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
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
A quote that promises 'one coat, done' is usually promising a thin film that telegraphs whatever was underneath. Primer and two finish coats is what holds the color and buries the old wall. Put both in writing; otherwise the cheaper bid is just less product spread further.
The timing case
Winter is dead season for interior painters, and the good crews will take your rooms then at a rate they won't quote in July. Exterior work runs the opposite calendar — it needs dry, mild days, so hold it for spring or fall. Paint rolled onto a cold or damp wall never cures right, and you end up paying for the job twice.
The headline price on a painting bid tells you almost nothing — ask about prep and coat count instead. Two coats over primer, done in the right season, consistently outperforms the cheapest quote.
