Painting Estimate: What to Include, Mistakes to Avoid, and How to Write One From Your Phone

By Frank Flores · Updated September 2026

If you paint homes or businesses, the estimate decides the job before you open a single can. Most customers compare two or three painting estimates side by side, and the one that looks more professional usually wins: broken down, easy to read, with the terms in writing. It does not have to be the cheapest.

A solid painting estimate is priced by square foot or by room, keeps labor separate from materials, and says in writing how many coats are included. That protects you, and it gives the customer a reason to trust you.

Good painters lose jobs to the "I can do it cheaper" guy all the time. Most of the time it is not the price. It is that the other painter sent something that looked more serious. An estimate with every line, the number of coats spelled out, and your business name on top wins even when you charge the same or more.

What to include in a painting estimate

• Surface prep. Washing, sanding, patching cracks and nail holes, caulking and taping. A lot of arguments start because prep was never written down.
• Paint and materials. Brand and product line, number of coats included, and primer if the job needs it.
• Labor by area. Price per square foot or per room, with interior and exterior listed separately.
• Work at height. Tall ladders, scaffolding or second story walls. Charge for the extra time and the risk.
• Trim and details. Baseboards, crown molding, doors, frames and closets, each as its own line.
• Protecting the space. Plastic, drop cloths, masking and moving furniture. That time costs money.
• Final cleanup. Hauling off empty cans and leftover materials, and leaving the area clean.
• Valid until date and payment terms. How long the price holds and how much you ask up front as a deposit.

Sample painting estimate lines

Here is how a simple interior job might look once it is broken down. These are example numbers only. Use your own prices for your market.

Below the lines, add a short note for anything that is not included, like ceilings, drywall repair beyond small patches, or moving heavy furniture.

Painting estimate mistakes that cost you money

• Guessing instead of measuring. Square footage is your best defense when the customer says the price is too high.
• Not stating the number of coats. A second coat "on the house" eats your profit.
• Texting a single number with no breakdown. It looks informal and invites haggling.
• Leaving out your markup on materials. If you buy the paint, your time driving to the store counts too. Build it into the price.

How to write a painting estimate from your phone

No computer and no typing needed:

1. Open Chambaly and tap the microphone.
2. Describe the job out loud. "Paint living room, dining room and two bedrooms, 850 square feet at 1.25, two coats, includes patching, 8 gallons of paint at 42.50, 30% deposit." Talk to it like you would talk to a helper.
3. AI builds the lines. It splits labor and materials, and if you did not give a price it suggests one and flags it for you to check.
4. You review and adjust. The price is always yours. Your markup on materials stays inside the price and only you see it.
5. Send it by text, WhatsApp or email. The customer gets a clean PDF with your business name, every line, the deposit and how to pay you.

Why a detailed estimate works

• You win the comparison. When your estimate sits next to someone else's, yours looks like it came from a real company.
• You lock in the scope. Coats, prep, which rooms: all in writing. No more "I thought the closet was included."
• You answer while the customer is still interested. Sending the estimate while you are still at the house beats sending it next week.
