We used Rick from Window House to install windows in our home. We found him to be very knowledgeable about the product and were very happy with the installation and price. The windows he uses are KV windows(you can look them up) the quality is excellent and we couldn't be happier! My only beef was that the windows took a little longer to come and it would have been good to have a bit more communication during that time. Otherwise, all is well and if you're looking for windows I'd say give them a call :)
