How to Dry Out a Crawlspace

Having a clean and dry crawlspace is the backbone of having a healthy home. A damp crawlspace can act as a catalyst for health problems such as ear, nose and throat congestion and irritation or lung illnesses or infections. Having a wet, moldy crawlspace can undermine the solidity of your home: vermin are living beneath the floors, wooden floors are becoming warped, and a foul, musty smell pervades. You can, however, take steps to dry out your crawlspace yourself.

Instructions

- 1
  Determine where the moisture is coming from and take steps to prevent it. You may have a leaky roof, crack in the foundation or runoff from rain that is not directed away from the house. Find the problem and repair it calling in professionals as necessary.
- 2
  Remove all debris from the crawlspace, such as cardboard boxes and especially fiber-glass insulation as these things encourage mold growth and vermin habitation.
- 3
  Lay a moisture barrier on the clean floor and extend it upwards to the walls, but not covering any windowsills or frames.
- 4
  Install a dehumidification system within the crawlspace. Set the dehumidifier at 45% RH or lower as that will give the crawlspace an all-around balanced level of decreased humidity. It will also give the room some heat which will help it dry out.
