We have purchase new energy effiecient windows from Tom Adams. The sales person came to our home and was very infiormative and not pushy like two other companies that I will not mention. We compared prices and Tom Adams was similiar and in one case less money. But they had the Best Warranty and reputation ( 35 years ago my parents used them) Well everything is in and my house seems warmer and quiet. I don't her my neighbors dog, anymore. We are very Happy. I did have one problem, which in 2 days a repairman came out and fixed at no cost. Like I said, we're very happy with our chose.
