Build New or Resurface? Decking Decisions for NJ Backyards

A lot of NJ decks built in the late 90s and 2000s are at the end of their service life. The boards are gray, splintered, and pulling away from the joists — but the framing underneath might still have years left. That's where the build-vs-resurface question starts.

Pop a few boards and look at the joists. If they're solid, square, and properly flashed where the ledger meets the house, you're a candidate for a resurface — new boards and railings over the existing frame. Composite decking (Trex, TimberTech, AZEK) on a sound substructure is the most cost-effective upgrade in the category.

If the joists are spongy, the ledger is rusted, or the posts and footings aren't to current code, build new. Patching over a marginal frame is how you end up replacing the whole deck again in five years — twice the cost, twice the disruption.

Either way, two details matter most: proper ledger flashing where the deck attaches to the house (this is where 90% of deck-related rot starts), and code-compliant railing posts. Both should be non-negotiable on any quote you accept.

Resurfaces typically run 3–5 days. New builds run 1–3 weeks depending on size, footings, and stair complexity.
