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 coverage case
A quote that promises 'one coat, done' is usually promising a thin film that telegraphs whatever was underneath. Primer and two finish coats is what holds the color and buries the old wall. Put both in writing; otherwise the cheaper bid is just less product spread further.
The prep-first case
The finish that lasts is built before the first coat goes on — washing, sanding glossy spots, patching nail holes, caulking gaps. Skip that and the paint releases from the wall within a season, no matter whose can it came from. A bid comes in low mostly by cutting the prep hours, so read that line before you read the brand line.
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.
Don't shop a painting quote on price alone — shop it on prep and coat count. Get those two right and the season timed correctly, and the result beats a bargain bid every time.
