What affects the cost of deck structural repair?
Extent of rot
One sistered joist is limited work; widespread rot at the beam, posts or ledger is a much larger rebuild.
Access under the deck
A high deck can be worked from below, while a low deck often means removing decking to reach the framing.
Connections and hardware
Post bases, joist hangers and the ledger connection are where decks fail, and correcting them takes proper hardware and fasteners.
