How does one determine the CORRECT spline size when replacing screens? In my area three sizes are available. I picked the middle sized one because it matched what came out of the screen. However, it was pretty hard to set the new spline into the groove. I'm using aluminum screens and new frames. There must be a way to determine the right size. Even the large diameter will press into the groove. Would the small size be adequate to hold the screen??? :)

:confused: I am moving into my dad's house, and he has given me various home improvement tasks. The major one is my room: new window, closet, flooring, and paint. I am tackling the window first. He also wants to replace two other windows in the house. Money is not the first concern, the value is. Are there windows that increase the value of the house? I would like to get an idea of what is involved in the window replacement. Is this something that can be done without professional installation? Should I have someone come in to give me an estimate, but really just pick their brain? Any advice would be GREAT!
