Common Crawl Space Causes

From the frequent rainfalls in Raleigh to the humid, warm summers in Northern North Carolina, the climate plays a significant role in the condition of your crawl space. The soil in the region is another big factor. Although soil types range from the well-drained Cecil soil in Northern North Carolina to the clay sand mixed soil near Raleigh and sandy loam soil near Wilmington– each presents a unique condition for crawl space. Continue reading to learn more about the top crawl space problem causes.

Stack Effect

One of the main concerns of crawl space problems is that they do not stay in the crawl space. Thanks to the stack effect, air from the crawl space is pulled up through the entire house before escaping through the roof. Even the most insulated roof has about a 50 percent air escape. Meaning 50 percent of the air your breath is coming from the crawl space. Musty odors, mold spores, and pest droppings are circulated throughout your home and can lead to increased allergies and respiratory problems, especially for the elderly and young children.

Open Doors & Vents

At one time, not all that long ago, it was considered good building practice to add crawl space vents into all homes. The idea was that vents would allow air to circulate through the crawl space and allow fresh air to replace the stale, humid air trapped. We now know these vents do more harm than good. From high humidity to mold and wood rot, your open vents are to be blamed for a lot of the crawl space moisture damage you are experiencing. But what do you do if you have a home with existing vents? Tar Heel has the solution with air-tight vent covers.

Humidity

It might sound harmless, but humidity in your crawl space is arguably the second biggest cause of moisture problems at your North Carolina home. While there are several areas humidity can enter, through evaporated pooling water, open vents, or through the unfinished dirt floor, humidity not only makes a space uncomfortable but leads to condensation and mold, mildew, and musty odors.
