Common Crawl Space Causes

Understanding why your crawl space is struggling with moisture issues is an important first step to solving the problem. Below are some common reasons you may require crawl space encapsulation.

Over Spanned Joists

If you notice sagging or sloping floors, or gaps between the wall and floorboards, over spanned joists may be the cause. Although there are several reasons your home may be suffering from over spanned joists, wood rot may be the most common. When crawl space moisture is left untreated, wood rot can occur and cause your home’s wooden floor joists to become weak, causing them to sag or no longer support the weight above them.


Although you may not notice standing water in your crawl space, humidity can still be a big problem for your crawl space’s health. High moisture levels in the air lead to mold, mildew, and high energy bills. This humidity is not contained below your floors; it travels into your living spaces, causing homeowners to increase their energy bills by turning down the temperature to remove the unpleasant humidity. 

Stack Effect 

As mentioned above, humidity has a way to travel beyond your crawl space and into the area of your home where you and your family live. But thanks to the stack effect, it’s not just humidity that travels upstairs. It’s also mold spores and pest droppings. The stack effect pulls untreated outside air into the crawl space, where it moves through the home and eventually escapes out of the roof. New outside air is pulled in to replace the escaped air. Even with the best roof insulation, 50 percent of the air you breathe comes from the crawl space. 

Crawl Space Open Vents 

Old construction code told builders it was a good idea to leave open vents inside the crawl space so that air could circulate. Although this has since been found untrue, open vents cause more problems than good. Still, many crawl space vents remain in older homes. These vents allow untreated air from the outside into your home, and are the perfect entry point for groundwater, rodents, and pests.
