A vented, dirt-floor crawl space pulls in humid air all summer and stays damp all winter — encapsulation seals that cycle off completely and it usually shows up on your energy bill within a season.

What "specialized" actually means for crawl space encapsulation at our company — not a marketing word, a set of specific practices.
Certification covers proper venting decisions, dehumidifier sizing, and moisture-source diagnosis before any liner goes down.
Local crews carry moisture meters and basic inspection gear on every truck, so the first visit produces real findings, not just a callback.
Pricing is based on crawl space square footage and the specific liner mil-thickness recommended, quoted in writing before installation.
Dehumidifiers, when installed, are crawl-space-rated units with drainage tied into an existing sump or gravity discharge, sized to the cubic footage of the space.
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, not a patchwork of loose sheeting. This is the baseline fix for most crawl spaces showing chronic humidity above 60%.
Older homes with foundation vents are actually pulling humid outside air in during summer months — the opposite of what venting was originally intended to do.
A properly sized dehumidifier, drained to a sump pit or gravity line, keeps relative humidity below the 55% threshold where mold and wood-destroying insects thrive. We size units to cubic footage, not square footage, since ceiling height varies a lot 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.
Here's the exact path from your call to a finished encapsulation.
Tell dispatch what you're noticing — musty smell, visible mold, sagging floors above — and they'll route the right crew with moisture-testing equipment.
Most Redgranite, WI inspections are scheduled within a day or two, since crawl space issues tend to compound with every humid week that passes.
You'll see photos of any wood rot, mold growth, or standing water documented before the quote is finalized.
We're glad to walk you through the finished space with a moisture meter so you can see the readings yourself.
