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

A straightforward deck usually takes one to two weeks once construction starts, though permitting can add several weeks before that depending on the scope. Larger or multi-level decks, or ones requiring engineered footings, take longer. We'll give you a realistic timeline specific to your project during the on-site assessment.

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

Confirm they're licensed and insured, ask whether they pull permits themselves, and get specifics in writing on hardware and flashing rather than a vague verbal promise. It's also worth asking how they've handled decks in wet, salt-exposed areas specifically, since that experience shows up in the details. A contractor who can't answer clearly is worth a second look.

Is composite decking worth the extra cost over pressure-treated wood?

It depends on your priorities — composite costs more upfront but needs far less upkeep over its life, which matters in a climate with a long wet and mossy season. Pressure-treated wood is more affordable initially but requires regular sealing to hold up well. Both are legitimate choices; it's really a maintenance-versus-budget decision.

What's the difference between composite and PVC decking?

Composite decking blends wood fiber with plastic and offers a natural wood-grain look with low maintenance. PVC decking is fully synthetic, tends to resist moisture even more completely, and often costs somewhat more. Both perform well in wet climates; the choice usually comes down to appearance preference and budget.

Does a deck in Custer need different permitting than one in Blaine proper?

Permitting requirements are generally set at the county or city level depending on your exact location, and Custer properties may fall under Whatcom County jurisdiction rather than city of Blaine rules. The requirements themselves — footing depth, guardrail height, attachment details — are similar, but which office issues the permit can differ. We confirm the correct jurisdiction for your property before applying.

Deck Building in Custer & Blaine, WA

Building a Deck That Holds Up in Custer

Custer sits close enough to the water and open farmland that decks here take a different kind of beating than decks built twenty miles inland. Salt-laden air off the Strait, driving rain that comes in sideways more often than straight down, and a moss season that can stretch from October into April all work against a deck that wasn't built with this specific climate in mind. A deck that would be perfectly fine in a drier part of the state can start showing problems here within a couple of seasons if the fasteners, ledger flashing, or decking material weren't chosen with Whatcom County weather in mind.

We build decks for homes in Custer and the surrounding Blaine area, and the details we pay attention to are shaped by what actually fails out here: corroded hardware, moss-slicked boards, water trapped behind ledger boards, and structural framing that dries out slower than it should because it never gets a full week of sun between storms.

What Custer's Climate Does to a Deck

Salt Air and Metal Fasteners

Custer's proximity to Boundary Bay and the Strait of Georgia means the air carries salt further inland than people expect. Standard galvanized fasteners and connectors can start corroding faster here than they would in a landlocked town, and once a joist hanger or ledger bolt starts rusting, it's not just cosmetic — it's a structural problem that's hard to spot until it's advanced. We use stainless or heavy-duty coated hardware rated for coastal exposure on every deck we build in this area, not as an upsell, but because it's what the environment actually requires.

Driving Rain and Ledger Board Failure

Most deck failures we see aren't dramatic collapses — they're slow rot starting at the ledger board, the horizontal member that attaches the deck to the house. When rain comes in at an angle, as it often does here, water finds its way behind poorly flashed ledger connections and sits there. Wood framing that stays damp for weeks at a time without drying out is exactly how you get soft, rotted framing hidden behind a deck that still looks fine on the surface.

Moss and the Long Wet Season

A moss season that runs half the year means horizontal surfaces — deck boards, stair treads, railing caps — stay damp longer and grow moss faster than most homeowners expect. Moss isn't just unsightly; it holds moisture against the wood or composite surface and turns a deck into a slip hazard, especially on stairs. Board spacing, surface texture, and drainage underneath the deck all affect how much moss you'll fight every winter.

What a Correctly Built Deck Includes

A deck that's going to last in this climate isn't just about picking a nice-looking board. It comes down to a handful of details that are easy to skip and expensive to fix later.

Proper ledger board flashing that directs water away from the house rather than behind the deck attachment
Corrosion-resistant fasteners and structural connectors rated for coastal/marine exposure
Adequate air gap and drainage beneath the deck surface so framing can actually dry between storms
Footings set below frost depth and sized correctly for the soil conditions on your lot
Board spacing and orientation that lets water shed quickly instead of pooling
Stair and railing hardware built to current code, not grandfathered from an older design
A decking material choice that matches how much maintenance you actually want to do

Decking Material Options for This Climate

There's no single "right" material for every homeowner — it depends on budget, how much upkeep you're willing to do, and how the deck will be used. Here's how the common choices compare specifically for a wet, moss-prone, salt-air environment like Custer's.

Material	Moisture Behavior	Moss/Slip Concern	Maintenance
Pressure-treated lumber	Resists rot when properly sealed and maintained	Moderate — needs periodic cleaning	Annual sealing/staining recommended
Cedar	Naturally rot-resistant, but softer surface	Higher — grays and can hold moss without upkeep	Regular sealing to maintain appearance and lifespan
Composite decking	Doesn't absorb water like wood; very stable in wet climates	Lower with textured/grooved profiles	Occasional washing, no sealing/staining
PVC decking	Fully water-resistant, unaffected by moisture cycling	Low with the right surface texture	Lowest — mostly rinsing

Composite and PVC decking generally cost more upfront but ask much less of you over the years, which matters in a climate where a wood deck's maintenance schedule isn't optional if you want it to last. Pressure-treated and cedar remain solid, honest choices for homeowners who want a traditional look and don't mind staying on top of sealing.

A Note on Product Choices

We're selective about which decking brands and fastening systems we install, and it's not because any particular product on the market is bad — it's that some systems are more forgiving of Whatcom County's wet cycles than others, and some require installation tolerances that are easy to get wrong. We install what we've found holds up reliably here and stand behind that choice with you before work starts, not after a problem shows up.

How Our Deck Building Process Works

1. On-Site Assessment

We walk the property, look at drainage patterns, sun and shade exposure, existing structure if you're replacing a deck, and how the deck will connect to your home. This is also where we talk through what you actually want to use the deck for — entertaining, grilling, a quiet spot off a bedroom — because that shapes size and layout decisions.

2. Design and Material Selection

We go over decking material, railing style, and layout options, along with straightforward pros and cons for each given your budget and how much maintenance you want to take on. No pressure toward the most expensive option — just a clear picture of trade-offs.

3. Permitting

Most deck projects in Whatcom County require a permit, particularly for anything attached to the house or built above a certain height. We handle that process so you don't have to chase it down yourself.

4. Construction

Framing first, with attention to ledger flashing and hardware as described above, then decking, railing, and stairs. We build in the drainage and airflow details that matter for this climate as a standard part of the job, not an add-on.

5. Final Walkthrough

We walk the finished deck with you, point out anything you should know about care and maintenance for the material you chose, and make sure everything meets the standard we set at the start.

New Build vs. Deck Replacement

A lot of what we do in Custer is replacing decks that were built years ago without today's flashing standards or corrosion-resistant hardware. If your existing deck feels soft in spots, has visible rust streaks around fasteners, or has a persistent moss problem no amount of cleaning fixes, those are usually signs the underlying structure — not just the surface — needs attention. Sometimes that means a full rebuild; sometimes the footings and framing are sound and only the decking and railing need replacing. We'll tell you honestly which situation you're in rather than defaulting to the bigger job.

Questions to Ask Before You Hire a Deck Builder

Do they carry current liability insurance and pull the required permits themselves?
Will they specify corrosion-resistant hardware in writing, not just verbally?
Do they explain how they'll handle ledger board flashing before work starts?
Can they show you examples of decking materials in person, not just a catalog photo?
Do they give you a clear maintenance expectation for whatever material you choose?

Why Hire a Crew That Already Works in Custer

A deck builder who works this specific stretch of Whatcom County has already seen how salt air corrodes hardware, how driving rain finds weak flashing, and how a long moss season punishes the wrong surface texture. That's not something you can fully learn from a general contracting background somewhere drier — it comes from building and repairing decks in this exact climate, on this exact coastline, year after year. When we spec hardware, flashing details, and decking material for your Custer property, it's based on what we've watched hold up here, not a generic recommendation that happens to look good on paper.
