Door sticks in summer but fine in winter? Put the plane down

The back door to the deck started sticking the first week of July, because it is the back door to the deck and that is what it does. Deb has developed a shoulder technique for it that I do not love watching. Gary leaned over the fence and told me to plane it. Gary tells me to plane it every summer, and every summer I do not, and every January the door quietly proves me right.

Here is the thing about a door that only sticks in the humid months. The door is the same size it was in March. Well, almost. Wood takes on moisture when the air is wet, and a solid door can pick up enough swell across its width to start dragging on the jamb. Plane off an eighth of an inch in July and you own that decision forever. Come January the wood gives that moisture back, and now there is daylight around your door and a draft you paid for.

Try the hinges before the plane

Most sticking doors are not even a humidity problem. They are a sagging problem wearing a humidity costume. The door hangs off the top hinge, the top hinge hangs off short screws in a thin jamb, and 25 years of swinging pulls the whole arrangement out of square. Summer swell is just the last straw.

1. Open the door and tighten every hinge screw you can see. Snug, not gorilla.
2. Take one short screw out of the top hinge, the jamb side, and drive a 3 inch screw in its place. It reaches through the jamb into the stud and pulls the door back up and square. Heads up: the box I bought is star drive, T25, not Phillips. The right bit comes in the box, so use that one and do not strip the head like I almost did.
3. Test the swing. Mine went from dragging to clearing with that one screw.

What went wrong

The first 3 inch screw went in at an angle because I got confident and skipped the pilot hole. Backing a long screw out of a stud you just cross-threaded is a quarter-in-the-jar situation, and it got the quarter. Learn from me. Drill the pilot.

The other 20 minutes of the overrun was me going around the house tightening the hinges on every damn door we own, none of which were on the list. The spreadsheet says I have logged this door three times since 2019. This is the first time it got written up properly.

If it sticks in January too

Then it is not the weather. Tight hinges plus a year-round stick means the door actually needs material removed, or the frame itself has moved. Planing is a fair Saturday job if you go slow and seal the raw edge after. A frame that is moving is a different conversation, and if the drywall nearby is cracking too, stop reading blogs and get a pro to look at the foundation before you sand anything.

One more thing. This same door is going to shrink in January and the latch will start rattling like a loose tooth. Different symptom, same door, same physics. Ask me about it in January.

Deb's verdict. "You fixed six doors and the one I asked about was last."
