Signs It May Be Time to Replace Your Deck

Older decks in King County often experience:

• Soft or rotting structural framing

• Rot around ledger connections

• Aging pressure-treated decking

• Unsafe stairs

• Worn railings

• Decks built under outdated building standards

Not every deck needs a complete replacement. We begin every project with a structural inspection of the framing, footings, ledger connection, and support system to determine whether resurfacing or a full structural deck replacement is the safest and most cost-effective long-term solution.
