Looking for any advice for replacement windows and how to buy the right windows so that I don't have to replace a bunch of drywall or casements or do any major exterior cutting or filling..... The house I have was built back in 1964 and it has these windows that look like double hung but they are not they have a horizontal lever that you pull and the bottom half of the window swings out. These windows have seen their better days and I've replaced windows in the past but hap-hazzardly.... I'd like to know what is the correct way to measure the windows so that I can find the right size or have custom ones made that just go right in without much work inside or out. I've heard sliders are bad windows so I'm thinking of just normal double hung. I'm on a budget so I'd be looking at keeping the cost down. Here is a link to pictures of the front of my house ..... http://www.iw.net/~kswan/House/ I am preping the house for a re-paint and while I'm at it I wanted to put some new windows in. Like I said the current ones have seen their days, they are only single pane and we always have ice build up during the winters and then mildew problems, etc.... Any advice would be apprecaited.
