We went to their shop and walked around the showroom. First of all, they have lots of choices. We picked out the ones we wanted. They came out to measure, and they really seemed to know what they were doing (I know that is their business - they should) but we had others come out and chose to go with Windor. They are now installed, it was done quickely and clean. The house is quieter and cleaner. The windows look great, and slid like a dream. Thanks for the excellent work!!!
