Our crawl space had a musty smell for as long as we've owned the house. The team removed the mold that was there and encapsulated the whole space, and they were careful to work around our radon vent pipe the whole time.

Very thorough mold inspection. They explained the lab results in plain words and gave us a fair quote.
Our process
The Crawl Space Encapsulation process in De Witt, IA
Inspect
We assess the crawl space for existing mold, moisture level, and any radon mitigation equipment already in place.
Contain
We seal off crawl space access before disturbing any mold-affected wood or insulation.
Remove
Mold-affected material is removed and framing is cleaned and treated where salvageable.
Dry
A sealed vapor barrier is installed across the floor and up the foundation walls to stop ground moisture.
Verify
We confirm the space is dry and properly sealed, with any radon system left fully functional.

Why crawl spaces grow mold so reliably
Dirt crawl spaces sit close to the ground and pick up moisture through the soil itself, not just from leaks. Combine that with limited airflow and it's one of the most reliable mold environments in a home.
Along the Iowa, spring spring thaw raises the water table temporarily in a lot of areas, which pushes even more moisture up into an unsealed crawl space.
For independent guidance on mold, moisture, and safe cleanup, see EPA: A Brief Guide to Mold, Moisture and Your Home and CDPHE: Iowa Department of Public Health & Environment.
- Ground moisture wicking up through exposed dirt floors
- Spring spring thaw raising soil moisture near the foundation
- Poor ventilation trapping humidity in the space
- Wood framing and subfloor sitting close to damp soil
What encapsulation actually does
Encapsulation means sealing the crawl space with a heavy vapor barrier across the floor and up the foundation walls, cutting off the ground moisture that feeds mold growth long term.
It's a more permanent fix than just cleaning existing mold, since it addresses why the mold grew there in the first place.
- Vapor barrier sealed across the floor and foundation walls
- Seams sealed to create a continuous moisture barrier
- Existing mold removed and framing treated before sealing
- Improved conditions for anything stored or run through the space
Coordinating with radon mitigation systems
A lot of De Witt homes have radon mitigation systems with vent pipes running through the crawl space. Encapsulation has to be done carefully around this equipment so the radon system keeps working exactly as intended.
We coordinate the vapor barrier installation around existing radon vents and sealing points, rather than treating the crawl space as if that system isn't there.
- Vapor barrier installed around existing radon vent piping
- Radon system function checked after encapsulation work
- No disruption to existing mitigation equipment
Is encapsulation right for your crawl space
If your crawl space has recurring mold, a persistent musty smell reaching the floors above, or visible moisture on the soil or framing, encapsulation is worth considering alongside remediation of what's already there.
Good to know
Crawl Space Encapsulation in De Witt, IA: common questions
Do you remove existing mold before encapsulating?
Yes, encapsulating over active mold growth doesn't solve the problem. We remove and treat existing mold first, then install the vapor barrier.
How long does crawl space encapsulation take?
It depends on the size of the crawl space and how much remediation is needed first, but most projects are completed within a few days.
Is my crawl space a good candidate for encapsulation?
Dirt crawl spaces with recurring moisture, musty odors, or visible mold on framing are typically good candidates. We can assess yours during an inspection.
Will encapsulation affect my radon mitigation system?
No, we coordinate the vapor barrier installation carefully around existing radon vent piping so the system continues working as intended.
Does encapsulation stop mold from coming back?
It significantly reduces the ground moisture that feeds mold growth, which is the main reason crawl spaces develop recurring problems.
