Step 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.
Step 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.
Step 3
Lay a moisture barrier on the clean floor and extend it upwards to the walls, but not covering any windowsills or frames.
Step 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.
Things You Will Need - Garbage bags
- Gloves
- Moisture barrier
- Dehumidifier
Tip
- A moisture barrier is an enormous plastic sheet, often with anti-fungal properties that prevents moisture from entering a space from the outside. However, if the proper precautions are not taken in step 1, this measure will become ineffective.
