means The wooden fittings of a house (moldings, doors, trim) — and by extension, the hidden margins someone emerges from when they suddenly reappear.

from Straightforward compound of 'wood' + 'work,' meaning things crafted from wood, in use since at least the 1600s for household carpentry. The idiom 'crawl out of the woodwork' arrives much later, borrowed from the image of insects — termites, cockroaches — hidden inside a house's wooden structure who suddenly swarm out when disturbed; the phrase caught on because it captures that same faint creepiness of people appearing from nowhere, as if they'd been living in the walls the whole time.
