For some reason, the doors in our house make a very loud "unsticking" sound when you open them.
It's almost as if the paint isn't cured, since the sound seems to come from the contact area around the frame, where the door touches the doorframe -- but this house has not been painted in 5 years.
This loud "unsticking" door opening noise doesn't seem like a big problem, and I suppose it isn't, but since I'm a night owl, so when I open doors it tends to wake my wife up. And that's not good for ye olde marital harmony.
What can I do to make the doors in our home open more quietly without this sticking sound?
Should I somehow lubricate the frame (I'm worried that it'll collect dust or other particles and look bad)? Maybe use sandpaper to rough the paint up so it's less likely to stick?
