Cheapest time for exterior house painting in either city
There's a hard weather floor for exterior work (50-85°F), which crowds all that demand into summer. Interior jobs dodge that limit, so winter — when painters are otherwise slow — is when they cost the least.
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
A quote that promises 'one coat, done' is usually promising a thin film that telegraphs whatever was underneath. Primer and two finish coats is what holds the color and buries the old wall. Put both in writing; otherwise the cheaper bid is just less product spread further.
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 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.
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.
