Spray Foam Insulation in Ann Arbor, MI

Niko does great work at competitive prices. He did closed cell spray foam in several places plus blown-in cellulose in our attic. I asked a lot of questions before the job, and he was very patient and took the time to explain everything. Great communicator. We are happy with the result. 100% recommend.

I can't recommend these guys enough, they did an awesome job. Our house is about 150 years old, has had multiple additions, and was a neglected rental for many years so no project is ever straightforward. Niko the owner came out and happily went into both attics to give us a very reasonable quote and answered all of my questions about cellulose, spray foam, and attic ventilation. With the spray foam we had to leave while it cured, so I just gave him my keys which is a lot of trust in a stranger. These guys were super knowledgeable and professional, made the whole process easy, took a bunch of before and after photos, and even vacuumed before they left. We had the roofing contractor come out to take care of some vents and he agreed that they did a great job with the insulation and putting in the baffles and plugs so we can add extra intakes. Anyway, I've been putting this project off for four years and I'm glad it worked out so well thanks to Thermal Building Solutions! ✨

We had a new roof installed after 25 years and decided to upgrade our attic insulation. I researched multiple companies but was so impressed with the information regarding the different types of insulation, the timeliness, and the personal attention of the owner Niko, that we chose his company. He came over and surveyed our attic, described our options and quoted us a very reasonable price for the work to done. He promptly scheduled an appointment and had his staff come to our home in under two weeks. They were fast and efficient, and did a great job cleaning up the involved area. The work was done in March 2025. In June 2025 I came across an opportunity to apply for a Home Energy Rebate. This offer required an invoice with very specific details. I contacted Niko to ask if would send me a revised invoice with the necessary information. He promptly and graciously took the time from his busy schedule to help me out. Niko and his company are truly outstanding with excellent work, stellar service and affordable prices. I give my highest recommendation for Thermal Building Solutions!

Koala insulation did a fine job on my project that. I got estimates from 2 other companies, who bid 2x higher for, and didn't want to do what I wanted. They only wanted to spray foam, and not use batting. I needed to use batting between the floor joists, so I could have access for future duct work that I need. I appreciate Koala being honest, really pleasant to work with, and with very fair prices. For a first time home-owner, I appreciated Bob taking time to discuss options for the job, and treating me with respect. I didn’t get that from other companies. For the first section Bob, Nolan and Jay foam sprayed the edges and used batting between the joists. They had to enter the crawl space through a small opening where a window had been. For the other section, they had to fix what a previous company didin't do---that company sprayed the edges, but did not add batting between the floor joists. They moved the sofa, and crawled underneath, where they had very little wiggle room. They also did a great job cleaning up after themselves, and making sure I was happy with the carpeting and furniture put back in place. If you want honest, pleasant workers with fair prices, I highly recommend Koala. They came on time, and got the job done on time with smiles and good humor.

Koala did a great job from start to finish. They came out and gave us an estimate quickly. And from there they did the job just a week later. I think our attic being pretty small allowed them to squeeze us in. They did very thorough work and took good pictures. I would hire them again. One of the can housings for our recessed lights was loose and they even fixed that.

Greg, Bob, and Nolan did an amazing job and took care of my pole barn. They did it in a multi step process which i liked and gave me time to see the whole project progress from the estimate to the final spray. Pricing was great and Greg worked with me back and forth for the best option and for the best price. Once it came tome to spray Bob and Nolan came and moved everything out of the way, put plastic over everything and were not bothered by my big tool box or air compressor etc. then they filled all of the steel seams with a thinner foam and came back the next day to do the big spray, we let it air out over the weekend and they came back on monday to carefully and respectfully remove all of the plastic and scrape the surfaces where i plan to put up OSB for walls. If i ever move i will have another pole barn and Koala will insulate it. I tried uploading pictures but I'm not sure if it's working.

Fast, professional, and very helpful in assisting with the paperwork for us to get a rebate on our crawl space encapsulation. Sales person was very chill and not pushy which was appreciated.

Amanda and team went above and beyond in ensuring that they did the job they had said they would do, at the price at which they said they would do it. They performed robust quality control checks, and detected and fixed imperfections on their own. Our house is more comfortable because of the work they did (e.g., lower temperature difference between first and second floors). When we bought our house, the calculated maximum heat load was ~60,000btu/hr. After all the insulation work we got done (including some with other contractors), it is now

I recently had the opportunity to work with Wayne and his crew at Ecotelligent Homes, and I am thoroughly impressed with their service. They were exceptionally responsive, addressing all my inquiries quickly and effectively. The team was timely in completing the project, demonstrating a strong commitment to meeting deadlines without sacrificing quality. Their professionalism was evident in every aspect of their work, making the entire process smooth and enjoyable. I would definitely hire Wayne and his crew again for future projects and wholeheartedly recommend them to anyone in need of reliable home services!

had a great experience! they did the job for a great price, were able to offer better services for the price (compared to other companies in the area), they were very transparent, inspector/estimater was very knowledgeable, trustworthy and easy to talk to, they were able to work around my schedule, was able to provide me with referrals for other work that i needed around my house, workers who performed the job were fast, friendly, knowledgeable and cleaned up everything very well after completing (not something you come across very often). I would recommend this company to my family & friends!

We had our attic insulation topped off today. I had a great experience with Mike from Zebra Insulation. I highly recommend his service. Gave us a great price and the work was done quickly and professionally. Zebra Insulation is a family owned business.

Many thanks to Zebra. I'm very happy with the work they did insulating our rim joists. My project was a little less than their minimum order, so they provided some recommendations on additional services that would help fill that minimum. Scheduling was easy and they showed up when expected. It took them only about 1/2 a day which included spotless clean-up. And then they completed and submitted all the paperwork for my DTE rebate, for which I received a rebate check promptly.

USA Insulation was amazing to work with. Steve (sales rep) was very friendly and knowledgeable on our needs. We had two projects done. First crew came out to install installation in our attic. The second project we had Foam installation installed in our basement. This was a bigger project. The crew was very professional and took their time to tarp all of our personal belongings The clean up was spotless. Definitely recommend USA Insulation.

Andy was our sales representative, very knowledgeable, professional and prompt for appointment. He reviewed our needs and suggested foam insulation for walls and fiberglass insulation for attic. We signed the contract that day and he scheduled job to be completed the following week. The team called to confirm date and time and arrived at 8am. Zan, Darius and Collin did a fantastic job and explained every step prior to beginning job. They were very respectful of us and our home. They were done in 4 hours and did a great job of cleaning up after themselves. We look forward to lower energy bills and warmer winters in our drafty bedroom. Thank you very much.

Our experience was excellent! Steven Fitzpatrick was a very knowledgeable and up front salesman. He let us know exactly what to expect and the cost was very good! The insulation installers led by Cassandra were exceptional. Worked fast and cleaned up all the mess. I highly recommend this company!

I had a great experience working with Koala Insulation to get a quote from them for a client of ours who was looking to complete a home addition. The owner Greg communicated every step with ease and the amount of description that was put into the proposal was very impressive. You know what you're getting and how they intend to complete the installation. If you're in search of a company that you can trust that won't leave you wondering, I strongly suggest contacting Koala. You won't be disappointed!

UPDATE 3: Koala Insulation of Greater Ann Arbor and Brighton fixed the problem I shared in the review below, and I'm very happy with the work they did. I appreciate how communicative Greg and Bob were, and how they took care of me as a valued customer. I highly recommend Koala Insulation of Greater Ann Arbor and Brighton and am updating my rating to reflect the great service I received from Greg and Bob. --- This is an update from a review of Koala of Mid-Michigan. I made when I had my new insulation installed in summer 2024. I paid for R-38 cellulose for my attic. An independent attic inspector recently went into my attic and said this is worst, lumpiest insulation job he’s ever seen. He said I did not get R-38 like I paid for, because it’s not evenly 10 inches of insulation all across the attic.

I have personally worked with koala on multiple projects and can tell you they truly care about the outcome of the work that they do and the customer that’s receiving it.

The building inspector just said, "Oh, Spink, they're the best. They do great work." He's right. We've used them several times with great results. They're also polite, punctual, easy to reach, responsive...

Excellent service at reasonable prices. We had several quotes to insulate our new build home and they had the best price. They were timely and efficient. Will use them again for future construction projects with my remodeling business!

After a kitchen remodel on our ~1950s home, we found ice forming on the tops of some of our recessed lighting cans in the attic during winter, meaning we did not have good insulation and air flow in our attic. We had both Home Depot and Spink come out and quote us on adding insulation and fixing air flow problems (installing baffles, clearing insulation from soffit vents). Both quotes were almost dead-on pricewise (within $10), but Spink's quote included more insulation, getting us to minimum R50 in our attic, whereas HD was less. Additionally, Spink was able to schedule the job within a week, whereas HD was booking 2+ weeks out. Finally, Spink also offered to do and submit the paperwork for DTE rebates, which is a nice bonus. The installers arrived and got right to the job. Joe got into our attic, poked around for a few minutes, and immediately explained everything, in intricate detail, to my wife and I. What they were going to do, the air flow issues they noted, how much insulation they were going to add, etc... They put down drop cloths to protect our newly-refinished hardwood floors, and they were careful to get the worst of snow/salt off their boots when coming inside (it was actively snowing outside). Within about 2 hours, they had completed the job and cleaned up. Again, Joe went through all the details of what they had done, and made sure we were happy. I took a peek up in the attic, and we ultimately ended up with close to 18" of insulation, which is even above R50 (R50 is about 15.5"). We were very happy with Spink, and would definitely recommend them for any insulation job in the Ann Arbor area.

Couldn’t be happier with Weatherwise Insulation! The salesman, Dave, was knowledgeable, involved and went above and beyond to make this happen. The employees were punctual, hard working and did an amazing job.

I shopped around several companies to insulate my new 30'x64' pole barn. Ryan met with me, provided great advice and submitted a very fair proposal. The work was done in two stages: foam for the exterior walls and then, once I was prepared, cellulose for the ceiling and interior walls. Different teams did each phase. They were all friendly, helpful and very professional. I couldn't be happier with the great work they did for a fair price. I highly recommend them.

Not sure why anyone would give Weatherwise any rating other than 5 stars?!?! Ryan and his team were nothing but accommodating and professional Ryan went out of his way to accommodate my issues for scheduling. Phil the installer and his crew did a phenomenal job! Amazing clean up after install and the foam installation was better than anything I could have imagined. The crew sprayed in my existing garage that had of large amount of items remaining with no overspray or any noticeable issues Very thankful a friend recommended Weatherwise to do the insulation. I would recommend anyone with insulation needs to contact Ryan and his team for a solution.

My issue appeared to be an attic insulation issue, but after great listening April realized it was really an air quality issue. She plainly explained what would be best for us. She was clearly knowledgeable. And, while she definitely could have recommended work and made some money off of us, she didn't. She took a bit more of her time to explain what we needed to do and gave some product recommendations. I will always give someone like that 5 stars.

I scheduled April Rue, the owner of Ms. Green Construction to give us a quote on a couple of jobs. She looked at the areas and explained why we should not do them given the needs of the area. She was incredibly knowledgeable about the multiple needs of this complex space and gave us numerous, specific fixes that she would not benefit from. She blew me away and I wanted to leave a review because of that.

April was phenomenal. This company is so honest. They talked me out of the most expensive insulation and told me why less pricey solutions would actually be better for me.
