Can someone advise me on service/repair of Pella "roll screen" windows?
I'm in a brick ranch built in 1960 with Pella wood casements. The screens work, but rather rough when rolling them up or down. I'd like to get inside the mechanism and clean/lube if necessary. There is a "box" at the top of each window (metal) and i suspect the roll mechanism is in there somewhere, but I don't see any easy access. The side tracks are straight and in good shape.
Please don't tell me I have to remove the trim, etc. (OK tell me!)
Any/all replies appreciated.
