Most homeowners never see the problems plaguing their crawl spaces until it's too late. Moisture - whether from standing water, active leaks, or humidity and evaporation issues - is the unseen cause of disastrous mold, rot, and structural damage below a home.

Even when structural damages aren't accumulating in a problem crawlspace, mold, mildew, and other air quality impacting factors have a costly effect on the health and safety of everyone living above. Through a phenomenon called the stack effect, warm air rises and drags cooler air from the crawl space through vents and floorboards, bringing with it mold spores, dust, and bad air to circulate around the entire home.

HVAC systems that have ducts running through a crawl space preset added issues by moving contaminated air forcibly through the home. Many of these systems suffer from poor installations, unsealed ducts, and condensation prone areas that can compound the pest and moisture problems a crawl space has.

For homes that have completely fixed and closed a crawl space, but did not deploy a monitoring kit, homeowners find themselves in the dark again about what's going on beneath their homes. If the job was not properly executed, or an event has threatened the space's integrity, moisture issues could invade the space again and cost the homeowner more time and money to resolve.
