"He asked that I call him in a month and give him an update on how my soundproofing plan was working. I've had my outside noise problem for a very long time, and after talking to Andrew, I now have a very good plan! It was a relief learning what things I could do to solve my noise problem. My highest compliments to Andrew Horvath for his patience and guidance. Thank you. Bruce Scarborough"

"They recommended that I did not need roof insulation. Very honest and professional opinion and advised if they performed the insulation (since he determined my insulation was very good), I would not realize any benefit. I really appreciated that honest evaluation. Would recommend them to anyone needing insulation; they are not a fly by night firm and in explaining what they do and how they do it, separate themselves from the rest of the pack."

Customers say: Quick response
"Very pleased with the customer service and the quality of work done by AHC Spray Solutions. The owner, Clint, was on time for his initial appointment and was efficient in evaluating the job and providing an immediate estimate to complete the work. The workers showed up to do the job on time and did the prep and post-job cleanup very well. I am pleased with the work and recommend AHC Spray Solutions to anyone needing spray foam insulation work. If I need another spray foam insulation job, I will call AHC."

"They did an excellent job. The before and after pictures really showed me what they did. They replaced the ducts that were damaged for less than what my a/c company was going to charge and replaced my insulation and did a lot more work as well. I am very pleased with them."
