The 4 Steps to Conditioning Your Crawl Space

Repairing a damaged or dirt floor crawl space offers many benefits to the overall health and comfort of your home. There are 4 steps to completely eradicate the negative effects that the crawl space might be causing, including high humidity, musty odors, or floors that are too cold. 

Step 1: Fix Water Issues (Damage/Leakage)

Usually the first part of this step is to install a sump pump in the crawl space. To install a sump pump, our team digs a hole at the low spot of the crawl space. Any water leakage will naturally flow down to the low spot. With the sump pump installed, any water leakage will be pumped out of the crawl space instead of pooling and contributing to humidity levels and mold growth. 

Step 2: Get The Home Separated From The Earth

Once water leakage has been addressed, the next thing to do is deal with the effects of exposed earth. This can include water vapor, mold, and the intrusion of pests. Crawl space encapsulation is the way we accomplish this. We use CleanSpace, a 20 mil thick plastic liner. The CleanSpace is sealed to the upper part of the wall, around any obstructions, and at the seams. This fully waterproofs the crawl space, and actually has antimicrobial properties too!

Step 3: Seal The Crawl Space From Outside Air

Now that the crawl space will no longer have water leakage issues, it's time to address another source of moisture: air vents. Some crawl spaces have vents that are directly open to the outside. On hot summer days, this means excessively humid air is able to enter the crawl space. This is done by sealing the vents with covers or an access door if needed. 

Step 4: Dehumdify

The final step to ensuring that a crawl space will stay dry and fully conditioned is to install a dehumidifier. A dehumidifier eliminates condensation in the air that could contribute to mold growth or water damage. 

With a completely dry crawl space, a home now has additional space for storage. Most importantly, the energy efficiency, health, and comfort of the home are permanently improved.
