Hired a pro to paint interior and exterior of my house. It was new construction. Outside is approx. 50% board and batten, also had cedar beams inside and out on porches. Outside was 3000 and inside was 8000. this included prime and paint all base, doors, closets and cabinets. All paint and stain was Sherwin Williams, high quality stuff. I highly recommend getting pros you dont have to bird dog and punch over and over! May cost a little more initially, but you'll be alot happier with the results!!
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.
"Rafael was very professional, detail-oriented, pleasant to communicate with (responds promptly, returns calls, confirms appointments) and always showed up on time. He painted my daughter's room beautifully and for a reasonable price (offered pricing with and without paint). His work was precise and without mess. I will definitely hire him again for more painting projects."
