Certified Waterproofing did an outstanding job for us at a very reasonable price. Our 104-year-old house with stone foundation leaked at the basement floor level following severe rainstorms. Other foundation repair companies had proposed grandiose schemes at exorbitant prices, not seeming to hear what we suspected was the cause and our desires for minimum disruption of home and landscaping. Certified was a breath of fresh air. I was impressed with the skills and professionalism of the management and technicians, all of whom were good listeners and respectful of our time and property. The job was completed in timely fashion, looks great, and the cleanup was exceptional.

They came out in June. Did not finish the job left a bunch of stuff in our yard. we have been calling them ever since to come out and every time they tell my husband someone will be out or call him and nothing. We got a bunch of rain and our basement has now gotten water in it. We called again today and were told the same thing. I would not recommend them at all.
