What affects exterior house painting cost the most?
Painting a home's exterior — siding, trim and prep. Sun and weather exposure affect how long the finish lasts. Grade of equipment and materials tops the list, followed by home size and complexity, local labor, and the cold climate zone.
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
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 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
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.
