When the ventilation of your crawl space isn’t configured correctly, it can affect more than just your energy bills. Mold, pest problems, and even structural damage can become serious issues.
Protect your home by understanding common ventilation mistakes and how to correct them before they lead to more costly problems. Here’s what you need to know to keep your home safe and operating efficiently.
Here’s What Happens with Bad Crawl Space Ventilation
Common issues when crawl spaces are poorly ventilated include:
Mold and Mildew
Bad ventilation allows moisture to build up in crawl spaces, creating an ideal environment for mold and mildew to grow. At best, mold and mildew cause musty and unpleasant odors throughout your home. At worst, they affect your home’s air quality and trigger allergies and respiratory problems.
Pests and Vermin
Warm and damp environments attract rodents, insects ,and other pests that can destroy insulation, damage wiring, and eat through wood and drywall.
Higher Heating and Cooling Bills
Poor ventilation can increase humidity levels in your crawl space and eventually throughout your whole house. That forces your heating and cooling systems to work harder, which costs you more money month to month.
Structural Issues
Excessive moisture, coupled with pests, can lead to wood rot and harm the structural of your home. This leads to expensive repairs and safety concerns.
These Crawl Space Ventilation Requirements Help You Avoid Mistakes
With a little know-how and attention to detail, you can avoid these ventilation issues.
Adhere to building codes
Always check local building codes for crawl space ventilation requirements. They detail the minimum guidelines for airflow, rules for vent placement, and other factors to ensure proper ventilation.
Optimize vent placement and usage
Consult with the experts at Crawl Space Care about how to strategically place crawl space vents for optimal airflow and whether to leave them open or closed.
Use a crawl space dehumidifier
A dehumidifier will regulate humidity levels and prevent moisture-related issues both in your crawl space and throughout your whole house. Choose a model designed specifically for crawl spaces for maximum effectiveness.
Exploring Crawl Space Solutions and Options
If ventilation alone doesn’t solve the problem, additional crawl space solutions exist.
- Encapsulation: Encapsulation blocks moisture from seeping through the crawl space’s walls and floor by closing off vents and through the addition of vapor barrier plastic throughout the space.
- Closed crawl spaces: Research and usage studies have found that keeping crawl space vents closed offers the most effective moisture control and significant energy savings when vents are installed properly.
- Vapor barriers: For more minor moisture issues, installing a vapor barrier on the crawl space floor can block moisture from seeping through the ground.
