Cheapest time for interior house painting in either city
Summer's exterior-painting rush is really a weather requirement, not a preference, and prices reflect it. Interior work has no such requirement, making the trade's quiet winter months the cheapest time to book it.
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 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
Winter is dead season for interior painters, and the good crews will take your rooms then at a rate they won't quote in July. Exterior work runs the opposite calendar — it needs dry, mild days, so hold it for spring or fall. Paint rolled onto a cold or damp wall never cures right, and you end up paying for the job twice.
The headline price on a painting bid tells you almost nothing — ask about prep and coat count instead. Two coats over primer, done in the right season, consistently outperforms the cheapest quote.
