Crawl space encapsulation contractors in Grand Rapids, MI
GR Crawl Space is an independent directory of crawl space contractors serving Grand Rapids and West Michigan. We are not a contractor. We may pass estimate requests to local contractors, and featured listings are paid. Phone numbers below come from each company's own site. We do not show licence numbers, because none of these pages state one we have confirmed.
Know your number before you call — run a cost estimate first.

What public sources actually say about crawl spaces in Kent County. These are not measurements from jobs this site has done.
- Soil
- A Grand Rapids cost guide describes clay-heavy soils across much of Kent County (CrawlSpaceHunt). A local contractor says the area's clay-rich soil can hold moisture (Foundation Systems of Michigan). Drainage varies by lot.
- Humidity
- Measure relative humidity in summer. The EPA advises keeping indoor relative humidity below 60 percent, ideally 30 to 50 percent (U.S. EPA).
- Code
- Kent County is IECC climate zone 5A (DOE county climate guide). For zone 5, the 2021 IECC crawl space wall minimum is R-15 continuous, R-19 cavity, or R-13 cavity plus R-5 continuous. R-30 is the floor value if you insulate the floor instead (Building America Solution Center). The City of Grand Rapids lists a 42-inch frost line depth (ePlan Room).
- Planning band
- One 2026 Grand Rapids cost guide lists $2.94–$7.84 per sq ft for full encapsulation, and $3.82–$10.19 with a dehumidifier (HouseProjectCalc). That is a published planning range, not local job data.
- Permits
- Check with the City of Grand Rapids Development Center, or your township, about which permits apply. Adding a dehumidifier circuit or a sump may involve separate electrical or plumbing permits (building permit application).
