Deck Repair in Seattle
Deck repair restores damaged parts of an existing deck — boards, railings, stairs, connectors or framing members — so it is safe and sound without replacing the whole structure.
Local conditions
What's different about deck repair in Seattle
Persistent moisture, moss and shade make rot the most common deck repair in Seattle. Check joist tops, board seams and the ledger, and clean moss and debris so boards can dry. Slippery, algae-covered surfaces are both a maintenance issue and a safety one. Ledger connections deserve special attention, because constant moisture behind a poorly flashed ledger can rot both the deck and the house rim joist. Many older decks also used untreated or lower-grade lumber that does not hold up in this climate.

What do Seattle's housing and climate data mean for this service?
33% of homes in Seattle's covered ZIP codes were built between 1960 and 1999 — roughly 165,949 houses — and decks original to or added onto homes of that age are the most common repair calls. 37% predate 1960, where add-on decks often need their attachment checked.
Moisture drives most repairs: measurable precipitation falls on about 95 days a year near Seattle (about 37.8 inches in total), and rot starts where that water is trapped — board seams, post bases and the ledger.
The best time for a repair inspection in Seattle is spring, after about 25 freezing nights have had a chance to heave footings, split boards and loosen railings — problems are easiest to spot before furniture goes back out.
About 24 freeze-thaw days a year work fasteners loose and open checks in unsealed wood, which is why popped screws and split boards are common spring repair items in Seattle.

FAQs
Deck Repair questions
Can I replace just a few deck boards?
Yes, if the framing beneath is sound. New wood boards may look different from weathered ones until they age; discontinued composite colors can be hard to match exactly.
Why do my deck screws or nails keep popping up?
Wood shrinks and swells with moisture, which works nails loose over time. Replacing them with proper deck screws usually solves it, but check that the joist beneath isn't rotting.
How often should a deck be inspected?
A yearly look — ideally in spring — catches most problems early. Check the ledger, posts, connectors, railings and stairs as well as the boards.
