The Basics

What Is Crawlspace Encapsulation?

Encapsulation seals your crawlspace from the ground up. We line the floor and walls with a heavy 20-mil vapor barrier, close and insulate the vents, treat any mold, and add a commercial dehumidifier that keeps humidity locked below 60% — for good.

The result is a clean, dry, conditioned space instead of a damp dirt cellar feeding moisture into your home. It's the difference between a band-aid and a cure.

Vapor Barrier vs. Full Encapsulation
Plastic on the floor
A loose vapor barrier alone — vents stay open, walls exposed, humidity untouched.
Full encapsulation
Floor, walls, vents, and rim joists sealed — plus active dehumidification. A complete system.

Why Kansas City Homes Need It

40"
Annual Rainfall

All that water hits our clay soil and has nowhere to go but under your home.

90%
Summer Humidity

Hot, humid air pours through open vents, hits cool ground, and condenses into moisture.

Clay
Soil

KC's dense clay traps water against your foundation instead of draining it away.

Questions

Encapsulation FAQ

How long does encapsulation take?

Most KC homes are done in 1–2 days. Larger spaces or jobs needing mold remediation may take up to 3 days.

Do I need to leave my home?

No. Our crew works under the house — you can go about your normal day. We'll let you know when we need access to entry points.

How long does it last?

A properly installed system lasts 20–30 years. The vapor barrier carries a 25-year manufacturer warranty, and our labor is backed by the lifetime Dry Crawlspace Promise.

Does homeowner's insurance cover it?

Usually no — it's preventive. But if moisture has already caused structural damage, some policies may cover remediation. We document everything for your insurer.

Vapor barrier vs. full encapsulation?

A vapor barrier is just plastic on the floor. Full encapsulation seals the floor, walls, vents, and rim joists and adds active dehumidification. Band-aid vs. cure.

Will this lower my energy bills?

Yes — sealed crawlspaces improve efficiency 15–20% in most KC homes by eliminating the biggest source of uncontrolled air and moisture.
