well I have about a 20 year old house. the windows arnt horrible, but id like to put something more efficent in. What are your guys opinions on replacement windows?? theres alot of companies near me (madison, WI) that offer decent deals to install the windows. You have to purchase their windows though. I have a couple concerns about this.
I belived i could do the replacements myself, but if they install em for free.. then let em. does anyone have any insight in this?
