Why not get it done ? Cross it off the never ending chore list? It hangs over your head, and you dread doing it.. positioning them , taping etc to ensure no bugs or pollen or doggie door smells from the yard get in.. cleaning them with Lysol wipes etc to make sure you’re not breathing in black mold which can get inside them. You don’t just lift the sash, set them in and screw and done . If anyone is doing that .. congrats on Appalachia
