The process was very seamless for us and super quick. They came by and gave me an estimate on the spot, once I reviewed and paid, they scheduled me for just a few days later (the next week). They sent me texts to let me know when they were coming and were on time. They got to work while I was on a call which I appreciated so they didn’t wait on me. They had me check everything after they were done. They even taped up some duct work tape that was falling down. And cleaned it all up. And were faster than I thought they’d be too which is always a bonus. Nice group of guys too. Very happy with the work.
Great group to work with. Mark came out to the house and walked us through the entire process and all our options. We received our quote as promised and were provided several options from which to choose making it easy to stay within our budget. James and the install team arrived early. They were courteous, professional and extremely respectful of our home during the entire install process. After everything was done and cleaned up, James and I inspected the attics - over garage and over house - so I could see everything they did. I would highly recommend Mark and the Insulation Commandos Team.
We recently had Insulation Commandos remove our existing blown-in attic insulation, air sealed all air-gaps, and blew in new insulation with a higher R-rating. We even had them install a radiant barrier for extra goodness. It has been several weeks since install, and the difference has been night and day - especially upstairs, where our upstairs HVAC now runs less and the temperature stays much more comfortable. Mark and his team were extremely friendly, professional, and accommodating - even when it came to working with us on payment for their services. They also kept us updated on their progress and took the time to explain what they were working on, which we really appreciated. Overall, the experience was fast & smooth, the results are noticeable, and the team was great to work with. Highly recommend Insulation Commandos of North Atlanta!

Guys did a great job. Excellent communication and very professional. I would recommend.
Sometimes in life you have to accept the fact that things don't go as you plan but when people are nice and genuinely kind-hearted it leaves a wonderful impression on you. I spoke with a lady about a job at this business about a job and even though I didn't get the job her genuine heartfelt response made my day. Never be fooled there are still some Good People in this world!!

We identified Rite Way through a Google search and we are sure glad we found them! They topped off our cellulose insulation in our attic and from start to finish they did an awesome job! Our main contact, Nick, first came to our home to inspect our attic and he explained in detail what he saw and provided several recommendations and then he provided a competitive quote. After setting up an install date Nick was the main installer so we felt super comfortable that we were going to get exactly what was described in their quote. Nick was super attentive to detail at every step and after they completed the job I did a full inspection of the attic and it looked great and was fully covered in insulation (see pic) as promised including a very challenging hard to access area that the original builder never filled correctly. My heater is not running constantly now so we are super excited to save on our energy bills :). By far the best customer service from a contractor in the past two years and we have had over 10 contractors working on this old house.
What an amazing company! Lowest priced in the entire ATLANTA area! Other companies wanted 6k+ for 2300 sqft attic! The guys were amazing and my electric bill is back to normal! Thank you guys!
I had them add extra insulation in my attic.....noticed a drop in my power bill and the house feels warmer. Would recommend these guys.

Bird Family removed old attic insulation and replaced with new. Beau did the initial consultation and was very informative. Chris led the project and the entire team was great. They took great care and there was no damage to the floor, ceiling or walls. It was a great experience and would use them again.
The Bird Insulation team tackled my air sealing and insulation project with me earlier this year (February 2025) on my 1944 single floor home. We decreased my power and gas bills by 30+%. The scope of the project included removing all the old fiberglass insulation, air sealing around ALL ceiling openings, and installations cellulose to R-40. Removal of the old insulation was a couple hour process. They were diligent enough to get under the existing HVAC walkway. They then gave me a couple of days between the removal and follow up installation to tackle some HVAC items I had planned. Installation went as well as the removal. They efficiently air sealed the ceiling openings, treated the space with a disinfectant, and added the cellulose. The dust generation was limited as they mix the insulation with a small amount of water. They installed my attic stair tent and sealed that as well. We reduced our power bills by 30+% while also making the home more comfortable (reduced air draft). A win-win all around. Communication was great through the whole process. I couldn’t have asked for a better experience.
10/10! 5 stars! This summer (2025) has been ruthless so far and it's not even July! I called Bird Family Insulation on Monday, got a quote on Tuesday, and completely insulated my attic by Thursday. Not only did they insulate my entire attic but they also removed all of my old insulation as well. They were timely, professional, honest, and affordable! ALSO, they are family-owned which I love to see! Most of the people that you will deal with are family. No sneaky, sleazy contractor trying to squeeze the most money out of you. 10/10 would recommend!

The service from Authentic was exceptional. From the initial consultation to the final installation, the team was professional, knowledgeable, and respectful of the home. The process was clearly explained, all questions were addressed, and the work was incredibly efficient. The quality of the spray foam insulation in the attic is top-notch, and a significant improvement in the home's comfort and energy efficiency has already been noticed. This company is highly recommended for insulation work!
⭐️⭐️⭐️⭐️⭐️ “Authentic Insulation Smart Solutions exceeded my expectations in every way. Their team was professional, courteous, and very detail-oriented. They took the time to explain the best insulation options for my home and made sure the work was done right the first time. I noticed an immediate difference in comfort and energy efficiency, and my HVAC doesn’t have to work nearly as hard now. Honest pricing, quality work, and excellent customer service — I would highly recommend Authentic Insulation Smart Solutions to anyone looking for reliable insulation services!”
Had to leave a review!! What I really enjoyed was how well they explained the process and the benefits of having it done. Never felt like I was being handled, or that they were trying to "up sale " me to make more money. I really appreciated that, keep up the good work guys!!

From the initial visit where I was given the estimate by Charlie, to completion of the job by Hector and Eric, this company has exhibited nothing but the utmost professionalism. The crew was very conscientious of my home, putting blankets down and making sure they didn't leave any debris behind. Very satisfied, would definitely recommend.
We had insulation installed and the duct & vent system cleaned Great customer service Fair pricing Install was prompt and seamless Staff were courteous, professional, very thorough & explained the process step by step They cleaned up after each step - house was spotless Highly recommend!,
Aladdin Insulation truly exceeded my expectations. Their fair quote and professional service set the stage for a remarkable experience. Charles, the owner, was not only always responsive but also incredibly helpful throughout the process. Eric and his on-site crew were a delight—friendly, communicative, and always ready to assist. They did a wonderful job, addressing all my questions with expertise. I'm very pleased with their friendly and knowledgeable service, which went above and beyond. Without hesitation, I would gladly refer Aladdin Insulation to friends and family.

I wanted to share my experience with Alex at USA INSULATION of ATLANTA. I am having a huge issue with crazy high power bills. Alex came out to inspect my property and make recommendations. He was very professional and knowledgeable but most of all, he is a very HONEST MAN. As it turns out, insullation is not my issue, my HVAC system is the culprit. He could of given me an estimate and I could have paid, but that is not my issue and he was honest enough to tell me. I would use this company again for any needs I have. Thank you Alex for your integrity!
Great job!!! Re- insulating the attic and outside walls has made a difference. Tony was an exceptional sales person. Knew his facts and showed us why we needed to have the attic redone. The install team was also great. Quick, efficient, and cleaned up after themselves. Definitely would recommend.
USA Insulation was great from start to finish. Alex came out and listened to our issues and assessed what we needed instead of trying to sell like other insulation companies. Then Daniel & Felix did a incredible job with the install and wrapped it up by thoroughly explaining the work that was done (with pictures). These two went above and beyond and were great to work with. This was all made possible with Beth helping in the office. This group worked as a team to make our house more efficient and comfortable. Thank you again to the USA Insulation team.

Before settling on Green Earth Spray Foam to insulate our new home I met with and discussed my project with four of their competitors. Our project included open cell spray foam in the attic and all above grade exterior walls, closed cell spray foam on on below grade exterior walls and rock wool sound proofing between floors and living areas. Green Earth's pricing was very competitive and I felt very confident they were experts in installation. Matt Youmans at Green Earth was a joy to work with. Professional in every way. He enthusiastically approached our project to make sure the insulation solutions were a perfect match for our project and budget. His team delivered everything they promised on a timely basis. And he expressed true gratitude for having the opportunity to insulate our new home. My builder has 40 years of building experience and he was also very impressed by the quality of their work. I'm beyond impressed and thrilled to have chosen Green Earth Spray Foam and recommend them without reservation. If you need insulation for your home or business, reach out to Matt. You'll be glad you did.
I am absolutely ecstatic with the Green Earth Spray Foam Company. From the initial meeting and the quick turn around of their proposal. To the ease of the scheduling date. They showed up right on time and immediately went to work. The work was excellent which includes their prep’ and the clean up. The crew was friendly and courteous. With temperatures already heating up outside the benefits of the Green Earth Spray Foam Insulation can already be felt with cool/comfortable temperatures inside. I highly recommend!!!!
My experience with Green Earth Spray Foam was great, from the initial consultation to completion of the job. Matt initially inspected the attic area & offered recommendations that would help with differences in seasonal temperatures upstairs as well as overall energy efficiency. I received their proposal quickly & it was competitively priced. The team that came to do the work was efficient & professional. They completed the job in several hours & cleaned up before they left. I’m glad I chose Green Earth to do the work.

Wonderful company I had them come out today and insulate my addict they did a wonderful job very clean even. The prices are fair and they give you good communication throughout the whole process.
Great service, friendly faces, and an overall great experience! Had my attic insulation done, and I started to notice a difference in my house's temperature regulation very quickly. Not to mention the competitive pricing. Omar and Alonzo came out and did a great job with exceptional customer service. Would definitely recommend to anybody looking.
Rite Way Instulation is amazing. They did quick, high quality work. The guys were all very nice and professional. Our attic looks amazing and we couldn't be more pleased. This was by far a great experience. They keep us up to date on each thing they did in the process. They sent us pictures frequently and asked us often if we had any questions. We want to thank them for an awesome price and responsive time. We will definitely be recommending them to our friends and family.
