Cheapest time for interior 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 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 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 headline price on a painting bid tells you almost nothing — ask about prep and coat count instead. Two coats over primer, done in the right season, consistently outperforms the cheapest quote.
