Sun, Altitude and the Boards You Choose
We work as deck builders in Kearns with one local condition always in mind: the sun. Kearns sits at about 4,530 feet on the west side of the Salt Lake Valley, and the Utah Olympic Oval in Kearns is described as the world's highest indoor oval, at 4,675 feet. In nearby Salt Lake City the average annual UV index is 5.6 and peaks around 10.4 in July, with roughly 3,000 hours of sunshine a year. For a deck, that means faster graying of wood, faster fading of cheap stains and hot board surfaces in July.
Picking a decking material for Kearns sun
Pressure-treated pine costs the least and works well under a good stain, but plan on re-staining every few years. Cedar looks warm and resists decay, yet it grays quickly if left bare. Capped composite holds color better and does not need staining, though dark colors get hot underfoot in full afternoon sun. We often suggest a lighter composite shade for south and west-facing decks, or a pergola to cut the direct light.
Shade is part of the design
A covered deck or a pergola can make a back yard usable on 95-degree afternoons. Salt Lake City averages about 23 days a year above 95 degrees. A solid roof gives full shade but has to be framed for winter snow, while an open pergola with slats or a shade sail is lighter and lets snow fall through. We talk through both and show how each attaches to your house.
A community laid out on old base streets
Kearns began on May 1, 1942, as Kearns Army Air Base, a World War II training site deactivated in 1946. After the base closed, houses went up quickly on the old roads and building foundations, and building spread west to 5600 West by the 1970s and 1980s. More housing went in around Oquirrh Park in 2019 and 2020. That gives Kearns a mix of postwar homes, 1970s and 1980s houses and a small number of recent builds. Older homes may have low back doors and small yards. Newer ones may have a slider several feet up with nothing under it yet.
Owners who stay
Kearns has a very high ownership rate. Census estimates show 83.8% of homes owner-occupied and 91.0% of residents in the same house as a year earlier. When people plan to stay that long, upkeep over time matters more than the cheapest first price. We will lay out what each material will need over ten years so you can compare honestly.

Kearns Questions
Will a composite deck get too hot in Kearns?
Dark composite boards in full afternoon sun can get uncomfortably warm to bare feet. Lighter colors, newer heat-reducing board lines and shade from a pergola or cover all help. We bring samples so you can compare in your own yard.
How often should a wood deck be re-stained here?
With strong sun at this elevation, many wood decks need a fresh coat every two to three years, and horizontal surfaces wear faster than railings. A penetrating stain with UV protection lasts longer than a clear sealer.
Can you add a deck under a high slider door on a newer Kearns home?
Yes. That is a common job on homes built around Oquirrh Park in recent years. We build a raised deck with code-height railings and stairs down to the yard, attached to the house with a flashed ledger.
Who handles deck permits now that Kearns is a city?
We check that when we prepare your plan, since Kearns changed status in 2024. We handle the paperwork either way.
