What are you really paying for in a paint job?
The paint can is almost beside the point. Our editors on what actually drives a painting budget — and where corners get cut.
The prep-first case
Surface prep — patching, sanding, caulking, washing — is most of a lasting finish. A bid that's cheap because it skips prep will peel within a year. Pay for the prep, not the brand name.
The timing case
Interior work in the trade's slow winter season catches the best crews at the best price. Save exterior jobs for dry weather — rushing paint onto a damp or cold wall guarantees a redo.
The coverage case
Two coats over primer is the honest standard; one-coat bids hide thin coverage. Confirm coats and primer in writing so a "lower" price isn't just less paint on the wall.
A paint job is only as good as the prep underneath it. Confirm coats and primer in writing, time the work to the season, and the finish will outlast a cheaper, thinner job.
