Crawl Space Encapsulation
The repair
Complete Crawl Space Encapsulation in Columbus
A musty smell upstairs or damp floors above the crawl space is a moisture problem. Open vents pull humid summer air under the house. That air condenses on the joists and can grow mold on the wood. Moisture also comes through the dirt floor.
The usual repair seals the space. A vapor barrier covers the ground. A liner goes up the walls. We close and seal the foundation vents so humid air stays out. Wet insulation comes out, and new insulation goes in at the rim joist.
Standing water gets a drain and a sump pump in the same job. Mold remediation is included when mold is on the wood.
We look at the crawl space on a free inspection. You see the work, the timeline, and the cost before anything starts. Drainage and encapsulation systems include a lifetime transferable warranty.

Repairs
Our Solutions
The inspection picks the work for this crawl space. A vapor barrier, wall liner, sealed vents, and rim insulation are the usual job.
Vapor barrier
Covers the crawl space floor so moisture in the ground stays out of the air. This is part of the usual encapsulation.
Wall liner
Goes up the crawl space walls and joins the vapor barrier on the floor. Ground moisture stays behind the liner.
Sealed vents
We close and seal the foundation vents. Open vents pull humid summer air under the house, and that air condenses on the joists.
Insulation
Wet insulation comes out. New insulation goes in at the rim joist.
Crawl space drain and sump
Collects water sitting on the floor and sends it out of the crawl space. We add this when the inspection shows standing water.
Mold remediation
Included when mold is on the wood or the insulation. The same job seals the moisture that let the mold grow.
Common questions
Crawl Space Encapsulation FAQs
Why does my crawl space smell musty?
Open vents pull humid summer air under the house. That air condenses on the joists, leaves a musty smell upstairs, and can grow mold on the wood. Moisture also comes through the dirt floor. The free inspection finds which of those is happening.
Do you close the crawl space vents?
Yes. The usual job closes and seals the foundation vents, covers the ground with a vapor barrier, and runs a liner up the walls. Wet insulation comes out, and new insulation goes in at the rim joist.
What if there is standing water?
A drain and a sump pump go in when water is sitting on the crawl space floor. That work is part of the same job when the inspection shows it.
Do you handle mold in the crawl space?
Yes. Mold remediation is included when mold is on the wood or the insulation. The repair also seals the moisture that let the mold grow.
Will encapsulation fix a sagging floor?
No. Encapsulation seals moisture. A floor that sags or slopes needs foundation repair. The inspection separates them.
How much does crawl space encapsulation cost?
The price depends on the house and the repair. We do not quote a number until we have seen the crawl space. After the inspection you see the work, the timeline, and the cost. Nothing starts until you approve the plan.
Do you warranty the encapsulation?
Drainage and encapsulation systems include a lifetime transferable warranty. Ask about coverage on mold remediation and other work when we walk through the written plan.
