Spray foam insulation in Missoula MT - drafts sealed and rooms that hold heat
Cold rooms, drafty floors and a heating bill that climbs every winter? We seal and insulate in one pass so the heat stays inside.
Is spray foam the right insulation for your Missoula house?
Spray foam insulation is foam sprayed onto your attic, walls or crawl space that expands into every gap, so it stops drafts and slows heat loss at the same time, and Summit Missoula Spray Foam Insulation does this work on houses across Missoula, MT.
Most people who call me live in an older house with a cold room over the garage, a drafty upstairs or a power bill that jumps every January, and they've heard foam is the fix. Sometimes it is, and sometimes sealing the gaps and topping up with blown-in insulation, loose fill blown through a hose, does the job for less, so I'll tell you which way I'd go and why. Foam earns its higher price when your ductwork runs through the attic, because it seals the air around everything up there while it insulates. The price turns on how many square feet we cover, which foam fits the spot and how deep it goes, and whether old insulation has to come out first, while the schedule mostly turns on finding a stretch when your house can sit empty. When I come out, I'll put your own numbers on all of that.

Spray foam and attic insulation work
How we handle spray foam insulation
We set the spray date with you well ahead, so the house can be empty, other crews can be scheduled before or after us, and you have time to sort out somewhere to stay. Before any foam goes on, we take care of whatever has to come first, like pulling out insulation that's been soaked or filled with droppings, because foam sprayed over a problem just seals it in. Then we cover what needs protecting and spray the foam so it fills the gaps around pipes, lights and the hatch and runs just as deep at the edges as in the middle, since thin edges are where the cold usually gets in. We keep the eave vents clear wherever the attic still needs to breathe, trim and clean up, and I walk the finished work with you once you're home.
Foam isn't always the whole answer, and on plenty of older houses I'd spray only the spots that need it, like a room over the garage, and cover the rest another way. Most often that means sealing the leaks and laying blown-in insulation across the attic floor, and our attic insulation work brings the whole space up together.
Why Missoula homeowners call us for spray foam
I come out to every job
I come out to look at each job myself, and I work alongside our crew on the install. That means the person who crawled through your attic with you is there when the foam goes on and remembers what you talked about.
Framing years before insulation
I spent years framing houses, then learned insulation working for an established installer before we started our own company in 2023. Knowing how a house goes together, the way a framer knows where the studs land before the drywall goes up, lets me tell you what's behind a wall before we open anything.
Licensed and fully insured, every job
We're licensed and fully insured. Montana now requires all construction contractors to be licensed with the Montana Department of Labor & Industry, so it's a fair thing to ask any crew you're comparing.
Used to older Missoula houses
We're based in Missoula and work in Missoula, Orchard Homes and the cities around them, inside and outside city limits. Most of our calls come from older houses with cold rooms and high heating bills, so the tight attics and odd framing up there don't surprise me.
On a foam job, getting the order right matters most, because whatever's left under the foam stays there. If you'd like your house looked at, call or send us a request and I'll come take a look.

What happens after you call about spray foam in Missoula?
Call or send a request
Call (406) 317-4027 or use the form, and we'll get back to you to set a time for me to come out. It helps to mention which months you could be away from the house for a stretch.
I walk the house with you
I go through the attic, walls, crawl space or basement with you and explain what I find as we go. Then you get a written estimate that lays out each step, why it's there and the price for your house.
We seal, spray and clean up
With the house empty on the date we picked, we take care of anything that has to come first, then seal and insulate. We clean up before you come back, and I'll have told you ahead of time how long the foam we used needs before you return.
Walk through the finished work
Once you're home, we walk through the finished work together so you can see what we did and ask about anything. We stand behind it with our one promise, "Your satisfaction, guaranteed."
Spray foam insulation questions in Missoula
Should I use open cell or closed cell spray foam in Missoula?
Use closed cell foam wherever your house needs a vapor barrier, because it's the only kind that acts as one, and it also insulates more per inch. The city lists Missoula as climate zone 6B, and one foam maker's design note says open cell is typically used in warmer zones but can work in zone 6 when an approved vapor retarder, a layer that slows moisture, is added toward the inside of the house. So the first question is where your house needs that barrier, and I'll show you on the visit.
How much does spray foam insulation cost in Missoula?
Spray foam insulation in Missoula usually costs about $2 to $5 per square foot, and that's the going rate around here, not a quote from us. Open cell foam tends to cost less in material but takes more of it to reach the same level, so the material price alone may not tell you what the whole job costs. Your estimate shows the price for your square footage and the foam your house needs.
How long do we have to stay out of the house after spray foam insulation?
Plan on being out the whole time we spray, plus the wait the foam maker gives, which some makers set at 24 hours after professional high pressure spray foam, though it varies by product. The EPA's guidance, now on archived pages, says nobody should be in the building during spraying, since breathing the chemicals can cause asthma, lung damage and other breathing problems and can irritate skin and eyes. That goes for kids and pets too, and I'll give you the re-entry time, the point when you can come back, for the exact foam we're using.
What is the best time of year to get spray foam in Missoula?
The best time is when the temperature and humidity fit what the foam maker calls for, because EPA guidance says both play a critical role in how spray foam cures. We look at that before we book, along with the months you can be away from home.
Who do I call about a spray foam insulation permit in Missoula?
Inside city limits, building work goes through the City of Missoula Building Division, and outside the city's jurisdiction it's the Missoula County Building Division. For each job we check with whichever office covers your house, tell you what they say and take care of any permit the work needs before we start.
What should an electrician or plumber know about spray foam in my walls?
Tell them not to heat or grind the foam, because EPA guidance warns that doing so can give off toxic emissions. It's easier to warn them when you know where the foam is, so I'll show you every spot we sprayed on the walk-through.
Insulation in Missoula and nearby areas
Work that goes with spray foam insulation
Attic insulation
When foam only makes sense in part of the house, the rest of your attic still needs even coverage out to the edges where cold gets in.
Blown-in insulation
Loose fill blown over sealed gaps is often the cheaper way to warm an attic, and it's worth weighing against foam whenever your ductwork isn't up there.
