Cheapest time for interior house painting in either city
Because exterior paint needs warm, dry conditions, summer bookings are unavoidable and pricier. Interior painting sidesteps that constraint entirely — schedule it in winter, when crews have far less competing work.
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
Most of a durable coat is what happens to the surface first: filling holes, scuffing old sheen so the paint grips, sealing seams. Premium paint over an unwashed, unsanded wall fails just as fast as the bargain stuff. Spend on the hours a crew puts into the wall, not the label on the bucket.
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 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.
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.
