Deck Repair or Full Rebuild?

Deck Repair or Full Rebuild

Surface boards lie: a deck can look tired on top and be structurally fine underneath, or look decent and be rotting at the ledger — the connection that causes deck collapses. The repair-versus-rebuild call lives under the deck, at the ledger and posts, not on the walking surface.

What we saw
  • Ledger attachment is the failure mode that matters for safety
  • Board-level wear is cosmetic and repairable at a fraction of rebuild cost
  • Vermont freeze-thaw punishes posts at grade first
Typical cost: $15,000–$40,000

Next step: Probe the ledger board and post bases with a screwdriver — soft wood there changes everything.

Questions people ask

How do I know if my deck needs to be rebuilt or just repaired?

Check where it matters: the ledger (where the deck bolts to the house), the post bases, and the joist ends. If a screwdriver sinks into any of those, you are in structural territory and a professional look is warranted. Grayed or splintered surface boards alone are a repair, not a rebuild.
