Deck repair

Deck repair and restoration across San Diego County

Most deck failures in San Diego trace back to three spots: a poorly flashed ledger board, rotted posts in contact with soil, and corroded coastal hardware. The crews we match you with diagnose before they quote, so you hear what has actually failed, what can be repaired, and when a full rebuild makes more sense. If the framing is sound, boards and hardware can often be replaced without touching the structure.

Contractor replacing rotted deck joist boards during a repair in San Diego

What's included in deck repair?

Ledger board re-flashing and re-fastening to prevent water intrusion at the house
Rotted joist and beam replacement on a deck-by-deck basis
Post base and footing assessment, repair, or replacement
Corroded hardware and connector replacement with rated coastal equivalents
Board-level decking replacement when framing is structurally sound

When do you need deck repair?

You can feel soft spots or bounce in the decking surface when you walk on it
A post has dark discoloration, visible rot, or moves when you push on it
The ledger board where the deck meets the house shows gaps, staining, or rot
Hardware, joist hangers, or post bases are visibly rusted or pulling loose
You are getting ready to sell and want the deck to pass a home inspection

How do you tell repair from a rebuild?

Start at the ledger, posts, and connectors, not the walking surface. Soft spots, staining on the wall, rusted hangers, and a board that moves at the house are inspection leads. Flashing a ledger is what keeps water out of the rim joist. Covering a soft spot without tracing moisture leaves the same failure in place.

If the ledger, beams, and most joists are sound, repair can keep the frame. If the ledger is gone into the house or posts fail at the base, a rebuild is often the honest number. You should get both scopes. Call (858) 400-4918.

Deck dry rot and ledger-board repair covers the longer walkthrough.

What do homeowners ask about deck repair?

How do I know if my deck needs repair or full replacement?

The crew assesses the framing during the estimate. If the ledger, beams, and more than half the joists are sound, repair makes sense. If the ledger is rotted into the house rim joist or the posts are failing at the base, a rebuild is usually more cost-effective than piece-by-piece replacement. You get both numbers so you can decide.

What is a ledger board and why does it fail?

The ledger board is the horizontal member that attaches the deck frame to the house. When it is not properly flashed, water infiltrates behind it, rots the ledger and the house framing behind it, and eventually allows the deck to pull away from the structure. A failed ledger is the most common cause of deck collapse. The crews we send re-flash and re-fasten ledger boards to current code.

Does deck repair require a permit in San Diego?

Like-for-like board replacement usually does not. Replacing structural members like ledger boards, joists, beams, or posts often does, especially if the repair changes the loading or configuration. The crew checks before quoting and pulls the permit in its own name when the work falls above the repair exemption threshold.

What is involved in replacing a rotted ledger board?

Replacing a rotted ledger board means opening the wall cladding where the deck meets the house, cutting the failed ledger free, checking the house rim joist behind it for rot, installing new flashing, and re-fastening a new ledger to sound framing. The deck usually has to be temporarily supported while that happens. Because a ledger is a structural member, this work often needs a permit, and the crew we match you with pulls it in its own name. Targeted repairs in this range run $500 to $8,000 depending on how far the rot has travelled into the house framing.

How do you flash a ledger board so it does not rot again?

Flashing the ledger is what keeps water from tracking behind the board into the house rim joist. The matched crew opens the cladding, installs continuous flashing that sheds water over the ledger, and re-fastens into sound framing. Covering a soft spot without tracing the moisture path, including gutters, irrigation overspray, and missing flashing, leaves the same failure in place. Our dry-rot guide walks through those checks before anyone prices a board swap.
