We just recently purchased a home that had a few issues with water coming through certain spots. I received their number though my real estate agent and had the pleasure of working with Anatoliy K. He is professional and knowledgeable, and really takes the time to explain everything that you need to know. He always responded to any questions I had and answered them promptly. We waterproofed from the inside since we were gutting the basement, and replaced a bunch of pipes. We also installed a sump pump and backwater valve, which why not since you get a rebate for it. The labor done by the rest of the crew was completed on time. Everything was done neatly and I am extremely happy with the finished product! We've had no water issues since we've done the waterproofing. Couldn't be any happier with my services from these guys!! We highly recommend them if you are looking for a professional company that does what they say they do if not better.
