Spray foam insulation in Bozeman MT - the right foam in each part of the house
Cold room over the garage or a drafty upstairs? Spray foam fills the gaps and insulates in one go, so the heat stays inside.
Is spray foam the right insulation for your Bozeman house?
Spray foam insulation in Bozeman is foam our crew sprays onto surfaces like the underside of your roof deck, where it seals air leaks and insulates at the same time, so the attic becomes a sealed space instead of a vented one.
Most calls start with a cold room over the garage, a hot upstairs in July or an attic nobody's looked at in years. Attics are good at hiding things, so I want to see what's already up there before any foam goes on, because foam sprayed over wet or dirty insulation just seals the problem in.
The price moves with the foam type, with closed cell costing more than open cell, and with how much area we cover and how thick it goes on. The schedule turns on the weather, since temperature and humidity change how foam cures, and on when you can be out of the house. Your written estimate spells out what we'd do, in what order and why. We're fully licensed and insured, and Montana now requires every construction contractor to be licensed with the state Department of Labor & Industry, so it's fair to ask anyone you're considering.
- We spray open cell or closed cell foam on roof decks, walls, rim joists and crawl spaces.
- Old insulation that's soaked or full of droppings comes out first, so the foam doesn't seal it in.
- We cover your stored things, protect the rooms we walk through and clean up when we leave.
What happens when you call us about spray foam?
Here's how a spray foam job runs with us, from your first call to the walk-through at the end. I'm the one who comes out to look, and our crew does the spraying.
Call or send us the form
Call (406) 414-0411 or send the form with the area you want insulated and when you'd like it done, and we'll get back to you to set up a visit. If you know your house's age or how many inches of insulation are already up there, tell us.
I come look at the space
I look at the attic, walls, crawl space or basement myself and note anything that has to be fixed first, like gaps around can lights or wet insulation. That way the estimate covers the whole job, not just the foam.
You get a written estimate
The estimate says which foam goes where, what we'd do and in what order, so you see the price before anything is scheduled. If something has to be fixed before the foam goes on, it's listed there with the reason.
We spray, clean up, walk through
A small crew led by our lead installer does the work, and I'm on most jobs too. When it's done and you're back inside, we walk through it with you.
What spray foam looks like on the job

(406) 414-0411Spray foam questions we hear in Bozeman
These are the questions Bozeman homeowners ask most before a spray foam job. Most come down to which foam, what it costs and how long you're out of the house.
How much does spray foam insulation cost in Bozeman?
Spray foam covering 1,000 square feet at 3 inches thick in Bozeman usually costs about $2,000 to $4,500 per job. That's the going rate in the area, not our price. We give you a written price for your own job once we've looked at the space.
What is the best way to choose between open cell and closed cell spray foam in Bozeman?
One building science guide says closed cell foam is preferred in cold climates, and that open cell can work with a vapor retarder on the inside to control condensation. For foam under the roof deck, the same guide says only closed cell should be used in climate zones 5 and higher. Ask us how that applies to your house, and we'll go through it part by part.
How long does it take before we can go back in the house after spray foam?
Most foam makers say to stay out while the foam goes on and for a while after, and some say 24 hours for professional systems. That wait, called the re-entry time, varies by product, so we tell you the time for the foam we're using and plan it with you before the job, pets included.
Is spray foam insulation flammable once it cures?
Yes, cured foam will burn if it meets a direct flame. Welding, torch cutting and flame heaters near the foam should wait until drywall or another ignition barrier covers it.
Can spray foam make my house too airtight for my furnace or water heater?
It can, if those appliances burn fuel in the space we're sealing. Making a house tighter can limit fresh air, and areas with fuel-burning appliances may need extra air exchange to keep combustion gases from building up, which is worth raising with an HVAC design professional.
How do I get a permit question answered in Bozeman?
Call the city's Building Division at (406) 582-2375 ext. 1, which takes questions on permits, plans and inspections. If a bigger remodel is in the works, applications submitted on and after January 1, 2027 have to be designed under a newer set of building codes, so it's worth asking early.
