Building a Custom Deck for Cherry Point's Open Coastal Exposure
Cherry Point sits along the Strait of Georgia in the rural stretch of Whatcom County south of Blaine, and it's a different kind of setting than most of the deck jobs we do closer to town. Lots out here tend to run larger, homes are often set back from the road on acreage rather than packed into a subdivision, and there's frequently open farmland, pasture, or bluff-top exposure around the house instead of neighboring rooflines and mature street trees. That openness is part of what draws people to live here, but it also means a deck built for Cherry Point takes a more direct hit from salt air, driving rain, and wind than a comparable deck a few miles inland or tucked into a sheltered in-town lot.
A custom deck done right for this area accounts for that exposure from the design stage forward — not just in the decking material on top, but in how the structure is framed, fastened, and oriented to the weather this specific stretch of coastline actually sees. This page covers what a Cherry Point deck needs, what a correct build looks like, and how our process works for a custom deck project out here.

What This Stretch of Coastline Does to a Deck
Salt Air With Little to Slow It Down
Homes along the Strait of Georgia at Cherry Point sit close enough to the water that salt-laden air is a constant, and on open rural lots there's often little in the way of windbreak — no dense stand of trees, no row of neighboring houses — to slow it down before it reaches the house. Salt accelerates corrosion in exposed metal: fasteners, brackets, post hardware, and railing connectors all wear faster here than they would on a more sheltered lot. A corroding fastener loses holding strength well before it looks obviously bad, which matters on a structure people stand and walk on every day.
Driving Rain Across Open Ground
Storms coming off the Strait don't just drop rain straight down — wind pushes it sideways across open fields and bluffs with real force, and it arrives at a house with less to break its momentum than it would in a more built-up or tree-covered area. That wind-driven rain gets forced up under railings, into ledger connections at the house, and between deck boards that aren't gapped correctly. A deck surface that would shed water fine on a calm day can still trap moisture the moment wind gets involved, and out here that's most of the time during the wet season.
A Moss Season That Runs Most of the Year
Mild temperatures and near-constant moisture give moss a long growing season across this part of Whatcom County, and horizontal deck surfaces are usually among the first places it takes hold — they hold water longer than a wall and stay damp between rain events. On rural Cherry Point properties with mature landscaping, hedgerows, or shaded north-facing exposures, that moss pressure can run even longer than it does on an open, sun-exposed in-town lot.
Rural, Open-Lot Decks Are a Different Build Than a Town Lot Deck
Less Windbreak Than In-Town Blaine
A deck built a few miles away on a tighter in-town lot in Blaine often has some natural shelter from neighboring structures, fences, or established street trees. Cherry Point properties frequently don't have that buffer, especially on bluff-top or open-field lots. That changes practical decisions like railing style — an open picket or cable railing that looks great and holds up fine on a sheltered lot may need a partial wind screen or a sturdier attachment method on a wide-open Cherry Point site to perform the same way over time.
Bigger Lots Often Mean Bigger Decks
Rural acreage tends to invite larger deck footprints than a compact in-town lot allows — wraparound designs, multi-level layouts following a sloped or bluff site, or decks sized for entertaining rather than a small patio-replacement footprint. Larger structures carry more structural considerations: longer spans, more support posts, and more total linear footage of railing and fastener connections exposed to the same salt air and wind load. A bigger deck isn't just a scaled-up version of a small one — the framing and support layout has to be engineered for the actual size and site conditions, not adapted from a smaller stock design.
Choosing the Right Decking Material for Cherry Point
Material choice matters more out here than it does on a sheltered lot, because the gap in performance between a well-suited product and a poorly-suited one shows up faster under sustained salt air and open wind exposure. The three main categories homeowners weigh are pressure-treated or cedar wood, capped composite, and cellular PVC.
| Material | Handling Salt Air & Wind-Driven Rain | Moss Resistance | Upkeep |
|---|---|---|---|
| Cellular PVC | Excellent — no wood fiber to absorb moisture | Strong, smooth non-porous surface | Occasional washing |
| Capped composite | Strong — cap layer resists moisture and staining | Good on most product lines | Occasional washing |
| Uncapped composite | Moderate — some moisture absorption at exposed fiber | Fair; more prone to buildup over time | Periodic cleaning |
| Cedar | Moderate — natural resistance, but needs sealing | Fair when sealed and maintained | Regular oiling or sealing |
| Pressure-treated wood | Weak against sustained salt exposure over time | Poor without regular treatment | Regular sealing or staining |
On a more sheltered lot, a homeowner has a bit more room to choose wood and stay on top of maintenance without much penalty. On an open Cherry Point site with steady salt air and wind, that maintenance gap widens fast, which is why we spend real time walking through these trade-offs rather than just quoting a material by default.
What a Correctly Built Deck Involves on an Exposed Rural Lot
The decking surface gets most of the attention when homeowners picture a new deck, but on a Cherry Point property, the framing, fasteners, and drainage details underneath are what actually determine how long it lasts. A build done right out here includes:
- Framing material rated for sustained moisture exposure, sized correctly for the span and load rather than a generic stock layout
- Stainless steel or coastal-grade corrosion-resistant fasteners throughout, not standard hardware that starts corroding in open salt air within a few seasons
- Hidden fastener systems on the walking surface where the product allows, reducing exposed metal and giving a cleaner finish
- Correct board gapping for drainage and material movement, so wind-driven rain can actually shed and dry between boards instead of sitting
- Proper ledger board flashing at the house connection, since that's one of the most common places moisture gets into a poorly built deck
- Post footings and support layout sized for the actual span on larger rural decks, not just the minimum code spacing
- Railing and post attachment sized for real wind exposure, especially on open bluff-top or field-facing sites with no windbreak
- Grading and ventilation underneath the deck so moisture doesn't sit against the framing between storms
Skip any one of those and the deck usually still looks fine the first year. The problems show up a few winters later — a soft joist, a loosening railing post, or fastener corrosion staining the boards around it.
Design Considerations for Cherry Point Properties
Open rural lots raise a few site-specific design questions before anything gets built. Wind exposure affects how open a railing design can realistically be versus how much value a partial wind screen or glass panel adds on a site with no natural buffer. Elevation and grade matter more here too — bluff-top or sloped sites often need a more deliberate substructure and drainage plan than a flat in-town lot, and stair placement or multi-level layouts have to work with the terrain rather than against it. Sun exposure on an open lot tends to run stronger through most of the day than on a shaded in-town property, which shifts moss-resistance priorities toward UV stability and fade resistance as much as moisture handling. None of these are one-size-fits-all answers, which is a big part of why a custom deck designed around a specific Cherry Point lot performs differently than a stock layout dropped onto any site.
How Our Process Works
We start with a site visit to look at what's actually there — existing structure condition if it's a replacement, grade and drainage around the deck area, how open or sheltered the lot is through the day, and how the site sits relative to the water and prevailing wind. From there we talk through decking material options that fit the budget and how the space will actually get used, whether that's a quiet spot to sit or a larger deck built for a rural property that regularly hosts family and friends.
Permitting for a deck in this part of unincorporated Whatcom County follows standard setback, structural, and elevation requirements, and we handle that as part of the job rather than leaving it for the homeowner to sort out. Once permitted, the build follows the sequence above — substructure and framing first, sized and fastened for the site's actual exposure, then the decking surface, railing, and any stairs or trim work. We finish with a walkthrough covering what the specific material you chose actually needs going forward, which for most modern decking is minimal, but not nothing.
What Your Deck Still Needs From You
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 or wash the deck surface periodically to clear salt residue, pollen, and organic buildup before it works into the surface or cap layer
- Keep gaps between boards clear of leaves, needles, and debris so water and airflow can move through the way the design intends
- Check railing posts and hardware once a year for early corrosion or loosening, especially heading into the wet season
- Trim back overhanging branches or brush that hold moisture against the deck or block sun and airflow across the surface
- Address any soft framing or standing water underneath right away — that's a structural issue, not a cosmetic one, and it doesn't improve with time
Why It Matters That We Already Work Cherry Point
A crew that mostly builds decks on sheltered, in-town lots can still put one together competently, but a Cherry Point job has variables that don't come up as often on a typical Blaine lot — open exposure with little natural windbreak, wind-driven rain that crosses open ground before it hits the house, and larger sites where structural layout has to be engineered for the actual footprint rather than borrowed from a smaller stock design. Working this area regularly means we're not guessing at those requirements on your project. We know which decking materials actually hold up against this stretch of the Strait's combination of salt air, open wind, and a long moss season, and which fastener grades and framing details are worth the extra time rather than an upsell.
That familiarity also shows up in the smaller judgment calls — how to orient a deck for the wind a specific open lot actually sees, or being straightforward about what a deck here realistically needs to last versus what's just an extra line item.
