See What Our Customers Think

“Jason took the time to answer all my questions and concerns. He never once steered me in any direction, rather he always asked what ‘I wanted.’ As for the installation, the crew was outstanding! They were very courteous, and installed 5 doors and 4 windows in just about 7 hours. They cleaned up well after the installation. My overall rating is excellent.”
H. Cardwell


“My sales person, Jason, was very professional, knowledgeable, pleasant, and answered all my questions to my satisfaction. The installers, also, were professional, courteous, knowledgeable and pleasant. The installation was not the job I had anticipated, instead they made everything easy for me, and I was extremely pleased with their workmanship.”
G. Absher


“Sales representative was an excellent communicator and explained things. The men who installed windows were excellent. They did not waste any time installing windows, I thought they were great.”

W. Jones


“I am writing to inform you how pleased my husband and I are with the window replacement work performed at our home on March 19th, 2012, and especially how professional and courteous the two installers (Arek & Robert) of those windows were while working in our home. Both of those young men exhibited knowledge, caring, and confidence which made us feel very comfortable having them in our home. Workers like these make people, such as us, faithful consumers of your product, and we will definitely recommend you to our friends and neighbors. I also want to take this opportunity to let you know that your sales representative, Craig, is exceptionally proficient and pleasant. He explained all the window options to us and represented your company in a very professional way. Needless to say, we are very happy with our new windows.”
