How Much Does Crawl Space Work Cost in Boise, ID?

Boise's semi-arid Treasure Valley climate means moisture issues are primarily seasonal, driven by spring snowmelt from the surrounding mountains. The sandy and gravelly soil provides good natural drainage but irrigation from the Boise River canal system can raise local water tables. Radon levels in Ada County are elevated, making combined crawl space and radon projects common. The rapid population growth from West Coast migration has increased contractor demand and costs.

The average crawl space encapsulation project in Boise costs $5,000, which is 9% below the national average of $5,500. Most homeowners in the Boise metro area pay between $2,300 and $12,500, depending on crawl space size, current condition, and the specific services needed.

The Boise market benefits from competitive contractor pricing and a lower cost of living compared to coastal metros. This makes crawl space encapsulation an excellent investment for Boise homeowners, protecting your foundation, improving air quality, and potentially reducing energy costs by 15-20%.
