Exterior painting is essential to preserve the life of the wood or other substrate your house is composed of. Typically we recommend painting the exterior every 5-6 years to stay ahead of any significant peeling or wood rot. However, you can wait 8-10 years between paint jobs as long as your home isn't exposed to prolonged moisture or sun exposure. Once you start noticing peeling in areas, color fading, or a few boards that look relatively dried out; it’s probably time for a re-paint.
