When you go to the home improvement store, find out how much 12 gallons of the paint you want would cost, and that will help you determine your cost. Maybe it's a low-quality paint that costs $30, in which case you're looking at about $360 for paint. If you choose high-quality paint that costs around $70, your total paint cost could be closer to $840. Professionals also recommend that you add an extra 10 or 20 percent to your total square footage, depending on the type of siding you have. Some textures require extra paint because they're rough. This is especially true with wood and stucco siding.
Protect exterior surfaces from damage by the sun, rain, wind and snow: When your house is exposed to various elements over the years, it will probably experience damage of some sort. Painting the exterior of your home can quickly fix any worn-down siding, chipped paint or anything else that needs updating. This also protects your house from those same elements for the next few years, keeping your home safe and sturdy.
