Cheapest time for interior house painting in either city
Exterior paint needs dry weather (50–85°F), so summer is peak and priciest. Interior work has no weather limit, and winter is the trade's slow season — the cheapest time to book.
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 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.
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.
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.
