CAUSES OF CRAWL SPACE DAMAGE
There are many causes of crawl space water intrusion and damage. Here is a guide to a few of the most common that may be impacting your home.
There is always air movement between your crawl space and home. It is driven by the “stack effect” or convection. Warm air in the upper level of your home rises and is expelled through windows, vents, and cracks. As it rises, air from your crawl space rushes in to fill the vacuum. Air from your crawl space enters your home along with everything in it. Odors, mold spores, and dust mite feces enter your living area.
Crawl space vents are an old “solution” that actually cause a lot of problems for crawl spaces. Vents let in moisture, water, and air. This moisture causes walls, floor joists, and insulation to get wet with condensation. These vents are one of the biggest factors in raising relative humidity.
Water can leak through dirt crawl space floors and create huge moisture issues throughout your home. A dirt floor does not separate your home from the earth, which causes insects, pests, moisture, and mold to easily enter your home.
During construction, the area around the home must be filled with loose dirt. When this fill soil is not compacted properly, it can compress under the weight of the home, causing settlement. When the soil around your home settles, water can easily flow towards your foundation walls. Concrete, brick, and stone walls are porous and allow this water to enter your home.
