PERSPECTIVES Our View of Basement Seepage Given the right condition, any basement can leak. No one can predict if a basement will leak in the future, and in many cases, it's not even possible to tell if a basement has leaked in the past. Basement seepage is the result of water concentration along an exterior foundation wall - which then seeks an entry through foundation cracks. It's important to eliminate the cause, not just seal the entry point. Over time, neglected moisture intrusion problems can create significant structural and indoor air quality problems. However, the majority of wet basement problems can be eliminated, or at least reduced to a tolerable level, by improvements to exterior grading and proper performance of gutters and downspouts. The most common cause of wet basements is poor surface and roof drainage. In fact, our experience indicates the vast majority of wet basements are simply caused by surface rain water from improper drainage or slope. Keep in mind, a 1,000 square foot home with an attached garage will have over 1,100 gallons run from it in one-inch of rain. That's a tremendous amount of water. Imagine a downpour on a home with blocked gutters. Conditions change, foundations move, gutters become blocked, landscape changes, and extended periods of drought or rain occur -- all of which can cause changes in the basement. Wet basements are a major concern -- but shouldn't necessarily kill a deal. While basement seepage is a critical issue, often simple remedies are available and are well within the scope of most homeowners/buyers. Not only do our inspectors fully examine the basement and explore any potential defects , we present this information in a manner that helps our clients k eep the issue in perspective . Homeowner suggestions include: With every inspection, we provide 12 months of our Extended Advice SM program so your clients always have a direct source for information about managing their new homes. For basement seepage, we recommend the following before seeking a specialized contractor: w Make sure the land around the house slopes in the right direction.
