Heavy-gauge vapor barriers, sealed foundation vents, and a dedicated sump discharge line so your Lansing, MI 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.
Every crew member is trained specifically on liner installation, seam sealing, and vent encapsulation, not general basement work.
Lansing, MI 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.
A dedicated crawl space dehumidifier is sized to your square footage, not a one-size-fits-all unit.
Every Lansing, MI Crawl Space Encapsulation job starts with an inspection, not a generic package — here's what that typically includes.
Before any liner goes down, we pump out existing standing water and remove debris left behind by prior drainage failures.
Liner thickness is selected based on foot traffic and how the space will be used going forward, not a flat default.
Sealed vents are paired with mechanical dehumidification so the space doesn't just trap humidity instead of venting it.
A crawl space needs its own sump basin and discharge line separate from any basement system, since the two spaces drain differently.
We also check subfloor insulation for water damage and replace anything compromised before closing the liner.
We ask about standing water, musty odor, and vent condition to gauge scope before scheduling the inspection.
We take humidity and moisture readings to establish a baseline before recommending a system.
We explain trade-offs between liner thickness options so you can choose what fits your budget and goals.
Most residential encapsulations finish in one to two days depending on square footage and access.
"Found out our old vapor barrier had huge gaps at every seam. They redid it properly and sealed the vents too."
— Lansing Homeowner
"Wood floors upstairs were starting to cup from crawl space humidity. Encapsulation plus a dehumidifier stopped it before we had to replace flooring."
— Lansing Customer
"They caught duct condensation we didn't even know was happening down there. Sealed everything up during the same visit."
— Lansing Homeowner
"Humidity reading before was over 80%. After encapsulation it's holding steady in the 50s."
— Lansing Customer
We can scope either option depending on your budget and how severe the existing moisture problem is.
We'll recommend a thickness based on how the space is actually used, not just a default.
In most Lansing, MI climates, yes — open vents pull in humid air that undoes a lot of the benefit of the liner alone.
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.
