Spray Foam Insulation in Knoxville, TN

Koala Insulation gave me a great price and great service for adding insulation to my attic. I got 4 other quotes and theirs was the best. I worked with Bob on the estimate and scheduling. He was very professional. The crew (Dylan and Woody) provided friendly and excellent service. They called before arriving, were on time and got right to work. They were done in just over an hour. Afterwards, they showed me numerous pics of my attic with the R-60 level of insulation. I am very satisfied and look forward to saving on my energy bills.

Great response and communication every step of the way from estimate to the scope of work. Even on call backs for new request items the work was completed at god speed with quality and attention to detail. I also wasn’t paid for this review like most companies do now.

Koala provided blown insulation for our entire attic and did an amazing job! They were really efficient and had the job done an hour sooner than they quoted and were extremely thorough and cleaned up everything afterwards. Great people to deal with and locally owned which is exactly what I was looking for.

Yen insulation service and fast thanks to foam blocker

Found him here on Google. Very friendly, professional, fast, and left no mess. In and out in two hours, bringing our 1500 square foot house up to code. He also helped us work with TVA to get a rebate. Best prices I could find in the area. They even worked quietly enough that none of our kids woke up from their nap. Could not recommend him more.

Contacted volunteer insulation to estimate doing a new construction house for insulation. Desmond came out on 1 day for estimate told all materials needed. Told me he would take care of picking all supplies up and ready to install on a certain day. Before sun was up he was at the house. Seems like before lunch he was done with all walls and allot of walls he started early and stayed late and my home was done before he left. He was more excited to get my house done before I was. I would highly suggest Volunteer insulation to anyone. Very knowledgeable on estimating and the actual install. Cleaned everything up. Very pleased. And his pricing is on point. I had 3 estimate and I took the middle one. My guys have told to get the busy one if you can. So I did. Thank you Desmond if you have any clients that want to see mine or talk to me. Please contact me be more than welcome to.

Desmond did an excellent job on insulating my sunroom and providing a moisture barrier. Best prices and best work by far. He was very efficient, thorough and cleaned up behind himself. I would highly recommend and definitely use Desmond again for any work I needed done.

TSF did an excellent job on our basement/garage overhead! Patrick, Lawrence and John were extremely professional and friendly to work with. They were on time and finished the job quickly, at a good price, and it looks great! They cleaned up afterwards and the garage is actually cleaner than before they started. I highly recommend TSF!!!

I could not be more pleased with the crawl space encapsulation and great service I received from Crawl Space Ninja. Adam and his team are professional, dependable, and top-notch Superstars in my book. Michael Church left a favorable and lasting impression when he installed a radiant barrier and fixed some attic issues for me about 15 years ago, which made contacting Crawl Space Ninja an easy decision for me when I suspected that I had problems in my crawlspace. As a realtor who encounters musty odors, moisture, and mold in crawl spaces frequently, I was terribly upset to realize that I had issues in my own home. Having worked with Michael previously, I was 100% confident that his company could resolve my problems and I was not disappointed. Adam and his team did a fantastic job. My crawlspace is now clean and dry and the peace of mind I now have is priceless.

This review involves a totality of my experience with Crawlspace Ninja. Last year (approx 1 year ago) we contacted Crawl Space Ninja for an estimate, as when we moved in, we discovered mold in the crawl space. They came out for the estimate and provided a quote. The downside is they had a miss in the quote since our house's foundation has a center split, which required two pumps, which added the cost of one more pump than the original quote. Kinda a bummer, but misses like this do happen. They provide the ability to finance through monthly payments, and we put enough down to have a 0% interest loan for the process. They got it installed within 3 days if I recall correctly. I can now actually go into my crawl space for turning on and off my home's water quite comfortably (better than crawling in dirt)! I forgot the guy's name that oversaw the install and installed a new door for the crawl space about a year ago, but he did a phenomenal job. Next up, shout out to *Milly* for always being super helpful and responsive for calling me back and scheduling, and for keeping us updated through the process. Finally, another shout-out to *Kyle* who came this last week for an annual inspection. I noticed the dehumidifier had an error code and called them out to check it out and just inspect the space. Kyle identified a defect in the dehu, got me on their schedule for a replacement, and had them out the next day to replace the dehumidifier. It was within warranty and was replaced without any hassle. So far my experience with Crawl Space Ninja has been excellent. They are a bit more expensive than the competitors that we saw when shopping around, but I have no regrets choosing them and would make the same decision again if I could go back.

I had a fantastic experience with Crawl Space Ninja, thanks to Caden and his customer service support partner Melissa. They recently assisted me with an estimate for mold remediation in the crawl space of my home, and I was truly impressed with their professionalism and attention to detail. Caden’s industry knowledge was evident from the start — he carefully assessed my situation, explained the findings in a way that was easy to understand, and provided recommendations that were tailored specifically to my home’s needs. Melissa was equally outstanding, offering excellent customer service support and making sure I had all the information I needed throughout the process. What stood out most was the genuine care they both showed for my specific situation, combined with a cost-effective approach that made me feel confident I was getting the best value. Crawl Space Ninja is clearly committed to quality and customer satisfaction, and Caden and Melissa exemplify that commitment. I highly recommend Crawl Space Ninja to anyone in Knoxville needing mold remediation, moisture control, or crawl space encapsulation services. Ask for Caden and Melissa — they are a great team!

Home Comfort Solutions did a great job! They were professional, friendly, and easy to work with from start to finish. The quality of their work really shows, and I appreciate how smooth the whole process was. I’d definitely recommend them to anyone looking for reliable, top-notch service!

I can not think of ONE thing that would make me happier with the HVAC system maintenance check and a new HVAC system install the Home Comfort Solutions team provided for my home. Our old HVAC air handler and condenser unit was deemed unfixable through our home warranty company. With that being said, I was a little leery of who would be called to check our system and perform the service and new install; you never know what you are going to get. The Home Comfort Team was punctual, happy, polite, knowledgeable, patient with explaining, were able to add additional equipment we requested, and responded to texts quickly! I highly recommend them. A huge THANK YOU goes out to Madison B., Riely R., Dylan and Steve.

We had such a positive experience with Home Comfort Solutions. We found our furnace was not safe to use right before a cold snap, and Riley helped us get heat restored. Riley was incredible to work with, and they all made me feel like they saw me as a person and not just a job.

Best experience ever! The technicians Carrie and Ian were both courteous and professional. Carrie communicated with me the entire installation and allowed me to periodically inspect progress. They did not rush and their work was quality start to finish. Jeff, my sales rep, was responsive and competitive. Very pleased with the results and would have them back anytime.

We did not comparison shop so I can't say how our price compared to other companies. My husband had worked with USA insulation before and wanted to use them for our insulation project We think it was worth it. We noticed differences right away. Our house was much quieter. And everyone that we worked with was great. Big shout out to work crew because they were wonderful! The project manager kept us informed every step of the way. They were respectful, efficient and cleaned up everything. They left the property looking great.

I highly recommend USA Insulation. Jeff was the best salesman! No pressure and informative. Carrie and her team did an awesome job installing our insulation in the attic. We didn't hardly know they were here. Very considerate of our home and space. Was a good experience all around.

From the very beginning, the team at RetroFoam of East Tennessee demonstrated top-tier professionalism and customer care. Eddie, the actual owner, went above and beyond—personally calling me to answer all of my questions, educate me on the process, and make sure I felt fully informed before signing the contract. His level of attention and care made it clear that my business truly mattered and that I would be well taken care of throughout the entire experience. The installation team was exceptional—courteous, respectful of our home, and diligent about cleaning up thoroughly at the end of each day. Their professionalism and attention to detail did not go unnoticed. Eddie, and Kevin our salesman, continued to deliver outstanding support by ensuring we had all the necessary documentation to apply for the TVA rebate and the federal tax credit. His follow-through was seamless and deeply appreciated. Retrofit foam insulation is a significant investment and not something to enter into lightly. Eddie, and Kevin, both helped us feel confident that we were making the right choice for our home and our energy future. We are already noticing the benefits, and we are looking forward to seeing the savings reflected in our utility bills. I cannot speak highly enough of Eddie and his entire team. They are honest, fair, and remarkably professional. If you're considering a project of this nature, I highly recommend giving them a call—you will not be disappointed

Eddie treated me very well and price was on the lower side of all the quotes I shopped. He came out and looked at the job gave me a quote and the guys were not to far behind starting the work. 50x60 steel building 2” Closed Cell Foam they knocked it out in 2 days. Finished product is amazing.

Recently, RetroFoam came out to insulate our garage. Our home was built in 2015, but the builder hadn't insulated above or in the walls of the garage. We received estimates from a few companies, but we were especially impressed with Eddie, the representative from RetroFoam - his attitude and professionalism stood out right away. On installation day, Nate, Gunner, and Robert arrived and did a fantastic job. They prepped the area thoroughly, completed the work efficiently, and left everything spotless. Their professionalism and work ethic were excellent from start to finish. The entire experience was smooth, and we couldn't be happier with the results. Highly recommend RetroFoam and this TEAM!

Awesome Service!! Joel was very helpful and did exactly what he told me!! Will definitely us him again!

Joel and his team are top notch.ive used them 2x and each time they've performed their job flawlessly. They've also not asked for any money upfront.

Joel and his crew did a great job and for a great price. Would definitely recommend and use for other jobs.
