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?
Strip a paint quote down and most of it is the crew's time and the surface work — the paint in the can is nearly a rounding error. What follows is where that money should actually land.
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 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
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.
Two numbers matter more than the total: how many hours go into prep and how many coats land on the wall. Get both right — real surface work, primer under two finish coats, timed to the season — and the result outlasts anything you'd save on the cheapest quote.
