Pricing tips for exterior painting
- Scraping and priming peeling siding can take as long as painting it. Price prep from what you see, not the square footage alone.
- Add a lift or extra ladder time for third stories and steep grades.
- Offer a better option with an extra coat or premium paint. Many customers pick the middle option when they see three.
