"Locktight windows was a wonderful company to work with! It was an easy process from start to finish! We are very pleased with our windows. I would highly recommend this company if you are looking to replace your windows with hurricane impact!"

"Excellent service. Very efficient, clean, and respectful. My wife and both work from home and we hardly knew they were here. Window tint looks great."

"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."

"Team from Power completed the work on time and cleaned up well after work was completed. Windows were measured correctly so replacement windows fit perfectly and were quality Pella windows versus no-name windows offered by other vendors."

"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."
