Very thankful I chose this company! Layne was honest and to the point during the inspection, and extremely transparent with the estimate. I work in construction myself, so I really appreciated the professionalism and straightforward approach. He was also able to provide the rebate instantly—something no other company could do. Highly recommend!

365 Insulation transformed our attic from drafty and cold into a cozy, efficient living space. The team showed up on time, took before and after photos, explained exactly what they were doing, and left our house spotless when they finished. They gave us the best quote of several we requested and followed through with quality workmanship. If you’re looking for insulation that actually makes your home feel warmer and your utilities drop, I’d recommend 365 Insulation without hesitation!!! Thank you so much TEAM 365 INSULATION!!!

I recently hired 365 LLC to insulate my garage attic, and I couldn’t be happier with the results. Daniel was professional, knowledgeable, and very easy to work with from start to finish. He took the time to explain the process, recommended the best insulation for my space, and made sure everything was done neatly and efficiently. The difference in temperature is noticeable right away 😄😉 and I’m sure it’ll help with energy savings too. The cleanup was spotless, and the whole job was completed on schedule. I highly recommend Daniel and 365 LLC to anyone looking for high-quality insulation work. Excellent service, great communication, and top-notch workmanship!

Mike Ysbrand★★★★★2 years ago

Had Dan & his crew insulate our garage attic space. Great communication, prompt, and very fast. Took pictures of the entire process and then had me get up in the space to check it before they left. Super nice guys, transparent with everything, would recommend them without hesitation to anyone needing their service. Thanks again Dan!

Great experience all around from Luke who helped us decide which insulation route to take and Harley and the team did a fantastic and professional job insulating. In addition they noticed our bathroom fan vent going into the attic and not the roof and were able to take care of that for us so we’re not getting moisture into the new insulation. Great job USA team.

breezeymom★★★★★4 months ago

Both my neighbor and I had crews at our houses, one was just foaming the gaps at vents and pipes, as well as additional insulation on top of what I had; the other was an extraction due to critters, sanitizing and a whole new layer of insulation. They arrived ON-TIME, friendly and explained everything they were doing. My project was complete in 2-1/2 hours; my neighbor an additional hour later. 2 crews: roughly 4 hrs; both jobs complete!!

From the sales to the actual service done everything was well done. No sales pressure. The work was completed in a timely manner. Technicians were very professional, knowledgeable, and efficient and very friendly. Highly recommend this company. We had both sides of our town home done and they did an amazing job sealing the areas that needed it and repairing vents and replenishing the needed insulation.

Brandon and his team were great to work with. Had reached out for a job towards the end of the day, not expecting to have him out for a few days but came even after a long day! He was patient while I waited for another company.. safe to say Brandon and team provided better products (R-Value) at a better rate! The team showed up on installation day, and knocked the job out. Cleaned up after themselves and put everything back. Definitely will be using again, highly recommend!!

Great experience all around. Emailed Brandon off his website with a question about insulating our attic and fixing a few other things that were not done correctly the first time. He called me soon after, came out on a weekend to check it out and give me a quote. Fit me into his schedule shortly after and now our house is better than what it should have been to start with.

We had our roof replaced and hired Travis to install some Spray Foam insulation. His was the lowest bid of the three estimates, but that wasn't the main reason we hired him. When he stopped by to give his estimate, he was knowledgeable, personable, and I trusted him. After reading all of the positive reviews, it was a no brainer to hire him. Right on time, neat, finished in a timely manner, and cleaned up well. Highly recommend Travis. You won't be disappointed.

I stop by while they were insulting our neighbors walls and ask if they could insulted our garage attic! They give us a great price and stop over later in the day and did ours. They cleaned up and did a great job! Thanks jimmie & Anita

L Z★★★★★a month ago

I thought Travis and his guy were honestly wonderful. Travis came out for a quote and listened to my concerns and really helped me out in pricing and a wonderful job. It sucked they were booked out so far but it gave me time to finish what I needed without feeling rushed to get the job done. He gave feedback too which helped every step of the way. For a 1200 sq foot 4.5 feet tall crawl space, it took almost an hour and a half. I took the whole day off work thinking it would be that long, instead I got to go in and work half a day because of how fast he is and how nice it looks! My crawlspace is held up by cinder blocks in the middle so he even helped seal around the edges because he knew vapor barrier tape wouldn't do the job. He and the other guy did wonderful going above and beyond letting me know of other areas they had to insulate before spray foaming. Grade A from this team!

We recently worked with SNAP Construction after they reached out to inform us about rebate programs available through local energy companies, the federal government, and other sources to help improve home insulation. Layne came to our home and did an excellent job explaining the different rebate options, financing plans, and the entire insulation process. He made everything easy to understand and stress-free. Alexis and Tarik handled the actual work. They removed all of our old attic insulation, sealed any openings, and installed new insulation that helps repel mice and bugs. The next day, they returned to insulate the walls. They arrived on time, were respectful of our home and furnishings, and left everything clean when they were done. Overall, I’m very satisfied with the quality of work and professionalism from SNAP Construction. Highly recommend!

Mary Anderson★★★★★2 weeks ago

Snap Construction did a new roof and insulation for me this summer (2025). I’m happy I hired them and appreciated their emphasis on customer service. When determining if a company is reliable and trustworthy, the real test is when things go south. Any company can have great customer service when a project goes well. But not many companies hang in during the bad times. My project hit bad times (not the fault of the Snap team), and it showed just how good Snap Construction really is. My house is over one-hundred years old and packed with surprises and quirks. I hired Snap for a new roof and insulation. The end-result is fantastic, but there were unforeseen issues that made the process far more difficult than anyone wanted. Through these difficulties, I discovered that Snap Construction really is outstanding in customer service and problem-solving. They stuck with me no matter what came up. Many companies would have distanced themselves from me and the project. It is human nature to avoid difficult things. Other companies may have tried to cut their losses by backing out when the going got tough. But Snap and their crew never did. As the project dragged on, they never fatigued of answering my texts or addressing hurdles. I remember one evening in particular when I worried about a potentially exposed rafter. They answered my text (after hours) and showed up to ensure the roof was secure. Although the problems encountered were no fun, it never became a true nightmare because the Snap crew and I remained teammates. We each knew the other was acting honestly and in the best interest of the project. I saw first-hand that the Snap team was worthy of the trust I put in them. In addition to addressing the unforseen problems, Snap also performed well on all the other things that matter on a project. Their insulation team did a great job discussing a cold vs hot roof and what insulation would work best in my attic. And they made getting the rebate easy. They presented great options for shingles, and they contacted the manufacturer to answer my questions about how much sunlight the shingles reflected (for heat management in my upstairs). I saw Snap is a place of mutual respect, shown both to their customers and to fellow Snap employees. Teams have the best results when they work well together - so seeing the members of the Snap team work well with each other reassured me that the team was performing at their best. All crew members on site were kind to me and got along well with each other (which is uplifting to see). I appreciated that Snap does both roofing and insulation. Due to the nature of my project, it made sense to do these projects together. It was challenging to find a roof company that was also experienced in insulation, so I was happy to find that Snap does both. I even met at my site with both the roofing and insulation reps simultaneously when planning the project. I would like to especially thank Tim, Layne, Randy, and Josh for sticking it out and getting the project to completion.

We bought a home and during the inspection, we realized we had mold in our attic. We called several companies and looked at various reviews. We ended up using Affordable Insulation and it was positive experience. They communicated well, showed up when they said they would and completed the work in a timely manner. I have since recommended them to my family and others.

If you need something insulated this is the company you want. We have a very old home that's had 3 different additions from three different time periods. It was a mess up there! Justin with Gunner Insulation definitely came through and did an amazing job. Great communication from the tech (Justin) and from the office. The job was done well and I could tell the difference after day one! On top of great customer service and doing a quality job they're pricing was beyond reasonable. I am a do-it-yourself guy and after crunching the numbers this just made way more sense to have the pros do it and get it done quick and right. Definitely give these guys a call, I'll be referring them to all my other customers in the future.

Our house was built in 1947 and we had a big problem with ice dams every year. So a few years ago, I started getting estimates from insulation companies. It never felt right so I continued to delay it. One recent fall day, I saw a Brian's insulation truck in my neighborhood and decided to follow up with a call and was impressed with the quiet competence of one of the owners that came out to estimate the project. We had the new insulation installed this week and the house is definitely warmer. The team of installers blew in the pink insulation, repaired holes in the attic and sealed all of the areas around the ceiling light fixtures. They were professionals in every way. very impressive, In addition, the office manager submitted a rebate for me to Centerpoint Energy. I am delighted with my new insulated attic and the price was better than I expected. For all these reasons, I highly recommend this family-run company - Brian's Insulation. Here are some photos of the tube carrying the pink stuff into the attic from the front door.

It was great working with them for our project.

They re-insulated our crawl space under our dining room. From the appointment with Jon to getting an estimate and Uriah and his team to install was smooth and seamless. Jon was very responsive and answered any questions we had quickly. He also provided options for the work if cost was a concern. We felt their price was fair and reasonable and proceeded with the full crawl space. Uriah and one other came to install the insulation. I didn’t get his partners name, but they worked quickly and efficiently. Finished everything in a couple of hours and there was virtually no mess left. We had concerns about the dust that might be created by removing the old insulation, but they sealed the opening and there was no dust at all. Bagged up all of the old insulation and sprayed the new. We would recommend Koala for any of your insulation needs! They are also one of the few insulation installers who do crawl spaces on top of everything else.

Johnathon Simmonds★★★★★a month ago

Seldom do I leave reviews because it takes a lot for us to feel obliged to share an experience at a high rating. That being said - the team at Century Insulation were incredible. We began inquiring on their insulation services as early as November 2021, and again in fall 2023 as we planned out how we wanted to renovate our upstairs, and lastly in 2024 debating if we would keep what we had and improve it, or completely remove and start from scratch. We were trying to decide between traditional fiberglass or taking the modern approach - closed cell spray foam. In 2025, we made the leap to proceed forward. We renovated our Attic space and it required a full demo and insulation project to bring our 1950s era home up to modern standards. Our R value prior was next to nothing - 2 inches of fiberglass from the 1950s or 60s that had degraded in our one and a half story home. Days were often spent being over 100 degrees in our attic. My wife and I were thoroughly impressed by the team’s attention to detail and authenticity to delivering value and quality. Now when we’re in our attic, it’s cooler than the downstairs which is an achievement in a one and a half story home. A handful of shoutouts to the crew: Crystal in the office went above and beyond in scheduling the team out and working with our project timetable. She also advocated for the offered rebates and helped us achieve a very positive outcome. Ryan was flexible and made several visits to quote us and answer any and all questions in a timely manner. He was flexible with our budget and helped us achieve a quote that fit with our project. Jesse as the business owner made himself available for all relevant concerns around permitting, HVAC questions, and how we could get the best bang for the buck being spent with the R-Value we were looking to achieve. He also helped us pass inspection and in speedy fashion adding a paint layer required by our city. I enjoyed working with each of them and their crew that came out. Century insulation is a down to earth group of folks looking to do business with good people. People want to buy from good people - and these are good people. I would gladly partner with them again on future projects and have gladly given their info to others we know. Give them a chance if you’re looking to do an insulation project, you’ll be happy you did.

It’s been a few months since we had Choice Foam out to insulate our attic. After meeting with Anthony, he provided us a bid promptly. The price was right. He was able to fit us in before it got too cold and they finished the job early. Anthony and his crew did an excellent job. We’ve noticed a big difference in the warmth of our house and our heating bill has dropped significantly from last year. These guys are great and I’m so glad we found someone local to do the job!

I had the privilege of doing business with Choice Foam, I say this because too many companies make lofty promises and do keep them. That was NOT my experience with Choice Foam Insulation. Everything went exactly as planned, from the initial quote to the time line to the installation, was spot on. The team was very professional and made sure that things were done right. I can appreciate when a company takes pride and ownership of a project, not just treating it like another job. They treated me and my home with the utmost respect. Over the past winter months, we have already seen significant savings in our heating bills! I am definitely recommending to my friends and family. Thanks again Choice Foam Insulation.

Frequently Asked Questions — Spray Foam Insulation in Minneapolis

These are the questions Minneapolis homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 40% typical energy savings. Compare the 22 verified Minneapolis contractors above for exact quotes.

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 in Minneapolis, MN?▼
In Minneapolis, MN and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. 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 in Minneapolis costs $2,000–$6,000. Most Minneapolis 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 in Minneapolis, MN?▼
When searching for a spray foam contractor in Minneapolis, MN, look for ones 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 Minneapolis 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 in Minneapolis 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.
