I took three bids from different companies, including Champion. Durante was not the highest ($6,000), nor the lowest bid ($3,600). The in-home presentation of Durante's products was clear, polite, and demonstrated several advantages in the manufacture of "Sunrise" windows, in particular the more narrow profile compared to other vinyl windows. I was given a six to eight week time frame for the follow-up measuring, and then the installation. The measurer came in about three weeks, and the installers came right at six and a half weeks. The installers worked very efficiently, replacing one window at a time during cold weather. The installation was straight forward and of high quality workmanship. The installers did a good job of taking care of the interior of the house, as well as cleaning up in the yard outside when they finished. The windows look great and give a brand new feel to our old sun room. Overall I would give Durnate and their crew an A+ for their work from start to finish. I would recommend them to others, and I will use them again myself.
