Insulation contractor services in Missoula, MT
Summit Missoula Spray Foam Insulation is an insulation contractor in Missoula, MT, handling 16 kinds of work, from a drafty attic to cold floors over a crawl space. The price depends mostly on what's already in your house: how many inches are up there, whether old material has to come out, how many gaps need sealing and whether foam or blown-in suits the space. The schedule depends on the same prep, plus the size of the space and how easy it is to reach. I'll put your own figure on a free written estimate that explains each step and why it's there.
Spray foam insulation
Spray foam goes on as a liquid and expands into the gaps, so it seals air and insulates in one pass. That suits rooflines, basement walls and tight, odd-shaped spots.
Attic insulation
Hot upstairs in summer and cold all winter? We seal the attic's leaks first, then bring the insulation up to an even depth, edges included.
Blown-in insulation
We add blown-in insulation, loose fill we send through a hose, to attics and closed wall cavities. It's a good fit for topping up thin coverage without tearing anything out.
Home insulation
Not sure where the cold is coming from? I look over the attic, walls, crawl space and basement, and then we fix the weak spots in the right order.
Insulation removal
When old insulation is soaked, matted or full of droppings, we pull it out and clean up first, because new material laid on top just hides the problem.
Crawl space insulation
Cold floors usually start below them. We insulate the crawl space so the rooms above stay warmer through a Missoula winter.
Wall insulation
Older houses often have walls with little or nothing in them. We insulate those cavities so the rooms along outside walls stop feeling drafty.
Air sealing services
Air sealing is closing the gaps around pipes, wires, lights and the attic hatch before insulating, so warm air stays in the house instead of slipping out.
Basement insulation
We insulate basement walls so a finished room, or one you plan to finish, stays comfortable and the floor above loses its chill.
Closed-cell foam insulation
Closed-cell foam is a dense foam that also blocks moisture, so we use it where dampness is a concern, like crawl spaces, basement walls and rooflines.
Open-cell foam insulation
Open-cell foam is softer and lighter. It fills odd-shaped cavities and quiets noise between rooms, so it suits interior walls and attic rooflines that stay dry.
Commercial insulation
Own a shop or a small office? We insulate small commercial buildings the same way we do houses, sealing first, and we work out timing around when you're open.
Crawl space vapor barrier
When the crawl space smells musty, we cover the dirt with a heavy plastic vapor barrier so ground moisture stays out of your framing.
Vapor barrier installation
We install vapor barriers on the warm side of walls and ceilings, so moist indoor air doesn't reach cold framing and condense inside the wall over the winter.
Attic air sealing
Before any insulation goes up, we seal the attic's gaps around can lights, pipes, wires and the hatch, so the new layer isn't fighting a draft.
Retrofit insulation
Retrofit work adds insulation to a house that's already lived in. We work around finished rooms, old wiring and the framing quirks I learned to spot building houses.
A former framer insulating Missoula homes
Summit Missoula Spray Foam Insulation is an insulation contractor in Missoula that we started in 2023, after I'd spent years framing houses and then learned this trade working for an established installer. We're licensed and fully insured. Most of our calls come from people in older houses who are tired of cold rooms and high heating bills, plus a few small business owners, and we cover 16 kinds of insulation work for them. You can read more about us and how we work.
About usWhy hire us to insulate your Missoula home
You deal with the owner throughout
You work with me from the first look at your attic to the final walkthrough. The person who sized up your house is the one working alongside the crew on install day.
We check the whole space first
Before I quote, I look over the whole attic, crawl space or basement, so damp spots, old wiring or suspect insulation get dealt with before anything covers them. That way you don't pay to hide a problem.
Planned by someone who's framed houses
Years of framing taught me what sits behind the drywall and under the floor. We plan each job around how your house was actually built instead of running the same routine on every home.
Plain answers about your own house
I show you what I find and explain it in plain words, and I take as long as you need with questions. You'll know why every step on the estimate is there before you decide anything.

Insulation work, up close
From your first call to the final walkthrough
Call or send a request
Call us or send a request with a few lines about what's bothering you, whether that's a cold back bedroom, a hot upstairs or the room over the garage. We get back to you within one business day to set a time for me to come out.
Walk the house with me
I go through the attic, walls, crawl space or basement with you and point out what I see, like how many inches are already up there and where air is getting in. Then I send a free written estimate that explains each step and why it's there, with no obligation.
Prep, seal, then insulate
Our crew and I take care of anything that has to come first, like pulling out soaked insulation. Then we seal the gaps around pipes, wires and the hatch, and insulate, keeping the eave vents clear so the attic can still breathe and running full depth out to the edges.
Clean up and walk through
When the insulation's in, we clean up the attic access and anywhere we walked through your house. Then you and I walk through the finished work together, so you can see what was done and where it went, and ask anything that's still on your mind.

Insulation questions from Missoula homeowners
How much does attic insulation cost in Missoula?
It depends on what I find up there, so your price comes on a free written estimate after I've looked. In older houses, the big differences come from a low or cramped attic that's slow to work in, lots of gaps to seal around old wiring and chimneys, and old material that has to come out first.
Is spray foam worth the extra cost compared to blown-in insulation?
For a plain attic floor, usually not, because sealing the gaps and topping up blown-in insulation does the job for less. Foam costs more because it seals air and insulates at the same time, and it's worth that when your ductwork runs through the attic and needs to sit inside the warm part of the house.
How long will an insulation crew be in my attic?
That depends on the size of the attic, how much old material has to come out and how many gaps need sealing, so I talk through timing with you when I come out. Removal and repairs add time, and when the work needs a permit, we have it in hand before we start.
Is your insulation company licensed and insured in Missoula?
Yes, we're licensed and fully insured. Ask me about either one when I'm out for the estimate, and I'm happy to go over it with you.
Do we have to leave the house while you install insulation?
For blown-in insulation and air sealing, you can usually stay home while we work. Spray foam is different, because it comes with re-entry time, the hours before you, the kids and the pets can go back inside. I go over that with you before the job day so you can plan where everyone will stay.
Do you guarantee your insulation work?
Your satisfaction, guaranteed. We finish with a walkthrough together, so you can see what we did and point out anything you're unsure about while we're still there.
Should old insulation be removed before adding new insulation in my attic?
If the old insulation is soaked, moldy or full of rodent droppings, yes, it should come out first, because covering it leaves the moisture and smell right where they are. If it's dry and just thin, we usually leave it in place and add on top after sealing the gaps, which keeps the cost down.
Do I need a permit to insulate my house in Missoula?
It depends on the job, and the city's list of work that needs a permit doesn't settle insulation either way, so we check before we start. Inside city limits, that's the City of Missoula, which asks people to call 406-552-6630 before starting any work. Outside city limits, it's the Missoula County Building Division. If the job means replacing or moving a bath fan vent, the city requires a mechanical permit for that part, and we tell you what they say and take care of any permit the work needs.
