My wife and I hired DunRite Windows and Doors to replace the sliding door on our 1960's ranch. It was important to us that the product compliment the original aesthetics of the home, but also have the energy-saving characteristics of modern materials. Saul researched various product lines from an array of manufacturers, then came to our home and shared his findings in person. (He brought samples so we could see first-hand the various materials used.) He was professional, friendly and knowledgeable. He took accurate measurements and made special notes to the installers to preserve the original interior trim, per our request. We placed our order for an Ambassador Series 8900 sliding door. It took a couple of weeks for the door to be built by the manufacturer. (It was custom-made for proper fit.) Once complete, the installers came to our home. They were professional, friendly and tidy. They put down tarps to protect our floors. They removed the old sliding door and assembled/installed the new one in under 2 hours! They removed all the debris and cleaned the area. The door was properly insulated and caulked, and it looks great and works perfectly. I would not hesitate to recommend DunRite Windows and Doors to family and friends--They do great work. In fact, my wife and I were so delighted with the results, a little over a week ago we placed another order with them to replace all the windows in our home!
