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?
Paint is the smallest line item in a painting budget — prep and labor are where the real cost sits. Our editors on where to actually spend.
The coverage case
One-coat quotes win on price by putting less paint on the wall, and you see the difference within months as the old color ghosts through. The defensible standard is primer plus two finish coats. Get coat count and primer named in the contract so a lower number can't quietly mean thinner coverage.
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
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.
A paint job is only as good as the prep underneath it. Confirm coats and primer in writing, time the work to the season, and the finish will outlast a cheaper, thinner job.
