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.
Our crews are trained in building science fundamentals — stack effect, dew point, vapor drive — not just liner installation.
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.
We install 12–20 mil reinforced polyethylene liners, not the thin painter's-plastic-grade material some crews use 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, not a patchwork of loose sheeting. This is the baseline fix for most crawl spaces showing chronic humidity above 60%.
We seal vents with rigid foam or vent covers as part of a full encapsulation, converting the space to a conditioned, sealed environment.
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. Units include a humidistat so the system only runs when actually needed, not continuously.
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.
Tell dispatch what you're noticing — musty smell, visible mold, sagging floors above — and they'll route the right crew with moisture-testing equipment.
You'll get a text confirmation with an arrival window before the technician heads out.
Pricing is itemized: liner and sealing, vent covers, dehumidifier if recommended, and any sump work needed.
We're glad to walk you through the finished space with a moisture meter so you can see the readings yourself.
