Basements and crawlspaces are areas where moisture and mold growth are the most common. With all the products and systems on the market, how do you know what will work best for your basement or crawlspace? Protect against moisture by waterproofing your basement or crawlspace!

Costs of Waterproofing Your Basement or Crawlspace

  • Identify the Moisture Source: Identify the moisture source that is making its way into your home’s basement/crawlspace. Clogged or misdirected gutters and downspouts is the most common reason for basement moisture problems. Replacing and redirecting a gutter can cost up to $300. Foundation cracks are one of the most costly problems to fix. This type of repair requires a professional, and can range anywhere from $500-$15,000.
  • Crawlspace Ventilation: Crawl spaces commonly have higher relative humidity (RH) which is conducive to hidden mold growth, particularly if the crawl space has a bare earth floor. The soil will absorb and lock in moisture. Excess moisture/dampness can often be the result of poor ventilation. If heating or air conditioning is unavailable in the basement, then the installation of a dehumidifying unit can be a simple fix that costs about $250. If the water pipes require insulation, then the repair costs are $50-$100.
  • Property and Structure: Go outside and inspect the exterior walls for moisture problems. Make sure the ground is sloped away from the foundation walls. Check the downspouts, if they’re clogged, this could be creating and bringing moisture into the basement. Polyurethane sheeting is great for keeping moisture from seeping in. Consider insulation that’s completely enclosed in a vapor barrier. It is easy to work with since you don’t have to deal with itchy insulation fibers.

Waterproofing Your Basement or Crawlspace: Top 3 Tips

  • Installing French drains around your foundation will divert the water away from your home. A French drain is a trench covered with gravel containing a perforated pipe that redirects surface and groundwater away from an area. They are typically used to prevent ground water from damaging your foundation.
  • A sump pump is a small pump located in the lowest part of a basement or crawlspace. It is installed in a ‘sump pit’. Water flows into the sump pit through drains and/or natural water migration. The sump pump’s job is to pump the water out of the pit and away from the home so the basement or crawlspace stays dry.
  • Create a slope away from the outside foundation of your home. Add dirt next to the outside basement wall so that it slopes down two inches for every foot. Create a gentle slope away from your home’s foundation. This will prevent water from pooling.
