Toxic Mold

Thousands of homes each year, in the Southeast, are built with vented dirt crawlspaces and yet virtually all building science experts agree that vented dirt crawlspaces are a bad idea.

What is Crawlspace Encapsulation?

Crawlspace Encapsulation is an elaborate form of a permanent sealed thick vapor barrier that can have a sump pump underneath for drainage. They are so well sealed they keep out water, moisture, mold, toxins, soil gasses, radon, bugs, rodents, and other contaminants. If air ducts are present, the space actually becomes conditioned and saves approximately 15% on power bills. Encapsulation converts a unhealthy dirt crawlspace into a Healthy, Dry, Sealed Crawlspace.

Unvented Sealed Crawlspaces are the new Residential Code

From thermal, moisture, structural, occupant health, financial and operational standpoints, sealed crawlspace foundations perform better in my opinion than vented crawlspaces. Essentially all other building science experts around the country also hold this opinion.(Reference: Energy and Environment Building Association) - Craig Dewitt, PhD 

Customers say this is common sense

Heather, a PureAir Systems customer in Sandy Springs says that the outside air always smelled so much better than inside. She was also concerned about her house sitting on top of a dirt crawlspace. She continues “It’s really gross to think about all that moisture coming up through the floor, it can’t be healthy. It concerns me that I have been breathing all of that disgusting air. That is why I had PureAir Systems completely seal the crawlspace.”

Crawlspace Encapsulation Methods

PureAir Systems uses their exclusive 2 part adhesive system and permanent hangers to guarantee the liner seal to all foundation walls, piers, pipes, etc. Many others are not properly sealed allowing contaminants and moisture to come right into the crawlspace.

Importance of Crawlspace Mold Treatment

There are three types of mold groups; primary, secondary, and tertiary. As mold gets established, the more toxic ones often begin to set in. The wood floor allows air and toxic mold to move right into the house, but even worse all air conditioning ducts leak and blow soil gases and mold evenly throughout the house.

It is a mistake to encapsulate a crawlspace without treating any mold on wood structures of the floor, because it traps contaminants into the house. PureAir Systems uses the 25 year guaranteed mold treatment with Structure Guard to keep the air clean.

Crawlspace Encapsulation is the only real solution to the dirt crawlspace and could be the most important decision you ever made with home ownership.
