The Estimate That Almost Cost Me a Crew Member<\/h2>\n

A painter I know, Carlos, told me about a job that changed the way he estimates forever. It was a 2,400 square foot colonial in a nice neighborhood. The homeowner wanted the entire interior repainted. Carlos walked through, did some quick math in his head, and quoted $4,800. The homeowner said yes on the spot. Carlos should have been suspicious.<\/p>\n

Three days into the job, they discovered that the previous paint was an oil-based enamel that had been applied over wallpaper adhesive residue. Nothing stuck. Every wall needed to be sanded, primed with a bonding primer, and then painted with two full coats. The ceilings had a heavy orange peel texture that ate paint like a sponge. The trim was six-panel doors throughout, which take three times as long to cut in as flat doors.<\/p>\n

Carlos ended up spending 40% more on labor and 30% more on materials than he estimated. After paying his crew, he made about $3.50 an hour on that job. His best guy, Marcus, told him he could make more at a car wash and almost quit.<\/p>\n

The problem was not that Carlos is a bad painter. He is excellent. The problem was that he estimated the job the way most painters do: a quick walk-through, some rough mental math, and a number that “felt right.” He did not have a system.<\/p>\n

This guide is the system. Seven steps, each one designed to catch the surprises that eat your profit. Whether you are a painting contractor, a GC who subs out paint work, or a handyman who takes on interior painting, this process will help you estimate paint jobs accurately, bid with confidence, and protect your margin.<\/p>\n

WHAT THIS GUIDE COVERS<\/div>\n

A complete 7-step system for estimating any paint job<\/strong>, from initial measurement through final markup. Includes real coverage rates per gallon, labor production rates by surface type, a complete sample estimate worksheet for a 2,000 sq ft house, and the prep work pricing that separates profitable paint jobs from money losers.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Step 1: Measure Every Surface<\/h2>\n

Measurement is where most estimating errors start. Not because contractors cannot measure, but because they skip surfaces, forget to deduct openings, or estimate room sizes instead of actually measuring them. In paint estimating, precision in this first step drives the accuracy of everything that follows.<\/p>\n

Walls<\/h3>\n

Measure the perimeter of each room and multiply by the ceiling height. This gives you gross wall area. Then deduct the area of windows and doors.<\/p>\n

For example, a room that is 14 feet by 12 feet with 9-foot ceilings:<\/p>\n
