Interior Painting Cost: Materials vs Labour

Use the Paint Calculator for walls (and a separate ceiling calculation). Two coats and realistic coverage matter more than buying the cheapest tin.

Primer on new drywall or stained surfaces is an extra product line — do not bury it inside ‘paint’ if you want comparable quotes.

Prep (filling, sanding, caulking), masking, cut-in quality, ceiling work, and furniture moving often dwarf the cost of the paint itself in a contractor quote.

Empty rooms paint faster than furnished ones. High trim detail slows the job.

Enter materials in the Cost Estimator, then add a labour allowance if you have an hourly or per-room quote. Keep a contingency for repairs that appear once old paint comes off.

National averages for ‘cost per square foot to paint’ hide prep differences. Prefer itemised scope.

DIY saves labour but costs time and risk of visible lap marks. Hiring makes sense when ceilings, stairs, or colour changes need experience — still use your own gallon count to check the material line.

If you DIY, budget primer, tape, drop cloths, and a second ladder day. Consumables are easy to forget when comparing a ‘paint only’ estimate to a full contractor quote.

For rental or resale timelines, labour speed often outweighs the gallon savings — decide with the calendar, not only the tin price.
