What's the actual difference between a general contractor building a deck and a crew that specializes in decks?

Deck-specific experience means more familiarity with framing spans, ledger flashing, and drainage details that don't come up as often in general carpentry or remodeling work. It's not that a general contractor can't build a sound deck, but a crew that builds them regularly tends to catch marine-exposure details, like fastener grade and airflow, without having to research them mid-project.

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

Ask specifically what fastener and hardware grade they use, since standard exterior-rated screws corrode faster in salt air than marine-grade stainless options. Also ask how they flash the ledger board connection to the house, whether they pull the required permits themselves, and whether they'll put their material and workmanship coverage in writing.

Do you install a specific brand of composite or PVC decking?

We work with several established composite and PVC decking lines rather than pushing one brand for every job, since the right choice depends on your budget, color preference, and how much maintenance you want to take on. We'll go through actual product options and current pricing with you during the estimate.

What's the difference between standard stainless fasteners and marine-grade ones, and does it matter for a deck?

Marine-grade stainless (commonly 316-grade) resists salt-driven corrosion significantly better than lower grades or standard coated deck screws, which matters directly for a site exposed to salt air off the water. Using the wrong grade doesn't usually fail right away — it shows up years later as rust staining and weakened connections, which is harder and more expensive to fix than building it right the first time.

Q: Does building a deck in March Point require any permitting beyond a standard Anacortes building permit?

Most deck projects need a standard building permit, but properties near shoreline or designated critical areas can be subject to additional review depending on setback and site conditions. We check this as part of planning your project and handle the permit process directly so it doesn't become a surprise partway through the job.

Decks Built for March Point's Water-Exposed Climate

March Point sits out on the water, with Fidalgo Bay and Similk Bay wrapping around much of the peninsula. That location is what makes the area beautiful, and it's also what makes deck-building here different from a typical inland Skagit County job. Homes out this way take on more salt-laden air, more wind-driven rain, and a longer moss season than a lot of Anacortes properties set back from the shoreline. A deck built to a generic spec sheet doesn't hold up the same way out here — the fasteners corrode faster, the boards stay damp longer, and moss and algae get a head start in the shaded, humid pockets under railings and along the house line.

None of that means a deck can't be done right in March Point. It means the material choices, the hardware, and the framing details all need to account for salt exposure and near-constant moisture instead of treating this like a dry-climate build. That's the difference between a deck that looks good for two summers and one that's still solid in fifteen years.

What Salt Air and Driving Rain Actually Do to a Deck

It helps to understand the specific ways coastal exposure wears a deck down, because it changes what "good enough" materials actually means out here.

Salt Air and Metal Hardware

Salt in the air accelerates corrosion on anything metal — screws, joist hangers, bolts, and post bases. Standard coated deck screws that would last decades in a dry inland yard can start rusting and staining the decking within a few seasons this close to the water. Once a fastener starts to corrode, it weakens the connection it's holding and often leaves a rust streak bleeding into the wood or composite around it.

Driving Rain and Wind-Blown Moisture

Rain around Anacortes doesn't always fall straight down. Wind off the water pushes it sideways, which means it gets up under railings, into ledger connections, and behind any trim that isn't properly flashed. A deck detail that would shed water fine in a calmer inland spot can let water track back into the structure here if it wasn't built with that wind-driven moisture in mind.

Moss, Algae, and Shade

Long gray winters plus a lot of moisture-holding surfaces add up to a real moss and algae season on decks in this area — not just on roofs. Board surfaces, stair treads, and anywhere water sits or shade lingers can turn slick and green if the deck wasn't designed with drainage and airflow in mind from the start.

Decking Material: What Holds Up Out Here

There's no single "right" decking material for every homeowner — budget, look, and maintenance tolerance all factor in. But some materials handle March Point's conditions with a lot less trouble than others, and it's worth understanding the trade-offs before you decide.

Material	Salt Air / Moisture Behavior	Moss & Algae Resistance	Maintenance
Pressure-treated wood	Prone to cupping, splitting, and fastener staining if not sealed regularly	Needs regular cleaning; grain holds moisture	Annual cleaning and re-sealing recommended
Cedar	Naturally decay-resistant but still needs sealing near saltwater	Better than treated pine but still needs upkeep	Sealing every 1-2 years
Capped composite	Doesn't absorb moisture or salt; won't rot	Some surface texturing helps; still needs occasional washing	Occasional cleaning, no sealing or staining
PVC decking	Fully moisture-proof, handles salt exposure very well	Smooth, hard surface resists buildup better than wood	Low — periodic washing only

Composite and PVC decking cost more up front than treated lumber, but on a water-exposed site like March Point, the lifetime cost gap narrows fast once you account for repeated sealing, board replacement, and the labor of keeping wood clean of moss year after year. We'll walk through actual product lines and pricing for your project during an estimate rather than push one material for every job — the right call depends on your budget, your home's style, and how much upkeep you want to sign up for.

Framing and Hardware: The Part You Don't See

A deck's surface material gets all the attention, but the framing underneath is what actually determines how long it lasts in a marine environment. This is where corners get cut on a lot of builds, and it's not visible until something fails.

Fastener grade matters. In salt-exposed locations we use corrosion-resistant fasteners rated for the exposure — this is a detail worth asking any contractor about directly, because standard exterior-rated hardware is not the same as marine-grade.
Ledger board flashing. Where the deck attaches to the house is the single most common point of hidden water damage. Proper flashing keeps wind-driven rain from tracking behind the ledger and into the rim joist or wall framing.
Joist protection. Capping or wrapping joists reduces how much moisture the framing lumber absorbs over time, which matters more here than in a drier inland yard.
Post bases off the ground. Keeping structural posts off direct soil or standing water contact reduces rot risk and keeps hardware away from ground-level moisture.
Airflow underneath. A deck built tight to the ground with no ventilation traps moisture and speeds up both wood decay and moss growth. Proper height and gapping let air move through.

Design Choices That Cut Down on Moss and Maintenance

A lot of the moss and mildew that shows up on decks isn't inevitable — it's often a byproduct of design decisions that didn't account for drainage and airflow. A few things we build in from the start:

Board Spacing and Drainage

Proper gapping between boards lets water pass through instead of pooling, which matters a lot more here than in drier parts of the state. Standing water is what gives moss and algae a foothold, so getting the drainage right at the framing stage saves years of scrubbing later.

Under-Deck Drainage Systems

For decks with usable space underneath — a patio, storage, or a lower-level entry — an under-deck drainage system channels water off the top surface and away from that space below, instead of letting it drip through indefinitely.

Railing and Post Details

Shaded, low-airflow spots around railing posts and stair stringers are classic moss magnets. Detailing those connections so they shed water instead of trapping it against the framing reduces both moss and long-term rot risk in those spots.

Our Process for a March Point Deck

Every deck project starts with understanding your specific site — sun exposure, wind direction off the water, existing drainage, and how the deck will actually be used — before any material decisions get made.

Site walk and assessment. We look at exposure, existing structure (if this is a rebuild), grade, and drainage patterns specific to your property.
Design and material conversation. We talk through decking material, railing style, and layout against your budget and how much maintenance you want to take on.
Permitting. We handle the permit process through the applicable local jurisdiction, including any additional review that can apply to waterfront-adjacent properties.
Demolition (if applicable) and framing. Old decking and any compromised framing come out; new framing goes in with corrosion-resistant hardware and proper flashing at the house connection.
Decking, railing, and finish work. Boards, railings, stairs, and trim get installed to the spec we agreed on, with attention to the drainage and airflow details covered above.
Final walkthrough. We go over the finished deck with you, including basic maintenance guidance specific to the material you chose.

Permits and Local Considerations

Deck projects in Anacortes and unincorporated Skagit County generally require a building permit, and properties near shoreline or critical areas can have additional review depending on setback and site conditions. We handle that process as part of the job rather than leaving it for the homeowner to sort out, and we'll flag early on if your specific lot is likely to need extra review so there are no surprises mid-project.

Why It Matters That We're a Local Crew

A contractor who mostly works drier, inland sites can still build a structurally sound deck — but they may not default to marine-grade hardware, proper ledger flashing for wind-driven rain, or drainage details that account for a moss season that runs longer than it does a few miles inland. Working regularly in Anacortes and around the water means those details aren't an afterthought; they're just how the job gets built. We also know which permitting questions tend to come up for waterfront-adjacent lots in this area, which keeps the process moving instead of stalling on paperwork we've never dealt with before.

Deck Planning Checklist for March Point Homeowners

If you're weighing a new deck or a rebuild of an aging one, these are the questions worth having answered before work starts:

Is the current framing or ledger connection showing rot, rust staining, or soft spots?
What fastener grade and hardware will be used, and is it rated for salt-air exposure?
How will the ledger board be flashed against wind-driven rain?
Does the layout allow airflow underneath and proper board drainage, or will water pool anywhere?
Which decking material fits your maintenance tolerance — annual sealing, or mostly hands-off?
Does the site need shoreline or critical-area permit review in addition to a standard building permit?
What's the realistic timeline given permitting and weather windows in your part of the build season?

Salt air, wind-driven rain, and a long moss season aren't reasons to avoid building a deck in March Point — they're just conditions that need to be planned for.
