"Excellent job to spray insulate the existing attic. We have noticed a difference already."

"Eric responded immediately and set up a consultation. He was prompt, very polite, thorough and knowledgeable. He explained everything in detail and was very professional throughout the entire process. His pricing was also quite fair. The only reason I did not go with him was that I needed other work done outside of his area of expertise. I was able to bundle that work with another insulation contractor which better suited my budget at this time. I would absolutely recommend Eric and will definitely contact him, should I need any additional work in the future."

"Everyone I worked with at USA Insulation was courteous and professional. Cliff walked through my home and gave me a thorough estimate, going over all the work that would be done to insulate my home. Tyler and his crew arrived just over a week later. They were quick and efficient and walked me through my house to show me the work was done. I would absolutely recommend USA Insulation to anyone looking for a refresh."

"Great work, very personable, professional, courteous, and reasonably priced. Received blow in insulation for garage and entire attic in house… they hammered it out, did a quality job, and work very hard."

"Excellent repair work done on my deck on time."

"Friendly and professional company. Explained alot about what they were doing, cause I really didn't know anything about insulation and ventilation."

"It was the coldest day of the year so far and they still showed up and did the job which was all outside."

"The salesman that came to the house and gave the quote was professional and did not apply any pressure to buy. He listened to what I was looking to have completed and was able to give me a very competitive quote. I did acquire two more quotes but Seal Tech provided me not only the better quote but also the most comfortable. The installers showed up on time, took precaution to protect our landscaping and installed the foam insulation. We noticed that the application in the walls have left our home much more comfortable and over the past three months our utility usage has gone down at least 10% each month.

"They did a great job. On time both for the estimateand the installation of my blown in insulation. They cleaned up and were very nice. Highly recommend."
