Don't paint your house yourself unless you have the time, tools, skills and stamina to do the work. Depending on the size and height of your house and the condition of the existing siding, preparing and painting a house on your own can be a tedious, difficult job.

Size of Your Home An average-size house will take an average of three to four days to paint with a team of two to three people. In this case, average means a home with one to two stories and four or fewer bedrooms. A large house, such as a three-story or five-plus-bedroom home, will take five to six days.

To begin the exterior painting of a house without scaffolding, you may consider getting yourself an access platform. They come in many shapes and sizes. Some are more suited to lower-level action, and if they aren't high enough, they provide a good stable ground to combine with an extension pole.

Painting a house is not complicated, but it is time-consuming and physically exhausting. If you are pressed for time, hire professional painters. A crew of painters can finish in one or two weeks a job that might take a do-it-yourselfer several weeks or even months to complete.
