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?
A painting bid can look cheap and still deliver a bad result, because the number rarely reflects the prep behind it. Here's how our editors think about it.
The coverage case
Two coats over primer is the honest standard; one-coat bids hide thin coverage. Confirm coats and primer in writing so a "lower" price isn't just less paint on the wall.
The timing case
Interior work in the trade's slow winter season catches the best crews at the best price. Save exterior jobs for dry weather — rushing paint onto a damp or cold wall guarantees a redo.
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.
