Your guide to qualified waterproofing contractors is your telephone book which can be accessed online providing you with address and telephone contact information. What you need to know is that waterproofing contractors are not your local plumber. When your basement walls are leaking, which can be seen if your walls are contaminated with a black mold looking growth that can't be washed off or even painted over, you should look for waterproofing contractors and not plumbers. Another sign of needing waterproofing contractors is if your backyard is constantly flooded or feels constantly soggy when walking on it. A plumber is not equipped to provide the waterproofing you need with digging trenches and laying in of new underground pipes to collect rain and downspout water and carry it to the street or to the city sewer. Calling a plumber for waterproofing will be a waste of money. A clogged kitchen sink is one problem, water seepage into your buildings basement foundation is another problem.
