Insulation services in Culbertson, MT
Williston Insulation handles insulation for Culbertson, MT, about 45 minutes west of our shop on US-2. Culbertson sits on the Missouri River in Roosevelt County, where US-2 meets MT-16, about 23 miles past the North Dakota line. We do spray foam, blown-in attic insulation, batts, rigid board, air sealing, and removal for houses, shops, and farm buildings in town and along the river. Drew Niskanen quotes and installs the work. Bainville, on the way, is covered from this page.
A highway town with older houses
Culbertson is a small town at the junction of US-2 and MT-16, and most of its houses are older: 1950s through 1970s stock, with some earlier houses and only a few newer ones. The pattern matches the rest of the region. Attic insulation that has settled to a few inches, 2x4 walls with little or no insulation, basements with bare rim joists, and attic hatches with nothing on them.
The larger buildings are ag and highway: machine sheds, heated shops, grain handling, and truck and equipment yards along US-2. Many of those shops were built as cold shells. Once a heater goes in, the steel roof sweats in winter and drips on whatever is underneath.
Between the river and the prairie
Culbertson is on the Missouri River, with the open prairie rising right behind it. It gets the valley's still, cold nights and the prairie's wind, depending on the day. Climate Zone 7 winters here run well below zero for long stretches. The practical result is that air sealing matters first, and vapor control matters at the rim joist and in crawl spaces.
Two inches of closed-cell spray foam at the rim joist handles both: it seals the band over the foundation and acts as a vapor retarder. The attic above gets air sealed at the top plates and penetrations, then blown-in fiberglass toward the R-60 ceiling minimum. That order, seal first and then insulate, is what makes an old house here feel different in January.

Spray foam in Culbertson
In Culbertson, spray foam is mostly a rim joist and shop material. The 1950s to 1970s houses in town get two inches of closed-cell at the rim joist, which seals and insulates a spot batts cannot do well and adds a vapor retarder the river climate calls for. Heated ag and highway shops get foam against the steel to stop condensation. Attics get blown-in fiberglass. Our spray foam insulation page explains how we decide.
What we install in Culbertson
Crawl Spaces & Rim Joists
Closed-cell foam on the rim joist and crawl space walls, with a ground vapor barrier, to fix the cold floors and drafts almost every older Williston house has.
Blown-In Attic Insulation
Loose-fill fiberglass or cellulose blown to the Climate Zone 7 target of R-60, with the top plates sealed and the eaves baffled before the first bag goes in.
Air Sealing
Finding and sealing the gaps that let wind push cold air through a house, done before insulation so the insulation can do its job.
Metal Buildings
Closed-cell foam for steel-framed shops, oilfield service buildings, and commercial metal structures, including removal of failed fiberglass blanket.
Questions from Culbertson
Do you take small jobs in Culbertson?
Yes. Mid-sized jobs like an attic or a crawl space go on the calendar normally at this distance. Very small jobs, a single rim joist for example, get grouped with Bainville or other work west of Williston on US-2 so the trip is not mostly driving. If the drive affects the quote, it shows as its own line.
Can you insulate a shop along US-2 in Culbertson while it stays open?
Usually. We work around equipment, mask what needs protecting, and can split a building into sections so the shop keeps running. Closed-cell foam against the steel stops the winter condensation. Lift height, whether the building is heated, and how much is stored against the walls all affect the plan, so we look before quoting.
What is the first thing you check on an older Culbertson house?
The rim joist and the attic floor. Those two spots account for most of the air leakage in a 1950s to 1970s house, and sealing them is what makes added insulation work. We also check the basement walls and the attic hatch. The quote leads with sealing, then the rim joist, then the attic top-up.
