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

A straightforward deck replacement usually takes one to two weeks once permits are approved, depending on size and weather. Larger or multi-level decks with extensive railing or stair work take longer. Permit review time in Whatcom County can add to the front end, so we build that into the schedule upfront.

What should I ask a contractor before hiring them to build my deck?

Ask whether they pull permits, what specific fastener and hardware grade they use, and whether they'll put material and hardware specs in writing rather than a vague lump-sum quote. Also ask how they handle ledger flashing, since that's the detail most likely to cause hidden problems later. A contractor who can answer these plainly, without hedging, is usually one who's done the work correctly before.

Is composite decking actually worth the extra upfront cost over wood?

It depends on how much maintenance you want to do. Composite costs more initially but skips the sealing and staining cycle that wood needs every one to three years, and it won't rot even if drainage underneath isn't perfect. For a low, shaded, or salt-exposed deck, that trade-off often pays for itself in avoided maintenance over time.

Why do you specify stainless or coated hardware instead of standard deck screws?

Standard exterior screws and joist hangers corrode faster in salt-influenced coastal air, and corroding hardware weakens structural connections while staining the wood around it. Stainless steel or properly coated hardware costs more but is built to handle that exposure, which matters more the closer you are to the water.

Does a deck in Blaine need anything different from a deck built further inland in Whatcom County?

The core construction — framing, footings, code compliance — is the same everywhere in the county. What changes is the degree of attention paid to salt-air corrosion resistance, drainage, and airflow underneath the deck, since Blaine's coastal exposure accelerates all three compared to a more sheltered inland lot.

Blaine Deck Building — Built for Bellingham's Coastal Weather

Why Blaine Decks Take a Different Kind of Beating

Blaine sits close enough to the water that salt air is a real factor in how a deck ages, not just a talking point. Add in the long stretch of wet months that Whatcom County gets every fall through spring, plus the driving rain that comes sideways off the Strait during winter storms, and you've got conditions that punish decks built to a generic spec. A deck that would hold up fine in a dry inland climate can start showing corrosion on fasteners, soft spots in framing, and a slick coat of moss within a few seasons out here if it wasn't built with this specific weather in mind.

We're not describing anything unusual or alarming — this is just what coastal Whatcom County does to exterior wood and hardware over time. The point of building it right the first time is that you don't have to think about it again for a long while.

What a Correct Deck Build Actually Involves

A deck is a structure first and a surface second. Most of the problems we get called out to fix on other people's decks trace back to shortcuts taken below the boards, where nobody sees them until something fails.

Ledger Attachment and Flashing

If your deck attaches to the house, the ledger board connection is the single most important detail on the whole project. It has to be bolted (not just nailed) into the house framing, and it needs proper flashing that sheds water away from the band joist and siding — not just a bead of caulk. With the amount of driving rain Bellingham gets, a poorly flashed ledger is where rot starts, and it's usually hidden behind the rim joist where you won't see it until the deck starts to feel spongy near the house.

Footings and Post Bases

Footings need to go below frost depth and bear on undisturbed, properly compacted soil — not fill dirt or a shortcut poured on top of sod. Post bases should hold the post above the concrete, not embed it, so water doesn't wick up into the wood grain. This is basic, but it's also the part that's easiest to skip when a crew is trying to move fast, and it's the part that's hardest to correct after the fact.

Choosing a Decking Material for This Climate

There's no universally "best" decking material — there's a best fit for your budget, your maintenance appetite, and how close you are to salt air and standing moisture. Here's how the common options actually compare once you factor in local conditions.

Material	Upfront Cost	Maintenance	How It Handles Moss & Moisture
Pressure-treated wood	Lowest	Annual cleaning, periodic sealing/staining	Absorbs moisture, needs airflow underneath and regular cleaning to keep moss from gaining a foothold
Cedar	Moderate	Regular sealing to hold color and resist checking	Naturally more rot-resistant than treated pine but still needs airflow and cleaning
Composite decking	Higher	Occasional washing, no staining/sealing	Won't rot, but can still grow surface algae/moss if it stays shaded and damp — needs the same airflow underneath
PVC/capped polymer	Highest	Lowest — occasional washing	Fully non-absorbent surface, most resistant to moss staining, best fit for heavily shaded or damp yards

We'll walk through this table with you against your actual site — how much sun the deck gets, how close it sits to grade, and what you want to be doing (or not doing) to it every spring.

Fasteners and Hardware Near Salt Air

This is one of the most overlooked parts of deck construction in a coastal town, and it's where a lot of otherwise decent decks fail early. Standard fasteners corrode faster near salt air, and once a screw head or joist hanger starts rusting, it stains the wood around it and weakens the connection it's supposed to hold.

The fix isn't complicated — it's just a matter of not cutting the corner:

Stainless steel or high-grade coated fasteners rated for coastal/salt exposure, not standard exterior-grade screws
Hot-dip galvanized or stainless joist hangers and structural hardware, matched to whatever fastener type is going into them (mixing metals causes its own corrosion problems)
Fastener spacing and placement that follows the decking manufacturer's spec, since composite and PVC boards have specific requirements for expansion and contraction
Flashing tape or a moisture barrier on top of joists, so screws aren't driving directly into bare, exposed wood grain that will trap water

None of this is visible once the deck is finished. It's the kind of thing you have to trust your contractor got right, which is part of why we're upfront about exactly what hardware and fasteners go into a Blaine deck before we start.

Managing Moss, Algae, and Drainage

Whatcom County's moss season is long, and a deck with poor airflow underneath or poor drainage around it will grow a green film faster than most homeowners expect. This isn't a defect in any particular material — it's just what happens when organic spores land on a damp, shaded surface for months at a time. The building has to work with that reality instead of ignoring it.

Board Spacing and Airflow

Gapping between boards needs to account for both drainage and the material's expansion characteristics. Too tight, and water sits on the surface and in the gaps; too loose, and you get an uneven, less comfortable deck surface. Composite and PVC manufacturers publish specific gap tolerances, and we follow them rather than eyeballing it.

Under-Deck Drainage and Grading

Low decks close to grade are the worst offenders for moss and rot, because there's nowhere for water to go and little airflow to dry things out between rains. Where the site allows it, we grade and drain the ground under the deck so water moves away instead of pooling, and we leave enough clearance under the framing for air to actually circulate. On taller decks, an under-deck drainage system can also keep the space below usable and dry.

Railings, Stairs, and Code Requirements

Railings and stair details aren't optional extras — Whatcom County follows the state building code's requirements for guard height, baluster spacing, and stair rise/run, and those requirements exist because they prevent real injuries. We build to code as the floor, not the ceiling, and we handle the permit and inspection process as part of the job so you're not the one chasing down a signature at the end.

Beyond code minimums, railing material matters for the same reasons decking material does — wood railings need the same maintenance commitment as wood decking, while metal or composite rail systems trade a higher upfront cost for less upkeep in wet, salty air.

Our Process, Start to Finish

A deck project runs smoother when everyone knows what's happening and when. Here's the general shape of how we run a Blaine deck build:

On-site visit to look at grade, drainage, sun exposure, and existing structure (for replacements) before we recommend anything
A written estimate that spells out framing hardware, decking material, and fastener specs — not just a total price
Permit pulled and submitted where required, so the project is inspected and documented properly
Demolition and disposal of the old deck, if this is a replacement, with the site left clean
Framing and footings built first, with ledger flashing and structural hardware installed to spec before any decking goes down
Decking, railing, and stairs installed per the manufacturer's fastening and spacing requirements
Final walkthrough with you before we call it finished

We keep you in the loop at each stage rather than disappearing until the job's done, and if weather pushes a step back a day or two — which happens here — we tell you rather than let you wonder.

Maintenance Timeline After the Build

Whatever material you choose, a little regular attention keeps a Blaine deck looking and performing the way it should. Roughly:

Task	Wood Decking	Composite/PVC Decking
Surface cleaning / moss removal	1–2x per year	1x per year, more if heavily shaded
Sealing or staining	Every 1–3 years	Not required
Hardware/fastener inspection	Annually	Annually
Gutter/drainage check near deck	Before wet season	Before wet season

None of this is a heavy lift, but skipping it — especially the moss removal and drainage checks before the wet season sets in — is how a well-built deck starts looking neglected years before it actually needs to be replaced.

Why It Matters That We Already Work This Area

A deck built to a generic national spec will hold together, but it won't necessarily be built for what Blaine actually throws at it. We already know how far salt air travels inland here, how long the moss season runs, and which fastener and flashing choices hold up versus which ones start showing rust and staining within a couple of winters. That's not a sales pitch — it's the reason the framing and hardware decisions above look the way they do. A crew that only shows up for one job doesn't have that context, and it shows up later in the form of callbacks nobody wants.
