Insulation services in Crosby, ND
Williston Insulation is an insulation contractor for Crosby, ND and the farms across Divide County. Crosby is the county seat, about six miles south of the Canadian border, and it takes us about an hour and a half to get there: north on US-85, then east on ND-5. We handle spray foam, blown-in attic insulation, batts, rigid board, air sealing, and removal for houses, shops, and ag buildings. Drew Niskanen quotes and installs the work.
Grenora and Wildrose, on the way up, are covered from this page.
Older houses in a farming county
Crosby did not grow the way Williston and Watford City did during the 2010s. It stayed a farm town and county seat, and its housing reflects that. Most houses are pre-1980, and a good share are much older than that. The pattern is familiar: settled attic insulation, 2x4 walls, uninsulated rim joists over the basement, and in some of the oldest houses, balloon framing that lets air run from the basement straight to the attic.
That last point matters. In a balloon-framed house, the stud bays are open from bottom to top, and until they are blocked or sealed, any attic insulation is sitting on top of a chimney of moving air. We check for it on old Crosby houses before recommending anything.
As far north as it gets
Crosby is about as far north as you can get in North Dakota, in the same Climate Zone 7 as Williston but with nothing to the north but open prairie and Saskatchewan. Winter here is long, and the wind has a clear run at every building. The practical effect is that air sealing matters even more than it does in Williston. A rim joist sealed with closed-cell foam, an attic floor sealed at the top plates and penetrations, and a blocked balloon-framed wall do more for an old Crosby house than any single layer of insulation added on top of leaks.
The farm buildings around Crosby, machine sheds, heated shops, and grain handling buildings, have the usual steel-building problem of condensation in winter once the heat comes on. Foam against the steel is the fix when the building is heated. When it is not, we will tell you to save the money.
Planning a Crosby trip
An hour and a half each way means we plan Crosby carefully. We are glad to do the work, but small jobs do not cover the drive on their own, so we group them: several Crosby jobs in one trip, or a Crosby job combined with work in Grenora or Wildrose along the way. Larger jobs, a full house or a shop, get their own day or more. Tell us what the job involves when you send a quote request and we will be honest about the timing.
Spray foam in Crosby
Crosby's old houses are where closed-cell spray foam at the rim joist makes the biggest difference for the least material. Two inches at the band over the foundation stops the cold air that runs along the floor joists and adds a vapor retarder where one is needed. Heated farm shops get foam against the steel. Attics get blown-in fiberglass after air sealing. The spray foam insulation page covers when we recommend it and when we do not.
What we install in Crosby
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.
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.
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.
Pole Barns & Shops
Closed-cell foam sprayed direct to the steel skin of post-frame barns and shops, stopping the condensation drip and making the building cheap to heat.
Questions from Crosby
Will you come all the way to Crosby for one job?
For a larger job, yes, as a dedicated trip. For a small job like a single rim joist, we group it with other work in Divide County or along US-85 so the drive is not wasted. That can mean waiting for a date. If you know of a neighbor who also needs work, doing both in one trip helps everyone.
What should I expect from a quote for an old Crosby house?
We look at the attic, the rim joist, the basement walls, and whether the house is balloon framed before we quote. The quote usually leads with air sealing and the rim joist, then the attic. If the distance affects the price, we show it as its own line. We do not quote from a phone description.
Do you work on farm shops outside Crosby?
Yes. Heated post-frame and steel shops in Divide County are a good fit for a dedicated trip because they take a full day or more. Closed-cell foam against the steel stops winter condensation. For a cold storage building we will usually say foam is more than it needs, which saves you the trip and the money.
