Crawlspace Supply International

CSI (a subsidiary of RCI) was established in 2006 to provide specialized Crawlspace Moisture Management/Encapsulation products.

Research in the "Science" of crawlspaces has revealed that the traditional method of venting the area to reduce moisture and mold growth was actually the very cause of much of the moisture and mold.

Encapsulation (or Closing) of the crawlspace using plastic vapor retarders and other components has emerged as the most effective method of eliminating this moisture.

With over 26 million homes in the U.S. built on crawlspaces and roughly 250,000 being built each year, the need for contractors to provide this service is on the rise. Several large franchises, with locations all over the country, have emerged due to the calling for the service. They offer a viable service to their clients by eliminating the moisture that causes wood rot, mold growth, and a breeding ground for wood destroying insects. In addition, homeowners benefit from decreased energy bills* and increased air quality**.

CSI's goal is to provide independent contractors the products needed for the encapsulation application that will adapt these vented crawlspaces into clean, efficient, dry, safe areas of the home. To learn more about the process, please see below or call Dave Weaver at 1-800-523-2084.

CSI is a wholsaler/distributer and strictly sells to contractors who perform this nature of work. At this time, we do not sell to the general public.

For more information on Closed Crawlspaces, please follow the link below for the studies and research of ADVANCED ENERGY www.crawlspaces.org
This link will lead you to their page dedicated to Closed Crawlspaces, which includes comprehensive guides to perform the work, useful articles published in support of the process, videos of actual crawlspaces in need of and with the process applied, and other extremely effective research data collected by their scientists. CSI apprecaites all their work and for providing the specifics of how the process works and it's benefits.

*Crawlspace Encapsulation can decrease energy bills by reducing the amount of the home that is "conditioned". When crawlspaces are vented (have outside air moving directly in) in the summer months, it causes the air conditioning to work harder to keep the living space cool, (and the opposite occurs in the winter). An energy discount is the result.

**Crawlspace Encapsulation reduces the amount of allergens in the living space of a home by eliminating the damp, often dirty, moldy environment that usually exists in vented crawlspaces. By eliminating those conditions, the air in the home is cleaner and healthier. (Research has proven that people with respiratory issues can benefit greatly from the application)
