Replacing a Deck on March Point's Peninsula
March Point sits out on its own peninsula between Fidalgo Bay and Padilla Bay, just outside Anacortes proper, and that setting is hard on an outdoor deck in a way that's easy to underestimate until you're the one standing on boards that have gone soft. A deck here doesn't get the benefit of a sheltered inland lot or a windbreak of mature trees the way some Anacortes neighborhoods do — it takes weather off open water from more than one direction, which shortens the useful life of a structure that was already built to sit outside year-round with no roof over it.
We do deck work throughout Anacortes and the surrounding Skagit County communities, and March Point is one of the areas where replacing a deck the right way matters more than most, simply because a rebuild done to a generic spec doesn't hold up the way one built for this specific exposure does. This page covers what a March Point deck is actually up against, how to tell when replacement makes more sense than repair, and what a correctly built replacement involves.

What March Point's Water Exposure Does to a Deck
Salt Air From Two Bays
Being surrounded by water on more than one side means March Point properties sit in salt-laden air more consistently than a lot set back from the shoreline. Salt speeds up corrosion in anything metal a deck depends on — fasteners, post brackets, railing hardware, joist hangers — and a corroding fastener loses holding strength well before it looks bad from a distance. On a structure people walk across and lean on, that's a safety issue as much as a cosmetic one.
Wind-Driven Rain
Rain off the water here doesn't fall straight down as often as homeowners might expect; wind pushes it sideways, driving it up under railings, into the ledger connection where the deck ties into the house, and between boards that aren't spaced to shed it properly. A deck surface that would handle calm rain fine can still trap moisture the moment wind gets involved — and on an open peninsula lot, wind is involved more often than not.
A Long Moss Season
Skagit County's mild, damp stretch of the year gives moss a long window to establish, and a horizontal deck surface is one of the first places it takes hold, since it holds water longer than a vertical wall and stays damp between rain events. Shaded sections and north-facing decks are usually first to show it, and any decking material with real surface porosity gives it something to grip onto.
Signs Your Deck Needs Replacement, Not Repair
Not every tired-looking deck needs to come out. But on an exposed lot like March Point, certain signs mean the structure itself is compromised rather than just cosmetically worn, and patching around those problems usually just delays a bigger repair later. Worth checking for:
- Soft, spongy, or spring-feeling boards anywhere on the walking surface, not just at the edges
- Visible rot, splitting, or fastener staining around the ledger board where the deck meets the house
- Railing posts that wiggle or flex at the base — often a sign the post connection or the framing underneath has failed
- Corrosion streaking down from screws, brackets, or joist hangers, especially on the underside of the deck
- Gaps between boards that have closed up or warped unevenly, trapping water instead of shedding it
- A substructure that's more than 15-20 years old, even if the surface boards were replaced more recently
If more than one or two of these show up, a repair is usually just addressing the symptom while the underlying framing keeps deteriorating underneath.
Choosing the Right Decking Material for This Location
Material choice matters more on a peninsula lot than it does further inland, because the performance gap between a well-suited product and a poorly-suited one shows up faster in this much salt air and moisture. The main options homeowners weigh are wood, capped composite, and cellular PVC.
| Material | Handling Salt Air & Moisture | Moss Resistance | Ongoing Upkeep |
|---|---|---|---|
| Cellular PVC | Excellent — no wood fiber to absorb moisture | Strong, smooth non-porous surface | Occasional washing |
| Capped composite | Strong — cap layer resists moisture, staining, and fading | Good on most product lines | Occasional washing |
| Uncapped composite | Moderate — some moisture absorption at exposed fiber | Fair; more prone to surface buildup over time | Periodic cleaning |
| Cedar or pressure-treated wood | Weak to moderate against sustained salt exposure | Fair, and only with regular sealing | Regular oiling or sealing |
Wood can still be the right call for homeowners who want that specific look and are willing to keep up with sealing on a regular schedule. Capped composite is the middle ground most March Point homeowners land on — strong moisture and moss resistance without the maintenance cycle of wood. PVC costs more and can flex a bit more under heavy point loads, but for a deck sitting closest to the water, some homeowners decide the extra moisture resistance is worth it.
What a Correct Deck Replacement Involves Here
The decking surface gets most of the attention when homeowners picture a new deck, but on a site like this, the framing, fasteners, and drainage details underneath are what actually determine how long it lasts. A replacement done right for March Point includes:
- Full removal of the old structure down to the ledger and posts, so any hidden rot or corrosion gets caught before new material goes over it
- Framing material rated for sustained moisture exposure, sized correctly for the span and the loads it needs to carry
- Corrosion-resistant fasteners and hardware throughout — not standard-grade hardware that starts corroding in salt air within a few seasons
- Hidden fastener systems on the walking surface where the decking product supports it, reducing exposed metal on top
- Board spacing set for drainage and material movement, so wind-driven rain can actually get off the surface instead of pooling between boards
- New ledger flashing at the house connection — the single most common spot for water intrusion on a poorly built deck
- Joist spacing matched to the specific decking product's span rating rather than a generic framing layout
- Post and railing attachment sized for open-water wind exposure, not a sheltered-lot assumption
Skip any one of those and the deck can still look fine the day it's finished. The problems tend to surface a few wet seasons later — a soft joist, a loosening post, or corrosion staining bleeding down through the boards around it.
Tear-Out, Permitting, and What to Expect
A full replacement starts with removing the existing deck, which on an older structure often reveals more framing or ledger damage than was visible from the surface — something we'll walk you through before moving forward, not after the fact. Deck work in Anacortes and the surrounding county generally falls under standard building permit requirements tied to structural work, setbacks, and elevation, and we handle that process as part of the job rather than leaving it for the homeowner to sort out. Debris removal and disposal from the old structure is included in the scope, so there's no separate hauling project left on your plate once the tear-out is done.
How Our Process Works
We start with a site visit to look at what's actually there — the condition of the existing deck and ledger connection, drainage and grade underneath, sun and wind exposure through the day, and how directly the site faces open water. From there we talk through decking material options that fit the budget and how the space actually gets used, whether that's a quiet spot to sit or a larger deck built for having people over.
Once the scope and material are settled and permits are in place, the build follows the sequence above: tear-out first, then substructure and framing sized and fastened for the site's real exposure, then the decking surface, railing, and any stairs or trim. We finish with a walkthrough covering exactly what the material you chose needs going forward — for most modern decking that's minimal, but it isn't nothing.
Keeping a New Deck Performing Long-Term
Even a well-built deck in the right material needs some routine attention in this climate to reach its full lifespan. A short list worth keeping in mind:
- Rinse the deck surface periodically to clear salt residue and organic buildup before it works into the surface or cap layer
- Keep the gaps between boards clear of leaves and debris so water and airflow can move through as designed
- Check railing posts and hardware once a year for early corrosion or loosening, especially heading into the wet season
- Address any soft framing or standing water underneath right away — that's a structural issue, not a cosmetic one
Why It Matters That We Already Work March Point
March Point doesn't see the volume of contractor traffic that busier parts of Anacortes and Skagit County do, and that sometimes means homeowners here end up with a crew that's applying a sheltered-lot approach to a site that doesn't have the benefit of shelter. Working this peninsula regularly means we're not guessing at what it needs — we know which decking lines actually hold up against salt air coming off two bays instead of one, and which fastener grades and framing details are worth the extra time rather than an upsell nobody asked for.
That familiarity also shows up in the smaller judgment calls: how to orient a deck for the wind a specific March Point lot actually sees, and being straightforward about what a deck here realistically needs to last versus what's just an extra line item.
