Crawl Space Encapsulation
in Asheville, NC
Improve Indoor Air Quality & Prevent Moisture Issues
Homes in Asheville deal with long periods of humidity, heavy rainfall, and moisture that can collect under the home. Crawl space encapsulation creates a controlled environment beneath your house, helping reduce moisture, improve air quality, and protect the structure. A-1 Pest Control starts every project with a free crawl space inspection so the solution fits the conditions we find, not a template.
During your free inspection, we document the crawl space conditions with photos and look for standing water, water vapor, and early wood rot. If we find moisture entry, we’ll recommend the right order of repairs before installing a vapor barrier.

Why Crawl Space Encapsulation Matters in Asheville
In Asheville’s climate, moisture problems can develop quickly. Crawl space encapsulation helps:
- Control high humidity levels
- Reduce mold and mildew growth
- Lower the risk of wood rot and structural damage
- Improve indoor air quality
- Reduce pest activity tied to damp conditions
When the crawl space stays dry and stable, the rest of the home benefits. A sealed crawl space can also support HVAC equipment performance and indoor air quality by reducing damp air movement into the home.
Quick Stats and Research Worth Knowing
The EPA recommends keeping indoor humidity in the 30-60% range to reduce mold growth risk.
NC State Extension notes the EPA guidance is below 60%, ideally 30-50%, for mold prevention.
Building Science research explains that conditioned (sealed) crawl spaces generally perform better than vented crawl spaces for comfort, durability, and energy outcomes.
Building Science also notes that sustained high relative humidity at surfaces (around 70%+) increases risk for mold and moisture-related deterioration.
What Crawl Space Encapsulation Includes
Crawl space encapsulation in Asheville typically involves:
- Sealing vents and air leaks
- Installing a reinforced vapor barrier
- Extending liner material up foundation walls
- Adding a crawl space dehumidifier
- Creating a space that is completely sealed from outdoor moisture
- Sealing and taping the vapor barrier to reduce water vapor movement
- Adding a wall liner on foundation walls when needed for a more complete seal
In homes with active water issues, additional waterproofing solutions like a drainage system or sump pump may be recommended before encapsulation begins.

- Long-term protection against conditions that attract pests
This approach helps protect the crawl space from repeating problems and supports long-term durability.

Frequently Asked Questions
Do I need a dehumidifier if I encapsulate my crawl space?
Yes—even sealed spaces hold some residual humidity. A dehumidifier keeps your air dry and mold-free.
When should you not encapsulate your crawl space?
If you have major drainage or structural issues, those should be addressed first.
Is encapsulation the same as waterproofing?
Encapsulation is part of a larger waterproofing system that includes sealing, insulation, sump pump, and drainage control.
How long does crawl space encapsulation take?
Most jobs take 2–5 days, depending on the size and condition of your crawl space.
How do I maintain my crawl space once it’s encapsulated?
We recommend annual inspections and dehumidifier checks to ensure lasting performance. As part of our crawlspace encapsulation in Asheville, we will provide a thorough inspection and provide follow-up tips.
