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?
The paint can is almost beside the point. Our editors on what actually drives a painting budget — and where corners get cut.
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
Surface prep — patching, sanding, caulking, washing — is most of a lasting finish. A bid that's cheap because it skips prep will peel within a year. Pay for the prep, not the brand name.
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.
Judge a paint quote by prep and coats, not the headline number. Good prep, two coats over primer and the right season beat a cheap bid every time.
