I am very happy with CustomExchange, their services and product. I was shopping around for replacement the windows for my home. I have recieved quotes from local and big windows stores. I was hestiated after I got the quite from CustomExchange. Something too good to be true, the discount was deep, and i think i could not go wrong with the price and decided to try it out. Micheal came and gave me the straight quote, no dancing around, and very honest, nothing like selling you a used car. After two weeks, the windows came, and took 1 day to install all 6 windows. I am very happy with their services, prices, products, and very surprisingly, when I paid him the last installment, he gave me the life time warrany card on their product and told me to contact him if have any problem. I would suggest if you want to replace your single pane windows, get a quote from the local store and compare with CustomExchange, if you are smart consumers, you will do what i did ,and go with them.
