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?
Most of a paint quote is labor and prep, not paint. Our editors on where the money should go.
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 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
Book interior rooms during the slow winter stretch and you get first-string crews without the summer premium. Outside work can't be pushed against the weather: wait until the siding is dry and temperatures hold, or the coat fails to bond and the whole wall comes back around.
Don't shop a painting quote on price alone — shop it on prep and coat count. Get those two right and the season timed correctly, and the result beats a bargain bid every time.
