Decks — Composite and Cedar Decks2026-09-11T11:38:59-07:00

Decks built for how the PNW actually weathers

Cedar, composite, and covered decks across Bellingham and Whatcom County. Framed for the long term, finished for the way you actually live outside.

A well-built deck lasts twenty-plus years. Most don't

Most decks in Whatcom County fail early because of two things: undersized structural framing, and moisture getting into fasteners and joints. Both are avoidable, and both come down to how the deck is built underneath the surface you see.

We frame decks with the ledger properly flashed to the house, joists at correct spacing for the decking material, hidden fasteners where the surface supports them, and stainless or coated hardware everywhere metal touches wood.

What's included

Composite

Trex, TimberTech, and similar systems. Low-maintenance for 25-plus years.

Cedar

Local cedar decking that ages beautifully when cared for.

Covered Structures

Roofed patios and covered decks that extend the outdoor season.

What we offer

Composite Decks (Trex, TimberTech)

Composite decking has become the default choice for many Whatcom County homeowners who don’t want to re-stain every couple years. We install Trex, TimberTech, and comparable systems with hidden fasteners on the surface and structural frames rated for the span.

Cedar Decks

Cedar is still the classic Pacific Northwest deck material — warm, local, and beautiful when maintained. We build with clear or tight-knot cedar, stainless fasteners, and proper gapping so the boards can move with our wet-dry cycles.

Deck Railings

Railings can make or break the look of a deck. We install cable rail, powder-coated aluminum, wood-and-metal composite systems, and traditional wood pickets — all to current code for height and infill spacing across Bellingham and Whatcom County.

Deck Repair and Restoration

Not every tired deck needs a full rebuild. We re-deck over sound framing, replace failing ledgers, sister undersized joists, and refresh railings. We’re honest about when a deck is worth restoring and when the framing has to go too.

Covered Decks and Patios

A roof over your deck buys back months of outdoor time in Whatcom County. We build covered structures matched to your home’s rooflines — solid roofs, translucent panels, or open pergolas — with the structural work coordinated into the existing house.

Frequently Asked Questions

What’s a realistic deck budget?2026-09-09T13:23:24-07:00

A quality 300 sq ft cedar deck in Whatcom County typically runs $15k to $25k. Composite with cable rail runs $25k to $45k. Covered structures add on top.

Can you cover an existing deck?2026-09-09T13:23:16-07:00

Often yes, if the framing and footings are sized to carry the added roof load. We evaluate the structure before quoting a cover-only project.

How long does a deck build take?2026-09-09T13:23:09-07:00

A typical 200 to 400 sq ft deck runs 1 to 2 weeks of construction. Larger multi-level decks or covered patios run longer.

Do decks need permits?2026-09-09T13:23:00-07:00

Most freestanding decks over 30 inches high or decks attached to the house require permits in Whatcom County and Bellingham. We pull permits and coordinate inspections.

Cedar or composite?2026-09-09T13:22:52-07:00

Both are fine choices. Cedar is beautiful and less expensive up front but needs re-staining every 2 to 3 years. Composite costs more but is essentially maintenance-free for 20-plus years. Depends on how you weigh cost vs. maintenance.
