Crawl Space Mold Remediation

Depending on your geographic location, many homes have either a crawl space or a basement. Crawl spaces often maintain conditions that allow mold to thrive, leaving you with an unhealthy environment beneath your home that can affect air quality in the living space.

What is Crawl Space Mold?

Mold prefers to grow in a dark, dank place with plenty of moisture to feed off of. Even a small amount of water can lead to crawl space mold, particularly on the walls, the underside of the subfloor and the joists. In the right conditions, crawl space mold can create reservoirs of mold growth that allow it to spread throughout your home. This is bad news when it comes to maintaining good indoor air quality.

 

 

Signs You Might Have Crawl Space Mold

If you're not sure whether your home's crawl space suffers from mold growth, look for the following signs:

  • Poor indoor air quality causes heightened allergies and asthma symptoms while at home with no other apparent cause
  • A musty odor permeates the home, especially when the windows and doors are closed
  • Family members suffer from chronic headaches
  • Multiple plumbing pipes have broken or had other problems
  • Cables and home wiring have issues
  • Floorboards are buckled or warped

Causes of Crawl Space Mold

  • Foundation vents: Many crawl spaces feature vents that are supposed to prevent moisture problems, but recent research indicates that vents often cause more moisture buildup than they prevent. Some of these vents feature fan systems, which, again, are supposed to be helpful, but can actually cause more harm than good.
  • Humid weather: When vents or crawl space fan systems draw in air during humid or rainy weather, the crawl space becomes a breeding ground for mold. The moisture is drawn into the space, where organic materials in the form of dirt and wood encourage mold growth.

Reasons to Upgrade to a Closed Crawl Space

With the realization that vented crawl spaces aren't good for preventing mold growth, more and more crawl spaces today are built tightly closed. The goal is to completely enclose the crawl space and separate it from the exterior with a moisture barrier on the floor and liners that extend up the walls.

In addition to blocking moisture that causes crawl space mold, closed crawl spaces can help reduce your heating and cooling costs. This is good news when the utility bills arrive and it helps reduce waste as well, which is good for the environment.

If you suspect you have crawl space mold, it's important to have your home inspected for indoor air quality problems. The specialists at Rainbow International® can also remove the mold and prepare your home for an upgrade to a closed crawl space designed to prevent future problems.
