Cheapest time for exterior 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 prep-first case
The finish that lasts is built before the first coat goes on — washing, sanding glossy spots, patching nail holes, caulking gaps. Skip that and the paint releases from the wall within a season, no matter whose can it came from. A bid comes in low mostly by cutting the prep hours, so read that line before you read the brand line.
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 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 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.
