4 windows, one picture window, one sliding door, one front door and one French door; and, save for 3 windows, all were new construction on the house I am remodeling. From the sales team (Steve Huffman), who helped me design the remodel, to the installation team (John Lynott, Ryan Hoffman, Scott Malloy and Kelly Hoffman), Andersen was professional, efficient, on time and exceeded my expectations. The installation team worked well together, were a pleasure to have around, and treated my home with respect. They cleaned after themselves and, most importantly, finished the job in the time frame that was quoted. The finished product is amazing and I can't recommend them high enough.
