The traditional method of crawl space moisture control in the Charlotte area was to install vents in the crawl space walls and let outside air circulate throughout the crawlspace area, free-flowing fresh air in and out of the crawlspace vent providing ventilation to the area.

Sounds good but when you actually examine the theory, especially in our Charlotte NC  climate, venting crawl spaces is a real problem.

The warm, moist summer air enters the crawl space and interacts with cooler HVAC ducts, drainage pipes, water pipes causing condensation on these surfaces in addition to the moisture contributed by the uncovered ground floor.

Over time the home’s wooden structural support; floor joists, sill plates, girders, and rim joists increase in moisture content until they reach a point that sustains mold and mildew growth contributing to rot and insect infestation.

The fiberglass batt insulation between the floor joists easily absorbs the crawlspace moisture reducing the insulating factor, sagging and falling on the floor, also called tagging.

The result is a crawl space room filled with musty odors and mold spores waiting to be uplifted into the living areas by the “stack effect”, increased heating bills and possibly allergy/asthma health problems for the family.

So if your ventilated crawl space is still utilizing stationary crawlspace vents, do yourself and family a favor and give CCSS a call.

We’ll provide a free crawlspace moisture evaluation and let you know what, if anything, needs to be done to solve existing ventilated crawlspace problems.

Currently CCSS does the majority of Michael and Billy’s crawlspace and basement repair work as a subcontractor.
