Crawlspace Encapsulation Services

crawlspace encapsulationMany crawlspaces are humid, damp and musty and can be filled with mold and pests. These traditionally vented crawlspaces create unhealthy and dirty air that can contain mold spores, dust mites, particulate fiberglass insulation and other allergens. The air can rise through your home and mix with the air inside your home through hidden air leaks that exist in the walls, floors and ducts of your home. These air infiltration points are the results of unsealed plumbing, electrical and HVA penetrations in the framing. Humid outside air can seep into your crawlspace through your foundation wall. The air condenses on cold surfaces like air conditioning ducts and equipment, plumbing, floor joists and insulation. The wet wood will eventually rot, and will attract termites and other wood destroying organisms.

If have an unsealed crawlspace and your HVAC equipment is store there, it is dealing with the unconditioned outside air. This makes the system work harder to overcome the hot temperatures that surround the ductwork and furnace/air handler. Old vapor barriers can become ineffective because they are bunched or folded. They may have been punctured or the seams may be poorly sealed or untaped, which means that your crawlspace floor is not complete covered. Replacing old vapor barriers or encapsulating your crawlspace can keep your home in good repair and keep your family safe from the complications of unclean air.

To fully ensure the indoor air quality, structural durability, optimal comfort of your home and energy efficiency, your crawlspace must be dry, sealed and conditioned. Crawlspaces should not be vented to the exterior. In the past exterior ventilation was the preferred method, but research and practice showed that it was inefficient and actually harmful to homes. A fully encapsulated crawlspace is the best solution for all the issues. A Full Crawlspace Encapsulation is accepted by the Building Performance Industry as the most cost-efficient and effective investment for moisture and humidity control, mildew, mold and fungi prevention, interior comfort problems and indoor air quality, energy efficiency and pest exclusion.
