Take and pass your contractor’s certification exam. Like the licensing requirements, the content and format of the exam will vary depending on your location. However, the test will almost always include a comprehensive written section, on top of which you may be asked to describe or demonstrate key skills. Upon passing your exam, you’ll have between 1 and 4 years to complete the process of formally registering your business.
The other difficult part is getting a painting contractor to show up. While this generalization does not apply to every painter, you can rarely get a paint contractor to show up to look at the house and to later produce a written estimate. It's hardly the fault of the painting contractors; it is a combination of the contractors being smaller operations along with a high demand for their work.

Walls should be wet down before getting scrubbed, then washed with a gallon of water mixed with 1 cup chlorine bleach and 1 cup of either a concentrated, phosphate-free cleaner, such as a trisodium phosphate (TSP) substitute, or Jomax House Cleaner. Working in sections, from the bottom to the top, will avoid streaks. Be sure to rinse walls well before the solution dries. Wood siding and trim should be ready to paint after a day or two of dry weather. Westminster House Painting
