Our Crawl Space Encapsulation Service Lineup

Each service below is scoped specifically to crawl space encapsulation, not a generic waterproofing menu with the name swapped in.

Full Encapsulation with Reinforced Vapor Barrier

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.

Vent Sealing & Air Leakage Control

We seal vents with rigid foam or vent covers as part of a full encapsulation, converting the space to a sealed, conditioned environment.

Crawl Space Dehumidification

Even a fully encapsulated space can hold residual moisture from concrete curing, plumbing condensation, or seasonal swings. We size units to cubic footage, not floor area, since ceiling height varies significantly between crawl spaces.

Sump Integration for Standing Water

We install a dedicated sump basin and pump sized to the space's water intake, tied into the encapsulation system's drainage channel.

Joist & Subfloor Inspection

Prolonged moisture exposure softens floor joists and sill plates well before it's visible from inside the home.

Frequently Asked Questions

The questions Unicoi customers ask us before booking crawl space encapsulation service.

How quickly can someone inspect my crawl space in Unicoi, TN?+
Most Unicoi, TN inspections are scheduled within a day or two, since moisture issues tend to worsen the longer they sit.
Do you provide upfront, flat-rate pricing?+
Yes, pricing is based on crawl space square footage and the equipment recommended, quoted in writing before work starts.
Will encapsulation actually lower humidity, or just cover the dirt?+
Sealing the vents and adding dehumidification where needed addresses the actual moisture source, not just the visible dirt floor.
What mil-thickness liner do you use?+
We typically install 12-20 mil reinforced polyethylene depending on foot traffic and pier count in your specific space.
Do I need a dehumidifier if I'm already encapsulating?+
It depends on your baseline humidity readings; some fully sealed spaces don't need one, others do — we recommend based on measurements, not a blanket upsell.
Is crawl space encapsulation covered by a warranty?+
Yes, our liner and seam work carries a written warranty against failure or separation.
Can encapsulation help with allergy symptoms in the home?+
Many customers report the air feeling noticeably fresher after encapsulation, likely tied to reduced mold spore circulation, though results vary by household.
