We are getting ready to pull the trigger and replace the windows in our home. We just moved into a 40 yr old house and the windows are crap. They are single pane aluminum windows that I suspect are original to the home. They are falling apart and need to go.

We have received several estimates and the windows them selves seem to be very similar. The biggest difference is going to be the installation.

I live in North Texas so weather is not as extreme as elsewhere. We have hot summers and some what cool/cold winters. What are the things I need to be watching for when they install my windows? Do they need to put insulation around the frame or is chalk sufficient? I have never installed windows before so I really do not know what to look for.
