How Does Water Enter The Crawl Space?

So maybe you don’t do much crawling around in your crawl space. But that doesn’t mean you shouldn’t focus on keeping it clean and dry. Just like basements, crawl spaces are susceptible to water damage because they’re the lowest point in the home.

One cause of issues is surface water. Everything from undiverted rainwater to leaky systems can cause water issues in your crawl space. (Not to mention other probable causes like overflowing rain gutters and backups in the storm or sewer water systems.)

It may not be as obvious as large sources of water like rain or pipes, but one of the biggest culprits of water seepage is the moisture-filled earth that surrounds your crawl space. Regardless of the material that was used when building the structure--bricks, concrete, stone--it can be susceptible to seeping water when the ground puts pressure on the walls and forces moisture through tiny cracks and joints.

What Are The Risks?

Crawl spaces are often much smaller than full basements, but excess moisture even in those tight areas can create issues throughout the home. The main problem is that the damp, humid air from the crawl space is circulated upward, introducing mold, mildew, dust mites, and other potential air quality issues to every area of your home.

Common symptoms caused by mold and mildew:

  • Allergies
  • Worsening of asthma and other respiratory ailments
  • Nasal and sinus congestion or infection
  • Cough and sore throat
  • Breathing difficulties and wheezing
  • Skin and eye irritation

In addition to health risks, excess moisture in the crawl space can ruin irreplaceable items. If, like most people, you use your crawl space for storage, water can quickly destroy cherished heirlooms, photos, or other valuable items.

The Solution

Crawl space encapsulation is the process of sealing off the walls and/or floors to prevent water seepage from outside and to remove the risk of stale, humid air circulating throughout your home. Each case is different, but an experienced encapsulation specialist can help you decide on the best path for addressing the issues that are specific to your home. The sealing process essentially creates a water-tight seal in the crawl space, removing the chance for moisture to enter and cause issues.

Along with keeping water out of the crawl space, you can take steps to remove excess moisture by using an Aprilaire dehumidifier.
