Wonderful service provided. We are very satisfied with our updated crawl space. Highly recommend this company. Jessica well organized all details in office with exceptional and professional follow up. David visited our home for quote inspection. He was delightfully pleasant and thoroughly explained the entire process. Amazing staff and work crew from start to finish.

This is a very professional company from the receptionist to the technicians. Found multiple sites in my foundation that needed to be waterproofed. They use a method that is used to repair leaks in major dams like the Hoover Dam! I was very impressed with this! They also test it after waterproofing to make sure it works. Awesome- I am very pleased!

I used Complete Basement Systems to install drains in my den, which is below grade, as well as in my crawl space, which they also waterproofed after Sandy. The installation went smoothly and their service was excellent. Never had a problem with the pumps and they are still going strong. I highly recommend them!
