Recent Park City Project

A covered Trex deck with mountain views in Park City.

This Park City project is a covered deck that wraps a mountain home, built with Trex Transcend Lava Rock composite decking and custom ornamental railing in a horizontal bar pattern that keeps the view open. The covered section has a finished soffit with recessed lighting, and there is room for an outdoor dining area, a grill, and a fireplace lounge.

Why Blackrock

Why Park City homeowners choose Blackrock Decks.

Built for Park City's weather

Park City sits near 7,000 feet, with heavy snow in the winter and strong high-altitude sun in the summer. Composite decking like Trex handles the snow load, the freeze-thaw cycles, and the UV without the sanding, staining, and splinters that come with wood, and a covered section keeps part of the deck usable even when a storm rolls through.

Good to Know

Building a deck in Park City: common questions.

Does Blackrock Decks build decks in Park City, Utah?

Yes. Blackrock Decks builds custom decks, patio covers, pergolas, custom roofs, and railing in Park City and across Summit and Wasatch Counties, including Snyderville, Kimball Junction, Jeremy Ranch, Heber City, and Midway.

Can you build a covered deck in Park City?

Yes. Covered decks and custom roofs over decks are some of the things we build most. The cover can include a finished soffit, recessed lighting, and ceiling fans, so the deck stays comfortable and usable through more of the mountain year.

How much does a custom deck cost in Park City?

Every Blackrock deck is uniquely priced based on your home and project, so we don't offer a flat price list. Factors like deck size, material line, height, stairs, railing, and additions such as a roof or lighting all influence the final cost. We measure your space and provide a no-cost estimate tailored to your project.

Do I need a permit or HOA approval to build a deck in Park City?

Permitting requirements vary by project, and some neighborhoods have HOA rules about design and materials. As a licensed general contractor, Blackrock Decks handles the full scope of your project, including permits and engineering, so you don't have to sort it out on your own. If you have an HOA, mention it when you request your quote.

What decking holds up best to Park City's snow and sun?

Composite decking like Trex resists the heavy snow load, freeze-thaw cycles, and high-altitude UV that wear out a wood deck in Park City. Composite decking typically lasts 25 to 50 years with basic care, roughly double the 10-to-15-year lifespan of a wood deck, with no yearly sanding or staining.

What warranty comes with a Blackrock deck?

Every project we build carries our five-year Blackrock Decks labor and craftsmanship warranty. All materials are warrantied by their manufacturer, and as a TrexPro Platinum installer, your Trex project can qualify for additional manufacturer warranty coverage.
