The new way to kill mold and keep it from coming back.
Serving Central NJ, Middletown, Woodbridge, Toms River
When I arrived at the home, before I even conducted my initial inspection, I advised the customer that adding more vents is NOT the answer. With a confused look, the client allowed me to explain myself in more detail. There is a common misconception (not only among homeowners, but even builders) that crawl spaces need venting in order to expel the hot, humid air. In fact, vented crawl spaces do the exact opposite. Building scientists now understand the stack effect in homes where rising warm air leaks out near the top of the house that, in turn, causes hot humid outside air to be drawn in around the foundation to the crawl space. In short, vented crawl spaces actually exacerbate humidity problems -- crawl space vents vents allow huge volumes of outside, unconditioned humid air to enter the crawl space area. Over time, this causes condensation problems and, ultimately, mold growth. I explained to the homeowner that the proper solution to reduce crawl space humidity levels is encapsulation, which, in part, entails sealing the existing vents as well as installing an effective dehumidification system.
Getting a hydrometer will help see how humid the area is.
This crawl space was so humid, condensation was everywhere.
After my initial conversation with the homeowner, I journeyed down below into the crawl space to determine the extent of the problems. Unfortunately, it was too late to prevent mold growth for this client. My inspection revealed high humidity levels, condensation throughout, extremely high moisture content in the joists and subfloor, and the ultimate consequence of this water and moisture build-up: significant mold growth.
Fortunately, the homeowner contacted a company with extensive modern-day expertise in mold treatment. Our treatment plan will involve fogging the crawl space with an EPA-registered Anti-Microbial to kill the mold on contact, wet wiping all of the mold, and then fogging a patented moisture-sensitive polymer sealant that will protect all of the mold-treated areas against future mold growth. Finally, to prevent mold from returning, we will seal the existing vents and install a SaniDry Sedona dehumidifier. These commercial-grade dehumidifiers have the horsepower to effectively condition the space and keep the humidity levels under 55% RH 24/7 throughout the year so that mold can't take hold. These machines are maintenance-free, empty into a sump pump or drainage system, and work automatically with a built-in hygrometer.
The client originally contacted Mold Solutions by Cowleys, which handles a variety of crawl space repairs and improvements, to, in his words, "install more vents," in his crawl space. Our Mold Solutions team will be starting shortly to convert this crawl space into a clean, dry, mold-free space that will rid the home of musty mold odors and improve the home's indoor air quality.
I was sent out to a home in Morganville, NJ, to conduct a crawl space inspection for a homeowner who found himself with crawls space mold growth. Crawl space mold is an all- too-common occurrence caused by chronically high indoor humidity levels that often build up in below-grade enclosed spaces with a damp dirt floor.
