Your Local Crawl Space Repair Experts
Moisture can enter a house in various ways. Poor roofing, broken gutters and foundation issues are the main reasons behind infiltration. However, crawl space vents can act as another gateway for moisture entry and pose a detrimental risk for mold growth and pest infestation.
The Crack Guys knows how to keep your crawl space in good condition. One question we often get is: “When should crawl space vents remain open or closed?” The short answer is: it depends on the weather! Ventilation plays a crucial role in maintaining your home’s health, preventing moisture buildup and protecting your foundation. We share insights to help you determine when to open or close vents.
Foundation Vents: Open Or Closed?
Crawl space vents are essential for ensuring proper airflow under your home. However, the decision to open or close them can depend on several factors, such as the weather and the season. Properly managing your vents can help you prevent mold, mildew and damage to your property.
When To Leave Crawl Space Vents Open
During warmer months or when the weather is dry, it’s generally best to leave vents open. Here’s why:
- Improve airflow — Open vents allow fresh air to circulate, keeping humidity levels low and moisture at bay.
- Prevent mold and mildew — Adequate airflow prevents the growth of mold, which thrives in damp, enclosed spaces.
- Regulate temperature — Proper ventilation keeps the crawl space temperature stable. This stability can prevent foundation problems and reduce the load on your HVAC system.
When To Close Crawl Space Vents
It’s best to keep vents closed during the winter. In colder temperatures, closing vents helps prevent cold air from entering your home and freezing pipes. Additionally, if your area is experiencing heavy rain or excessive moisture, closing the vents can prevent water from accumulating in the crawl space.
Should Vents Under House Be Open Or Closed In Summer?
During the summer, it’s essential to keep your crawl space vents open. Open vents help prevent moisture from accumulating by allowing air to circulate and reduce humidity. Proper ventilation also prevents the space from becoming too hot, which can negatively impact your home’s foundation and increase energy consumption.
In hot, humid weather, keeping the vents open ensures your crawl space remains dry and well-ventilated. Investing in professional crawl space encapsulation can also help control humidity levels beneath your home, especially during Tennessee and Alabama summers.
What Temperature To Close Crawl Space Vents
Knowing when to close your crawl space vents can make a big difference in protecting your home. Close the vents when temperatures dip below 40 degrees Fahrenheit to prevent cold air from entering and freezing your pipes. Doing so will help you maintain a balanced and protected crawl space throughout the year.
