How to Price a Painting Job: A Room-by-Room Guide

Underpricing is the single most common way painting contractors lose money on a job they actually won. It usually doesn't come from bad math — it comes from skipping steps during the walkthrough and guessing at the parts that are hardest to estimate: prep work, paint grade, and how many coats a wall really needs.

This isn't a theory of pricing — it's the order most experienced painters actually work through, room by room, before they say a number out loud.

Walk each room and get wall square footage before you think about price at all. For a quick estimate, multiply the room's perimeter (length of all four walls added together) by the ceiling height, then subtract roughly 20 square feet per standard door and 15 per window.

Do this for every room separately and write the numbers down as you go, even if you're doing the whole house — lumping rooms together is where a lot of estimates start to drift from the real number.

Prep work — patching holes, sanding, taping, covering floors and furniture — is where inexperienced quotes fall apart, because it's tempting to bundle it into a single 'labor' number and hope it averages out.

Instead, walk each room and rate its prep level: light (a few nail holes), medium (some patching, minor sanding), or heavy (significant repairs, wallpaper removal, extensive taping around trim). Price each level as a multiplier on your base labor rate — heavy prep can easily double the time a room takes.

Paint cost varies a lot by grade, and coat count depends on the color change, not just the surface. A dramatic color change (dark over light, or the reverse) usually needs a full two coats no matter what the label promises — quote for that reality, not the best-case scenario on the paint can.

Once square footage, prep level, and paint grade are set, labor is just time × your crew's hourly rate. Use your own historical numbers if you have them — a rough starting point for an experienced single painter is 150–200 square feet per hour for walls in average condition, slower for heavy prep or cutting-in trim work.

Don't forget setup and cleanup time — on smaller jobs, it can be 20–30% of total time on site, and it's easy to forget when you're only counting 'painting' time.

The math above works whether you're writing it on a clipboard or building it on your phone — but speed matters. A customer who gets a clear, itemized quote the same day is far more likely to approve it than one who's still waiting three days later while they call two other painters.

This is exactly the gap Cuadrilla is built to close: itemize the quote by room right there on-site, send it over WhatsApp, and let the customer approve it with one tap before you've even packed up your gear.
