Deck Repair

Deck Repair in Seattle, WA | Mill Decking

Not every deck problem requires a full rebuild. Targeted structural repair can extend your deck's life by a decade or more at a fraction of replacement cost. We inspect, diagnose, and fix the actual issue. Rotted joists, failing post connections, damaged ledger boards, storm damage, soft boards, and compromised railings. If the frame is worth saving, we save it. If it's not, we tell you honestly.

FAQs

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

We inspect the substructure and give you a straight answer. If the frame is sound and the damage is contained, repair saves you thousands. If the rot has spread through the framing, replacement is the honest recommendation.

Can you match my existing deck boards?

In most cases, yes. We carry a full material lineup and can match composite, cedar, and pressure-treated boards to your existing surface.

How long does a deck repair take?

Most targeted repairs complete in 1 to 3 days. Larger structural repairs may take longer depending on scope.

Do deck repairs need permits?

Board-only replacements typically do not. Structural repairs involving joists, posts, or ledger boards usually require a permit. We handle the permit process when applicable.
