Zohar replaced 6 windows for us. We are delighted with his work. He came one evening, measured the windows, discussed what we wanted and gave us a firm quote. Because he was well recommended, and the price was fair, we agreed on the spot. He came promptly at the date and time specified, along with a helper. They were in at 8:00am and out at 2:30pm. He left the house in immaculate condition. The retro-fit windows look wonderful. I would recommend Casper Windows to anyone.
