Great Job ! By participating in Duke Energy program connecting to contractors, we connected with USA insulations. Justin came out for estimate. We chose USA Insulations from the 3 contractors that responded from Duke Energy, they gave us the best pricing & quickly scheduled the job. Their team was great, prompt, done in few hours, cleaned up and walked us thru what they did, double checked work making sure we were happy& satisfied at every step. David followed up with us to make sure all was good as well. All the crew & office personnel were great, very polite, knowledgeable & helpful. We are enjoying the improvements & would recommend using USA Insulation. Thank you USA Insulation !!.
This company was great to work with and they done everything they said they would do. We call and in a couple days Jason came out look around told us what we need and he even compared a few different opinions. The team of Todd ,Raheem and Greg were easy to work with and very well mannered. These guys don't waste anything they finished my house in 1 and 3/4 days. They put all vinyl back and cleaned up what little mess that was made. We r one happy customer and would recommend this company to do your inslation work.
We needed to insulate a 75 year old farmhouse in the mountains. USA Insulation worked with us to find the best options, including using injection foam insulation in the outside walls. They were professional, friendly and pleasant to work with. They explained not only what they were doing, but also why they were using that method & materials. They also traveled 2 hours each way to provide their services when other companies told us it was not possible to insulate outside walls that old without removing the inside walls then replacing them. We are extremely satisfied with this company, their crew members, and the finished project.

I gave these people a call about installing some gutters. They came out promptly to give me an estimate. The price was reasonable. The workers that came out were very friendly and professional. The work was very well done. I would recommend them to anyone.
Very good experience. Tim came over and gave me options that actually saved me money on my gutters. Could have brought a crew and charged me but didn't. Also gave me the name of another company that helped me with some siding repair. Completely satisfied.
After ice damage, they quickly got me a quote and they were there the next week installing the new gutters . They were quick and clean and the work looks great.

Rick McKinney and McKinney Insulation did an excellent job insulating my home. Rick is professional, courteous and knowledgeable. They have been in business 38+ years. Rick also got me Duke Energy’s $250 rebate for upgrading the insulation in my attic. My electric bill was cut by 60% after the insulation upgrade. If you are considering lowering your electric bill or insulating a new home I highly recommend Rick McKinney at McKinney Insulation.
They were very professional from sales to install. Highly recommend them and discovered they are a Duke Power certified partner and will complete the installation rebate with Duke Power for you if qualified.
McKinley Insulation gets 5 stars and more! Two gentlemen came today installed a vapor barrier and insulation in my crawl space. Their work ethic was incredible! I could not have asked for more efficiency and quality! Job well done!!!

Great. Friendly staff, fast to unload. Overnight parking. Just stay over towards the curb. I'd highly recommend backing in as it makes things easier to setup to the dock, especially if you get there at night
Great people. Best in triad... If you need real quality work. This is the place to go

We’ve worked with Renn Building Products for several years and they continue to be one of our most reliable insulation crews. Their work is consistently solid, they show up when they say they will, and they always get the job done right. Highly recommend their team!
We purchased a newly built home the latter part of 2017 and Renn Building Products was subcontracted by the developer to do the guttering. After being in the home for awhile we noticed huge crevices in one of the side yards and realized that the water gushing from the gutter on that side was causing the problem. I called Renn 5/14/17, spoke with a female person, explained my issue and was told that the sales person for this area would contact me and discuss changing the direction of the flow. After (4) days and not hearing from anyone, I called Renn again on 5/17/17, spoke with the same female person who apologized for the lack of follow up and said that my info would be given to the sales person again. Well, it's 5/20/17 and no word. Guess the sales person was in an episode of "Gone With The Wind."
Terrible customer service. Our builder choose Renn Building Products to install our closets. One side of our closet fell. Called for a quote and to schedule a repair. Two days later the sales person "texted me" saying my property was out of warranty and the repair would be $250. I asked for clarity on why ONE SHELF ( 4 SCREWS) would cost $250. Received another text message back saying, "I will call around and see who can come after hours". Never heard back. Never asked for a free job or after hours. Just asked why this SIMPLE job would cost $250. Clearly they do not want or need my business. We went elsewhere. The whole interaction was a waste of my unlimited text messaging.
