproofed one side of the basement and other areas, little treatment there. I would give them an A+. I didn't have any problems.”
“Everything was great. They put in a drain system in my basement. I got a sump pump. I got a backup battery and I got a dehumidifier installed down in the basement of my house. We were having some flooding issues and haven't had any since then. I'd give them an A+. I've had no issues whatsoever since they finished last year. They came back a few weeks later afterward to do a little concrete work for us out front that was related to the basement issues. Because the weather was bad when they were installing everything—it was a little snowy out and a little too wet to do concrete work. They were very good about following up and getting something scheduled a couple of weeks after that. Once the weather cleared up. I'd recommend them to anyone who I knew who was looking to get any sort of basement work done. Waterproofing, anything like that.”
“So far we don't have any problems. I didn't want any water in my basement and I don't have any water in my basement. They put in a French drain. I would say they were A+. I would recommend them.”
“They repaired the walls in the basement to protect from any water damage. What made it positive: the phone conversations I had with them from the beginning to the end, their follow-up, and the quality of works, and the professionalism of the men that were out there doing the work. Always communicated. Very important. I'd give them an A+. Definitely use them again.”
“They put in a sump pump and they put a paper barrier on the walls. They just did a nice job. Nothing memorable about the customer service or workers. I'd give them an A+.”
“Very, very informational. Answered all my questions and they were very quick and efficient about the project. They put in a drain around my basement. I'd give them an A+.”
“They did the basement—replaced floor and perimeter waterproof, perimeter drain. Concrete work was involved. They got her done and it was a process. They were pretty thorough, so it was positive. It was pretty cold outside and these guys just showed up, hit it hard, and it was good. I would give them an A.”
“They put in a triple safe sump pump system in my basement. I'd give them an A.”
“They were very friendly and reliable. They basically put in a drain system and sump pump in our basement. They were an A. Everything went well. They were good.”
“They were great. They waterproofed a small section of the basement for me. There was nothing in particular that stood out. I'd give them an A.”
“They did a good job. They put a sump pump in, a new sump pump. They were good.”
“They seem to be pretty good. They just provided maintenance and connection with a basement waterproofing system that the prior owner of my house had had installed. Not really a slight issue in the service. Give them an A.”
“We had French drains put in and a sump pump and a dehumidifier. It was OK. I had no complaints and I would recommend them.”
“They installed a brand new sump pump system along with a French drain, I guess you would call it. I'd give them an A.”
“So far, so good. They put that base around the cellar for water security and all that stuff. I would say an A. So far, everything is so good. I've had no problems. I would recommend them, absolutely.”
“Everything was fine. I had a listing and I needed that work done to sell it. They did the French drain around there, so basement water was coming into the wall drained into that and out through a sump pump. I'd give them an A. I'd recommend them.”
“I had a positive experience on the whole. Nothing that I liked about them or that stood out. They waterproofed my basement. I had no complaints and I would recommend them.”

“It was very positive. It was waterproofing. I didn't dislike anything. They were quick. They were clean. They were efficient. I'd give them an A.”
“They encapsulated a crawlspace for us. The workers did a very good job. I would say an A.”
“They were doing a crawlspace. They were good. Nothing in particular I liked or disliked about them. I'd give them an A. I would recommend them.”
“They did waterproofing of our basement. Nothing that we disliked. They were very good. I would give them an A.”
“They did a basement waterproofing system. Everyone I dealt with was very professional, very upfront. They did what they said they were going to do. They did it in a timely manner and I was happy with the result. The foreman was very good with communication. He gave me his cellphone number and called before they got there. He also called to follow-up after they left, so communication was very good. I'd give them an A.”
“They installed a new sump pump. They were just professional, clean, quick, and explained everything. They were just very pleasant. It was too long ago. I'd give them an A.”
“They did a crawlspace. They waterproofed the crawlspace and put in a clean slate system. Everything was positive from the bottom to the top. The workers were professional, easy to deal with, and knowledgeable. Outstanding customer service. I'd give them an A.”
“They did a crawlspace. They put a liner in a sump pump in a crawlspace. The guys were very thorough, very polite, neat, and orderly. I'd give them an A.”
“They did our basement. They did waterproofing. They just explained everything really well. They were very courteous. They were on time. They did a very good job. I'd give them an A. I am very likely to recommend them.”
“We just had a dehumidifier installed in our basement. It's been working well. I guess reassurance of our basement not having too many issues and we had mold, so just reassurance and they made it very quick and easy to get it installed. According to that time that was the main idea for us. I liked their knowledge of the product. A is good. It's pretty good.”
“They put some type of dryer or something down there. Waterproofing system. They were easy to deal with. They showed up on time for the quote. They showed up on time for the installation. They cleaned up after themselves. They were very good. It's all very positive. I'd give them an A.”
“They put a dehumidifier in our basement. They said what they were going to do and they did it in a timely fashion and it worked. I can't remember too much. I wasn't home that day; my husband was, but I believe he thought they were competent men. That's all I can say. They did what they were supposed to do in a timely fashion. I'd give them an A.”
“So far, so good. I don't remember.”
“They waterproofed in a basement in a house that I had for sale. They did it in a timeframe they said they were going to do it for the price that they quoted. I was not there. It was a vacant property I had as a listing and it was for sale and we had to have it done to meet FAJ requirements. I'd give them an A. I'd recommend them. I have them in my file for future reference.”
“They waterproofed my basement. They just showed up on time. They were very clean. The workman did all the things they said they were going to do for the price they said they were going to do it for. The workers were just very pleasant and very clean. Very helpful. I would give them an A.”
“They have done work for me on several occasions. They did a good job. They did basement waterproofing work. They did the work that they were supposed to do and the quality was OK. The workers were courteous and efficient. Nothing remarkable from the customer service experience. Their customer service was acceptable. Everything was acceptable. I am likely to recommend them.”
“I love my basement. The guys did a wonderful job, and they were wonderful. I just love it. It's light, beautiful, and dry. It's an old house, and the brick walls downstairs had been covered over with parget that was crumbling. They were able to repoint the bricks, cement them over, lower the floor a foot, stop the back wall from leaking, and put in a new staircase because the old one didn't go all the way down once they lowered the floor. I was thinking that when I do get around to the cement part of my backyard, I'll call them and ask them to do it. I'd give them an A+.”
“They gave me suggestions to get water out of my basement and didn't try to sell me things that I didn't need or that were more expensive. They actually came back and fixed it because I wasn't completely satisfied with it at first. They lifted the slab. It was sinking into the ground, so they used the filler to raise it up and stop the water from going into my basement. The first time, it wasn't raised quite high enough; they raised it a little bit more the second time they came out, and it's been perfect. I haven't been getting any water in my basement. They saved me thousands of dollars in concrete. I'd give them an A.”
“They are honest and reliable. I've gotten dehumidifiers and a sump pump from them, and they work well. They are right on top of maintenance, and they call to remind me to schedule it. They are very good—top-notch, I would say. I would highly recommend them. They deserve an A.”
“They've achieved the goal, so far. The one challenge was that initially, the motor on the system wasn't working correctly, and we thought it was having trouble managing the system. As soon as we called them, they said, 'Oh, no, that shouldn't happen. We'll be right out.' They fixed it no charge, and it was great. They put a perimeter drain around a whole basement that had originally had a water trough running around it. They closed it up and dropped plastic barriers on two of the four walls to dry and maintain the basement for us. We'd previously been having terrible flooding problems, and we have not since they did that. I would recommend them. The one challenge was that, of course, the electricity bill is more expensive because we have to run the dehumidifier and all that, but we don't have flooding in the basement. It's so much dryer, and so it's so much better for the house. The only other challenge we had was when there was a major storm that hit,and they had so many people calling them at the same time. It was going to be 11:30 or 12:00 when they finally got to our place, and I had a renter in there. I didn't feel I could ask the renter to accommodate that schedule, so they ended up not coming. That was the only problem we've really we've had with them; they were just on such overload that they didn't respond. I would love to give them an A+, but honestly, they get maybe an A-.”
“I've invested a lot of money with them throughout the years, and we like the professionalism and the quality of the work. I have a dry basement. They put a complete new French drain in our basement and a new dehumidifier, and they do a yearly service call. They're very reputable, and I would highly recommend them—A+.”
“They were very professional and very quick. They put three pumps down in the basement; they did waterproofing. They were excellent. They deserve an A+.”
“They did the follow-up testing to make sure the sump pump was working. They come out each year to do that. When we first had a water problem, we checked some local sources. We thought their prices were high, so we went further and started checking other resources. They tested things, did an estimate for us, and told us what they would do, how they would do it, and so on. We felt good about everything they told us, and that's how we ended up deciding to go with them. I would say they deserve an A because we've been totally satisfied with them.”
“BQ did an excellent job in solving my problem. It was waterproofing in the basement. There was a slight problem, but they fixed that. I'm going to give them an A.”
“It was a great experience, and they did a great job. Their efficiency stood out. I think I've used them for multiple things. We did a French drain and a sump pump, and we have a ladder to the basement—stuff like that. They were highly recommended. They're excellent.”
“They did a good, clean job, and they did it quickly—in one day. They did a nice job. They put a channel around the basement. I'd say they deserve an A+.”
“It was positive. The work was good; I have no complaints. Everything was good. It was waterproofing. They came out and explained the product pretty well. They had good pricing, and they were knowledgeable it seemed. I'd grade them as an A or an A+.”
“I thought they were very professional. They were on time, they called to follow up, and they sent out good reminders, so overall, it was a good experience. It was waterproofing. I liked the timeliness of their returned phone calls and the timeliness with which they came out to do an estimate—they were just very quick. I would give them an A+.”
“They're very nice. They were on schedule, and they were in and out in a couple of days. They did my crawl space, and it was a very tight squeeze. They did very good work. They've also been very responsive to some troubles that we've had. They put in a vapor barrier and installed a couple of floor jacks and a dehumidifier. They lifted the floor up a little bit, and they're supporting it with a couple of jacks. I would definitely recommend them. They get an A+.”
“They came in, did the work, and got out, and it works. They waterproofed the basement. I didn't have issues or have to call them back for anything. I'd give them an A.”
“I thought they were trustworthy, and the work they did actually worked—it was effective. I felt like they had good customer service, and they were ethical and reliable. I would recommend them. They deserve an A grade.”
“We had their basement waterproofing system in our old house, and it seemed to work well. We didn't have any issues. They were clean and on time—all those good things. They put in a basement waterproofing system and a new sump pump. We had the whole basement gutted, and they dug around. We had a French drain put in as part of their system. Overall, I thought they did a good job. I had a few people that gave me estimates, and we went with BQ Basement Systems because they seemed to be professional. I don't have anything negative to say about them. I think they deserve an A grade.”
“They were responsive and clean, and they did a nice job at our house. They did it in the time that they said they were going to do it in, so everything went very smoothly. They put a sump pump in our basement. This work was done quite a while ago, and they come out annually to do a checkup on it. I would recommend them, and I'd give them an A.”
“It was easy to get a quote, they did the work, and it was great. They did some repairs in the basement—it was water repair. The customer service was fine. They came when they said they would, they did the job, and I didn't have to call them back for issues. If I knew someone who had the same problem I did, I'd recommend BQ. They're an A.”
“They did good work. They did basement waterproofing. The customer service was fine. I would refer them, and I'd rate them as an A.”
“They did good work, and they were on time. They were good guys. The manager worked to come up with as good of a plan as we could within a budget, and they followed through. They waterproofed and kind of finished the basement. They deserve an A.”
“BQ did waterproofing. They were recommended to me, and I'll give them an A.”
“BQ's service was fine. They did waterproofing, and they did an A-worthy job.”
“BQ Basement Systems did waterproofing. There's no problem that I can see right now, so they're probably an A.”
“We had work done about two years ago; then, they came back last year, and they'll come back this year. They put a system in the basement to divert water away from the house. Their customer service was fine. I would say they earned an A.”
“They were on time, and everything was good. They were great. They did some waterproofing and fixed some drainage issues. I think it was a good quote, and they just seemed reliable. The customer service was very good. I'd give them an A.”
“We had a system put in, and they were very professional. They did exactly what they said they were going to do, so there were no surprises. It was a combination of a sump pump and a dehumidifier. I had done some research, and I came across them. I'd give them an A rating.”
“They were very efficient, quick, and straightforward. I can't say anything but good things about them. It was waterproofing. They were local. They get an A in my book.”
“Everything was excellent. They were repairing work that another waterproofing company did. I found out about them because they are local, and I would recommend them highly. They earned an A.”
“When they came out, they were very thorough with the estimate, and they were also very thorough in detailing everything that was going to be done with the basement. We had a problem after they put in the system, and they were very responsive in coming out. They corrected the problem, and they made sure that we were completely satisfied before they would leave us alone. They had to put in a sump pump. We looked into some of their references, and they had a good reputation, so we went with them. I would give them an A—they were excellent.”
“They insulated our crawl space. It's going to help against the water, and they put a new door on our crawl space. They came on time, they were professional, and they were thorough with what they were doing. We liked them and what they offered, so we hired them right away. They're an A+ company.”
“We had some waterproofing and a French drain done. They put in a moisture barrier and a thermal barrier, and they installed a sump pump as well. I liked the workers; they were timely and professional, and they got everything done on time. There were no surprises—A+.”
“They do exactly what they say they are going to do, and they stand behind what they do. They sealed my foundation walls for water. I had tried four different companies; they were my fifth try, and they worked. I'd give them an A+.”
“We had a flood in our basement, so they did the reconstruction and put in a new drain system and pump. They had good customer service, and they were timely and neat. I'd give them an A rating.”
“BQ put in a sump pump that I'm very satisfied with. They seemed to take an interest in my project, more so than normal. I went through three or four different people, and I chose them because I liked what they said in person. They're an A.”
“They are good, and they did a good job for us. They did waterproofing, and it was good. I would recommend them, and I'd give them an A.”
“They worked in our basement when we had water. They did a complete perimeter excavation. Initially, we found some things that needed completed again, and they came back and stood by their work. Many years ago, Brian Quinn was a contractor that used to work on basements before he became BQ Basement Systems. I used him then, so I called him again. I would give them an A.”
