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 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
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.
Where a crew spends its hours decides how the job ages: sanding, patching and caulking up front, then full coats over primer. Time the interior work for winter and the exterior for dry weather, and the finish holds for years instead of months.
