How do I determine if I need a dehumidifier in my closed crawl space?

How do I determine if I need a dehumidifier in my closed crawl space?

Sep 12th 2016

Closed crawl spaces mean less worry about excess moisture and the problems it brings. Still, it is impossible to remove absolutely all moisture, all the time. In some climates and seasons it may be necessary to add a dehumidifier in your closed crawl space. When do you need a dehumidifier? It may be hard to know, particularly if you rarely enter your crawl space. These clues can help. There are several household signs that can point to the need for a dehumidifier in your closed crawl space. Here are just a few.

Your home has a musty smell

The culprit may be high moisture levels in your crawl space. Moisture in the area creates the perfect environment for the growth of mold and mildew. Dry the air to get rid of the smell. Placing a dehumidifier in your crawlspace will improve air quality, remove mold growth and prevent the growth of new mold.

You are experiencing allergies or asthma

The air in your crawl space does not stay there; it enters your living areas. Poor quality air increases the likelihood of allergens and mold. Some people develop asthma, allergic reactions or experience flu-like symptoms in response to the poor air rising from the crawl space.

Your HVAC system, duct work or other equipment is in the crawlspace

Condensation from water pipes, ductwork, or truss plates can create harmful moisture. A dehumidifier is a good option for drying the moisture that drips from the equipment as well as the moisture held in the crawlspace environment.

You notice damage to the structure of your home

Excessive crawl space moisture can cause structural damage to your home. Potential problems include:

  • Insect damage, including from termites
  • Wood rot
  • Buckling hardwood floors in the living area
  • Rust
  • Sagging insulation
  • Swelling of doors and windows
  • These problems should be addressed early, before extensive repairs are needed.
