Utah’s Wasatch Back offers breathtaking scenery, but its climate can be brutal on your home’s exterior. Between intense UV exposure at higher elevations, wide temperature swings, and long snow-packed winters, your exterior finishes are under constant stress. So, how long can you expect your exterior paint or stain to last before it’s time for a refresh?
On average, high-quality exterior paint in Utah can last 7 to 10 years on vertical surfaces when properly prepped and applied. However, that timeline depends heavily on the quality of the substrate, product, and exposure. South-facing elevations, for example, take more UV damage and may need attention a bit sooner.
Stain, especially transparent or semi-transparent finishes, typically needs more frequent maintenance—every 3 to 5 years, depending on exposure. Stains don’t form a thick film like paint, so they’re more susceptible to moisture intrusion, UV breakdown, and general wear.
If there’s one area where Utah’s climate really takes a toll, it’s horizontal surfaces like decks, railings, and stair treads. Snow tends to sit for long periods, melting slowly and seeping into the wood. Freeze-thaw cycles can wreak havoc, especially on stained surfaces. Even a top-tier deck stain may only last 1 to 2 years before it starts to show signs of fading, peeling, or water absorption.
The key to maximizing the life of your exterior finishes? Regular maintenance. Annual inspections in the spring can help catch issues early—like cracking, peeling, or fading—before they become major problems. Touch-ups, re-coats, or even a fresh clear coat can extend the life of your investment and keep your home looking beautiful year-round.
