How long does a typical deck building project take from design to finished construction?

Most residential decks take a few weeks from the start of framing to final finish work, though the permitting process before construction can add several more weeks depending on the local review timeline. Weather and material availability can shift the schedule, especially during the wetter months. We'll give you a realistic timeframe once we've scoped your specific project.

What should I ask a contractor before hiring them to build a deck near the water?

Ask whether they use corrosion-rated fasteners and hardware for coastal exposure, how they detail ledger flashing where the deck meets the house, and whether they pull permits and coordinate inspections as part of the job. Also ask to see how they've handled soil and footing conditions on other builds in the area. A contractor who can answer these specifically, rather than generically, is a good sign.

Is composite decking or natural wood the better choice for a shaded, damp lot?

Composite decking generally resists moisture and moss better than wood on shaded, damp lots because it doesn't absorb water the way wood fibers do, though textured or grooved boards can still hold moss in deep shade if they're not cleaned periodically. Wood costs less upfront but needs more regular sealing and cleaning to perform well in the same conditions. The right answer depends on how much upkeep you want to take on.

What's the difference between hot-dip galvanized and stainless steel deck hardware?

Hot-dip galvanized hardware has a thick zinc coating that resists corrosion well and costs less than stainless steel, making it a solid choice for most deck framing. Stainless steel resists corrosion even further and is often used for the most exposed connections, like ledger bolts, on decks in heavy salt air locations. We match the hardware grade to how exposed each part of the deck actually is.

Does Anacortes require a permit for a new deck, and does that depend on the deck's height?

Most new decks in Anacortes and Skagit County require a building permit, and requirements like guardrails and footing depth can vary based on the deck's height and how it attaches to the house. Permit specifics change over time, so we confirm current requirements with the local building department before finalizing any design. We handle the permit application and inspection coordination as part of the project.

Expert Deck Building for Ship Harbor Homes

Decks Built for Ship Harbor's Marine Climate

Ship Harbor sits on Fidalgo Island's western shoreline, close to the Washington State Ferry terminal and exposed to wind and salt spray off Rosario Strait. That location is part of what makes the neighborhood special — and part of what makes an outdoor deck harder on materials than it would be twenty miles inland. Salt-laden air corrodes fasteners and hardware faster than most homeowners expect, driving rain off the water finds every gap in a ledger flashing detail, and the shade and moisture that come with our Skagit County winters keep deck surfaces damp long enough for moss and algae to take hold. A deck built here needs to be specified for this exposure from the start, not treated like a generic backyard project.

This page focuses specifically on deck building for homes in and around Ship Harbor — material choices, structural details, and maintenance realities that matter more here than they would in a drier, more sheltered part of the county.

What Salt Air and Driving Rain Actually Do to a Deck

It helps to understand the specific failure points before talking about how to avoid them.

Corrosion

Standard electro-galvanized screws, nails, and joist hangers hold up fine in a lot of inland climates. Near the water, that thin zinc coating breaks down faster, and once it does, rust spreads into the wood fibers around the fastener and weakens the connection. This shows up first at joist hangers, ledger bolts, and any hardware that stays wet longer than it can dry.

Moisture intrusion

Wind-driven rain off the water doesn't fall straight down — it gets pushed sideways into ledger boards, stair stringers, and any spot where the deck meets the house. A flashing detail that would be adequate in a calmer microclimate can still let water track behind it here, and that's where rot starts, usually hidden until a board or ledger connection has already been compromised.

Moss and biological growth

Long, wet winters and shaded lots mean deck surfaces can stay damp for days at a stretch. Moss, algae, and mildew don't just look bad — they hold moisture against the decking surface and make boards slippery, which is a real safety issue on stairs and landings.

Choosing the Right Decking Material for This Location

There's no single "best" decking material for every home — it depends on budget, how much maintenance you want to do, and how exposed the deck is. Here's how the common options actually perform in a Ship Harbor-type marine environment.

Material	Moisture & Salt Air Behavior	Moss/Algae Resistance	Maintenance	Relative Cost
Pressure-treated fir/hem-fir	Treated for rot resistance but fasteners and hardware still need to be corrosion-rated	Low — needs regular cleaning and sealing	Annual cleaning, periodic sealing	Lowest upfront
Western red cedar	Naturally rot- and insect-resistant; still needs sealing to hold its color and shed water	Moderate — better than untreated fir, still needs upkeep	Sealing every 1-2 years	Mid-range
Composite decking	Doesn't absorb water or rot; performs well in salt air	Better than wood, but grooved/textured boards can still hold moss in deep shade	Periodic washing, no sealing	Higher upfront, lower long-term
Tropical hardwoods (ipe, cumaru)	Very dense, excellent moisture resistance	Good, but surface can still get slick when wet	Occasional oiling to maintain color	Highest

We don't push one product on every job. A shaded, close-to-the-water lot in Ship Harbor is a different conversation than a sunny, open one a few blocks inland, and we'll walk through the real trade-offs — not just the sales pitch — before you commit to a material.

Framing and Fasteners That Actually Hold Up

The decking surface is the part homeowners see, but the framing underneath is what determines how long the deck lasts. For a marine-exposed build, we treat a few details as non-negotiable:

Stainless steel or heavy hot-dip galvanized fasteners and joist hangers rated for coastal exposure, not standard electro-galvanized hardware
Self-adhered flashing tape on top of every joist before decking goes down, so water that gets between boards can't sit directly on bare framing
Proper ledger board flashing where the deck attaches to the house, including step flashing integrated with the existing siding — not just caulk over a butt joint
Structural screws or through-bolts at the ledger connection rather than nails alone, since this connection carries real structural load
Air gaps and drainage paths at the ledger so moisture doesn't get trapped between the deck framing and the house wall

None of this is visible once the deck is finished, which is exactly why it matters to hire a crew that does it right the first time rather than cutting corners on hardware that "should be fine."

Footings and Drainage on Fidalgo Island Soil

Soil conditions vary block to block on Fidalgo Island, but a common thread near the water is a mix of glacial till, sand, and clay that can drain unevenly. Footings that sit in a low spot or a pocket of poorly draining soil are prone to frost heave and settling over time, which shows up years later as a deck that's started to rock or pull away from the house. We dig footings to the depth required by code for this area, and we pay attention to how water moves across the lot before we decide where posts land — not just where the design drawing puts them. Good drainage away from the footings and the base of the house is as much a part of a correctly built deck as the decking itself.

Permits, Code, and Guardrail Requirements

Most deck projects in Anacortes and unincorporated Skagit County require a building permit, and the requirements aren't just paperwork — they cover things that genuinely matter for safety and longevity:

Joist size and spacing based on span tables for the decking material and expected load
Guardrail height and baluster spacing for any deck above the code threshold height
Stair rise, run, and handrail requirements
Ledger attachment method, especially for decks attached to existing structures
Footing depth and size for the local soil and frost conditions

We handle the permit process as part of the job — pulling permits, building to the approved plan, and getting the final inspection signed off. Skipping that step might save a little time upfront, but it leaves you with a deck that can complicate a future home sale or insurance claim if something goes wrong.

Our Deck Building Process

Every deck we build goes through the same basic sequence, adjusted for the specific home and site:

On-site consultation. We look at the lot, sun and shade patterns, drainage, and how the deck will connect to the house before talking materials.
Design and material selection. We walk through the real trade-offs between decking materials for your budget and exposure, not just a catalog pitch.
Permitting. We prepare and submit the permit package and build to the approved plan.
Site prep and footings. Excavation, footing placement, and structural post setting, checked against the soil conditions on your lot.
Framing. Joists, ledger attachment, flashing, and hardware installed to marine-exposure standards.
Decking, railing, and finish work. Surface installation, guardrails, stairs, and any trim or skirting.
Final walkthrough and inspection. We review the completed deck with you and coordinate the final building inspection.

Living With Your New Deck: Moss and Seasonal Maintenance

No deck in this climate is maintenance-free, but a well-built one is manageable. A basic seasonal routine goes a long way:

Sweep debris off the deck regularly, especially in fall when leaves and needles trap moisture against the surface
Clean moss and algae with a deck-safe cleaner before it builds up — pressure washing alone can damage wood fibers and composite surfaces if done incorrectly
Check and clear drainage gaps between boards so water isn't pooling
Reseal wood decking on the schedule appropriate to the species (typically every one to two years)
Inspect railings, stair connections, and ledger flashing once a year for any signs of movement or water staining
Keep gutters and downspouts near the deck clear so roof runoff isn't dumping extra water onto the structure

We're happy to walk any homeowner through a maintenance schedule specific to the material we install, so the deck actually gets the lifespan it's built for.

Why Hire a Crew That Already Works Ship Harbor

A lot of deck problems we get called to fix didn't come from bad workmanship in the obvious sense — they came from a design that would've been fine in a drier, more sheltered part of the state but wasn't specified for salt air and driving rain off the water. Fastener grade, flashing details, and material choice all need to account for this specific exposure, and that only happens reliably when the crew building your deck already understands what Ship Harbor's climate does to a structure over time. We build decks across Anacortes and the rest of Skagit County, and we bring the same attention to marine-grade hardware and drainage detailing to every project near the water.
