“Chris was an absolute gem to work with and the window suggestions were perfect. The home was built in 1962 and had all of the old steel frame windows which were losing energy rapidly. We noticed an immediate change in the environment inside the house and the outside looks fantastic. Great installers.”

“Window replacement was for our elderly mother and the professionalism of the entire 1st Choice team, greatly appreciated by the family - we did not have to worry that mom was being sold a 'bag of goods.' Love the new windows! Noise reduction, energy efficiency, look, all just great!”

“I could not believe how fast they got the job done and how well done it was! They obviously were very careful about every detail. The house looks fantastic and everyone I talked to at the company was great to work with. The guy who did the inspection for the people who bought our house even asked us who did the siding because they did such a great job!”
