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 Gresham, 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.
Under-speccing thickness for a heavily used space is one of the most common installation mistakes we see and correct.
Every Gresham, OR 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.
For unfinished basements, a vapor barrier under future flooring prevents ground moisture from reaching finished materials installed later.
We use pier boots designed specifically for this purpose rather than improvised wrapping that fails within a year or two.
We inspect the full liner before recommending repair versus replacement so you're not paying for a full redo unnecessarily.
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.
We explain why a given thickness fits your space's usage rather than defaulting to the most expensive liner.
We walk the finished installation with you to confirm seams are properly sealed before calling the job complete.
"Old liner in our crawl space was torn and barely covering half the ground. New install with properly sealed seams made an immediate difference in the musty smell."
— Gresham Homeowner
"Recommended a thicker liner since we use the crawl space for storage — made sense once they explained it."
— Gresham Customer
"Seam tape on our old barrier had failed everywhere. They repaired what could be saved instead of pushing a full replacement we didn't need."
— Gresham Homeowner
"Appreciated the walkthrough at the end showing us exactly where the seams were sealed."
— Gresham Customer
We recommend thickness based on how your specific Gresham, OR space is actually used.
We inspect the full barrier during the visit to make that call honestly.
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.
Most standard-size crawl spaces or basements are completed in a single visit.
We can discuss combining it with dehumidification if the smell doesn't fully resolve.
