Thanks in no small part to posters on this NG, I have overcome any fear I had of disassembling and repairing the windows in my house... got everything in pretty good shape except one of the windows in the kitchen. All windows are Anderson Narroline windows, most circa 1989 but the one that I had problems with was dated earlier than that, 1984 I think? Anyway, both sashes were stuck and there was no screen on this window, which was above the kitchen sink - one that you just might want to open. So I forced it open and found a bottom sash rotted along the lower edge. D'oh. I bit the bullet and ordered two new sashes from Andersen in Low-E glass as well as a screen (the upper sash was badly stuck, and this was the only window in the house that was not "High Performance" or "Low-E" glass anyway.) They arrived today and installed without a hitch, but the upper sash stuck again as soon as I put the sash channel back in the left side of the window. I'm guessing that either a) I need a new sash channel b) I should shave a little wood off the frame to allow a tiny bit more clearance for the sash channel, or c) I should lube the sash channel with something.
I'm guessing that something like a teflon spray would be appropriate? I don't think I want to use anything greasy on wood. Will this really help, or do you think I'm looking at options a) or b)?
Also, I think I may have created more work for myself. I ordered the window in white exterior and unfinished interior as that's how the rest of the windows in the house are. However, someone went back and painted the inside of all the sashes and trim gloss white. Now that I look closely at the windows it looks like the exterior surface is just wood with a really hard, smooth coat of white paint on it. True? Should I just have ordered all white windows and saved myself the trouble of painting? Should I paint the sashes installed or removed?
thanks,
nate
(all other windows working nicely, thanks...)
