Deck Ledger Repair and Replacement
The ledger is the board that ties your deck to the house, and it is the most common place decks fail. If it was never flashed, water has been rotting it and the rim joist behind it for years. We shore the deck, replace the ledger, flash it properly and bolt it back on.

How we approach deck ledger repair
A deck can look fine from above while the ledger is failing. Water runs down the siding, gets behind the ledger board and sits there. Over the years the ledger, the house rim joist and the sheathing around it rot, and the nails or lag screws holding the deck lose their grip. Collapses almost always start here.
We support the deck with temporary posts, remove the boards near the house, take off the old ledger and open the siding. Rotted rim joist and sheathing get replaced, then the new ledger goes on over proper flashing, through-bolted or attached with structural screws, with lateral load connectors where the code calls for them. Joist hangers are replaced at the same time.
Ledger work is often done together with new decking, since the boards near the house come up anyway. If the rest of your frame is sound, we will tell you, and you will not pay for a new deck you do not need.
