Schedule Free Inspection

Your crawl space’s health directly correlates with the health of your actual home. Mold, excess humidity, and even pests can get into your home through your crawl space. That is why it is so important to be aware of what causes these problems, so you can prevent them from happening in the future. At Foundation Recovery Systems, we have skilled technicians that are capable of discovering the cause of your crawl space problems. 

Common Causes of Crawl Space Problems

Learning about the causes of problems in your home’s crawl space can help you be more vigilant, so you can catch the issues before they become much worse and more costly. Below, we explain some of the common causes of crawl space damage.

stack effect

The Stack Effect

A phenomenon that occurs in crawl spaces, the stack effect depends on the fact that hot air rises. The air enters through your crawl space, where it then begins to warm up. Once the air is warm, thermodynamics come into play, and the hot air begins to rise. This warm air moves up into the living areas of your home. It then exits out the top of the home. Because of the stack effect, anything in your crawl space like mold and musty odors can circulate throughout the air in the rest of your home. Crawl space encapsulation is the best solution to preventing or limiting the stack effect.

crawl space moisture


A crawl space that has not been encapsulated or waterproofed is very susceptible to outside elements like water. When water gets into your crawl space, it begins to slowly evaporate, creating condensation in the space. This excess humidity can start to cause problems like mold and wood rot in your crawl space. Eventually, you will be able to notice that the living areas of your home are excessively humid and uncomfortable. Humidity in your home can also increase your energy bills.

crawl space vent

Open Crawl Space Vents

It used to be believed that vents in your crawl space were beneficial to the health of your crawl space; however, we now know that they may cause more harm than good. Open crawl space vents allow moisture to get inside the crawl space, causing increased humidity and aiding in the stack effect. If you do not perform proper maintenance on your vents, then they can become lodged open, exposed to water, air, and debris. Your best option is to seal off your vents with airtight vent covers.
