Insulation contractor in Bismarck, ND - warmer rooms, done in the right order
R&T Mandan Spray Foam Insulation is an insulation contractor that works in Bismarck homes and businesses, sealing attic gaps, pulling out old insulation that's past saving and adding spray foam or blown-in where rooms run cold.
Bismarck, as we see it from the attic hatch
Bismarck is where a lot of our calls come from, even though we're an insulation contractor based over in Mandan. It's the bigger of the two cities, with older houses near downtown, newer neighborhoods filling in at the edges and plenty of shops and offices mixed in, so one week can take us from a house that's had three owners' worth of attic projects to a business that needs something else entirely.
That mix is why I look before I quote. An older house and a newer one can have the same cold bedroom for completely different reasons.
What working in Bismarck means for your job
Permits here go through the city's Building Inspections Department, and its rules reach into an extra-territorial area past city limits, so a house just outside town may still answer to it. When a job needs a permit, we pull it and set up the inspections, and those dates can shape the schedule as much as the work does. Bismarck doesn't have a general business license right now, so the license worth checking on any contractor is the state one, which the questions below cover.
Price and schedule mostly come down to what's already up there and what has to be fixed before new insulation goes in, and the free estimate is where you get your own number. We do the same work in Mandan and plenty of other cities around both, in the same order every time.
What we find in Bismarck houses
Older houses are where I learned this trade, and Bismarck has plenty where nothing is square and the attic has a story to tell, usually involving mice. The common trouble is old insulation that got wet or filled with droppings, open gaps around can lights, pipes and the hatch, and eave vents buried by whoever topped it up last, so on an attic insulation job we clear and seal first, keep the vents open so the attic can breathe, and get the depth right at the edges instead of piling it in the middle.
Cold floors in the room over the garage and drafty crawl spaces come up a lot too. Foam costs more and seals air while it insulates, so I lean toward it when the ductwork runs through the attic, and otherwise air sealing, closing the gaps first, plus a top-up of blown-in, loose fill sprayed through a hose, usually gets you more for your money.

Call or send the form
Call (701) 299-5063 or use the form and tell us what you're noticing, like a cold room or a power bill that keeps climbing. We'll set up a time to come look.
I come out and look
I check the attic, walls, basement or crawl space myself, including how many inches are already up there and anything that has to be fixed first. It helps if the hatch isn't behind a closet full of boxes.
Go over the estimate together
Your free estimate lays out what has to happen first and what we'd put in. If something's wrong that insulation won't fix, I'll tell you instead of burying it.
Handle permits and plan ahead
If your job needs a permit, we pull it with the city and set up the inspections. For spray foam, I'll tell you the re-entry time, when everyone, pets included, can come back inside, so you can plan the day.
Crew works, I check it
Our crew does the work with me on the job, sealing gaps before any insulation goes in. I look it all over before we pack up, and we clean up so the house is as tidy as we found it.
What insulation work looks like
Bismarck insulation questions we hear
Do I need a permit to insulate my attic in Bismarck?
Insulation on its own isn't named on the city's list of work that needs a permit, but the city also says alterations and repairs to a building need one, so call the Building Inspection Division at (701) 355-1465 to know for sure. The list does name remodels, basement finishes, additions and HVAC work, so insulation that's part of a bigger project can fall under a permit. If you're not sure about yours, ask me and I'll find out.
When does an insulation contractor need a North Dakota license?
Anyone doing a job in North Dakota that costs more than $4,000 has to hold a state contractor license, and that includes subcontractors and contractors from out of state. The Secretary of State issues it, so that's where you check a contractor before you sign, and some trades need specialty licenses on top of it that the state license doesn't cover. We're fully licensed and insured.
How do I request a building inspection in Bismarck?
You request it online through the city's eTRAKiT system at least one day before the date you want, or by calling the department at (701) 355-1465. The permit has to show as issued before an inspection can be booked. On our jobs, we set up the inspections, so you don't have to.
How much does insulation cost for a house in Bismarck?
Your price comes from the free on-site estimate, because the biggest factor is what's already in your attic and what has to happen before anything new goes in. Pulling out soaked or droppings-filled insulation, sealing a lot of gaps, a tight attic that's hard to reach and choosing foam over blown-in all push it up. An attic that only needs sealing and a top-up comes in lower.
What building code does Bismarck use for insulation work?
Bismarck lists the 2021 International codes as adopted, including the Residential Code and the Energy Conservation Code, on the city's building codes page. The city is working on updating to the 2024 editions, but the 2021 list is what it shows as adopted for now. On a permitted job, the inspector checks the work against what the city has adopted.
How do I tell if my older Bismarck house needs more insulation?
Pop the hatch and look, and if you can see the tops of the ceiling joists or the insulation is flattened, stained or full of droppings, it needs work. Cold floors, a hot upstairs and a power bill that keeps creeping up are the other giveaways. When I come out, I'll measure what's up there and tell you whether it needs a top-up or has to come out first.
