How long does a custom deck build typically take from start to finish?

A straightforward deck usually takes one to two weeks of on-site work once permits are approved, though larger or multi-level designs take longer. Permitting itself can add several weeks depending on the county's review queue. Weather is the biggest variable in Whatcom County, since sustained rain can push back footing and framing work.

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

Confirm they're licensed, bonded, and insured, and ask specifically whether they'll handle the permit and inspection process for you. Ask how they flash the ledger board and what fasteners they use, since those two details predict most long-term problems. A written scope with materials, timeline, and payment terms spelled out is worth insisting on before any work starts.

Is composite decking worth the extra cost over pressure-treated wood in a place like Kendall?

It depends on how much maintenance you want to take on. Composite costs more upfront but resists moisture and moss better with far less annual upkeep, which matters in a climate with a long wet season. Wood is a reasonable choice too, as long as you're realistic about committing to yearly cleaning and sealing.

What fasteners and hardware do you use to keep a deck from rusting or staining in this climate?

We use fasteners and structural connectors rated for exterior, high-moisture exposure, along with corrosion-resistant hardware at load-bearing connections like joist hangers and ledger bolts. Standard uncoated fasteners rust and streak the decking around them within a couple of wet seasons out here, so this isn't a place to cut corners. It's a small cost difference that has a big effect on how the deck looks and holds up over time.

Since Kendall isn't inside Ferndale city limits, who handles the building permit?

Deck permits and inspections for Kendall go through Whatcom County's permitting process rather than the City of Ferndale, since it's an unincorporated area. We prepare and submit the permit and coordinate inspections at each build stage as part of the job, so you don't have to sort out which office to work with.

Custom Decks in Kendall, WA: Built for Whatcom County Weather

Building Decks for Kendall's Weather, Not Just Its View

Kendall sits back from the coast, tucked into the foothill country of eastern Whatcom County, and that changes what a deck actually needs to hold up over time. It's a different build than a deck going in along the Ferndale waterfront or down in Bellingham. The wood, hardware, and framing choices that work fine in a drier climate start failing here within a few seasons if they weren't specified for this ground and this weather. We build decks around Ferndale and out into communities like Kendall because we live with the same rain and the same long stretch of gray months everyone else here does. That matters more than most homeowners realize until they're dealing with a deck that's soft underfoot or graying unevenly after three winters.

What a Deck in Kendall Is Actually Up Against

Rain That Doesn't Let Up

Whatcom County gets a long, steady rainy season, and properties closer to the foothills — like much of the Kendall area — often see even more total precipitation than homes right on the coast. That's not a dramatic storm event problem; it's a slow, cumulative moisture problem. Water sits in end grain, works into fastener holes, and pools on any surface that wasn't sloped or gapped correctly the first time. A deck built without that in mind doesn't fail all at once. It fails quietly, board by board, over several winters.

Moss, Algae, and Shade

Kendall's rural, wooded character is part of what makes it a nice place to live, but tree cover and shade are exactly what moss and algae need to take hold on a deck surface. Once moss establishes itself in the grain of a board or in the gaps between boards, it holds moisture against the wood constantly, even on the rare dry day. Left alone through a full moss season, that turns a slip hazard into a rot problem underneath the surface.

Soil and Site Conditions

Lots out toward Kendall vary a lot more than in-town Ferndale lots — some are heavier clay that drains slowly, some are rockier, and grading can be uneven on acreage or wooded parcels. That directly affects footing depth, drainage planning around the deck's perimeter, and sometimes how the structure needs to be engineered to sit level on a site that isn't flat. A generic footing plan pulled from a catalog doesn't account for any of that.

Decking Material Options for This Area

There's no single "best" decking material — there's a best material for your budget, your maintenance appetite, and how much shade and moisture your specific site deals with. Here's how the common options actually perform in a climate like ours.

Material	Moisture & Moss Resistance	Maintenance	Typical Lifespan
Pressure-treated wood	Good if sealed and maintained; poor if neglected	Annual cleaning and re-sealing/staining	15-20 years with upkeep
Cedar	Naturally rot- and insect-resistant, but still needs sealing	Regular cleaning and periodic sealing to hold color	15-25 years with upkeep
Composite decking	Very good; won't rot, resists moss better on cap-stock boards	Occasional washing, no staining or sealing	25-30+ years, often warrantied
PVC decking	Excellent; fully synthetic, minimal moisture absorption	Lowest maintenance of the group	30+ years, typically warrantied

Composite and PVC cost more up front, and we tell homeowners that plainly rather than talk them into it. But in a climate that stays wet for months at a stretch, the lower-maintenance materials often pay for themselves in avoided re-staining, moss removal, and board replacement over the life of the deck. Wood is still a good choice for a lot of Kendall homes — it just needs a realistic maintenance plan, which we'll walk through with you.

The Structural Work That Actually Determines How Long a Deck Lasts

The decking surface is what you see, but the framing underneath is what decides whether the deck is still solid in fifteen years. A few things we don't shortcut on any deck we build here:

Footing depth and bearing. Footings are sized and set based on your actual soil conditions, not a one-size assumption, especially on sites with clay or uneven grading.
Ledger board flashing. Where the deck attaches to the house is the single most common source of hidden rot on older decks. Proper flashing keeps water from tracking behind the ledger and into the house framing.
Joist spacing and hangers. Correctly spaced joists with rated hangers, not just nailed connections, carry load properly and resist the sag that shows up over time on undersized framing.
Corrosion-resistant fasteners and hardware. Standard fasteners rust and stain the decking around them within a couple of wet seasons. We use fasteners and structural hardware rated for exterior, high-moisture use.
Proper drainage slope. A deck surface needs a slight pitch away from the house so water sheds instead of pooling on the boards or backing up against the siding.

None of this is visible once the deck is finished, which is exactly why it's the part worth asking a contractor about before you hire them.

Permits, Setbacks, and Whatcom County Code

Kendall is outside Ferndale's city limits, in unincorporated Whatcom County, so deck permits and inspections for homes out here go through the county rather than the city. That affects everything from guardrail height requirements to setback distances from your property line, and the process can catch homeowners off guard if they assumed it worked the same as an in-town Ferndale permit. We handle the permit submission and coordinate inspections as part of the build, so you're not the one figuring out which jurisdiction to call.

A few code basics that apply to most residential deck builds in the county:

Guardrails are required once a deck surface is a certain height above grade, with minimum height and baluster spacing rules.
Footings need to be set to the depth required for your soil and load conditions, not just "deep enough."
Decks attached to the house typically require a permit regardless of size once they exceed a low threshold height.
Setback requirements from property lines apply to decks the same as other structures, which matters more on some of the larger or irregularly shaped lots common around Kendall.

Our Process, Start to Finish

Site visit and measurements. We walk your property, look at grading, drainage, sun and shade exposure, and how the deck will tie into the house.
Design and material selection. We go over layout, decking material, and railing options based on your budget and how much upkeep you actually want to do.
Permitting. We prepare and submit what's needed for Whatcom County approval and schedule inspections at the right build stages.
Demolition, if needed. If there's an old deck to remove, we take it out and check the house framing behind it for any hidden moisture damage before building new.
Footings and framing. This is the stage that determines the deck's lifespan, and it's inspected before decking goes down.
Decking, railing, and finish work. Boards, railing, stairs, and any trim or finish work go in, with attention to fastening and gapping for proper drainage.
Final walkthrough. We go over the finished deck with you, including how to care for whatever material you chose through the wet months ahead.

Maintenance Through a Long Moss Season

Whatever material you choose, a little seasonal upkeep goes a long way in this climate. A simple routine most Kendall homeowners can keep up with:

Sweep leaves and debris off the deck regularly in fall before they trap moisture against the boards.
Keep gutters and downspouts clear so roof runoff isn't dumping directly onto or next to the deck.
Clean the surface at least once a year with a cleaner suited to your decking material — a pressure washer alone can damage wood grain or composite cap-stock if used incorrectly.
Re-seal or re-stain wood decking on the schedule the product calls for, typically every one to two years depending on sun exposure.
Check fasteners, railing connections, and stair stringers annually for looseness or rust staining.
Trim back nearby vegetation to improve airflow and sun exposure, which slows moss regrowth.

Why Hiring a Crew That Already Works Kendall Matters

A deck design that works fine in a drier region, or even just closer to the water where salt-laden air and building patterns are different, doesn't automatically translate to a wooded, foothill site out toward Kendall. Soil varies lot to lot, shade patterns are heavier, and the permitting process runs through the county rather than the city. A crew that already builds in this area knows to plan footings for the soil you actually have, flash and frame for a wet season that runs long, and handle the county permit process without it becoming your problem to sort out. That local familiarity is the difference between a deck that's still solid in fifteen years and one that needs real repair work in five.
