Waterproofing Contractors

Things to Remember:


  • Qualifications: The National Association of Waterproofing and Structural Repair Contractors (NAWRC) web site offers a list of certified contractors.

    Potential contractors should perform an inspection of your basement and water problem. They should provide you with a detailed explanation of the problem and what they propose to do to resolve it, in writing, including a warranty.

    Before Hiring a Contractor: Clean and inspect gutters for any leakage or damage. Inspect your drain slope: water should drain away from the house at least 48 inches to prevent foundation damage from standing water. Inspect drain pipes for leakage. If they are broken or leaky, call a plumber right away.

    Test your basement walls for seepage. Take a 12-inch piece of aluminum foil and attach it to the moist wall. Wait a few days, then check it. If there is water on the outside of the foil, it is condensation. If there is water on the inside, it's seepage.

    Leakage caused by clogged gutters or cracks around basement windows or doors can be repaired without a waterproofing contractor.
