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?
Most of a paint quote is labor and prep, not paint. Our editors on where the money should go.
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 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.
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.
A low bid usually buys you less prep and one thin coat, which reads as savings right up until the wall starts showing wear. Ask what surface work is included and how many coats you're getting before you line the totals up against each other.
