Our home needed the attic insulation replaced, so I reached out to Insulation Commandos. Martha and her team were incredibly professional, honest and considerate. They are people with high integrity !! I highly recommend using this company for all your attic insulation needs. Many homes are under insulated and you need to give them a call.
Had a great experience working with them doing attic insulation! They did a great job, from showing up for a quote all the way to getting the job done with great quality at an exceptionally great price! The best part is that they offer something nobody else does: blown rockwool. My suggestion to everyone: ask ChatGPT (or other AIs) for a comparison table along with pros and cons for rockwool vs. fiberglass vs. cellulose. Looking for quality great price longevity durability performance, insulation commandos is the way to go
The insulation commandos showed up on time, had well maintained equipment, put down protective barriers on woodwork, and installed 1 ft of insulation in the Attic. They also helped remove some boxes that needed to come down from the attic and when they were done they cleaned up everything including the garage. The crew all had uniforms and were extremely courteous. He was a great experience!

Highly Recommend Marko and Insulation First! Marko did a fantastic job installing insulation in my house. From start to finish, he was professional, knowledgeable, and detail-oriented. He explained everything clearly, showed up on time, and made sure the job was done right. The difference in comfort and energy efficiency was noticeable immediately after the work was completed. I really appreciate his honesty and the quality of his work. If you’re looking for someone reliable and skilled for insulation, I definitely recommend Marko and Insulation First!
Insulation First is amazing! They took out the old insulation, sealed up all the leaks, and sprayed new insulation! all without me even having to be there. They made the whole process super easy and stress-free, and they documented everything so I could see exactly what was done. When I came home, the job was finished perfectly. Couldn’t ask for better service they’re truly #1!
I recently had Insulation First install insulation in my home, and I couldn’t be happier! From start to finish, the team was professional, friendly, and efficient. The quality of the work is excellent, and I can already feel a big difference in my home’s comfort. The price was very fair, and the service went above and beyond my expectations. The crew arrived on time, worked quickly, cleaned up after themselves, and made the whole process stress-free.

Jimothy is a very nice, clearly honest, and knowledgable guy when it comes to insulation and ventilation. He came out to get a good look and take measurements of our existing insulation and didn’t charge. His team is easy to work with and they get a good job done very quickly! Highly recommend!!
Upgraded from R38 to R49 with blown fiberglasblown insulation. Extremely happy with the results. Most importantly, communication throughout the process was excellent. I’d definitely reach out to them again for any future attic insulation needs!
Was starting to build my shop. Getting all things in place. Was great to talk to text. Whatever was easiest way to communicate. Gave a great price. Got them scheduled did a fantastic job. Cleaned up when they were done. Covered all my plug electrical boxes the doors windows. Amazing to work with stood behind the price they gave me. Very pleased and would highly recommend them to anyone. Have already given referrals to other people. Fantastic work.

Julien has come out and spent a LOT of time in the attic taking measurements. He is nice to deal with, and I am awaiting the installation of spray foam insulation in the attic.
Karen with iFOAM has been extremely helpful and courteous from day 1. We had to push our project back several times from June to November and each time, everyone was understanding and professional. The crew was extremely efficient as well as professional. Thank you also to James Bishop for being flexible. I will recommend iFOAM to anyone looking for spray foam insulation for their project. Thank you from Bill and Elizabeth Fouts with K9 Kind Resort for helping us get our facility looking great and well insulated from the elements.
Joey, the salesman, was fantastic, and Santiago, the technician, was amazing. I made a last-minute decision to do spray foam insulation in my shop and office, but it had to be done early the next week. At 5:00 pm on a Friday, I called two companies to get estimates. I had to leave a voicemail for the first company, but the iFoam team answered the phone and Joey was at our place Monday for an estimate. He was transparent about everything, including pricing, and had an estimate for me the same day. Because I was pleased with the estimate, and the other company couldn’t get to my place for an estimate until Wednesday, I made the decision to go with iFoam. Miraculously, Joey pulled some strings and they got me on the schedule the next day! Santiago showed up in the early afternoon, alone, and went above and beyond to ensure everything was prepped and protected. He stayed until after 8:00 pm to get everything foamed and returned with his helper first thing Wednesday to shave everything down, so we could hang sheetrock the same day! I’m so grateful for iFoam’s sense of urgency and focus on quality, I recommended them to the general contractor doing all of the work on our house renovation.

From start to finish, the project went well. Jody came out to give a quote and was thorough and gave recommendations without being pushy. Once the quote was confirmed, it was scheduled within two days. The crew arrived and handled the job quickly and with no issues. They were kind and handled business. We opted for the additional solar fans with the project. The roofing crew arrived promptly at the provided time, they worked well alongside the insulation crew and were also wrapped up quickly. Great, smooth experience on a project we’ve needed done.
I used this company to add some blown in insulation in my attic. Their team that came out were friendly, focused, and did a great job getting me to R-38. I look forward to lower utility bills.
Kevin and his team were great to work with. We have a 75 year old house - One unexpected benefit is that they completely vacuum out the old insulation and go back to the studs - and then seal with foam and then blow in the new. Maybe it's in my head but it was 95 out yesterday and the house was noticeably cooler. Great job.

I had a great experience from start to finish. Estimator/Service Advisor Jeffrey Stuart accommodated my schedule by coming out when it was convenient for me. I had an afternoon open, so rather than pushing it out a week so it wouldn't be so hot while he was measuring(I wouldn't have blamed him, summer's really been hanging around this year), he came right over. I was impressed with his manner, professionalism, and expertise, so much so that I pulled the trigger and accepted the proposal shortly after he left. Next up was scheduler/coordinator Gie. She was pleasant, courteous, and responsive, and made me feel that she was going to be super accountable and diligent. She did what she said when she said without the typical misses or postponements/excuses so common these days. Project manager Tyler clearly laid the process out, and stopped by before and after. He made sure I was pleased and had no unanswered questions or concerns. I was lucky enough to get the install done by the team of Aldo and Armando. Prompt, competent, tidy and as quiet as circumstances/machinery allowed. They were just great and I was super comfortable to have them working at my home. Price was very reasonable too. AC is running less and garage is outside temp+ 3 or 4 degrees; it had been +20-25. Top notch job and I couldn't be more pleased!
Our experience with Superior Attic was fabulous. We had Jonathan out to check out the attic and provide us with different options for keeping the home very cool. We decided to go with the spray foam insulation between the rafters. We have just completed a full week with new insulation and so far have noticed a difference, cant wait to see our bill lower. We also had duct cleaning done which was needed. Seamless process!! Had another project done, came out great!! Love the process.
Superior Attic did a wonderful job from start to finish on our insulation replacement. I was impressed with the level of professionalism displayed by the entire team, including Steven, Tyler, Aldo, Jamie and office staff. Great communication and on time. The day of the job, the team worked hard all day, no loud music, no shouting or lounging around - just worked hard and finished the job ahead of schedule. They insulated areas that our builder had not, so this was well worth it! So happy with the work they did!
