Carpentry

Why wood moves, how walls stand up, and why the bedroom door sticks every July.

Wood is the one building material that keeps changing after it is installed. It swells in August and shrinks in January, and most of the small mysteries of an older house (sticking doors, gapping floors, a drawer that binds) come back to that. These explainers cover the moisture story, how a stud wall carries its load, and how a door is hung.

Where the line is

Yours, and theirs. Tightening hinges, trimming a door edge, hanging shelves on studs: homeowner work. Removing or cutting into any wall that might be load-bearing, notching studs or joists, or anything structural: a permit and a structural engineer or licensed contractor.
