Lou, did you have to order the window to fit the opening?
Not on this window. We plan on doing a re model in the future. Just got a cheap Home Depot window for $119. The rest of the house has retrofit Milgaurd windows.
It's not that bad. Was cool pulling the old weights out of the frames. I had no idea what I was doing when I changed them out but the heat savings was worth it we still do not have insulation in the walls though. Makes a huge difference in the winter.
Once you remove the window you take the measurements and subtract 1/4". It was about $250 for a window back then. Now it's about$500 a window. Glad I only have 14 windows.
