Mold Damage Linked to High Indoor Humidity
How high humidity can cause mold damage in your home
Residents of the Ark-La-Tex area experience long hot and humid summers. High levels of airborne moisture and warm temperatures indoors can contribute to the increased likelihood of mold growth in your home, even if you have air conditioning operating. Working with a reputable mold remediation company can help you pinpoint the reasons mold growth is an issue in your home as well as remediating the current growth.
Water is the fuel that accelerates mold damage in your home. Mold spores are very opportunistic, gaining enough moisture from small amounts of dampness or small collections of condensation to begin growth. Running an air conditioner is often recommended to reduce interior humidity below 60 percent, the level where mold can find a supportive environment even without spills, leaks, or flooding.
Ironically, AC units can provide the moisture if operating inefficiently or if the wrong size for the space cooled. An air conditioner too small for the area is one problem SERVPRO sees, but an overly powerful system also can fail to reduce the humidity enough to halt mold development.
Air conditioning provides a cooling feeling when it removes moisture from the air, usually by condensing the water vapor on refrigerated coils. If adjusted correctly and draining properly, the system works well and prevents the conditions conducive to mold growth. Sometimes a larger than necessary unit does not operate long enough to reduce the humidity below the “sweet spot” for mold growth. It pumps cold air into the rooms too quickly and then cycles off before the humidity reduces. Mold then grows on the damp surfaces, necessitating mold remediation by our SERVPRO crews.
Keeping AC condensers and coils clean and the drains free-flowing is also key to preventing interior mold growth during a hot summer. If the drain is plugged, it may overflow, depositing moisture on a wall or floor nearby. Mold finds wood and drywall perfect organic surfaces to call home. SERVPRO inspects for these moisture sources when we arrive to assess and plan for mold remediation. If the homeowner does not address these issues, chances are good that mold can return even after we complete a professional treatment.
SERVPRO of Texarkana is eager to help community residents understand why mold finds a home attractive. We design strategies to remove current colonies while also inhibiting future outbreaks. Call us at (903) 832-4400 to schedule an evaluation.
