If the main support posts, beams, or ledger board (where the deck attaches to your house) are rotted or structurally compromised, replacement is usually safer and more cost-effective than repair. If the damage is limited to surface boards, railings, or fasteners, repair is often enough. A professional inspection can give you a clear answer and help you avoid overspending on either option.

Most standard-sized decks take anywhere from 3-10 days to build, depending on size, materials, and design complexity. Custom features like multi-level decks, built-in seating, or pergolas can extend the timeline. Weather and permit approval can also affect scheduling.

Wood decking is often less expensive upfront and offers a natural look, but requires regular staining, sealing, and maintenance. Composite decking costs more initially but resists rot, warping, and fading, requiring little more than occasional cleaning—making it a popular long-term investment.

In most areas, yes especially for new installations or decks over a certain height or size. Permit requirements vary by city and county, so it's best to check local building codes or let your contractor handle the permitting process for you.

Repair costs vary widely based on the extent of damage, ranging from a few hundred dollars for minor fixes to a few thousand for structural repairs. New deck installations typically range based on size, materials, and design complexity, with composite and multi-level decks costing more than basic wood platforms.
