Deck Repair in Salt Lake City, Utah

Deck repair costs in Salt Lake City typically range from $300–$800 for minor repairs (a few boards or a railing section), $800–$2,500 for moderate repairs (multiple boards, joists, or railings), and $2,500–$7,000+ for major structural repairs (ledger board, posts, or extensive rot). Get free quotes from local contractors to get an accurate estimate for your specific situation.

Repair is usually the right call if damage is isolated to less than 30% of the deck surface, the frame and joists are solid, and posts/footings have no rot or heaving. Replacement is typically better if more than half the boards are damaged, the frame has widespread rot, or the deck is over 20 years old with deferred maintenance. A licensed contractor can assess and give you an honest recommendation.

Minor cosmetic repairs (replacing a few boards, painting) generally don't require permits in Salt Lake City. However, structural repairs — including replacing joists, ledger boards, posts, or footings — typically require a building permit and inspection. Railing replacements may also require a permit to verify code compliance. Licensed contractors handle the permit process as part of the job.

Salt Lake City building code requires railings on decks 30 inches or higher above grade. Railings must be at least 36 inches tall for decks up to 6 feet high, and 42 inches tall for decks over 6 feet. Balusters must be spaced no more than 4 inches apart. Railings must withstand a 200-pound lateral load. Licensed contractors ensure all railing repairs and replacements meet current code.

Minor repairs (board replacement, railing fixes) typically take 1–2 days. Moderate repairs involving multiple areas may take 2–4 days. Major structural repairs can take 1–2 weeks depending on scope and permit timelines. Most licensed contractors in Salt Lake City can start within 1–2 weeks of estimate approval.

Salt Lake City's climate is particularly hard on decks. The freeze-thaw cycle — where moisture in wood freezes, expands, and causes cracking — is the primary culprit. UV intensity at elevation (Salt Lake sits at 4,226 feet) degrades finishes faster than at sea level. Heavy snow loads stress structural connections. And summer heat causes wood expansion and finish peeling. Annual inspection and maintenance every 2–3 years significantly extends deck life.

Yes — composite decks can be repaired. Individual composite boards can be replaced if matching material is available. Structural components (joists, posts, ledger board) are typically wood regardless of the decking surface and can be repaired or replaced. Some older composite products may be discontinued, but contractors can often source compatible alternatives or use a complementary accent board pattern.

Verify the contractor holds a valid Utah contractor's license (check at dopl.utah.gov), carries general liability insurance and workers' compensation, provides a written estimate with itemized scope, pulls any required permits, and has local references or verifiable reviews. Avoid anyone who requires full payment upfront or pressures you to sign immediately.
