Get matched with top window pros in Princeton, FL

"We purchased impact windows and doors to replace our old windows and 2 french doors, from Locktight and we couldn't be happier with the entire process and products. The windows and doors are everything we hoped they would be. Communication with Locktight has been topnotch throughout; and, the removal of the old windows and installation of the new windows was quick, incredibly professional and impeccably neat. The windows themselves are beautiful, high quality and nearly soundproof. They have improved the appearance of the exterior of our house significantly. We highly recommend Locktight to anyone considering replacing/upgrading their windows and/or doors."

"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."

"Steve is very hard working and he did a great job with my windows. I have used him twice already."

"Very professional, very polite, very reliable. They did everything they could to solve the issue with the window quickly and economically. I would hire again if needed."

"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 replaced all of our windows and doors with impact at my house. I am pretty picky so they took the time to explain the options and products to ensure I was happy. Very communicative from start to finish and we love how everything turned out. They kept everything clean during installation too. I’m a realtor in Miami and I refer all my clients to them, and everyone has been very happy! I highly recommend them."

"We used Assured Storm Protection for our Front door and our hurricane ECO impact windows. I highly recommend this company. They are so organized and do a great job. I would use them again in a heartbeat. Heidi Kramer (Weston)"

"I am really happy with their service. They fixed all my windows and left them like new again. They were honest, professional, and punctual."
