It’s Hot Outside! What’s Going on in my Crawl Space?
Here we are in the middle of summer. It’s a hundred degrees outside and the humidity is almost unbearable… so what is going on under your house in the crawl space?
As the hot humid air enters through the foundation vents into the cool crawl space, the relative humidity is rising and rising. Think about the hot air on a cool glass of iced tea or the mirrors in your bathroom after a hot steamy shower. Condensation begins to form on just about everything.
Water is dripping from the HVAC… condensation is formed on top of and below the moisture barrier… water is beading up on the fiber glass insulation above… it’s one hot, sweaty, wet mess!
The moisture that you see is only an indication that a bigger problem may be present. It’s the moisture that we can’t see that presents the biggest problems. Many homes that we’ve been inspecting recently have wood moisture contents above 25% which makes the wood soft and weak. It’s not unusual to be able to press a screwdriver far into the weak wood once it’s become saturated.
Relative humidity levels are reaching above 90% on almost every house. This is creating the perfect environment for wood to rot, structural problems to manifest, and mold to grow in many crawl spaces in the Hampton Roads area.
Often times, we will recommend a crawl space encapsulation to remedy the crawl space moisture. This method of crawl space sealing guarantees 60% relative humidity or less all year ’round by using special install techniques and a crawl space dehumidifier.

Wet and damp crawl spaces are not the most comfortable spaces to be in the summer. Still, even though you cannot see what’s going on in the crawl space, it is still a critically important area of the home. We highly recommend taking a quick peak at your current condition or have one of our expert inspectors do the nasty work for you! It could save you big and like a lot of our customers tell us, give you peace of mind.
LOOK OUT AT THE PHOTO! The framing in this crawl space in Newport News is completely saturated because of an air handler in the closet above. The cool air from the air handler has cooled the surface of the wood which is the perfect condition for moisture to maximize on a surface! Mold growth and wood rot are evident… but we can help!
