Back in 2020, Laswon Home Services were called to address foul odors coming from the crawlspace of this Camden Wyoming, DE home. Our Energy Auditor went into the crawl space and found that it had only a thin layer of black plastic, which had been laid directly onto the dirt floor of the crawlspace. This plastic was not sealed to the edges of the walls, and, in fact, you could actually see the dirt around the edges of the plastic. Ground moisture was evaporating and traveling around, and even through the thin black plastic, ending up raising the relative humidity of the crawlspace air and then condensing on and being absorbed into the wood structures supporting the first floor. The evidence was clear to see: mold was growing all over the wooden floor joists.
Lawson Home Services removed the musty damp insulation, pulled out the ineffective black plastic and installed the Dr. Energy Saver CleanSpace™ Crawlspace Encapsulation System and a Sedona™ SaniDry Crawlspace Dehumidifier.
This homeowner made the wise decision to set up an annual maintenance schedule with Lawson Home Services. A technician now returns annually to perform a number of things, among them inspecting the CleanSpace liner and servicing the Sedona™ SaniDry dehumidifier, and makes sure everything continues to function as good as it did the day it was installed. This home passed the 2023 inspection with flying colors. We'll see them next year.
