Heavy-gauge vapor barriers, sealed foundation vents, and a dedicated sump discharge line so your Charlotte, NC crawl space stops feeding moisture into the floor joists above it.

A rushed encapsulation job with unsealed seams or unwrapped piers looks fine on day one and fails within a season. We treat seam sealing and pier wrapping as core parts of the install, not optional add-ons that get skipped to save time.
We follow manufacturer specs on liner overlap and seam tape so the barrier actually holds up over time.
Charlotte, NC crawl space calls get scheduled fast, especially when there's standing water or an active mold smell involved.
No hourly billing — the number we quote is the number on the final invoice.
We measure relative humidity before and after installation to confirm the space is actually staying below the threshold where mold and wood rot take hold.

We scope every Crawl Space Encapsulation job in person before quoting it, since two properties with the same symptom rarely need the same fix.
Extraction equipment includes submersible pumps sized for tight crawl space access points.
We install heavy-duty liner rated for crawl space conditions, sealed at every seam and pier to stop ground moisture from reaching the floor joists.
Open foundation vents pull in humid outside air, which is often the real driver of Charlotte, NC crawl space condensation — we seal them as part of encapsulation.
A crawl space needs its own sump basin and discharge line separate from any basement system, since the two spaces drain differently.
Exposed ductwork inside an unencapsulated crawl space collects condensation, which we address by insulating and sealing ducts while the space is open.

This helps us bring the right liner thickness and dehumidifier size on the first visit.
We take humidity and moisture readings to establish a baseline before recommending a system.
You'll see square footage, liner grade, vent sealing, and dehumidifier specs broken out in the written estimate.
Most residential encapsulations finish in one to two days depending on square footage and access.

"Our crawl space had standing water and a mold smell we couldn't get rid of no matter what we tried. Full encapsulation with a dehumidifier fixed it in one visit."
— Charlotte Homeowner
"Wood floors upstairs were starting to cup from crawl space humidity. Encapsulation plus a dehumidifier stopped it before we had to replace flooring."
— Charlotte Customer
"They caught duct condensation we didn't even know was happening down there. Sealed everything up during the same visit."
— Charlotte Homeowner
"Musty smell in our upstairs hallway is completely gone now that the crawl space is sealed."
— Charlotte Customer
We can scope either option depending on your budget and how severe the existing moisture problem is.
Most residential spaces do well with a 12-15 mil liner; spaces used for storage or with foot traffic often need 20 mil for durability.
Some jurisdictions have code requirements around vent sealing, which we'll flag during the inspection if relevant.
If the smell persists after encapsulation, that usually points to a separate moisture source we'd need to investigate.
Yes — we extract existing water first, then proceed with liner and vent sealing once the space is dry enough to work safely.
Most residential jobs finish in one to two days depending on square footage and how much prep work is needed.
