The short answer

In Utah County in 2026, a professionally built deck typically runs $35 to $55 per square foot for pressure-treated wood and $55 to $85 per square foot for composite, installed, with a basic railing. A typical 300 square foot composite deck lands in the $17,000 to $26,000 range; the same deck in wood runs roughly $11,000 to $17,000. Steel railings, stairs, a second-story height, a roof or pergola, and lighting all add to that.

These are typical ranges from the decks we build and quote across Utah County, not a price list. Every lot is different. The only accurate number is an itemized quote after we walk the site, and that consultation is free.

What moves the price

  • Height. Ground-level decks are the cheapest to build. Once a deck is more than a few feet up, posts get bigger, footings get engineered, and stairs get long. A second-story deck can cost 15 to 30 percent more than the same footprint at grade.
  • Decking material. This is the biggest line item. Pressure-treated pine is cheapest; cedar is mid; composite and PVC are the most expensive up front and the cheapest to own.
  • Railing. A basic wood railing is included in the low numbers above. Aluminum, cable rail, glass, and custom steel each step up from there. Railing is priced per linear foot, so a long, skinny deck has proportionally more railing than a square one.
  • Shape and pattern. Rectangles are efficient. Angles, curves, multiple levels, picture-frame borders, and diagonal decking all add labor and material waste.
  • Site and access. Steep lots, rocky soil, tight side yards, and anything that keeps a skid steer out of the back yard add labor. Alpine and Draper hillside lots see this more than flat lots in Lehi or Saratoga Springs.
  • Extras. Lighting, built-in benches and planters, outdoor kitchens, privacy walls, and a roof or pergola are all add-ons that are easy to price as separate line items.
  • Permits. Most Utah County cities require a permit for attached decks and anything over about 30 inches. Fees are typically a few hundred dollars. We handle the application and inspections.

Composite vs. wood: the ten-year math

A wood deck costs less on the day it's built, but Utah sun and snow are brutal on wood. Expect to stain or seal every one to two years, and expect boards to cup, check, and splinter over time. Over ten years, the maintenance on a wood deck often adds up to the price difference, and you still have a wood deck at the end of it.

Composite costs more up front and then mostly leaves you alone: no staining, no splinters, no rot, and a 25-year or longer warranty from the major brands. If you plan to be in the house a while, composite usually wins. If you're selling in a year or two, wood may make more sense. We build both and will tell you which fits your situation.

Why our railings change the math

Most deck builders order railing from a catalog, and aluminum or cable railing from a catalog is fine. We fabricate and powder-coat custom steel railings in our own shop, which means a railing that fits your deck exactly, a look you can't get off the shelf, and no middleman markup. On a deck, the railing is what you see from inside the house every day; it's the upgrade that changes how the whole thing looks.

Deck cost FAQ

How much does a 300 sq ft composite deck cost in Utah County?

Most 300 square foot composite decks we build land somewhere in the mid-teens to mid-twenties of thousands, depending on height, railing, stairs, and the decking line. A ground-level deck with a simple railing is at the low end; a second-story deck with steel railing, stairs, and lighting is at the high end.

Is composite worth the extra cost over wood?

Over ten years, usually yes. Wood costs less up front but needs staining or sealing every one to two years in Utah sun and snow, and boards start cupping and splitting. Composite costs more on day one and then costs almost nothing. If you plan to stay in the house, composite tends to pay for itself.

Do I need a permit, and does it add cost?

Most Utah County cities require a permit for an attached deck or any deck over about 30 inches off the ground. Permit fees are typically a few hundred dollars, and we handle the application and inspections as part of the job.

What is the cheapest way to get a good deck?

Keep it ground-level, keep it rectangular, skip the cover, and choose a mid-grade composite with a simple railing. You can always add a pergola or upgrade the railing later; what you cannot cheaply change later is the framing, so we never cut corners there.

How accurate is an online estimate?

Ranges like these are a starting point. The only accurate number is an itemized quote after we see the site, because grade, access, soil, and what the deck attaches to all move the price. Our on-site consultation and itemized quote are free.
