That old deck has seen better days. But should you repair it or tear it down?

This is a common question for Boise homeowners. Our climate—hot summers, cold winters, and everything in between—is hard on outdoor structures. Here's how to decide.

Signs Your Deck Just Needs Repair

Minor issues that are fixable:

  • A few loose or warped boards
  • Wobbly railings (often just loose fasteners)
  • Surface staining or discoloration
  • Nail pops
  • Small areas of rot (less than 10% of decking)
  • If the structural components—joists, beams, and posts—are solid, repairs usually make sense. You might spend $500-$2,000 on repairs versus $10,000+ on a new deck.

    The "stomp test": Walk across your deck and stomp a bit. Feel solid? Good sign. Feel bouncy or soft? Could indicate structural issues.

    Signs It's Time for Demolition

    Structural problems that are expensive to fix:

  • Rot in joists or beams (not just decking boards)
  • Posts sinking or leaning
  • Deck pulling away from the house
  • More than 30% of decking is damaged
  • Code violations from original construction
  • Age matters: Most wood decks in Idaho last 15-25 years. If yours is approaching that age and showing significant issues, replacement often makes more financial sense than extensive repairs.

    The ledger board: This is where the deck attaches to your house. If it's rotting or improperly installed, the deck can literally fall off your home. That's a safety emergency.

    The Cost Comparison

      Deck repair costs (typical for Boise):
    • Board replacement: $5-15 per board
    • Railing repair: $100-500
    • Post replacement: $200-400 per post
    • Staining/sealing: $500-1,500
      Complete deck replacement (12x16 standard deck):
    • Demolition and removal: $600-1,200
    • New pressure-treated deck: $8,000-15,000
    • Composite deck: $15,000-25,000

    The break-even point: If repairs would cost more than 50% of replacement, most contractors recommend starting fresh.

    What Deck Demolition Involves

    If you decide to tear it down, here's the process:

    1. Disconnect from house: The ledger board comes off carefully to avoid house damage 2. Remove railings and decking: Board by board 3. Take down framing: Joists, beams, support structure 4. Pull posts: These are usually set in concrete 5. Remove concrete footings: Sometimes left in place if below grade 6. Haul away debris: A typical deck fills a truck or dumpster

    Timeline: 1-2 days for most decks.

    DIY warning: Deck demolition looks simple, but it's harder than it appears. Heavy materials, potential for injury, and the disposal challenge make professional removal worth considering.

    After Demolition: What's Next?

    If you're rebuilding: Have your contractor review the old deck's footprint. Code requirements may have changed since it was built.

    If you're not rebuilding: We grade the area and can spread grass seed or lay gravel. Some homeowners turn old deck spaces into patios or garden beds.
