Cheapest time for interior house painting in either city
Summer is peak season for exterior painting because the weather demands it, and prices follow demand. Interior painting isn't weather-dependent at all, which makes it the cheapest job to book in a slow winter month.
What are you really paying for in a paint job?
A painting bid can look cheap and still deliver a bad result, because the number rarely reflects the prep behind it. Here's how our editors think about it.
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 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 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.
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.
