Crawl Space Encapsulation

Is Your Crawl Space A Problem Area?

Addressing crawl space problems while they are still manageable will save you money, by keeping you from needing crawl space restoration or remediation in the future. It’s better to proactively control moisture problems, rather than waiting until it’s too late and spending a big chunk of change in repairs due to water damage or fungal growth. Not only can you save money and eliminate future damage with a crawl space encapsulation, but you’ll also be promoting better air quality in the crawl space which leads to better air quality in the living spaces.



Before encapsulation can begin, we’ll inspect your crawl space to help decide whether it requires any remediation or repairs. All crawl spaces are different. And whether your crawl space has a moisture or mold problem, excess water, or even a pest problem, it’s important to inspect the area before beginning a plan of action. See our pre-encapsulation crawl space remediation techniques, designed to prep your crawl space for encapsulation.


Once your crawl space is free of moisture, water or any potential pest threats, it’s time to seal the entire space. Our crawl space encapsulation process involves sealing air gaps, applying a comprehensive vapor barrier, sealing vents with insulation board and finally installing insulation to maintain the perfect humidity level. Foundation walls are wrapped with waterproof insulation and sealed with caulking to prevent any inclimate weather, pesky pests, or unwanted moisture from entering the space.


A dehumidifier helps condition the air inside your crawl space and is effective in controlling your crawl space’s moisture levels, which prevents deterioration of wood framing and the rusting of metal components in your crawl space. An insulated crawl space door further seals the crawl space from external environments.

Sealing Air Gaps

Our specialists will seal all air gaps and penetrations through the foundation wall to further protect your crawl space from potential moisture damage.

Vapor Barrier

A vapor barrier gives 100% coverage from moisture that rises up through the ground, which keeps the moisture from damaging your wood floor system over time. The minimal recommended thickness of a vapor barrier is 6-mil. We recommend 8-mil thickness, as the Moisture Vapor Transmission Rate (MVTR) is minimal from 8-mil and above. A Woven Polyurethane Liner provides the best support for moisture mitigation in the crawl space.

Vents and Crawl Space Door

Sealing crawl space vents with insulation board helps control the climate inside your crawl space, while mitigating humidity and moisture from entering.


Crawl spaces are great (when they’re properly sealed) for moving airflow throughout the home. Your crawl space also allows for easy access to pipes and wiring beneath the home. Keeping your crawl space properly insulated and ventilated can help to reduce energy bills, extend the life of your heating and air ducts, improve air quality and more.

Both! Many homeowners believe that encapsulating their crawl space is enough. However, once the crawl space is sealed, ventilation is essential for preventing mold and mildew growth.

Crawl spaces can be sealed with a ventilation board that should be open during the humid summer months. This allows air to flow through the crawl space, preventing excess moisture and mold to form. Vents should be kept closed in the winter so as not to prevent cool air from freezing the pipes.

Yes. Mold and mildew growth are extremely common for crawl spaces that aren’t properly encapsulated and ventilated. Our mold remediation experts work diligently to remove any signs of mold, fungus or mildew before beginning the encapsulation process.
