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.

Four commitments that separate a properly trained crawl space encapsulation crew from a generalist showing up with a truck and a hope.
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.
No surprise charges for pier count or vent sealing — those are accounted for during the initial walkthrough.
Seams are heat-taped or mechanically sealed, and liners are run up piers and foundation walls, not just laid flat on the dirt floor.
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. 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.
The space isn't considered complete until relative humidity readings confirm the system is holding at target levels, not just until the liner is down.
What Clio, AL customers are saying after their crawl space encapsulation service.
"The musty smell that used to reach our upstairs bedrooms is completely gone since they encapsulated the crawl space."
"They showed us the mold on the joists with a camera before we ever agreed to anything — appreciated the transparency."
"Dehumidifier they installed keeps the readout right around 45% humidity year-round now. Huge difference from before."
"Sump basin they added handled a heavy rain last month without a drop making it under the new liner."
The questions Clio customers ask us before booking crawl space encapsulation service.
Our crawl space encapsulation crews cover Clio and the surrounding Clio, AL service area, with regional dispatch keeping response times tight regardless of which part of the footprint you're in.
Our encapsulation coverage area grows as we add regional crews, so a past 'outside our area' answer may no longer be accurate.
