Crawl space vapor barrier in Bozeman, MT - a liner that covers the whole floor
Musty smell, damp dirt or torn plastic under the house? We cover the whole crawl space floor so less ground moisture rises into it.
Should your crawl space get a liner, or be sealed all the way?
A crawl space vapor barrier in Bozeman is a plastic liner laid over the entire dirt floor under your house, and it's the starting point whether you keep the crawl space vented or have it sealed.
Most crawl space calls start with a musty smell, cold floors or old plastic that's torn and bunched against the walls. At Advanced Bozeman Insulation Company we put in liners in Bozeman and the cities around it, including Belgrade, Four Corners and Livingston, and the first thing we settle is whether you want a cover in a vented crawl space or the whole space sealed, because they're two different jobs. If the floors upstairs stay cold too, crawl space insulation can get planned on the same visit.
The price depends on how big the floor is, which of those two jobs you pick, how much has to come out first and whether the air down there needs drying, and the schedule turns on that same clearing out, how easy the space is to reach and whether a permit is involved. Montana now requires construction contractors to be licensed with the state Department of Labor & Industry, and we're fully licensed and insured. Your written estimate spells out what we'd do in your crawl space and in what order.
- Best practice is a puncture-resistant liner over the entire floor, so check every quote covers it all.
- An old liner gets looked at first, since repairing one follows the same steps as putting in new.
- Move what you keep down there before the work day so the liner can cover bare ground everywhere.
What happens after you call about a crawl space liner
From the first call to the walk-through, here's who does what. I do the looking and the estimate myself, and a small crew led by our lead installer does the work, usually with me there too.
Call us or send the form
Call (406) 414-0411 or use the form, and we'll get back to you to set a time. It helps to tell us whether the vents are open, what's stored down there and whether anything in the crawl space burns fuel.
I look and write it up
I come out, crawl in and note anything that has to be fixed before a liner goes down, like debris, old torn plastic or pipes coming through the floor. You get a written estimate that says what we'd do and in what order, so you know where the money goes before you decide anything.
Our crew lays the liner
The crew clears what's left, lays the liner across the whole floor and, on a sealed job, seals the seams and every spot something passes through. We work around your things and pick up after ourselves.
Walk through it together
When it's done we walk through the crawl space with you, or you can stay upstairs and look at it from the hatch, which most people prefer. Satisfaction guaranteed on every job.

(406) 414-0411Questions Bozeman homeowners ask about crawl space vapor barriers
These are the questions people around Bozeman ask most before a crawl space job. If yours isn't here, call (406) 414-0411 and ask me directly.
What does a crawl space vapor barrier do?
A well-installed vapor barrier helps keep ground moisture and soil gases, radon among them, from coming up out of the dirt into your crawl space. It does that best when it covers the whole floor with no bare patches where boxes or debris used to sit.
Can I just close my crawl space vents?
No, closing the vents by themselves can raise the moisture down there and can be deadly if a furnace, water heater or other fuel-burning equipment in the crawl space relies on natural venting. Sealing a vented crawl space takes a plan for the whole space, so we work that out with you before anything gets shut.
How much does crawl space encapsulation cost in Bozeman?
Encapsulating a 1,500 sq ft crawl space with a vapor barrier and a commercial dehumidifier in Bozeman usually costs about $4,700 to $8,700 per job. That's a rough figure for the area, not our price, and it doesn't cover a plain ground cover in a vented space. Your written estimate gives you the firm number for your house.
Who answers permit questions in Bozeman?
The city's Building Division answers questions about permits, plans and inspections at (406) 582-2375 ext. 1. On a permitted job, the city's inspectors need to see anything that will be covered up, so we build that inspection into the schedule before the liner goes down.
How do I know if my crawl space has radon?
The only way to know your home's radon level is to test, according to Montana DEQ's radon program, and the EPA and the Surgeon General recommend testing every home below the third floor. One radon mitigation company describes a sealed liner over the whole crawl space floor with an outside fan pulling suction under it, so a test result tells you whether that's worth talking about.
How long does a crawl space vapor barrier installation take?
The time mostly comes down to how much has to be cleared out, how easy the crawl space is to get into and whether you're covering a vented space or sealing the whole thing. Your written estimate lays out the work and its order, and if a permit and inspection are needed, we plan around them.

Whether liner work needs a City of Bozeman permit isn't spelled out, so we check with the city's Building Division for each job and handle the permit when one's needed. Around Bozeman we often find torn old plastic, stored boxes and vents nobody has checked in years.
