Custom Decks Built for Cherry Point's Waterfront Conditions
Cherry Point sits right up against the Strait of Georgia in Whatcom County, and that location shapes every deck we build out here. Homes along this stretch of shoreline and the rural properties set back from it both deal with the same core problem: near-constant exposure to salt-laden marine air, heavy seasonal rain, and long stretches of shade and dampness that feed moss and algae. A deck that would hold up fine in a drier inland neighborhood can start showing corrosion, soft spots, or slick green growth within a couple of seasons out here if it wasn't built with that exposure in mind.
We build custom decks for Cherry Point homeowners the way we'd want one built for our own house in the same conditions — with material choices, fastener selection, and drainage details that are chosen specifically because of where the deck sits, not just because they looked good in a catalog.

What Salt Air, Rain, and Moss Actually Do to a Deck
It helps to understand the specific mechanisms at work, because they're what drive every decision in a good deck design here.
Salt air and corrosion
Airborne salt from the Strait doesn't just affect boats and metal railings near the water — it settles on fasteners, joist hangers, and any exposed hardware, accelerating rust and corrosion far faster than it would happen a few miles inland. Standard hot-dip galvanized hardware can start pitting and staining within a few years in a heavy salt-air environment; the wrong fastener choice is one of the most common reasons we see older decks in this area with rust-streaked boards and loosening connections.
Driving rain and moisture intrusion
Whatcom County's rain doesn't always fall straight down — wind off the water pushes it sideways into ledger connections, under railing posts, and into any gap where flashing was skipped or done poorly. Once moisture gets behind a ledger board or into an unsealed post base, rot can develop out of sight for years before it shows up as a soft spot or a sagging rail.
Moss, algae, and shade
Long wet seasons combined with tree cover or north-facing exposure common on many Cherry Point lots create ideal conditions for moss and algae on deck surfaces. Beyond the cosmetic issue, a mossy deck surface holds moisture against the boards and gets genuinely slippery — a real safety concern on stairs and landings, not just an upkeep annoyance.
Designing a Deck That's Actually Built for This Location
A custom deck here starts with the same questions any good deck project should: how you'll use the space, how it connects to the house, what the site's grade and drainage look like. But in Cherry Point we weight a few things more heavily than we would in a sheltered inland yard.
Footings and framing
Footing depth and spacing need to account for local soil conditions and frost depth, and we size framing so the structure isn't marginal — undersized joists or over-spanned beams age faster under constant damp-dry cycling. We also pay close attention to ledger flashing where the deck attaches to the house, since a poorly flashed ledger is one of the most common sources of hidden rot on any deck, coastal or not.
Drainage and airflow
Standing water and trapped moisture under the deck surface are what feed rot and moss growth. We grade for positive drainage away from the foundation, keep joist bays ventilated, and avoid design choices that create low spots or dead air pockets under the decking.
Hardware and fasteners
This is where we differ most from a generic deck build. In a heavy salt-air zone like Cherry Point, we default to stainless steel or coated fasteners rated for corrosive and coastal environments rather than standard-grade hardware, and we use joist hangers and structural connectors built for the same exposure. It costs a bit more upfront. It's also the difference between hardware that's still solid in fifteen years and hardware that's rust-streaked and loosening in five.
Choosing a Decking Material for Salt Air and Rain
There's no single "best" decking material — it depends on your budget, how much upkeep you want to do, and how close to the water your lot sits. Here's how the common options actually perform in Cherry Point's conditions.
| Material | Upfront Cost | Maintenance | How It Handles This Climate |
|---|---|---|---|
| Pressure-treated wood | Lowest | Annual cleaning, periodic sealing/staining | Affordable and repairable, but needs consistent upkeep to resist moss growth and moisture damage; skipped maintenance shows up fast here |
| Cedar | Moderate | Regular sealing to hold color and resist moisture | Naturally moisture- and insect-resistant and handles our damp climate well, but will gray and needs upkeep to avoid surface moss without treatment |
| Capped composite | Higher | Occasional washing, no staining or sealing | Strong resistance to moisture and mold; a capped surface sheds moss and algae far more easily than wood, good fit for shaded or damp lots |
| PVC decking | Highest | Occasional washing | Fully synthetic, essentially immune to rot and moisture intrusion, very low maintenance — the trade-off is a higher initial cost and a different feel underfoot than wood |
For a lot with heavy shade, standing damp, or direct exposure to marine air, we usually steer clients toward composite or PVC unless they specifically want the look and feel of real wood and are prepared to keep up with sealing. For sunnier, more sheltered lots set back from the water, a well-built and properly maintained wood deck can still be the right call.
Railings and fasteners deserve the same thought
The decking surface gets the most attention, but railings, post bases, and stair stringers see just as much weather. We match railing hardware to the same corrosion standard as the framing, and we avoid mixing metals that can accelerate galvanic corrosion when they're in constant contact with salt-laden moisture.
Our Custom Deck Process
Every project runs through the same sequence, adjusted for your lot and how you want to use the space.
- On-site consultation. We look at your lot's grade, sun and wind exposure, tree cover, and how close you are to open water, since that changes our material and hardware recommendations.
- Design and material selection. We walk through layout, decking material, railing style, and any built-ins like stairs, benches, or privacy screening, with honest trade-offs on cost and maintenance for each option.
- Permitting. Whatcom County requires permits for most new deck construction and many significant deck rebuilds. We handle the permit submission and inspections as part of the project.
- Site prep and footings. Footings are sized and placed for your soil and framing loads, not just to the minimum the plan allows.
- Framing. Ledger attachment, flashing, joists, and beams go in with corrosion-rated hardware throughout.
- Decking, railing, and finish work. Surface material and railings are installed, fastened, and finished to the standard the material calls for.
- Final walkthrough. We go over the finished deck with you, including what maintenance it will and won't need going forward.
Keeping a Cherry Point Deck in Good Shape
Whatever material you choose, a little regular attention goes a long way in this climate. A basic seasonal checklist:
- Sweep debris and standing leaves off the surface regularly, especially under tree cover, so moisture and organic matter don't sit against the boards
- Wash the deck surface at least once or twice a year to remove early moss and algae growth before it takes hold
- Check railing posts, stair connections, and visible fasteners annually for rust, staining, or looseness
- Reseal or restain wood decking on the schedule the product calls for — don't wait until it's visibly gray and dry
- Keep gutters and downspouts near the deck clear so runoff isn't being dumped directly onto or under the structure
- Clear gaps between boards periodically so water and debris can actually drain instead of pooling
Why It Matters to Hire a Crew That Already Works in Cherry Point
A deck built with inland assumptions — standard hardware, a generic drainage plan, a material choice made without accounting for salt air — tends to show its age early out here. Crews who regularly work this stretch of Whatcom County know which fastener grades actually hold up near the water, how local soil and drainage patterns behave, and what the county's permitting and inspection process expects for coastal construction. That local familiarity shows up less in what a deck looks like on install day and more in how it's still performing five and ten years later.
We're not guessing at what Cherry Point's climate does to a structure — we see it on every callback and every older deck we're asked to repair or replace. That experience directly shapes the framing, hardware, and material recommendations we make on new builds.
