The crew that worked on my crawl space were very courteous and respectful. They made sure to clean up after the work was completed and I'm so happy with the outcome. Would highly recommend the company.

Complete Basement Systems did a great job. My driveway and sidewalk are in MUCH better shape. I felt they did a thorough job in diagnosing the sources of my concrete problems. The only reason I didnâ  t give them 5 stars is that they were unable to completely level one of my driveway slabs - close, but not quite.

I had to put the 51 linear ft of wall back together after complete basement systems cut out 11 inches from the floor to the bottom of the outlets. For the price that should be included. It took me 16 hours of work as I had to cut and fit 52 pieces of 2x4 individually as they were not cut straight and the same height when removed. Replace the 11 inches of drywall and then tape and texture and paint. That in itself was a lot of work to do.

With flooding in the basement, we felt like we were in crisis. Complete Basement Systems came in, developed a workable plan and were affordable. We were glad we selected them as our contractor.

Complete Basement Systems installed a Window Well Sump Pump for us. Although the weather was not cooperating, they went ahead and installed the Pump as intended and the Electrical was installed about a week later. Overall a top quality and professional job!

Placed a request for an estimate and Complete Basement Systems called within the hour, only one other contractor called but it was two days later. All my concrete issues were resolved as promised. Process was quick and well done. Crew was on time and cleaned up any mess that had incurred.

This was the only company who called me right away (and I called two others myself to see if they would offer an estimate) and this was the only company who knew what to do and was willing to take the job. Excellent all around, from the person who inspected the issue and provided an estimate to the technician who did the work. I highly recommend you consider this company if you have any problem with your basement

They tried to sell me on work I didnt need. When the guys came to do the work they didnt know what they were suppose to be doing. Even after I explained what they needed to do they did the wrong work and I had to have them re-do their work. All I needed, per a structural engineer, was to have 3 of 6 steel posts adjusted in my basement. Initially they adjusted 4, 3 that didnt need adjustment and 1 that did. Then when I asked them to fix their work they only adjusted one of the 2 I needed adjusted. I decided to buy the tools and adjust them my self. They charged ~$300/post to turn a screw.
