The best part of our job is our customers! See what they say about us:

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.

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.

Eddie Sanford struck me as someone I could trust to do a good job. I liked his story on the website and met him before I decided which contractor to go with. I really enjoyed talking to him in his office where he shared a test he just gave his employees after a training session to improve their knowledge and performance. I chose his team to help me put my flooded out crawlspace back together. Robert, Nathan, George and Jack did a great job. All of them were polite and professional. They kept me informed and politely endured my looking over their shoulders. Robert did a great job leading the crew. Nathan was a real gentleman with excellent HVAC knowledge and George suited up on a hot day to spray foam the crawlspace walls. He took his time and did it right. Overall I was pleased with the job and had a chance to interact with Eddie on questions and thoughts I had about the job. He was very accommodating. I would recommend Retro Foam. It was a rare good experience with a contractor who did what he said he would earlier than he said he would. Thank you all.

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.

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!!

The crew was great. I was only getting a small area done but Eddie worked with me and made it happen. Crew showed up early and went straight to work. Get service from Retrofoam.

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!

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.

Eddie with RetroFoam did an amazing job! We needed foam insulation for our rentals. RetroFoam helped us get this taken care of within the week. This is an excellent company. Falin Enterprises recommends them for any foam insulation you need!

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!

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 !

From the first phone call to job completion, Retrofoam of East Tennessee is a company I recommend. From communication thru completion, retrofoam met all expectations. The crew on my project, Mr. Jacob and Mr. Robert were professional, knowledgeable and expedient. They helped keep my project on schedule. Many thanks.
