Atlantic City, NJ's Vapor Barrier Installation Specialists: Proper Mil Thickness, Sealed Seams
We match liner thickness to how your Atlantic City, NJ space is actually used, not a one-size-fits-all default.

A vapor barrier installed without properly sealed seams or wrapped piers provides a fraction of the protection it's supposed to, even though it looks complete at a glance. We follow manufacturer overlap and taping specs on every job.
Seam tape and pier wrapping are done to the standard that keeps warranties valid.
Standard-size crawl spaces and basements can frequently be completed in a single visit.
No surprise add-ons — the number we quote covers material and labor for the full scope discussed.
Under-speccing thickness for a heavily used space is one of the most common installation mistakes we see and correct.
Every Atlantic City, NJ Vapor Barrier Installation job starts with an inspection, not a generic package — here's what that typically includes.
Heavy-gauge liner is installed across the entire crawl space floor and up the foundation walls, sealed at every seam to block ground moisture transmission.
This is often done in coordination with a flooring contractor's timeline, and we can work around scheduled installation dates.
We use pier boots designed specifically for this purpose rather than improvised wrapping that fails within a year or two.
Existing vapor barriers with failed or separated seams can often be repaired rather than fully replaced, extending the life of a system that's otherwise sound.
We dispose of old material and debris as part of the job, leaving the space ready for the new barrier.
Tell us the square footage, whether it's a crawl space or basement, and how the space is used so we can recommend the right thickness.
We also check for standing water or excessive debris that would need addressing before liner installation.
You'll see the recommended mil thickness, total square footage, and pier wrapping scope broken out with pricing.
We walk the finished installation with you to confirm seams are properly sealed before calling the job complete.
"They wrapped every single pier, which the last contractor apparently skipped entirely."
— Atlantic City Homeowner
"Recommended a thicker liner since we use the crawl space for storage — made sense once they explained it."
— Atlantic City Customer
"Quick, clean install — done in one afternoon."
— Atlantic City Homeowner
"Appreciated the walkthrough at the end showing us exactly where the seams were sealed."
— Atlantic City Customer
Most residential spaces do well with 12-15 mil; heavier foot traffic or storage use often calls for 20 mil for durability.
Often yes — if the liner itself is largely intact and only seams have failed, seam repair can extend its life without a full redo.
Yes, pier and post wrapping is included in a proper crawl space vapor barrier installation, since unwrapped supports are a common moisture bypass.
No — a vapor barrier is the ground liner itself, while full encapsulation typically adds vent sealing and dehumidification on top of it.
Larger or more complex spaces with extensive pier wrapping may take a bit longer, which we'll flag in the estimate.
It often helps significantly, especially if ground moisture was the primary source, though persistent odors may point to an additional issue worth investigating.
