Hampton Falls crawl space encapsulation — local context
If your Hampton Falls crawl space stays damp, the cause is usually the town's tidal-marsh setting. Per Wikipedia, Hampton Falls sits in Rockingham County and is drained by the Hampton Falls and Taylor Rivers — part of the Hampton River watershed reaching the Atlantic via Hampton Harbor. Wikipedia also notes nearly 1,000 of the Seabrook-Hamptons Estuary's ~4,400 salt-marsh acres lie within Hampton Falls, a high-water-table profile that pushes moisture into crawl spaces. The EPA places Rockingham County in Radon Zone 2 (moderate), and a crawl space is a radon entry path. With European settlement dating to 1638 (town grant 1726, per Wikipedia), many homes here sit on fieldstone foundations — our specialty. Encapsulation = a 12-mil wall / 20-mil floor vapor barrier plus dimpled drainage matting, a dehumidifier, and a sump. Crawl space encapsulation runs $3,000–$25,000. Radon mitigation, if needed, is a separate add-on, typically $1,950–$2,250. See our crawl space services or radon mitigation.
What a recent customer said
From our initial meeting with Rich to project close out with Nik 603Basement did not disappoint! We have a 12-18 inch crawl space under our house. Toni, Erik, Chris and Angel worked tirelessly in that tight space for over a week to clean out old debris, run a sump pump, humidifier, vapor barrier and spray foam to dry out the space and preserve our home. The sump worked overtime to keep our space dry during the torrential Christmas downpour. We cannot say enough about this team's customer service and project commitment! Thanks 603B we will be calling you for future projects and referring friends. — Ian and Shawna Evans
Frequently asked questions
Why do Hampton Falls crawl spaces get so damp?
The town's hydrology drives it. Per Wikipedia, Hampton Falls is drained by the Hampton Falls and Taylor Rivers within the Hampton River watershed to the Atlantic, and nearly 1,000 acres of the Seabrook-Hamptons salt marsh lie within town. That tidal, high-water-table setting pushes humidity and standing water into crawl spaces, which encapsulation — a sealed vapor barrier, dimpled matting, dehumidifier, and sump — is built to control.
Does my Hampton Falls crawl space need radon mitigation too?
Possibly. The EPA places Rockingham County, where Hampton Falls sits, in Radon Zone 2 (moderate potential), and a crawl space is a common radon entry path. The EPA advises testing every home regardless of zone. Radon mitigation is a separate add-on from encapsulation, typically $1,950–$2,250, so we test first and only add it if your levels call for it.
Can you encapsulate an older Hampton Falls home with a fieldstone foundation?
Yes — that's our specialty. Hampton Falls was settled by Europeans in 1638 and granted as a town in 1726 (per Wikipedia), so many homes here sit on fieldstone foundations. We tailor the 12-mil wall / 20-mil floor vapor barrier, drainage matting, dehumidifier, and sump to irregular historic crawl spaces. Crawl space encapsulation runs $3,000–$25,000 depending on size and condition.
