Crawl Space Doors
Many crawl space doors like this one are uninsulated and often let outside air and moisture enter the crawl space. The door is left exposed to the outside elements and becomes warped or damaged, and does not help to seal the crawl space.
Hanging Fiberglass
Fiberglass is installed between the floor joists within the crawl space. The fiberglass absorbs the water, making it heavy, while the water droplets pull apart the fine fibers of this insulation. Gravity causes many pieces to tear and fall to the floor, adding to the debris and puddles within an unsealed crawl space.
Inefficient Vapor Barrier
A basic 6-mil vapor barrier is often found in many unsealed crawl spaces in our area. Holes and rips are often created in this flimsy liner, exposing the dirt floor, and allowing the earth's moisture to rise freely into the crawl space.
Crawl Space Foundation
The foundation walls of this crawl space are porous and allow moisture to pass through the walls. With the dirt floor exposed, due to an inefficient vapor barrier, and the foundation walls remaining unsealed, air and moisture will constantly infiltrate this crawl space until it is encapsulated.
Mold and Mildew
Mold and mildew will grow on any organic material in crawl space, such as these floor joists if the temperatures are warm enough and the relative humidity is high enough. Mold spores leaking up into the floors above can cause families health issues, such as irritations and asthma.
