How long does it typically take to build a deck?

A straightforward deck project usually takes one to two weeks from the start of framing to final decking and railing, though permit approval timelines from the county can add time before work even starts. Larger or multi-level decks, or ones requiring more complex footing work, take longer. We give you a realistic schedule once we've assessed the site.

What should I ask a contractor before hiring them for deck work?

Ask whether they pull permits and handle inspections themselves, what fastener and hardware standards they use, and whether they'll put footing depth and ledger flashing details in writing. Ask for proof of licensing and insurance, and be wary of anyone quoting a firm price before seeing the site in person.

Is composite decking actually worth the higher upfront cost?

For shaded or moss-prone lots, composite often pays for itself in avoided maintenance — no annual sealing, no sanding, and it resists the surface staining that wood picks up in wet climates. For sunnier, well-drained lots where you don't mind periodic sealing, treated wood or cedar can still be a solid, less expensive choice.

What's the difference between capped composite and PVC decking?

Capped composite has a wood-fiber core wrapped in a protective plastic shell, giving it a more natural look and feel at a moderate price point. Full PVC decking has no wood content at all, giving it the best moisture resistance and lightest weight, generally at a higher price.

Does a deck in Kendall need a different design than one closer to the Ferndale waterfront?

The core structural requirements — footings, code-compliant railings, proper flashing — don't change based on location. What does change is exposure: Kendall's inland, often shaded lots tend to deal more with moss and slow-drying ground, while waterfront areas deal more with direct salt air exposure on fasteners and finishes, so material and hardware choices get tailored accordingly.

Deck Building in Kendall: Built for This Corner of Whatcom County

Kendall sits inland from the coastal salt air that hammers the rest of Whatcom County, but that doesn't mean local decks get an easy ride. Between the long wet season, heavy morning dew off the foothills, and moss that colonizes anything shaded and damp, a deck built without this climate in mind starts showing problems within a few years — soft boards, rusted fasteners, slick surfaces, and ledger connections that were never properly flashed. We build decks in Kendall the way this area actually requires, not the way a generic build-anywhere crew would do it.

This page covers deck building specifically for Kendall homes: what the local conditions demand, what a correctly built deck involves from the ground up, and how we run the job from first call to final walkthrough.

What Kendall's Climate Does to a Deck

Kendall gets the same wet-season soaking as the rest of Whatcom County, plus its own microclimate quirks from being tucked closer to the foothills — more shade in places, slower-drying ground, and a longer moss season than open, sun-exposed lots closer to town. None of that is exotic, but it's exactly the kind of thing a deck design has to account for.

The Main Stress Points

Ledger board rot: where the deck attaches to the house is the single most common failure point when flashing and waterproofing are skipped or done wrong.
Moss and algae growth: shaded, north-facing, or tree-covered sections of a Kendall lot hold moisture longer, and moss on decking isn't just ugly — it's slippery and it traps water against the wood.
Fastener corrosion: standard hardware rusts and stains decking over time in a climate this wet; it needs to be matched to the material, not just whatever's cheapest.
Footing movement: saturated soil during the wet months can shift under-built footings over several seasons, leading to a deck that feels bouncy or slowly pulls away from the house.
End-grain saturation: cut ends of boards soak up water fastest, and if they aren't sealed or capped, that's where rot starts even on decking rated for outdoor use.

What a Correctly Built Deck Actually Involves

Footings and Framing

Everything starts below grade. Footings need to be sized and set below the frost line and rated for the actual load of the deck plus people, furniture, and snow load in a bad winter. In this soil and moisture environment, we don't shortcut footing depth or diameter just to save a half-day of digging — that's the part of the job nobody sees again once the decking goes on, and it's the part that determines whether the deck is solid in ten years or wobbly in three.

Ledger Attachment and Flashing

If the deck attaches to the house, the ledger connection gets proper flashing that sheds water away from the band joist and wall sheathing, plus structural fasteners rated for the load — not just deck screws. This is the single spot inspectors and insurance adjusters look at hardest, and for good reason: get it wrong and water gets behind your siding, not just under your deck.

Joist Layout and Spacing

Joist spacing needs to match the decking material's span rating. Composite and PVC decking often need tighter joist spacing than solid wood — installing composite over a wood-spec frame is a common corner-cutting mistake that leads to bounce and premature sagging.

Fasteners and Hardware

All structural hardware should be hot-dip galvanized or stainless, rated for ground contact and treated lumber contact (modern treated lumber's chemical makeup corrodes standard electroplated fasteners faster than older formulations did). Hidden fastener systems for decking need to be matched to the specific board profile, not forced to fit.

Drainage Under and Around the Deck

Grading beneath the deck should carry water away from the house foundation, not let it pool. On lower or shaded Kendall lots this matters more than usual — standing water under a deck is what keeps the whole structure damp long after a storm has passed and is a major contributor to the moss and mildew problem homeowners fight every spring.

Decking Material Options for This Climate

There's no single "best" decking material — there's a right tradeoff for your budget, your sun exposure, and how much maintenance you're willing to do. Here's how the common options actually perform in Whatcom County conditions.

Material	Moss/Moisture Resistance	Maintenance	Typical Lifespan	Notes
Pressure-treated wood	Fair — needs sealing	Annual cleaning + sealing recommended	15–20 years with upkeep	Lowest upfront cost; most sensitive to skipped maintenance
Cedar	Good — naturally rot-resistant	Periodic staining/sealing	20–25 years with upkeep	Natural look many homeowners want; still needs seasonal care
Composite decking	Very good — won't rot	Occasional washing to prevent surface moss/algae	25–30+ years	Higher upfront cost, no staining or sealing ever needed
PVC/capped polymer decking	Excellent — fully moisture-sealed	Low — wash as needed	30+ years	Best moisture performance; premium price point

Composite and PVC decking have become the more common choice for shaded or heavily wooded Kendall lots specifically because they don't give moss anything to grip into the way porous wood surfaces do — surface growth wipes off instead of embedding. Wood is still a legitimate choice if you're willing to stay on top of sealing every couple of years; it's a maintenance commitment more than a durability weakness.

Railings, Stairs, and Code Requirements

Whatcom County building code sets specific requirements for deck height, railing height, baluster spacing, and stair geometry, and a deck over a certain height off grade requires a permit and inspection. We handle the permit process as part of the job rather than leaving it on the homeowner, and we build to code minimums as a floor, not a target — the guardrail and stair details are exactly where a deck either passes inspection cleanly or gets flagged and delayed.

How We Handle a Kendall Deck Project

On-site assessment: we walk the actual lot, check sun/shade exposure, existing drainage, soil condition, and how the deck will tie into the house.
Design and material selection: we go over size, layout, and decking material tradeoffs based on your budget and how much maintenance you want to take on long-term.
Permitting: we pull the required Whatcom County permit and schedule inspections as part of the project timeline, not as an afterthought.
Footings and framing: proper depth footings, correctly flashed ledger, joist spacing matched to your decking choice.
Decking, railing, and stairs: installed to the fastener and code spec for the material chosen.
Final walkthrough: we go over the finished deck with you, including basic maintenance expectations for the material you picked.

Why Hire a Crew That Already Works in Kendall

A deck built by a crew unfamiliar with this specific area tends to make the same mistakes: standard fastener specs pulled from a warmer, drier climate; drainage plans that assume soil drains faster than Whatcom County clay actually does; decking material recommendations that ignore how much shade and moss exposure a given lot actually gets. A crew that already builds in Kendall and the surrounding Ferndale area has already seen which details matter here and doesn't have to learn that on your project.

We also know the local permitting process and inspection expectations, which keeps the project moving instead of stalling on paperwork or a failed rough-in inspection.

Maintenance Checklist for a Kendall Deck

Whatever material you choose, a little seasonal attention goes a long way in this climate:

Sweep debris and standing leaves off the deck surface regularly, especially under overhanging trees
Check and clear drainage paths underneath and around the deck before the wet season starts
Wash the surface at least once a year to knock back moss and algae before it embeds
Inspect the ledger board area and flashing annually for any signs of water staining
For wood decking, reseal or restain on the schedule the product calls for — don't wait until it looks bad
Check railing and stair connections for looseness each spring

What This Costs

Deck costs vary a lot based on size, material, height off grade, and how much structural work the ledger and footings require. Pressure-treated wood decks are the lowest upfront cost option; composite and PVC decking run higher upfront but cost less in maintenance over the deck's life. Rather than throw out a number that doesn't fit your specific lot, we'd rather walk the site and give you an honest, itemized estimate based on what your project actually needs.
