Crawl Space Encapsulation
Crawl Space Moisture Control
Crawl Space Encapsulation for a Healthier Home
A damp crawl space can lead to mold growth, musty odors, structural wood damage, and poor indoor air quality throughout your home. Crawl space encapsulation is a solution that seals the crawl space from ground moisture, controls humidity, and improves air quality. A significant portion of the air inside your home comes from the crawl space, and addressing moisture below your floors helps protect your home’s structure while creating a cleaner, healthier living environment above.

Common Signs
There are a few signs that tell you your crawl space may benefit from encapsulation, which include:
- Sagging or rotting wood framing or floor joists
- Increased allergy or asthma symptoms inside the home
- Cold floors or uneven temperatures above the crawl space
- High humidity or condensation under the home
- Standing water or mud on dirt floor after a heavy rain
- Insects, pests, or rodents attracted by moisture
What is CleanSpace®?
CleanSpace® is a durable crawl space encapsulation system designed to seal the crawl space from ground moisture, outside air, and pests. It uses a heavy-duty vapor barrier to cover crawl space floors and walls, helping prevent moisture problems like mold, odors, and wood rot. By turning the crawl space into a cleaner, drier, and more controlled environment, CleanSpace® helps improve indoor air quality, protect your home’s structure, and increase overall comfort and energy efficiency.

Common Questions
Frequently Asked Questions
-
Getting rid of crawl space moisture requires more than a single fix. The first step is crawl space encapsulation, which seals the floor and walls to block ground moisture and outside air from entering. A durable vapor barrier creates a watertight seal that helps keep the space dry. To address any remaining humidity, a crawl space dehumidifier is used to control moisture in the air, helping prevent mold growth, odors, and long-term damage.
-
Your floors feel cold because cold air from the crawl space is moving up into your home. When the crawl space floor, walls, or rim joists aren’t insulated or sealed properly, that cold air seeps through and makes the floors above feel icy. Insulating these areas helps keep warm air where it belongs. TerraBlock™ adds insulated protection to the crawl space floor, SilverGlo® creates a radiant barrier along the walls, and Froth Pak seals gaps in the rim joists to block outside air. Together, they keep the crawl space warmer, which means warmer floors and lower energy bills.
-
If your crawl space smells musty, mold growth is often the cause. Crawl spaces are naturally dark and damp, creating the perfect environment for mold to grow and odors to develop. As moisture builds up, those smells can travel upward into your living space.
One of the most effective ways to eliminate existing mold odors and prevent them from returning is crawl space encapsulation. An encapsulation system seals the crawl space floor and walls with a durable vapor barrier that blocks out ground moisture, water vapor, and dirt. Many modern encapsulation liners also include antimicrobial protection to help resist mold growth, keeping the crawl space cleaner, drier, and odor-free long term.
-
Mold thrives in environments where moisture and organic materials, like wood, are present, making crawl spaces an ideal place for growth. Left untreated, mold can cause persistent odors and contribute to poor indoor air quality throughout the home. The most effective way to address mold problems is by controlling moisture at its source.
Crawl space encapsulation combined with dehumidification creates a long-term solution. A CleanSpace vapor barrier seals the crawl space floor and walls, blocking moisture from entering through the ground and foundation. Adding a high-performance dehumidifier removes remaining humidity from the air, creating a dry, controlled environment where mold struggles to survive and odors are eliminated.
