How Long Does Exterior Paint Really Last?
In the Black Hills, your home’s exterior takes a beating. From scorching summer sun to heavy snowfall and rapid temperature swings, the local climate is tough on paint. Homeowners often ask: How long should my exterior paint really last? The answer depends on a few key factors, including paint quality, prep work, and weather conditions.
At Black Mountain Painting, we’ve painted countless homes in this region — and we know how to extend the lifespan of exterior paint so your home stays protected and beautiful year after year.
