About This Service
A damp, drafty crawl space can lead to musty odors, mold, pest intrusion, and uneven temperatures. Our encapsulation service solves those problems at the source.
We install a sealed vapor barrier, perimeter insulation, and humidity control solutions to transform your crawl space into a clean, protected environment that improves comfort, efficiency, and home health for the long term.
Frequently Asked Questions
Does this help with mold or pests?
Yes. Drier conditions make the crawl space less inviting to mold, mildew, insects, and rodents.
How does it impact energy bills?
By reducing air infiltration and ground moisture, encapsulation supports better HVAC performance and lowers heating and cooling costs.
How long does encapsulation last?
When properly installed, an encapsulated crawl space can last more than 20 years with minimal maintenance.
What’s included in the process?
We seal your crawl space with a heavy-duty vapor barrier, insulate exterior walls or the subfloor, and install a dehumidifier when needed for moisture control.
Why encapsulate a crawl space?
Encapsulation controls moisture, blocks outside air, and improves overall energy performance. It also supports healthier indoor air and prevents long-term structural issues.
