Heavy-gauge vapor barriers, sealed foundation vents, and a dedicated sump discharge line so your Detroit, MI crawl space stops feeding moisture into the floor joists above it.
Detroit, MI crawl spaces vary a lot in how they were originally built, and a liner that's correct for one home can be undersized for another depending on foot traffic and storage use. We size thickness to how the space is actually used.
Every crew member is trained specifically on liner installation, seam sealing, and vent encapsulation, not general basement work.
Detroit, 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.
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.
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.
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.
We explain trade-offs between liner thickness options so you can choose what fits your budget and goals.
We re-test humidity after installation to confirm the space is holding at a healthy level before we consider the job done.
"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."
— Detroit Homeowner
"Sump discharge from the old system was dumping water right back next to the foundation. They rerouted it and the crawl space finally dried out."
— Detroit Customer
"They caught duct condensation we didn't even know was happening down there. Sealed everything up during the same visit."
— Detroit Homeowner
"Humidity reading before was over 80%. After encapsulation it's holding steady in the 50s."
— Detroit 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.
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.
Spaces with extensive prior water damage or debris may take longer — we'll give you a realistic estimate up front.
