Insulation Contractor reviews in Knoxville, Tennessee

Had my garage attic insulation blown in. George and Jack did an outstanding job. Very professional and explained everything and took the time to answer all my questions. The insulation made a huge difference in the garage. Will defiantly be using RetroFoam of East Tennessee for future jobs. Highly recommend!!

I would very highly recommend Retrofoam. After speaking with the owner we hired them to insulate our garage and part of our new renovation. This is an excellent option to ripping out the drywall. They showed up on time and worked until the job was complete. They prepped the rooms well and when they were done, cleaned up completely. It been over a month since the work was done and we are are amazed at how warm our garage and home are now. We love it and are so glad we worked with Retrofoam!

We had foam put in the walls last week, and we can tell a big difference in temperature. Robert, Jack, Nathan, and George did a great job and cleaned their workspace really well. I will reach out to this company again in the future.

RetroFoam did a fantastic job sound proofing the master bedroom of one of my custom homes. Robert, George, Jack, and Nathan was very professional, timely, and even sent me pictures of the finished results. Will definitely use again!

Cannot express the professionalism and friendliness from the boss to the installers this was a great group to work with. Did a great job and cleaned up after themselves. Would definitely recommend with job well done.

I've known of GES and Eddie Sanford's excellent reputation from friend's positive experiences. Although I only needed a small amount of foam insulation, I contacted Eddie for the job. It's been a huge improvement since adding the foam. It's been a few weeks with mild temperatures so hard to tell if my heat and air bill is less, BUT I know there will be! How do I know this? Because I can't hear the trash truck anymore at 6am! I highly recommend the retrofoam system with Eddie and his crew installing it!

I couldn't have used a better company for our insulation job. Eddie and the crew from RetroFoam of East Tennessee were very professional and friendly. The guys were knowledgeable and informative of what they were doing and any safety precautions we needed to know. They made sure to put down protective plastic before they started and cleaned up after they were finished. I would higly recommend Eddie and the crew from RetroFoam of East Tennessee.

Eddie was easy to talk with and forthcoming about the pluses/minuses and challenges of doing foam insulation through old mortar. The work was promptly completed, and they quickly responded to and addressed minor issues that came up, which were mostly pointed out ahead of time as possibilities of the process. The finished patch work was better expected, house is quieter and the HVAC seems to be running less, so far. I look forward to reporting back on the reduction in our KUB bill.

George, Nate and Robert installed foam insulation in my garage. They came as promised in the morning. They even helped me to clear the walls from obstruction items so they could get to work. These 3 guys worked intensively from beginning to end. We couldn’t have had any better team than these hard working men. We certainly would hire them again and we recommend them for any one who is going to insulate a garage or the walls on a garage. THANK YOU !

I was one of the first 7 customers of East TN Retrofoam ,probably 6 or 7 years ago,and I had them come out and give me an estimate to inject foam in my basement brick walls. I liked their quote so I hired them. They did an excellent job and you cant even see where they drilled in the mortar to inject the foam. My basement is a lot warmer and quieter now. I definitely will use them again ! Thanks Eddie!

Eddie and Robert were easy to work with. They weren’t in a hurry to make a sale but they wanted to make sure that their product would fix our issue. They came in and applied the spray insulation. We can tell a great difference in the temperature of our room.

This was a small job that others would not even look at. It was converting a carport into a two car garage with a single door. It has really made a difference in keeping our cars and house a lot cleaner. House is cooler and less street noise.
I thought this was going to be a small and simple job but when Kevin, John and Kent got started I was glad I did not try this myself because it would have been a mess. They did many things that made a huge difference in the out come like putting styrofoam strips glued down under the framing of walls. Every 2 X 4 was checked and made sure it was level and plumb. They worked fast and efficiently. The only thing that slowed them down was waiting on material. They put up with me watching and getting in the way and were really great to work with. They were very professional. I would highly recommend them for any project. I would definitely use them again.

The Team was on time and very Professional. They answered all my questions and showed me there process. If they encountered anything they told me right away and explained what they were going to do. the clean up was great as you could not tell they were here. Great group of guys very friendly and courteous. I highly recommend Retrofoam.

I've waited over a year before reviewing to get a good idea of how Retrofoam was working for my home. I had only the exterior walls done in my older home that has plaster walls. I haven't seen any real movement in my electric bill or felt a huge difference in how cool/toasty my rooms feel throughout the seasons.
I've owned the house for 9 years. I was concerned about wall cracks but was assured my plaster walls shouldn't be an issue. Cracks have formed in most all my exterior walls since Retrofoam was installed.
I used reviews as part of my research before I ordered the service. I was surprised on installation day to find out there was a $60 incentive for leaving reviews (which i didn't accept because i didn't know how I felt about the service yet). I became skeptical since customer feedback was a big part of why I decided to move forward. However, I had made a non-refundable deposit, workers were in the yard and minutes from getting started. I decided to cross my fingers and hope it worked.
Everyone was very nice, the crew worked diligently and left the house/yard in great shape. Looking back though, I haven't seen any real benefit and wish I'd never done it.

I had the exterior walls foamed first. The salesman was very patient, understanding, and helpful answering my many questions. Due to the distance, most of our communication was via phone, email, and text; all of which were prompt. The installation was efficient and methodical. They took their time to do it right. I got many explanations of how and why they were doing things. It took a little longer than expected due to the complexity of the project but I noticed a difference as soon as the walls were done. Quieter. The furnace didn't kick on as long or as often. I'm happy and it's only been 3 days! Thanks guys!
Several months later I had them redo my crawlspace. The removed the drooping insulation and foamed the floor joists then removed the old plastic and put in 8 mil plastic. The vents were replaced with a newer model that would open and close automatically. The night after they foamed the floor joists the heat didn't kick on for hours! Yes, it was a mild evening, in the 40/50 range but still. The next day the temps were still mild and again the heat didn't kick on for hours. I could sit without feeling the cold creep through the floor. The closets even felt not as cold. They hauled away the debris and cleaned up. They answered questions and were polite. It's been a couple of weeks now and still the heat runs less often then it did before I had the work done. I am very grateful for the excellent work they did.

This Company is awesome. Eddie is very professional and knowledgeable about everything pertaining to a remodel. I had Retro Foam come spray a whole ceiling to help with noise control and they were great. They are quick and efficient and you wouldn't even know they had been there when they left. I highly recommend Retro Foam.

I enjoyed working with Eddie during the sales process as he was extremely knowledgeable about building envelopes and how to properly insulate a home. Once the job started, Robert, Nathan, and Jacob showed up on time, worked hard, cleaned at the end of the day, and were a pleasure to work with. I would highly recommend Retrofoam if you are looking to insulate your home or business.

Insulated my Hardin Valley Storage office with retro foam and added insulation at the ceiling. Great experience with the crew and the installation. They covered everything and left the place clean. Eddy is involved in every job and was always available to talk to me. They are very professional and honest from my experience. I would highly recommend them for any insulation jobs you might have.

RetroFoam of East Tennessee just completed encapsulating my crawl space. The experience was pleasant from the first phone call to the office to the final cleanup when all work was done. The company delivered everything they promised on time and for exactly what they quoted for the cost. The friendly character of the office staff and the installers was so welcome. They responded promptly to every call or question and the work clearly showed their knowledge and desire to do the job right. I can recommend this company without hesitation.

Wow! I am seeing immediate results today and am utterly amazed at how cool my house is.
For the past 2 summers I have been battling HVAC issues wondering if my unit wasn't big enough or if my house couldn't hold the cold air and now I have my answer. RetroFoam WORKS!

Over the past 2 summers I've been battling whether my AC unit couldn't produce enough cold air or if my house couldn't hold the cold air. Last summer I went into the attic and blew in additional insulation on top of what I already had and saw little change. My outer walls had only a vapor barrier so I decided to pull the trigger on RetroFoam and I'm already seeing immediate results. I didn't realize but you can lose up to 35% of the energy in your house out of your walls. Today the outside temperature is only 71 but I have no shade on my house so it's always been warm. The day after installation I am physically shivering because my house is actually holding cold air! I couldn't be happier!

I can't recommend RetroFoam and their crew enough. They were very thorough about how the process would work and even customized their work plan to ensure that I had minimal patching afterwards. (I decided to go through the back of my cabinets in my kitchen opposed to my outer wall since it was on a porch) The process started with Eddie who did not pressure me at all. He simply came out to my house, had a look around, asked a few questions and gave me his assessment. In fact, it was so low pressure that I followed up with him a year later to decide to move forward. The crew that came out (Nate, George, Austin, Travis and Robert) was a pleasure to work with, very well mannered and ensured that the job was done correctly. Asking my opinion on multiple items before continuing just to ensure it was done how I wanted it done. I can tell this is 100% going to pay for itself over time.

If you're wondering whether or not it will make a difference, trust me, it will!

It was a struggle to cool our upstairs bonus room area due to our attic, bonus room, and the adjacent storage room having inadequate and in some places no insulation. When calling RetroFoam of East Tennessee for an estimate, Eddie talked with me for some time about our home before coming for an in home visit a couple of days later. He told us his recommendations (both RetroFoam and open cell spray foam) and answered our questions. The installation crew (George, Matt, and Travis) started their work less than two weeks later and they were obviously well prepared before their arrival from the pictures that Eddie had shared with them beforehand. It took them three days to complete the work as Eddie had predicted due to the many tight spaces to be navigated. They went to great lengths to protect our home and they cleaned up everything very well afterwards. I would highly recommend them to others needing insulation work.
