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?
Two bids on the same room can differ by half, and the gap is almost never the paint itself — it's how much prep and how many coats each one includes. Here's what separates a finish that holds from one that doesn't.
The coverage case
One-coat quotes win on price by putting less paint on the wall, and you see the difference within months as the old color ghosts through. The defensible standard is primer plus two finish coats. Get coat count and primer named in the contract so a lower number can't quietly mean thinner coverage.
The prep-first case
Most of a durable coat is what happens to the surface first: filling holes, scuffing old sheen so the paint grips, sealing seams. Premium paint over an unwashed, unsanded wall fails just as fast as the bargain stuff. Spend on the hours a crew puts into the wall, not the label on the bucket.
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.
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.

Should I choose where to live based on interior house painting cost?
