When Was the Last Time You Painted Your Exterior Both residential and commercial property needs refreshing from time to time. One of the easiest ways to keep your exterior looking great is with a new paint job. Depending on the weather conditions, environmental conditions, the quality of your paint job, and the quality of the paint you use, your exterior should be painted every 7 to 15 years. However, time can easily pass without realizing that it has been years since you painted. It seems like suddenly you realize your exterior is looking shabby. in Public bookmarkswith exterior-paintingby 2 users
