Crawl Space Encapsulation
Full encapsulation wraps your crawl space in a heavy-duty vapor barrier and seals out the moisture driving mold, musty odors, and wood rot across Upstate South Carolina homes.
What Encapsulation Means
A complete moisture barrier for the foundation of your home
Encapsulation is the process of fully sealing your crawl space from the ground and outside air. We line the floor and walls with a thick, reinforced vapor barrier, seal the vents and seams, and control humidity so moisture can no longer rot your joists or feed mold. The result is a clean, dry, conditioned space beneath your home — and noticeably better air upstairs.
20-mil
Reinforced vapor barrier — puncture-resistant and built for decades.
Up to 50%
Less humidity beneath your home once vents and seams are sealed.
Lifetime
Warranty on the barrier system, backed by local crews you can reach.
What’s Included
Every part of a proper encapsulation
No shortcuts and no partial jobs. Each system below is part of how we seal a crawl space for good.
Heavy-Duty Vapor Barrier
A 20-mil reinforced liner across the floor and walls, overlapped and sealed at every seam.
Vent & Wall Sealing
Crawl space vents and rim joists are sealed to stop humid outside air from getting in.
Drainage & Sump
Where water intrudes, we add drainage and a sump pump to move it safely away.
Dehumidification
An energy-efficient dehumidifier keeps the sealed space at a healthy, stable humidity.
Insulation
Foundation walls are insulated to improve comfort and lower energy loss through the floor.
Final Inspection
We document the finished system with photos so you can see exactly what was done.
Why It’s Worth It
What a sealed crawl space does for your home
Cleaner indoor air
Up to half of the air upstairs comes from below. Sealing the crawl space means fewer musty odors and allergens in your living space.
Protected structure
Dry joists and subfloor won’t rot, sag, or attract termites — protecting the most expensive part of your home.
Lower energy bills
A conditioned, insulated crawl space takes load off your HVAC, so floors feel warmer and your system runs less.
Higher home value
A documented, warrantied encapsulation is a clear selling point and a passed inspection waiting to happen.
