Does Your Deck Need Repair or Full Replacement?
When Deck Repair Still Makes Sense
Repair is right when damage is isolated and the framing is sound. Replacing a few split boards, fixing a railing post, resealing a cedar deck — these are legitimate repairs that extend useful life by five to ten years. The practical rule: if repair cost is less than 50 percent of replacement cost and the framing has no structural concerns, repair is worth doing.
Signs the Structure Is No Longer Safe
Before calling a contractor, do a simple inspection around the post bases, ledger board, and joist ends. If the wood feels soft, crumbles easily, or allows a screwdriver to sink in without much pressure, the framing may already have structural rot.
