A vented, dirt-floor crawl space pulls in humid air all summer and holds onto it all winter — encapsulation cuts that cycle off completely, often noticeably within a season.

Four commitments that separate a properly trained crawl space encapsulation crew from a generalist showing up with a truck and a hope.
Our crews understand stack effect, dew point, and vapor drive, not just how to lay down a liner.
Crawl space inspections are scheduled quickly, since early mold growth only gets more expensive the longer it sits.
Pricing is based on crawl space square footage and the specific liner thickness recommended, quoted in writing before installation.
We install 12-20 mil reinforced polyethylene, not the thin painter's-grade plastic some crews substitute to cut cost.
We don't run a one-size-fits-all playbook — every crawl space encapsulation job starts from these core service components, adapted to what your property actually needs.
Seams are taped and mechanically fastened at wall terminations so the barrier performs as one continuous system. This is the baseline fix for most crawl spaces showing chronic humidity above 60 percent.
Older homes with foundation vents are often pulling humid outside air in during summer months — the opposite of what venting was originally meant to do.
A properly sized dehumidifier drained to a sump or gravity line keeps relative humidity below the threshold where mold and wood-destroying insects thrive. We size units to cubic footage, not floor area, since ceiling height varies significantly between crawl spaces.
Crawl spaces with a history of standing water need drainage addressed before encapsulation, or the liner just traps water underneath itself.
Prolonged moisture exposure softens floor joists and sill plates well before it's visible from inside the home.
Four steps, start to finish — from the first call to a sealed, humidity-controlled crawl space.
Local dispatchers coordinate directly with crawl-space-certified technicians.
You'll get a text confirmation with an arrival window before the technician heads out.
You'll see photos of any wood rot, mold, or standing water documented before the quote is finalized.
The space isn't complete until humidity readings confirm the system is holding at target levels, not just until the liner is down.
