Hi Jayme1: If you are stuck with keeping what you have, you can get a product to clean the aluminum frames at a hdwr or box store. Have you removed the glass and screens on any windows yet? If you do and get them back in place after cleaning them, do they move up and down? If not there are products like sill glide etc that you spread on the tracks. I noticed the wood condition above the windows and on the sills. For this kind of wear, I use Peel&Stop...I scrape all the loose paint and apply this clear product and then paint over it with a good oil base paint after filling holes etc. if screens are missing, you can buy a kit and make them for missing ones. Not too hard to do after the first couple of trys. Hope this helps.

The provia storms are very good. Price is fine, maybe a hair high if it does not include wrapping, but its a great price if it does. I agree overall with the advice provided so far on replacements vs storms, it really depends on the individual circumstances. It can be hard to justify spending that much without getting he other added benefits of replacements ( ease of cleaning, lower maintenance , potentially enhanced property value, better energy efficiency, etc), however if your existing windows can be reconditioned to the point of operating smoothly and looking good, adding the storm to that can definitely get you pretty close in those areas but with cost savings and maintaining the original integrity of the home. As wow alluded to, you could certainly take those dollars that you save and put them to air sealing , insulation , etc in other areas of he home and increase your energy savings exponentially.

That's correct, the Marvin has about 1/2" or so of visible liner , just so that the tilt latches don't gouge the wood. As mwm said, not really any such thing as a wood jamb "liner". There are woo jambs, and the liners are there to protect the wood from damage. Some products then put a wood cap over that liner in areas that don't really come into contact with moving parts. The Marvin, kolbe, and Loewen are all nice wood windows

Start with these guys and see if they have something for you that will work. https://blainewindow.com/
