"The windows look great. Half of the windows were installed in one day"

"Absolutely thrilled with the window tinting service! The professional tinted 9 windows in my house flawlessly. The quality of work was exceptional, and the attention to detail was evident in every window. Not only does my house look fantastic, but the temperature inside is noticeably cooler. The entire process was smooth, from the initial consultation to the final inspection. Highly recommend this window tinter for anyone looking for top-notch service and results. Five stars!"

"Lewis and his team were responsive, timely and professional. Upon inspection of the windows, Lewis offered a wide range of films from which to choose and explained the benefits of each, so that I made the appropriate choice for my project. Seven windows were treated at my residence, including the removal of 30-year-old tinted film. I now have a lifetime warranty on the new Solar Control film. The job took just a bit under six hours and I was instructed on the care and maintenance of the film. All in all, a pleasant experience. Highly recommended."

"Excellent job on my windows...they now sparkle!!!"

"This company is great, I have you used them in the passed and they have always been great, with very knowledgeable techs, fast turn around time and beautiful finished work. I would highly recommend Window and Door Group for all your window and door needs."

"The windows and doors are beautiful and the installation was done expeditiously and the installers took great care to clean up as they worked."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"Guinn & Sons did an incredible job installing my impact windows. They were professional and efficient. I highly recommend them to everyone."
