How long does a custom deck build usually take from the first site visit to completion?

A straightforward deck can often be designed, permitted, and built within a few weeks, while larger or multi-level projects with more complex framing take longer. Weather and permitting timelines both factor in, so a realistic contractor will give you a range rather than a fixed date up front.

What should I check before hiring a contractor to build a deck in Kendall?

Confirm current Washington contractor licensing and insurance, and ask specifically what fastener grade and framing material they use for sustained moisture and salt exposure rather than a generic answer. It's also worth asking how they handle ledger flashing at the house connection, since that's one of the most common places a poorly built deck starts to fail.

Do you work with a specific composite decking brand, or is that up to the homeowner?

We build with whatever material fits the homeowner's budget and how they plan to use the space, including several composite and PVC product lines as well as traditional wood. What doesn't change between products is the framing, fastener, and drainage work underneath, since that's what actually determines how long any decking material lasts here.

What's the practical difference between capped composite and cellular PVC decking for a property like mine?

Capped composite has a wood-fiber core wrapped in a protective plastic shell, which resists moisture and fading well and costs less than PVC. Cellular PVC has no wood fiber at all, so it resists moisture even at cut edges, which can be worth the added cost on a shaded or particularly damp section of a property.

Does Kendall's more rural, inland setting change what a deck actually needs compared to properties closer to town?

The same salt air, driving rain, and long moss season affect the whole area, but Kendall's larger, often more wooded lots tend to hold more shade and moisture around a deck than a tighter in-town lot does. That usually shifts the priority toward stronger moss resistance and drainage detailing, and sometimes toward wind considerations on more open rural parcels.

Custom Decks in Kendall: Built for Local Conditions

Building a Custom Deck for Kendall's Climate

Kendall sits inland from the water, but that doesn't spare it from the same weather pattern that wears down outdoor structures across Whatcom County. Salt-tinged marine air still moves in on prevailing winds, driving rain still comes through hard during the wet months, and a long, damp moss season settles in and stays for most of the year. A deck has no roofline or siding to shield it from any of that. It sits outside in the open, taking the weather directly on every surface, which is exactly why a deck built here needs to be thought through differently than one built somewhere drier and more sheltered.

A lot of what determines whether a custom deck lasts in Kendall has nothing to do with how it looks on day one. It comes down to material choice, fastener grade, and drainage details that either hold up to sustained moisture and salt exposure or start failing quietly within a few seasons. This page walks through what a Kendall deck actually needs, what a correctly built deck involves, and how our process works from first visit to finished project.

What Kendall's Weather Does to a Deck

Salt-Tinged Air

Even away from the immediate shoreline, salt-laden air moves through inland Whatcom County on a regular basis, and it works on exposed metal wherever it lands. Fasteners, brackets, post hardware, and railing connectors are all vulnerable, and corrosion doesn't announce itself early. A screw or bracket can be losing holding strength well before it shows visible rust, which matters a great deal on a structure people stand and walk on every day.

Driving Rain

Rain in this region doesn't just fall straight down and run off. Wind pushes it sideways and up, forcing it into places a calm-weather design never accounts for — under railing caps, into ledger board connections, between deck boards that aren't gapped with drainage in mind. A deck that sheds water fine on a still day can still trap moisture the moment wind gets involved, and in Kendall that happens often enough that it needs to be part of the original design, not an afterthought.

A Moss Season That Runs Long

Mild, wet conditions give moss and mildew a long window to establish themselves, and a horizontal deck surface is one of the easiest places for that to happen. Unlike a wall, a deck holds standing water and stays damp between rain events, especially on shaded sections or north-facing portions of the yard. Any decking material with even a little surface porosity gives moss something to grip onto, and once it takes hold, a deck surface gets slick and starts degrading faster than it would otherwise.

Choosing the Right Decking Material for This Climate

Material choice matters more here than it would in a drier, more sheltered setting, because the difference between a well-suited product and a poorly-suited one shows up faster under sustained moisture and salt exposure. Most Kendall homeowners are choosing between wood, capped composite, and cellular PVC.

Wood

Pressure-treated lumber and cedar are the traditional option, and both can look excellent when new. Both also need regular sealing or staining to hold up against sustained moisture, and both are more susceptible to fastener corrosion issues over time in this air. Left unmaintained even a season or two, wood is usually the first material in this climate to show moss buildup, graying, and soft spots.

Capped Composite

Capped composite boards have a plastic shell wrapped around a wood-fiber composite core, which resists moisture absorption, staining, and fading far better than uncapped composite or raw wood. That cap layer is doing real work in a climate like this — it's the difference between a board that needs occasional washing and one that needs ongoing sealing to keep moisture out.

Cellular PVC

PVC decking contains no wood fiber at all, so there's nothing inside the board to absorb moisture, even at cut edges or fastener holes. It generally costs more than composite and can flex a bit more under heavy point loads, but for a shaded, moisture-heavy section of a Kendall property, some homeowners find the added cost worth the extra resistance.

Material	Handling Moisture & Salt Air	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 absorption at exposed fiber	Fair; more prone to buildup over time	Periodic cleaning
Cedar	Moderate — natural resistance, needs sealing	Fair when sealed and maintained	Regular oiling or sealing
Pressure-treated wood	Weak against sustained moisture over time	Poor without regular treatment	Regular sealing or staining

What a Correctly Built Deck Involves

The decking surface gets most of a homeowner's attention when picturing a new deck, but in this climate, the framing, fasteners, and drainage details underneath are what actually decide how long it lasts. A build done right here includes:

Framing material sized and rated for sustained moisture exposure, not a generic lumber spec pulled off the shelf
Corrosion-resistant fasteners and hardware throughout, since standard hardware starts losing strength in this air within a few seasons
Hidden fastener systems on the walking surface where the product supports them, reducing exposed metal and giving a cleaner finish
Correct board gapping so wind-driven rain and standing moisture can actually drain and dry between boards instead of pooling
Proper ledger board flashing at the house connection, one of the most common places moisture gets into a poorly built deck
Joist spacing matched to the specific decking product's span rating rather than a one-size-fits-all layout
Footings set to the correct depth for the site and soil conditions, not just deep enough to pass a casual look
Railing and post attachment sized for the actual exposure at the site, particularly on elevated decks or open, wind-exposed lots

Skip any one of those and the deck usually still looks fine when it's finished. The problems tend to show up a few winters later — a soft joist, a loosening railing post, or corrosion staining bleeding into the boards around a fastener.

Custom Design Considerations for Kendall Properties

Kendall's mix of larger, more wooded lots and open rural properties raises a few design questions that a stock deck plan doesn't account for. Heavier tree cover means more shade and slower drying, which shifts the priority toward moss-resistant materials and board spacing that actually clears water rather than just looking good on a sunny day. More open, less sheltered lots see more direct wind, which affects how solid a railing design can be versus how much a partial wind screen or glass panel is worth adding. Grade and drainage around the house matter just as much — a deck sited on a slope or low spot needs substructure and grading work that a flat, well-drained lot doesn't. None of these are decisions with one right answer for every property, which is a large part of why a custom design built around the specific site performs differently than a standard package dropped onto any lot.

Cost Factors Worth Understanding

Two bids for what looks like the same deck can land far apart, and the gap is usually a real difference in scope rather than one contractor padding the price.

Factor	What It Affects
Decking material	Upfront cost, moisture resistance, and long-term maintenance burden
Substructure and footing depth	Structural longevity and how well the deck holds up on this site's soil and grade
Fastener and hardware grade	How long connections resist corrosion before they start loosening
Hidden fastener systems	Surface finish and long-term exposed-metal corrosion risk
Size, shape, and elevation	Labor time, framing complexity, and stair or railing requirements
Site access and grading	Equipment needs and how much substructure prep the site requires

A written estimate that breaks these out separately tells you far more than a single lump-sum figure, and it's worth asking any contractor to walk through exactly what's included before you compare numbers.

How Our Process Works

We keep this straightforward, since a deck is a real structural investment and homeowners deserve to know what's happening at each stage.

Site visit: We walk the property to check drainage, grade, sun and wind exposure, and existing structure condition if it's a replacement.
Material and design discussion: We talk through decking options, layout, and railing style that fit the budget and how the space will actually get used.
Written estimate: You get an itemized bid covering substructure, fasteners, decking, railing, and any stairs or trim, not a single vague number.
Permitting: We handle the required Whatcom County permitting as part of the job rather than leaving it for you to sort out.
Substructure and framing: Footings, framing, and ledger flashing go in first, sized and fastened for what this specific site actually sees.
Decking, railing, and finish work: The surface, railing, and any stairs go on to product specification, followed by a final walkthrough and site cleanup.

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.

Rinse the surface periodically to clear salt residue, pollen, and organic debris before it works into the material
Keep the gaps between boards clear so water and airflow can move the way the design intends
Check railing hardware once a year for early corrosion or loosening, especially before the wet season sets in
Trim back overhanging branches or plants holding moisture and shade against the deck surface
Deal with any soft framing or standing water underneath right away — that's a structural issue, and it doesn't improve on its own

Why It Matters That We Already Work Kendall

A crew that mostly builds in drier or more sheltered parts of the county can still put together a competent-looking deck, but a Kendall project has variables that don't come up everywhere — fastener grade requirements from sustained salt exposure, wind loads that vary a lot between open and wooded lots, and a moss season that runs longer here than in a lot of other places. Working this area regularly means we're not guessing at those requirements on your project. We've seen which decking products actually hold up to Kendall's specific combination of conditions and which framing and fastener details are worth the extra time rather than an unnecessary upsell.

That familiarity also shows up in the smaller judgment calls on site — how to orient a deck for the wind and shade a particular lot actually gets, or being straightforward with you about what your property realistically needs versus what's just an added line item.
