Crawl Space Sealing & Vapor Barrier Installation
Moisture and radon gas often find their way into homes through unsealed crawl spaces. These areas are out of sight, but they can have a big impact on your home’s air quality and overall safety. At BreatheWell Radon Solutions, we provide professional crawl space sealing and vapor barrier installation to protect your home and keep your family breathing healthy air.
Why Crawl Space Sealing Matters
An open or poorly sealed crawl space can let in more than just damp air. It often becomes a pathway for:
- Radon gas rising from the soil beneath your home.
- Moisture and humidity that can cause mold growth and wood rot.
- Cold drafts that make your home less energy efficient.
Because radon is odorless and invisible, many homeowners don’t realize their crawl space is contributing to unsafe levels indoors. Sealing this area helps block radon entry while also controlling moisture problems.
What Is a Vapor Barrier?
A vapor barrier is a heavy-duty plastic liner that covers the crawl space floor and sometimes the walls. Think of it as a protective shield between the ground and your living space. It prevents ground moisture from evaporating into the air and reduces the conditions that radon and mold thrive in.
When installed correctly, a vapor barrier also helps:
- Keep your crawl space dry and clean.
- Reduce musty odors in the home.
- Improve heating and cooling efficiency.
- Create a healthier environment overall.
Our Process
At BreatheWell, we follow EPA and industry best practices to ensure every crawl space is sealed the right way. Our process includes:
- Inspection – We assess your crawl space to identify radon entry points, moisture concerns, and structural details.
- Preparation – We clear debris and smooth the surface for proper installation.
- Sealing – Gaps, cracks, and penetrations are sealed with professional-grade materials.
- Vapor Barrier Installation – We install a thick, durable liner that is secured and sealed at all seams.
- Integration with Radon Mitigation – If your home requires radon reduction, we tie the crawl space sealing directly into your radon system for maximum protection.
Protect Your Home and Family
A sealed crawl space with a quality vapor barrier is one of the best ways to defend against radon, mold, and excess humidity.
It’s a smart investment in both your home’s structure and your family’s health.

Crawl Space Sealing FAQ
What does crawl space sealing do?
Crawl space sealing blocks radon, moisture, and outside air from entering your home through the ground. It helps keep the area dry, clean, and safe.
How does a vapor barrier help with radon?
A vapor barrier creates a protective layer between the soil and your living space. This helps reduce radon gas entry and keeps moisture from rising into the home.
Will sealing my crawl space help with mold?
Yes. By lowering moisture and humidity, crawl space sealing makes it harder for mold to grow and spread in your home.
Do vapor barriers last a long time?
When installed with professional-grade materials, vapor barriers are designed to last for many years without tearing or breaking down.
Can crawl space sealing be part of a radon mitigation system?
Absolutely. At BreatheWell, we often connect crawl space sealing directly into a radon mitigation system for maximum protection.
