Why March Point's Location Changes What a Deck Needs to Survive
March Point sits out on the water between Fidalgo Bay and Padilla Bay, which means homes here take a different kind of weathering than a house a few miles inland in Anacortes or elsewhere in Skagit County. Salt-laden air off the bay works on exposed metal year-round, driving rain off the water finds every gap in a poorly flashed ledger board, and the long, wet Pacific Northwest winter feeds a moss and algae season that can run eight months or longer on shaded, north-facing surfaces. A deck built to a generic national spec doesn't account for any of that. A deck built for March Point does.
None of this means a deck here needs to be over-engineered or expensive to compensate. It means the details that don't show up in a sales brochure — fastener grade, flashing method, board spacing, footing depth — need to be right the first time, because redoing them after the fact means tearing into a structure that's already attached to your house.

What's Actually Underneath a Good Deck
The parts of a deck nobody sees are the parts that determine whether it lasts fifteen years or thirty. Three things matter most in this climate:
Ledger Board Flashing
Where a deck attaches to the house is the single most common point of failure we see on decks built without local know-how. If water gets behind the ledger board and into the house framing, you're not looking at a deck repair anymore — you're looking at rot repair on your home's structure. A correct install uses proper flashing (not just caulk) and self-adhering waterproof membrane between the ledger and the house sheathing, with the flashing lapped so water is directed out and away, not trapped against the wall.
Footings Set Below Frost Depth
Footings need to be sized and set to local frost depth and soil conditions, not guessed at. Undersized or shallow footings are the reason some older decks develop a noticeable bounce or start to lean after a few wet winters — the ground around the footing shifts and the post moves with it.
Joist Protection and Airflow
Every joist top should be protected with joist tape before decking goes down, and the substructure needs enough airflow underneath to dry out between rain events. In a spot that gets driving rain off the water and long stretches of overcast, damp weather, a substructure that can't dry out is a substructure that rots from the inside before the surface ever shows a problem.
Picking a Decking Material That Won't Fight the Climate
There's no single "best" decking material — there's the right material for how you'll use the deck, how much maintenance you want to do, and how exposed the site is to sun, shade, and salt air. Here's how the common options actually compare in a March Point setting:
| Material | Moisture & Moss Resistance | Maintenance | Typical Lifespan |
|---|---|---|---|
| Pressure-treated wood | Fair — needs sealing to shed water and resist moss in shaded areas | Annual cleaning and re-sealing recommended | 10–15 years with upkeep |
| Cedar | Good natural rot resistance, but greys and can host algae if left unsealed | Periodic sealing or staining to keep color and moisture resistance | 15–20 years with upkeep |
| Composite decking | Very good — dense, low-absorption boards resist moisture and moss buildup | Occasional washing; no sealing or staining | 25–30 years |
| PVC/capped decking | Excellent — fully sealed surface, minimal water uptake | Low; periodic washing | 25–30+ years |
In a marine climate with a long wet season, we generally steer homeowners toward composite or capped PVC decking for anything low to the ground or shaded by trees, simply because those boards don't give moss and algae the porous surface they need to take hold. That said, plenty of March Point homeowners want the look and feel of real wood, and a properly sealed and maintained cedar or treated deck holds up fine here — it just asks more of you as the owner. We'll walk you through the honest trade-offs for your specific site rather than push whatever's easiest for us to install.
Hardware and Fasteners: Small Parts, Big Consequences
Salt air corrodes ordinary hardware faster than most homeowners expect, and a deck is only as good as the fasteners holding it together. We use stainless steel or coated structural fasteners rated for exterior and coastal-adjacent use, not standard galvanized deck screws that can start showing rust streaks within a couple of years in this kind of air. We also pay attention to galvanic corrosion — mixing incompatible metals (say, an aluminum flashing detail against the wrong grade of steel fastener) can cause accelerated corrosion right at the connection point, which is exactly where you don't want a weak spot.
This is a place where cutting a corner doesn't show up for a year or two, and by the time it does, the fix means pulling boards and replacing fasteners throughout the structure. It's cheaper to spec it correctly the first time.
Designing for Wind, Rain, and View
A lot of March Point lots have real exposure to wind and water views, and both of those factor into deck design in ways an inland lot doesn't have to consider.
Board Spacing and Drainage
Proper gapping between boards lets water shed through instead of pooling on the surface, which matters more here given how often the deck surface stays wet. On decks built over living space or a patio below, we'll also talk through under-deck drainage systems that carry water off the structure entirely instead of letting it drip through onto whatever's underneath.
Railings
Wind off the water is a real factor in railing choice. A fully open rail lets more wind straight across the deck; horizontal cable or partial glass panel rails can cut wind exposure while keeping the view, but they come with their own maintenance and cost considerations we'll go over during design.
Elevation and Site Grading
Sloped lots common around the bay often call for an elevated deck, which changes the structural engineering — taller posts, additional bracing, and stair design all need to account for wind load, not just weight load. We size these to code, not to a guess.
Permits and Code Requirements in the Anacortes Area
Most decks attached to a house, and many freestanding decks above a certain height, require a building permit in Skagit County and within Anacortes city limits. Requirements touch on guardrail height, stair geometry, footing depth, and setback from property lines, and they can vary depending on exactly where a property sits and whether it's inside city limits or in unincorporated county land near March Point. Rather than have you sort through that yourself, we handle the permit application and inspection scheduling as part of the project — it's one less thing you have to chase down, and it protects you if you ever sell the house and a buyer's inspector asks whether the deck was permitted.
How We Approach a March Point Deck Project
Every project starts with an on-site visit, not a phone estimate. We walk the site to look at sun and shade patterns, wind exposure, drainage, soil, and how the deck will actually get used — entertaining, grilling, a quiet spot with a view, direct access to a hot tub. That site-specific read is what drives material and design recommendations, not a one-size-fits-all package.
From there, the process is straightforward:
- Site visit and design conversation, including material options and a realistic budget range
- Detailed proposal covering scope, materials, and timeline
- Permit application and submission to the local jurisdiction
- Construction, with footings and framing inspected before decking goes down
- Final walkthrough so you know how to care for the specific materials on your deck
Before that first site visit, it helps if you've thought through a few basics:
- Roughly how you want to use the space (dining, lounging, hot tub, grill station)
- Whether you have a material preference (wood look vs. low-maintenance composite/PVC)
- Any known drainage or moisture issues on that side of the house
- Whether the deck needs to tie into existing stairs, patios, or landscaping
- A rough budget range so we can match design ideas to what makes sense financially
Maintaining a Deck in a Marine Climate
Even the right materials and construction still need some seasonal attention in this climate. A short annual routine goes a long way:
- Sweep debris out from between boards where moisture and moss tend to collect
- Wash the deck surface at least once a year to clear algae and organic buildup before it stains or gets slick
- Check the ledger flashing and any visible fasteners for early rust or gaps once a year, ideally before the wet season sets in
- Reseal or restain wood decking on the manufacturer's recommended schedule — don't wait until it looks dry and grey
- Keep nearby gutters and downspouts clear so runoff isn't draining directly onto or under the deck
- Trim back overhanging branches that keep sections of the deck shaded and slow to dry
Why Hire a Crew That Already Works March Point
A deck built to a generic spec sheet can look identical to a deck built for this climate on the day it's finished. The difference shows up two, five, and ten years later — in whether the ledger flashing held, whether the fasteners are still tight and rust-free, whether moss took over the shaded corner. We build decks throughout the Anacortes area and know which details matter on a site exposed to bay wind and salt air versus a sheltered inland lot, because we've seen what holds up here and what doesn't. That's not something a crew unfamiliar with Skagit County's coastal conditions can match on a first project.
