50% of the air you breathe in your home comes from your crawl space. Not only does mold effect your indoor air quality, and can affect your health, but it can cause structural damage to your home. Mold can promote wood rot on the joists of your home compromising its structural integrity. The high humidity and moisture that allow this mold to grow, also create an ideal environment for pests and insects. By not fixing this issue, it will only continue to get worse and become more costly to repair.
Properly encapsulating your crawl space with a dehumidifier and, if necessary, interior foundation drainage and sump pump will make the structure more durable. Sealing the crawl space keeps out moisture, by controlling relative humidity we are helping prevent mold from growing. Along with installing a dehumidifier, we can control relative humidity, by doing this, we can help ensure a clean, healthy, dry, and temperate crawl space. This results in better indoor air quality and a more comfortable home.
The CleanSpace 20 mil vapor barrier is a 7 ply, string reinforced, polyethylene liner with a built-in antimicrobial. As a result of its thickness it will stand the test of time against a normal crawl space wear and tear. It is durable enough for home owners to use their crawl space for storage without worry of tearing the liner and is sturdy enough for servicemen to crawl on it without puncturing or tearing the liner. The CleanSpace 20 mil vapor barrier is also backed by a 25-year transferable warranty.
The purpose of installing a dehumidifier is to maintain proper humidity levels, slow down or stop mildew/mold growth, and to aid in air filtration. Humidity levels should be no more than 60% in the crawl space. This is an ideal environment because mold requires temperatures of 70 degrees or warmer, 60% relative humidity or higher, and organic material to grow. Keeping the relative humidity below 60% helps prevent the mold/mildew from growing, The Drying Co. uses the SaniDry Sedona as a preferred product to achieve this.
The goal of interior foundation drainage is to manage any bulk water entry into the crawl space from either foundation wall penetrations or hydrostatic (ground water) pressure. Interior drainage usually consists of a French drain along the perimeter walls, fed to a sump pump and sent through a discharge line away from the hone 10-12 ft. from the foundation. Keep in mind that not every home needs interior foundation drainage, our Home Performance Advisors will do a thorough inspection your basement and/or crawl space to verify if drainage is necessary.
As a result of the environment created by a proper encapsulation with a dehumidifier, future treatment from pest control and moisture management companies is drastically diminished. Typically, the biggest point of contention stems from a “lack of visibility for inspection” even though a 3” viewing strip is left at the top of the foundation walls as well as the full 1.5” face of the wood sill plate. VA Building Code requires a 2” viewing strip and that the face of the sill plate is visible for pest companies to inspect, by providing visibility with a 3” viewing strip and the full 1.5” face of the wood sill plate, The Drying Co can exceed VA Building Code. The Drying Co. wants to work with termite and pest control companies in order to provide a dry, healthy, and durable crawl space environment. If a homeowner’s termite and pest control company refuse to work with a conditioned crawl space, The Drying Co. can provide references for companies that will.
When remediating mold, it is always recommended to remove the mold with an antimicrobial solution and a physical wipe down of the entire affected area. By just spraying the mold with an antimicrobial, a contact kill can be achieved, however a majority of the bulk material growth, though dead, will remain giving the appearance of active mold growth. This residual material will eventually dry and flake becoming airborne. This can enter your living space as 50% of the air you breathe in your home comes from the crawl space. This airborne mold, though dead, can still be harmful to your health as a respiratory irritant. Please keep in mind that everyone reacts differently to this.
It may impact your relationship with your current termite and moisture control company depending on their policies. There are, however, termite and moisture control companies, which The Drying Co. has developed relationships with, that will warrant structures with encapsulated crawl spaces. Typically, those companies want to inspect the crawl space prior to encapsulating in order to provide any pre-treatments necessary. Per Virginia Building Code, The Drying Co leaves a 3-inch viewing strip and the full 1.5-inch face of the sill plate visible. This provides termite and moisture control companies the visibility they need to perform their inspections.
