Crawl Space Encapsulation
Crawl Space Encapsulation Contractors
Crawl space encapsulation turns a damp, dirt-floor gap under your home into a fully sealed, controlled space — the most complete fix available for chronic crawl space moisture. Instead of treating one symptom at a time, encapsulation combines a heavy-duty vapor barrier, professional air sealing, insulation, drainage, and dehumidification into one system, installed by Reed’s Home Solutions throughout Kentucky, Tennessee, Virginia, and West Virginia.
Homeowners searching for crawl space encapsulation contractors are usually dealing with more than one problem at once — musty odors, high energy bills, visible mold, or a crawl space that never quite dries out. Encapsulation addresses all of them together, rather than requiring separate visits for each.
What's Included in Crawl Space Encapsulation
A complete encapsulation system, built from six components that work together — not a single product applied on its own.
Sealing the Space
- 30-mil polyethylene vapor barrier installed across the entire floor and up the walls, blocking ground moisture at the source
- Professional air sealing at rim joists, gaps, and penetrations to stop outside air and humidity from entering
- Structural preparation — addressing any existing damage before the barrier and insulation go in
Controlling the Environment
- Insulation application to keep the space — and the floors above it — at a stable temperature
- Dehumidification systems that maintain humidity levels automatically, year-round
- Drainage solutions for crawl spaces that need standing water managed as part of the encapsulation
Signs Your Crawl Space Needs Encapsulation
Full encapsulation is usually the right call when more than one of these is happening at once — not just a single isolated issue.
What You Might Notice
- A persistent musty odor in the rooms above the crawl space, even when the rest of the house is clean
- Visible mold or mildew on floor joists, subfloor, or stored items in the crawl space
- Cold or uneven floors in winter, especially near exterior walls
- A noticeable increase in heating and cooling costs without an obvious cause
What It Usually Means
- Ground moisture is entering unchecked, which is what a vapor barrier alone addresses
- Air is leaking between the crawl space and living space, driving up energy costs
- Humidity is high enough to support mold growth and pest activity
- Multiple issues together usually point to full encapsulation rather than a single-component fix

Why Homeowners Choose Full Encapsulation
- Eliminates musty odors and improves air quality throughout the home, not just in the crawl space itself.
- Improves energy efficiency and reduces utility costs — a sealed, insulated crawl space loses far less conditioned air.
- Increases home comfort with more consistent temperatures in the rooms above the crawl space.
- Prevents mold, mildew, and pest infestations by removing the moisture they all depend on.
- Protects against structural damage from long-term moisture exposure to floor joists and framing.
- Raises property value and marketability — a documented, professionally encapsulated crawl space is a selling point, not a red flag.
Encapsulation, or Just One Piece of It?
Full encapsulation isn’t always necessary — some crawl spaces just need one component addressed.
Building the Right Scope for Your Crawl Space
If your crawl space just needs ground moisture blocked, a standalone vapor barrier may be enough. If standing water is the main issue, start with waterproofing. Already encapsulated but still humid? A standalone dehumidification system may be all that’s missing. We determine the right scope — full encapsulation or a single fix — during your free inspection.

Crawl Space Encapsulation FAQs
How much does crawl space encapsulation reduce my energy bills?
Homeowners typically see about a 20% reduction in energy usage after encapsulation, since sealing and insulating the crawl space stops conditioned air from escaping and outside air from leaking in. Actual savings depend on your home’s size, current insulation, and HVAC system.
Do I still need a dehumidifier after encapsulation?
In most cases, yes. Sealing the space stops new ground moisture from entering, but humidity already present — from plumbing, ventilation, or seasonal conditions — needs a dehumidifier to actively remove it and keep levels below 60%.
What thickness of vapor barrier does encapsulation use?
We install a 30-mil polyethylene vapor barrier — a heavy-duty, puncture-resistant material built to last, rather than the thin 6 to 10-mil liners sometimes used for basic ground coverage alone.
Will encapsulation get rid of mold that's already there?
Encapsulation removes the moisture mold needs to keep growing, which prevents new growth and stops the spread of existing mold. Mold that’s already established on wood or insulation typically needs to be treated or removed separately as part of the same project.
How long does crawl space encapsulation take?
Most encapsulation projects are completed in one to a few days, depending on the size of the crawl space, its current condition, and how much structural preparation is needed before the barrier and insulation go in.
Do you offer financing for encapsulation?
Yes. Because full encapsulation is a bigger project than a single-component fix, we offer flexible financing to help spread the cost over time. Ask about financing during your free estimate.
