About
The person who quotes it is the person who installs it.
Williston Insulation is owned and run by Drew Niskanen, out of a shop at 1926 44th St W on the west side of Williston. It started in 2026 with a simple idea: sell the assembly the building needs, then install it ourselves.
Why this company exists
Insulation in the Bakken gets sold two ways. A general contractor from a few hundred miles off sprays a rim joist on the way through and never sees the building again, or a lead-gen website with an out-of-state phone number hands your name to whoever bought the territory. Neither one walks your attic.
We're the third option. A Williston shop, one owner, and a habit of telling people what their building actually needs. Sometimes that's closed-cell foam on every surface of a shop. Sometimes it's a day of air sealing and a blown-in top-up, and the foam quote you got elsewhere goes in the drawer.
What we believe about buildings here
Williams County sits in IECC Climate Zone 7, the coldest zone in the lower 48. The code minimums are high for a reason, and a lot of the housing stock around here was insulated to half of them. Wind matters as much as temperature: a house that leaks air loses heat no matter how thick the insulation is. So we treat the building as one continuous line, floor to wall to ceiling, and we don't leave gaps at the rim joist or the top plate because nobody was looking.
We'll install any of the common systems: spray foam, blown-in fiberglass and cellulose, fiberglass batts and mineral wool, rigid foam board, air sealing, and removal of old material. Each one has a place. Knowing which is the job.
Drew
Drew Niskanen owns Williston Insulation and is on every job. He quotes the work, runs the rig, and answers the phone when it rings. There is no sales rep, no crew you haven't met, and no version of the quote that changes once you've signed it.
