I’m very happy to report that all 10 of my doors, which have all gone through at least one complete heating and cooling season, have not moved at all. No sticking after this incredibly hot and humid summer. Even the bathroom door, which takes the most abuse from shower humidity, and even though every knot has checked and every joint opened slightly – the only one that did that. It still opens and closes smoothly.
I have to attribute that to double coating the top and bottom with BIN shellac primer and caulking the panels before painting. It’s so important to seal all 6 sides of a door and yet hardly anyone does it. At least in the trades.
My goal installing them was 1/16th gap on the top and sides and 1/4" off the floor. I was more or less successful there, which makes the whole non-movement thing even that much more noticeable. I don’t mean to toot my own horn but I’m pretty darned pleased with the results. :-)
