Why Your Crawl Space Needs Proper Ventilation

Since the house breathes from the bottom up, the last thing you want is to leave openings for outside air to come in. This can allow dirty air from the crawl space to enter your home and cause your family to breathe in dirt and mold particles, causing allergy symptoms and other health issues.

Sealing Crawl Space Vents Can Be The Answer  

Crawl space vents are not always the answer due to their inconsistency. They’re meant to dry out crawl spaces through the use of outside air but unfortunately, they can unintentionally do damage in poor weather conditions involving moisture, freezing temperatures, or humidity.

In order to prevent potential health issues, mold, mildew, odors, and other damage in your crawl space, you should have your crawl space vents sealed off.

By doing so, the sealed vents will help keep outside air and other elements such as insects, overly hot or cold temperatures, and excess moisture away. Our vent covers are mechanically attached to form an airtight bond and they are fast and simple to install.

Why Vented Crawl Spaces Are Trouble

Home builders favor crawl spaces because they’re faster and less expensive to build than a full-blown basement foundation. This type of traditional crawl space utilizes openings or air vents in the crawl space walls so that the air outside can circulate underneath your living space.

If there is any insulation installed, you may find it in the form of fiberglass batts, placed between crawl space joists, while the crawl space’s floor will be made of soil or concrete.

Having this type of crawl space can be troublesome over time, as during the summer, warm and moist air can enter the crawl space, condensing on the cooler crawl space surface. When the crawl space continuously receives this warm air, it can cause moisture to form, which invites mold to grow and causes wood to rot.

The presence of wet wood can also attract insects such as termites and carpenter ants, who want nothing more than to chew up the wood and terrorize your home. Additionally, the fiberglass insulation easily absorbs moisture and may sag or fall out of place, settling onto the crawl space floor. In winter, there’s a new set of problems: the floors become too cold because of the wet and missing insulation, meaning higher heating bills.

One factor that isn’t determined by season is the indoor air pollution that can cause respiratory problems. These problems can be caused by the mold spores that enter the living space through the cracks and gaps in the walls and floors of the crawl space.
