The pictures uploaded are from my actual home. EVERYTHING was COVERED! It was so awful that I had to sleep in a hotel for a night until I could get a cleaning company to come deep clean my home. They did NOTHING to ensure that insulation would not be flying out of my attic and covering my entire household. They were extremely careless and unprofessional. I wouldn't even recommend this company to my worst enemy their so awful. This ended up costing my landlord HUNDREDS of dollars to get my house cleaned and put me in a hotel for a night so I wasn't breathing in insulation all night. Never in my life have I seen a worse insulation job than these people. I don't even know how their in business!!!! NEVER USE THEM!!!! NO STARS!!!!!!

As of February 20, 2026, Tennessee Valley Spray Foam LLC does not have a valid business license in…read morethe City of Huntsville, according to city records. According to Nationwide insurance (their carrier), he does not have proper coverage for this line of work: exclusions for environmental issues like off-gassing or chemicals, and no coverage for improper work or installation. I have text message documentation, emails, and all phone calls recorded (except rare in-person conversations). Tennessee Valley Spray Foam LLC sprayed my bus conversion on December 17, 2025. After installation, there was strong chemical off-gassing that hospitalized me. They sprayed summertime foam in 30° winter weather--should never be applied under 50°. Ryan stated it would be fine as long as the bus temperature reached 70-80° (which we heated to). He didn't mention--and seems unaware--that it must stay at that temperature for 24 hours after spraying to fully cure. He told me to open the door and let the fumes air out. This dropped the temperature immediately to the outside 30° temperature, and it dropped into the teens that night. The foam separated off the back of the bus. Spraying with drums outside in 30° weather caused a viscosity issue, making the spray foam mix improperly. This caused off-gassing of isocyanates. He also had his off-ratio protection switch turned off (I have pictures of that). He claims they weren't spraying at the time--the machine was only on--and that he turned it on later. They had to return a second day because coverage thickness was inconsistent and less than half the contracted amount, with 2 inches of variance when he guaranteed a half-inch total variance. Nothing about this job was done right. Ryan (the owner) has done nothing but make excuses and lie about the process. I contacted the manufacturer and trainers for installers of this product; based on my photos, videos, and temperature report evidence, they confirmed the job was done incorrectly. Everyone in the industry concurs it was improper and should never have been attempted this way--including the company bidding to reinstall once removed. It's going to cost me $7,700 for dry ice blasting to remove the residual. No other company will apply spray foam or offer a guarantee/warranty with his residual still there. The leftover residual is still off-gassing, causing a health hazard. Ryan said he would remove as much as possible but leave the wheel wells to avoid damaging the coating. I told him to get as much out as he could. They removed everything physically reachable, but it's still off-gassing and the rest must come out. I requested his insurance info in case issues persisted; he sent it. I filed a claim--Nationwide confirmed no coverage for improper installation, chemicals, off-gassing, or environmental issues. So he's not covered for the type of business he's conducting. I contacted the City of Huntsville (where he's operating and working); they stated his license is expired and he's not licensed. They require insurance he wouldn't meet if licensed. I told him he lacked proper insurance coverage. He claimed this job cost him $10,000 (impossible--the job was only $3,200; if he paid guys to install for that and profited, removal by his team over 3 days couldn't cost much more). He's always said from the beginning he'd make things 100% correct if wrong--but failed despite his inadequate attempt. He argued with the manufacturer spec sheet on proper installation (tack time 5-7 seconds after application; he said much longer). The foam was sticky for days with extremely strong chemical smell; the smell persists months later with residual foam. It is absolutely incorrect, yet he argues against manufacturer specs. This is 100% his fault and was completely avoidable according to industry professionals. He also should have corrected the problem 100%. Now he's told me to contact an attorney if I want--he's not going to do anything. I will be taking him to court.

Synergy has supported us throughout any of our system maintenance. They have come out to our house to help evaluate system performance. The president of the company even came out and went throughout my entire house to ensure that things were operating properly. He went through the attic and crawlspace. He made some recommendations, and he helped me better understand how things work. I was very impressed that he took such a vested interest in making sure I was comfortable with everything. I am very pleased with the spray foam, and I am even more pleased with the continued support from the company. I highly recommend Synergy of Decatur, AL.
