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?
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
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.
Where a crew spends its hours decides how the job ages: sanding, patching and caulking up front, then full coats over primer. Time the interior work for winter and the exterior for dry weather, and the finish holds for years instead of months.
