Your attic is where most homes lose heat in a Missoula winter. Proper attic insulation keeps warmth inside and reduces what your furnace has to work through.

Thin or patchy insulation up top? Blown-in material fills around joists and odd corners that batts can't reach, bringing your home up to where it should be.

Every part of your home - attic, walls, crawl space, basement - works together. A full home insulation assessment finds the gaps costing you money every month.

Old, wet, or pest-damaged insulation makes things worse, not better. Safe removal clears the way for clean, effective new material.

Cold floors in winter are usually a crawl space problem. Insulating the walls and rim joists stops cold air from sitting under your living space all winter.

Walls with no insulation or compressed old batts let heat walk right out. Retrofit wall insulation keeps your rooms comfortable without major renovation.

Insulation slows heat loss, but air sealing stops it. Sealing gaps around fixtures, pipes, and framing is the step most contractors skip - we don't.
Learn MoreReach out by phone or through the contact form. We will ask a few quick questions - your home's age, what areas concern you, and any specific problems you have noticed. We respond within 1 business day and can usually schedule your estimate within a few days after that.
A technician visits your home, walks the attic, crawl space, or any area you want looked at, and measures what is actually there. You will get a written estimate that breaks down the cost by area and explains what type of insulation is recommended for each space. No pressure to move forward on the spot.
Our crew handles the full job - air sealing, prep, and installation - and cleans up before they leave. Most residential jobs wrap up in a single day. We walk you through the finished work, leave you with documentation for any rebates or tax credits, and check back in if anything comes up.
We hold a valid Montana contractor's license issued by the Montana Department of Labor and Industry and carry full liability insurance on every project. If something goes wrong, you have real recourse - not just a handshake.
Every estimate is free and done in person - not guessed over the phone. You get a written quote that breaks down cost by area before any commitment is made, so you know exactly what you are paying for.
We live and work here. We know the University District bungalows, the South Hills hillside homes, and the crawl space issues that come with Missoula's older housing stock. Local knowledge shows up in the quality of the work.
We reply within 1 business day and can typically schedule your estimate within the same week. When a Montana winter is on the way, that turnaround matters.

“I called on a Thursday, had an estimate by Monday, and the crew finished the attic blown-in job the following week. The difference in how the upstairs rooms hold heat is noticeable - my furnace isn't running every 20 minutes anymore.”
Derek M., Missoula — Attic Insulation
“Our crawl space was a disaster - no insulation and moisture issues. They came out, explained what they found in plain terms, and gave us a written quote the same day. The spray foam they put in the rim joists has made our floors warmer than they've ever been.”
Sarah K., Hamilton — Crawl Space Insulation
“We had terrible smoke infiltration last fall during wildfire season. After the air sealing and attic insulation work, we could actually tell the difference - the house stayed much tighter when the smoke was bad outside. Worth every dollar.”
Tom R., Kalispell — Air Sealing Services
We respond within 1 business day - no waiting around for a callback that never comes. There is no obligation to move forward after the estimate. After you submit, someone from our office will call to schedule a free on-site visit where we measure what is actually there and give you a written quote.

If you can see your attic floor joists above the insulation, you are almost certainly below the recommended depth for Missoula's climate zone. The Department of Energy recommends 14 to 18 inches of blown-in material for attics in this region - most older Montana homes fall well short of that.
Yes. When outside air finds its way in through attic gaps and crawl space cracks, smoke comes with it. A properly air-sealed home gives you real control over what gets inside during smoke events - something Missoula homeowners deal with every late summer and fall.
Closed-cell foam is rigid, dense, and blocks moisture - right for crawl spaces, rim joists, and anywhere water intrusion is a concern. Open-cell foam is softer and better suited for interior walls and attic spaces where moisture is not an issue. Your contractor should recommend based on what is actually in your home.
Homes built before the 1980s were often built with minimal insulation by today's standards - or none at all in crawl spaces and rim joists. That insulation has also compressed over decades, losing much of the effectiveness it once had.
Under the Inflation Reduction Act, homeowners can claim a tax credit worth up to 30 percent of qualifying insulation materials, up to $1,200 per year. Your contractor should be able to tell you which products qualify, and you will need to keep the product documentation to file with your return. Learn more at the IRS Energy Efficient Home Improvement Credit page.
For most standard attic or crawl space insulation jobs, a permit is not required in Missoula. If the work involves structural changes or is part of a larger renovation, a permit may be needed. A licensed contractor will know the current requirements and handle any paperwork on your behalf.

If your existing insulation is wet, moldy, or has been disturbed by rodents, it needs to come out before new material goes in. Adding insulation on top of damaged material does not fix the problem - it covers it.
Air sealing plugs the gaps around light fixtures, plumbing pipes, and framing where conditioned air escapes. Insulation slows heat transfer; air sealing stops air movement. Both are needed for the best result.
Ask for the contractor's Montana license number and verify it with the Montana Department of Labor and Industry. A reputable contractor will give it to you without hesitation.

Missoula is a city of about 75,000 people built in a mountain valley where the Clark Fork River runs through the middle of town. The University of Montana anchors the city's identity, and neighborhoods like the University District, the South Hills, and the Rattlesnake area have their own distinct character. About half of Missoula's homes were built before 1970 - craftsman bungalows, small ranch homes, and wood-frame two-stories that have been through decades of hard Montana winters.
The valley geography creates real challenges for homeowners. Cold air pools on the valley floor during winter inversions, which means prolonged cold snaps that push heat out of any gap in your building envelope. The same bowl shape that traps cold air in January also traps wildfire smoke in late summer - and the Rattlesnake National Recreation Area and the forests surrounding Missoula make that smoke a regular seasonal presence. Homes with gaps in the attic and crawl space let that outdoor air in constantly - whether the problem is cold in February or smoke in September.
Missoula's housing stock - heavy with pre-1980 construction - is well-suited to the kind of retrofit insulation and air sealing work we do. Whether you are in an older bungalow near the University District, a hillside home in the South Hills, or a newer place out near Grant Creek, we serve homeowners all across Missoula and know what local conditions do to homes here. Call us for a free estimate - most Missoula projects are scheduled within the same week.
