Crawl Space Inspections

Environmental Solutions Group provides crawl space inspections and recurring crawl space checkups performed by investigators who are certified IEPs (Indoor Environmental Professionals).  

Most crawl spaces are dark with exposed duct work, bare dirt and little room to move around.  Homeowners simply don’t want to spend time under their home, making this one of the most frequently neglected areas. But did you know that up to 40% of the air in your home comes from your crawl space? A drawing of the stack effect. It shows how the crawl space can affect the air quality of the entire home.

Water damage and mold growth can go unnoticed in your crawl space. Contaminants can spread to the interior of your home, affect your health, and cause damage that costs thousands of dollars to repair. That’s why preventative maintenance is important with crawl spaces.

Whether you suspect an issue with your crawl space or just want to have an expert check in on it, we can help. With a short visit, our experienced, knowledgeable investigators can inspect your crawl space and identify any  issues before they become a larger problem. 

A crawl space inspection consists of an investigator:

  • Exploring the entire underside of the house and documenting the conditions with photos
  • Collecting wood moisture measurements from joists and the sub-floor
  • Checking the vapor barrier for tears or gaps that could allow moisture to evaporate A crawl space. Crawl spaces are often overlooked by homeowners. on the floor system
  • Noting any strong musty odor (A crawl space should smell earthy, not musty)
  • Observing any debris that should be cleaned up, such as old pipes, insulation, or duct work lying on the floor
  • Detecting the level of air movement through the crawl space. (In larger crawl spaces, we often find a dead zone near the center, which can be home to more than typical amount of fungal growth.)
  • Collecting a surface sample for lab analysis (if deemed necessary) to determine what type of mold, if any, is present

After the assessment, ESG will provide a report that includes a list of observations and recommendations. 

If you’re interested in yearly inspections, the spring and summer months are best; the air conditioning system will most likely be in use, and mold is most active in the warm weather. (It’s important to note that some mold on the floor system of your home is to be expected and may be defined as a ‘normal fungal ecology.’) Contact us to learn more or set up an inspection!
