Deck cost guides

Every figure in these guides comes from one cost model shared with the deck cost calculator, so the numbers never disagree from page to page. Ranges are published market data with their sources named, not Valley Decks quotes. Each guide also covers the costs a calculator can't see: footings on a slope, permit drawings when a deck sits more than 12 inches above grade in Boise or Nampa, HOA submittals, demolition and access.

• How much does a deck cost in Boise, ID?

  Published 2026 market ranges put a new Boise-area deck at about $25–$40 per square foot installed for pressure-treated pine, $40–$62 for capped composite and $55–$78 for PVC. A 300-square-foot raised composite deck works out near $11,000–$21,000 before railing and stairs. Height, footings, access and permit scope move the final number.

• What does a composite or PVC deck cost in Boise?

  In 2026 market ranges, capped composite decking costs about $40–$62 per square foot installed in the Treasure Valley, so a 300-square-foot raised deck lands near $11,000–$21,000 before railing and stairs. PVC runs $55–$78. The product line, board color, joist spacing, deck height and railing choice decide where your project falls.

• What does a cedar or pressure-treated deck cost in Boise?

  Wood is the lowest-cost way to build a deck in the Treasure Valley. In 2026 market ranges, pressure-treated pine runs about $25–$40 per square foot installed and western red cedar $30–$48. A 300-square-foot raised deck lands near $7,000–$13,500 in treated pine or $8,500–$16,000 in cedar, before railing, stairs and refinishing.

• What does it cost to tear out and replace a deck in Boise?

  Fixr's January 2023 national figures put full deck replacement at $20–$70 per square foot, including $5–$15 per square foot for tear-out and disposal. The new deck itself follows 2026 market ranges of $25–$40 for treated pine to $40–$62 for composite. Keeping a sound frame and resurfacing costs less than a full rebuild.

• What does a covered deck or pergola cost in Boise?

  Fixr's national figures (January 2023) put covered decks at $40–$100 per square foot. In Boise the deck under the cover follows 2026 market ranges of $25–$40 to $55–$78 per square foot by material, and the cover adds posts, footings and a roof frame built for a 25 psf minimum roof snow load. A patio cover needs a Boise building permit.
