Cheapest time for interior house painting in either city
Exterior paint only cures properly in dry, 50-85°F weather, which makes summer both the only real option and the most expensive one. Interior work has no such limit, so booking it in winter — the trade's slow season — is the cheaper play.
What are you really paying for in a paint job?
Paint is the smallest line item in a painting budget — prep and labor are where the real cost sits. Our editors on where to actually spend.
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 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.
Judge a paint quote by prep and coats, not the headline number. Good prep, two coats over primer and the right season beat a cheap bid every time.
