Crawlspace Dehumidifier

Removing moisture to eliminate mold and mildew

Keeping Your Air Dry

Moisture filled air in your crawlspace can quickly lead to mold and mildew growth, wood rot, musty odors, insect infestations, and health issues (in the form of allergens). A crawlspace dehumidifier’s job is to strip the moisture out of the air and to do it as efficiently and effectively as possible, thereby eliminating mold and mildew. At ’58 Foundations, our professionals are experts at crawlspace dehumidifier installation and are ready to help.

Humid Air Can Wreak Havoc

Your crawlspace is an important part of your home. It is a space that offers builders an area for plumbing, wiring, ductwork, and heating or cooling equipment. However, historically crawlspaces with vents open to the outside air and open dirt floors are notorious for creating a humid environment that is the perfect breeding ground for mold. You house and family can suffer from this situation. When mold grows on your floor joists, mold spores are carried up into your house and anyone with allergies is affected. In addition, moisture filled air leads to wood rot which in turn weakens floor joists and floorboards. Warm air is rising from your crawlspace accounts for over 50% of your home’s air composition, when that air is damp, your HVAC works overtime to compensate – and you pay more in energy costs.

What does a dehumidifier do?

A crawlspace fan, or more properly, a crawlspace dehumidifier works to keep the air in your crawlspace at a constant, low relative humidity level that does not promote mold growth. Mold grows at 60% relative humidity, so any dehumidification system must be set to keep the humidity below that level.

A Dehumidifier Cannot Work Alone

For the crawlspace dehumidifier to work successfully, it must be used in concert with an encapsulation of the entire crawlspace. A crawlspace dehumidifier will not be able to accomplish its job if the source of the humidity is not properly addressed.

Exterior air and an open dirt floor will always be significant sources of moist air. As an example, if it rains heavily outside and your crawlspace dirt floor is at approximately the height of the lawn outside, it can get just as wet inside as out.

Sealing the exterior vents and encapsulating the entire dirt floor with a 20-ml, class A poly-woven vapor barrier, provides the crawlspace dehumidifier an environment in which it can excel. In fact, today’s building codes no longer allow a contractor to put a dehumidifier into a crawlspace and just seal the vents – it must now be fully encapsulated.
