Heavy vapor barrier
A thick, seam-sealed liner across the floor and up the walls — not a thin roll of plastic tossed on the dirt. It blocks ground moisture from rising into the wood and the air above.

Encapsulation, the straight version
What does a full crawl space encapsulation include?
A real encapsulation seals your crawl space off from the ground and the outside air, then keeps it dry. On a typical Atlanta job that means a heavy vapor barrier across the floor and up the walls, every vent and gap sealed shut, and a dehumidifier sized to your square footage holding the humidity down for good. Where it's needed, we add insulation and drainage. It's a system, not a single product — which is exactly why a roll of plastic from the home store doesn't get you there.
When is encapsulation alone not enough?
This is the part the high-pressure outfits skip. Encapsulation is a moisture fix, not a water fix. If water actively pools under your house after a hard rain, wrapping it in plastic seals the water against your foundation and makes things worse.
When we find active water, we deal with it first — that's crawl space waterproofing: interior drainage, a sump pump, and regrading where the yard dumps water at the house — then we encapsulate over a dry space. And if the damp has already gotten into the joists and supports, that's crawl space repair. If anyone quotes you a flat encapsulation for a crawl space that's clearly taking on water, get a second opinion. We'd rather lose the upsell than seal a problem in.
Why do Atlanta crawl spaces need encapsulation?
Our red clay soil doesn't drain like sandy soil. It holds water against your foundation and pushes moisture up through the ground for days after a storm. Stack the long humid stretch from May through September on top of that, and an open vented crawl space stays damp far longer than the national how-to articles assume.
Then there's the housing. A lot of homes around Decatur, Kirkwood, Grant Park, and out through Marietta went up decades ago with open vents and whatever vapor barrier was standard at the time, if any. What passed in 1968 is part of why your floors feel the way they do now. We've spent enough time under Atlanta-area homes to know what your era and neighborhood tend to hide.
What does crawl space encapsulation cost in Atlanta?
Most crawl space encapsulations in metro Atlanta run $5 to $7 per square foot. The total comes down mostly to the size of your crawl space, plus a handful of things that move the number:
| What affects the price | Why it moves the number |
|---|---|
| Square footage of the crawl space | More area means more vapor barrier and a bigger dehumidifier. |
| Access | A tight, low crawl space is slower and harder to work in. |
| Existing damage | Rotted joists or failing supports add repair to the scope. |
| Dehumidifier size | Larger or damper spaces need more capacity. |
| Drainage needs | Active water means a drain and sump on top of the sealing. |
We publish ranges instead of hiding behind "call for a quote," because you deserve to know roughly where you stand before anyone walks your house. The free inspection confirms the exact scope before you commit to anything, and if it's a bigger job we offer interest-free financing so you can spread it out. Every repair we make carries a 2-year warranty.
Can I encapsulate my crawl space myself?
You can buy a roll of vapor barrier at any home store, and plenty of people do. The trouble is that encapsulation isn't the plastic — it's the system. A DIY job almost always means a thin liner with unsealed seams, vents left open, and no dehumidifier, which doesn't control humidity and tends to trap moisture in the wrong places.
We get called out to redo a fair number of these, and the redo usually costs more than doing it right the first time, because now there's plastic to pull out and damage that grew underneath it. If you just want a healthier crawl space on a budget, the honest move is to have us look first and tell you what actually needs doing — sometimes it's less than you'd think.

What's Included
What goes into a full encapsulation
Encapsulation is a system, not a single product. Here's each piece and what it's actually for.
Sealed vents and gaps
Old vented crawl spaces were meant to dry out by airflow. In Atlanta humidity they pull damp air in instead, so we close them up for good.
Properly sized dehumidifier
Sized to your space, not a closet unit. This is what holds the humidity in check year-round once the crawl space is sealed.
Insulation, where it makes sense
Rim joists and walls, to keep the sealed space stable and cut the energy loss that comes from an open crawl space under your floors.
Drainage, when there's active water
If water is getting in, sealing alone traps it. We handle the water first with drainage and a sump, then encapsulate over a dry space.

Frequently Asked
Common questions
What does crawl space encapsulation include?
A heavy seam-sealed vapor barrier on the floor and walls, sealed vents and gaps, and a dehumidifier sized to your space. Depending on what we find, it can also include insulation, drainage, a sump pump, or repairs to wood the moisture already damaged.
Is crawl space encapsulation worth it in Georgia?
For a damp or vented Atlanta crawl space, usually yes. Our humidity and red clay keep crawl spaces wet, and sealing one protects the structure, cuts the musty air coming upstairs, and often helps energy bills. It's less urgent for a space that's already dry and tight, and we'll tell you honestly if that's what we find.
How much does crawl space encapsulation cost in Atlanta?
Most encapsulations run $5 to $7 per square foot, so the total scales with the size of your crawl space, plus access, existing damage, and the dehumidifier and drainage involved. The free inspection confirms the exact scope before you commit.
How long does encapsulation take?
Most jobs take one to three days once we start, depending on the size of the space and whether there's repair or drainage work alongside the sealing. You'll get the timeline in writing before we begin.
Can I encapsulate a crawl space that has standing water?
Not until the water's handled. We add drainage and a sump first, then encapsulate. Sealing over active water just traps it against your foundation.
Will encapsulation get rid of the musty smell in my house?
Most of the time, yes — that smell is usually damp crawl space air working its way upstairs, and sealing and drying the space cuts it off at the source. If there's active mold, we'll flag it and tell you honestly whether it's something we handle or something for a remediation specialist.
Do you offer financing?
Yes. We offer interest-free financing, so you can spread the cost out without paying extra over time. We'll walk you through it when we scope the job.
What areas around Atlanta do you cover?
We work across metro Atlanta — Atlanta, Marietta, Sandy Springs, Decatur, Lawrenceville, Alpharetta, Douglasville, and McDonough, plus the surrounding area. Not sure if you're in range? Ask when you book your inspection.
