5383 actual square footage of walls. Do not estimate or accept estimates based on square footage of floor. I use a laser device to ACCURATELY measure. I take out for windows and doors. Unless a job is new construction (empty), understand that furniture,artwork, carpet, appliances, etc. will affect time and labor. Also understand that ceiling height is a game changer. A rate of no less than $1.80/sf including materials is realistic, acceptable and more than fair for a qualified professional to paint rooms with 9' ceilings. Expect to pay $1 extra per square foot for 9'- 15' and $2.50 extra for 15' +. Some additional costs for extreme conditions will raise that amount. Trying to base the amount on days worked by number of workers is both unfair to the professional and undue to your senses. This job is based on 15 days work by two workers, one painter and one grunt to tarp, move furniture, clean up and book paint. That nets to approx $663/day. As you can see, not great wages.
"I needed to get my house painted quickly and professionally to get it ready for the market as soon as possible. Mr. Corzo responded immediately to my need for an estimate and arrived that day. He offered a fair estimate to paint the entire interior and exterior of my home. Job was completed in estimated amount of time and to my satisfaction. Walter does great work and I would recommend him without hesitation. He was on time, courteous, professional, and an excellent painter,"
Regarding cost - Keep in mind some older homes may cost more due to the EPA RRP lead paint rule that was placed in effect. I'm not saying price will be doubled, but it will add some more labor and material cost. After all, the EPA is fining non compliant contractors nearly $38,000 per non compliant violation. I see many posts about illegal contractors. We do pay insurances, we have business costs, I price jobs to where I am comfortable with paying labor, expenses for my business, and not making $250k per year as some do. I have gone into homes where someone thought they were getting a great deal and ended up calling me to fix mistakes or sloppy jobs. Paint will vary in cost, yes.
