I highly recommend Bozeman Insulation. After calling 3 of the other big guys in town, and not even getting an estimate, Jesse took care of me. Very prompt on the estimating and bid process. He works with my project schedules and his team gets it done. He has done my last 10 projects flawlessly.

Cameron Richards★★★★★2 years ago

We gave Jesse and crew a test run on a spray foam insulation project we had going. They delivered at a fair price, with outstanding communication, turn around time and quality. Only company we will use moving forwards on any insulating projects. We have referred them to 3 others who have had the same experience now, foam and batting, these guys deliver everytime.

Bozeman Insulation took care of our project quickly and professionally... I needed the old insulation removed quickly to do a full rewire and they did this with little notice...when the rewire was complete, they came back out and were very flexible with our requests to get our home fully insulated for the cold weather again. They respected our home and did a very professional job...and I thought the price was very reasonable as well! Also, they helped with photos so I could put in for a rebate...I highly recommend them.

I'm an owner builder and had done a partial ceiling insulation job that just wasnt meeting the desired performance. I called True North and Lonn got back in touch promptly, we did a walk through of the house that afternoon and schedules aligned and the crew showed up to knock out the work the next day! The team was professional and good to work with. The job was well done.

Frank Palestini★★★★★a year ago

I recently had my garage insulated by Lon and the team at True North Spray Foam, and I couldn't be more pleased with the results. They were punctual, professional, courteous, and maintained a clean work environment throughout the entire process. Lon ensured that his team delivered the highest quality work, and the final product exceeded all my expectations. Highly recommended!

Todd, Rachele, and the crew did a splendid job on our new building. They sprayed extra foam in places where the need was greater. They were dependable, thorough, neat, and they helped me find ways to save some money. My building stays toasty on these chilly winter days.

Michael Mcbride★★★★★10 months ago

Todd and crew were great people to work with. They did a great job and I would highly recomend them for any insulation project. I look forward to working with them in the future.

Robert Lokker★★★★★a year ago

Thank you Todd and company for working with us (First Baptist Church of Darby) at our under construction Crosswalk Ministry Center in "downtown" Darby. First Todd came and personally met with our leadership and explained the benefits and process involved with the spray foam insulation. We thought it would be out of our price range but he worked with us on a good bid - including a discount for non-profits. Then he went out of his way in fitting the spray work into our tight schedule - we had a big volunteer work crew coming out and had to to fit Todd's work in between the just finished roof, the inspectors framing and electrical approval and the crews arrival. And just in time they got it done - first and second floor exterior walls and the entire inside roof ceiling. A big job and well done - thank you Todd and crew!

This company is probably the best company I have ever seen operate. Many recommended them but you can’t say enough. They operated like a well oiled military fire-team, fast efficient and just awesome. Owner Eric came, sprayed, answered all questions. Kept the crew on their toes and it was non stop from the moment they arrived. If there was a 10 for a rating they deserve a 20 Eric, thank you. I almost thought there were no companies left in America worthy of a 5. Awesome job thanks

Roger and the guys at Helena Insulation were great to work with. I had them spray closed cell foam in a 40 x 28 pole building. They showed up when they said they would and did a great job installing. They took the time to explain things to me and checked the depth all the way thru the process. They did a great job of protecting everything as well as a great clean up when they were done. Awesome job guys! Thanks.

Friendly and professional! Steve was such a delight, and took care of the problem so fast I didn't know what to do with the rest of my day. :) I will 100% be contacting them again, and recommending them to anyone I know who needs insulation work done. Thanks Steve!

Doug Hoff★★★★★10 months ago

Following install of corebond and batt insulation in my home under construction, we heated the place up with a portable heater overnight. the next day, we turned it off, and the temp held all day long. Great job, Helena Insulation!

Shelly Constant★★★★★a year ago

I knew spray foam was a superior option for insulation, but until I came across this web site, I didn’t know about open cell vs closed cell.. The closed cell option would be preferred, because, while also providing insulation from the outside elements, I hadn’t even considered how it also blocks out moisture and prevents mold growth and it even has sound proofing benefits. I’m at the very start of this project, but I already feel like I have a better understanding and I won’t hesitate to call them again, in the very near future, when I’m ready. They will be my first choice.

Alissa Rooks★★★★★a year ago

I recently had the pleasure of working with Bozeman Spray Foam Insulation Company, and I couldn't be more impressed with their professionalism and quality of work. From start to finish, the team was incredibly knowledgeable and attentive to my needs. They provided a thorough assessment of my home's insulation needs and offered a solution that fit within my budget. The installation process was seamless, and the results exceeded my expectations. Not only has my home become more energy-efficient, but I've also noticed a significant improvement in comfort. I highly recommend Bozeman Spray Foam Insulation Company to anyone looking for top-notch insulation services.

Frequently Asked Questions — Spray Foam Insulation in Great Falls

Is spray foam insulation worth the cost?
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic costs $2,000–$6,000. Most homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor?
Look for contractors who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
