The door needs a shoulder in August and closes politely in February. Removing a little wood feels obvious until you remember that February will return.

Look at the whole opening

Record the rubbing point, hinge condition, gaps, and whether nearby doors behave similarly. The US Forest Service Wood Handbook explains how moisture changes wood dimensions. That makes humidity a plausible contributor, not proof that every sticking door is harmless.

Match the symptom to the next check

Observe gently; do not force the door closed

Take one photo of the whole opening and one of the contact point. These observations choose the next investigation; they do not prove that seasonal swelling is the only cause. Keep new cracking, widespread misalignment or a sudden change in the structural assessment below.

Read the rub and the gaps together

For a week, record date, room humidity, rub location and whether the latch works without lifting the handle. Use the same hygrometer position away from the bathroom plume or open window. The Wood Handbook explains moisture-related dimensional change; your diary helps separate a seasonal pattern from a sudden failure. Check strike alignment when the door closes freely but will not latch.

Keep the remedy proportional to the evidence

A carpenter can assess alignment and permissible trimming for the particular door. Do not trim a fire-rated or specialist door casually; its construction and requirements matter. If the binding is new and accompanies cracking, sagging, water damage, or several distorted openings, investigate the underlying condition instead of repeatedly shaving the symptom.

Before the next step

  • Photograph the gaps and exact rubbing point.
  • Compare the symptom across seasons and nearby openings.
  • Confirm door type and allowable alterations before cutting.

Start with the rubbing point and the hinges, and tell the carpenter whether the door behaved this way last summer. That small bit of history can save wood you may want back in February.
