At least 90% of painting time goes into setup, prep work, and priming. The method of prepping required varies for each type of exterior material on the home, but every project must be patched and cleaned. The more thoroughly you prep and prime your home’s exterior, the longer your paint job will last. You could save quite a bit if you do this part yourself, but it must be done correctly, or your contractor will have to go over what you missed. The prices mentioned are based on paying a contractor to do each job rather than one overall quote for the work from start to finish.
Remove any outlet covers or lighting fixtures (if possible). Then scrutinize the walls for any defects. Simply fill them in with caulk or spackling compound if you encounter cracks, dents, or holes in your walls and trims. There are also tips and tricks for filling nail holes. Once done with the repair, smoothen the wall down with sandpaper and then wipe it with a damp sponge.
Even if you hire a professional, you may need to play a small role in your house painting process. This could be anything from moving your furniture to the center of the room to removing switch plates and outlet covers. Ask your painter how much prep work is expected of you before hiring. The amount of work you’re willing to do could help you narrow down the right painter for the job.
After you have done the multiplication, subtract about 40 sq feet per window, and about 60 sq feet per door. Divide by 400 (interior paint covers 400 sq feet per gallon). The number that remains, is how many gallons you will need. If doing multiple wall colors, then you should do this process for each room (or sets of rooms) with a particular color. 
Having a professional paint your home from top to bottom, inside and outside has a number of advantages. For one thing, it'll save you a ton of time by not having to do the work yourself. In addition, you won't have to be concerned about safety issues, such as climbing a ladder to paint your house's gutters. Best of all, you can expect a clean, attractive finished product from a professional painter.

One important consideration when comparison shopping for interior paint is the manufacturer’s available palette. One brand of latex paint may be significantly less expensive than others, but the tint options can be limited. There can also be a noticeable difference between one manufacturer’s “midnight blue” and another’s “Prussian blue.” There is no universal standard, so this is why sample cards and test paints are so important.
Power washing – $0.42–$1.40/sq. ft.. You might think you can save some money by power washing the exterior yourself, but homeowners can get a bit trigger-happy with a power washer in their hands. The pressure from the washer can take them unawares, breaking windows, leaking water into window frames and siding joints, and gouging wood. It’s probably wiser to use a hose and scrubbing brush. Rinse off any cleaning solutions thoroughly.

Expect to pay between $600 to $3,500 or $1.25 to $3 per square foot to coat vinyl, with prices likely increasing for the finish. It is one of the more inexpensive siding materials to have repainted, especially with recent innovations in materials. Changing the finish on your siding is not recommended unless it's completely degraded and worn away by the weather.
