Bedford crawl space encapsulation — local context
Crawl space encapsulation in Bedford runs $3,000-$25,000 (KB §B1). Encapsulation means a 12-mil wall and 20-mil floor vapor barrier, dimpled drainage matting under the floor barrier with sealed seams, a dehumidifier, and a sump. Bedford sits in Hillsborough County, which the U.S. EPA places in Radon Zone 2 (moderate potential, predicted indoor average 2-4 pCi/L). Per the EPA's Citizen's Guide to Radon, radon moves up from the soil through cracks and holes in the foundation, and an open crawl space is a direct entry path. Radon mitigation, if needed, is a separate add-on, typically $1,950-$2,250. Bedford's eastern edge is the Merrimack River, where USGS runs the "Merrimack R nr Goffs Falls" streamgage (01092000), so riverside, low-lying homes see real moisture load. The town was incorporated in 1750 (U.S. Census), and its older housing predates modern vapor-barrier practice. See our full crawl space services.
What a recent customer said
Gerald and his crew did an excellent job, first cleaning out all the debris and the dislodged insulation in the crawlspace. they were very communicative and understood my concerns and handled them professionally. When they were finished laying the sublayment and the top vinyl covering, carefully taping all the seams they put insulating foam around the perimeter, sealing the top of the vinyl. Gerald communicated two issues that were not part of the contract that I will subsequently take care of myself. Great job, very satisfied.
Frequently asked questions
Is radon a concern for crawl spaces in Bedford, NH?
Yes. The U.S. EPA places Hillsborough County, where Bedford sits, in Radon Zone 2, with a predicted average indoor radon level of 2-4 pCi/L. The EPA's Citizen's Guide to Radon notes that radon moves up from the soil through cracks and holes in the foundation, so an unsealed crawl space is a direct entry path. Encapsulation seals that floor; radon mitigation, if needed, is a separate add-on, typically $1,950-$2,250.
How much does crawl space encapsulation cost in Bedford?
603 prices crawl space encapsulation at $3,000-$25,000 (KB §B1). The range covers the 12-mil wall and 20-mil floor vapor barrier, dimpled drainage matting under the floor barrier with sealed seams, a dehumidifier, and a sump. Radon mitigation is priced separately, typically $1,950-$2,250.
Why do older Bedford homes near the Merrimack need encapsulation?
Bedford was incorporated in 1750 (U.S. Census), so much of its housing predates modern vapor-barrier practice. The town's eastern boundary is the Merrimack River, where USGS runs the Goffs Falls streamgage (01092000), and riverside, low-lying homes carry real moisture load. A sealed 12-mil/20-mil barrier with matting, a dehumidifier, and a sump keeps that ground moisture out of the crawl space.
