A properly installed vapor barrier blocks ground moisture from reaching your crawl space or basement floor, sealed at every seam and pier.
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.
We follow manufacturer overlap and seam-sealing specifications on every install, not shortcuts that look fine until moisture finds the gaps.
Vapor barrier installation is typically a quicker job than full encapsulation, and we can often schedule Bunker Hill, OR appointments within a few days.
Pricing is based on your space's actual square footage and liner thickness selected, quoted in writing before installation.
We recommend liner thickness based on foot traffic, storage use, and moisture severity, not just selling the thickest option by default.
We scope every Vapor Barrier Installation job in person before quoting it, since two properties with the same symptom rarely need the same fix.
We overlap seams per manufacturer spec and seal them with rated tape, not just tucked edges that separate over time.
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.
This helps us bring the correct liner and sealing materials on the first visit.
A technician measures the space, checks existing ground cover condition if any, and counts piers or posts that will need wrapping.
You'll see the recommended mil thickness, total square footage, and pier wrapping scope broken out with pricing.
Most standard-size installations are completed in a single visit, sealed and ready the same day.

"Recommended a thicker liner since we use the crawl space for storage — made sense once they explained it."
— Bunker Hill Customer

We inspect the full barrier during the visit to make that call honestly.
We use rated pier boots rather than improvised wrapping.
No — a vapor barrier is the ground liner itself, while full encapsulation typically adds vent sealing and dehumidification on top of it.
Most standard-size crawl spaces or basements are completed in a single visit.
It often helps significantly, especially if ground moisture was the primary source, though persistent odors may point to an additional issue worth investigating.
