Decking Replacement · San Juan Island, WA · San Juan County

Decking replacement on San Juan Island, WA — new boards on a frame we've verified.

San Juan Island decks split by exposure — west-side view decks take salt spray with wind behind it while valley decks fight moss and shade. We replace the decking and railing on structurally sound frames, and flash the house connection like the wall penetration it is.

RESURFACING

Deck Resurfacing on Your Existing Frame

Here's the honest economics of San Juan Island decks: the boards fail long before the frame does. A strait-facing view deck loses its cedar to salt, sun, and wind; a valley deck loses it to moss and shade — either way the boards go soft in 15–20 years while the pressure-treated joists underneath often have decades left. Resurfacing — new decking and railing on your existing frame — captures that difference, typically saving thousands over a full rebuild.

To be clear about what we do: we replace decking on existing, structurally sound frames — we don't build new decks from the ground up. The frame verdict comes first: we probe joists, posts, and the ledger connection before quoting, and on west-side decks we inspect the connectors and fasteners as hard as the wood, because wind-driven salt kills hardware first. If the structure passes, you get composite-ready spacing corrections and new boards. If it doesn't, we tell you straight.

The detail most island decks get wrong is the ledger — the board bolting the deck to your house. On a bluff deck the strait drives water at that seam all winter, and what gets behind it rots the house wall itself, turning a deck project into a rot restoration. As a siding contractor, we flash that connection to wall standards, not deck-builder shortcuts.

The Frame Check
Joists probed for rot at every bearing point
Posts and footings checked for settlement
Ledger connection inspected from both sides
Joist spacing verified for composite specs
Composite in Moss Country

Capped composite is the default recommendation on both sides of the island — the polymer shell shrugs off valley moss and west-side salt alike, with no stain cycle and no splinters. Cedar stays on the menu for purists who accept the maintenance; we quote both honestly.

FAQ

Decking Questions From San Juan Island Homeowners

Deck size, board choice, and railing drive the number — composite costs more per square foot than cedar but ends the stain cycle. Because we reuse your sound frame, resurfacing typically runs well below a full rebuild. The free assessment gives you a firm, itemized figure.
