We had the Kelemer Bros. replace our back door and found them to be completely professional and wonderful to work with, from start to finish. Their installer was on time, pleasant, and meticulous about his work. He even cleaned up thoroughly afterwards. We highly recommend doing business with KB!

I am so grateful for Joe and his guys. From Joe’s first phone call to to last goodbye it was complete professionalism. When the crew came in to replace the windows everyone was very nice and respectful and made… sure the house was clean when they left. Joe came back, did a final walk through to make sure everything was perfect. Thank you so much for all your hard work!
