Anacortes Siding Building a Deck That Actually Holds Up in Burlington
Burlington sits in the flat, damp middle of Skagit County, close enough to the water and the Sound's weather patterns that homes here deal with the same punishing combination as the rest of the Anacortes area: salt-tinged air, long stretches of driving rain, and a moss season that can run from October well into April. A deck built to a generic national spec will survive a dry climate just fine. It will not survive here without some adjustments. A custom deck for a Burlington home has to be designed around moisture management first and looks second — not because looks don't matter, but because a deck that traps water or grows moss underfoot is a deck you'll be repairing or replacing years early.
This page is about what that actually means in practice: the materials that hold up, the structural details that get skipped on cut-rate jobs, and the process we follow so a Burlington deck is still solid a decade or two from now.
What the Local Climate Actually Does to a Deck
Driving Rain and Standing Water
Skagit County doesn't just get rain — it gets sustained, wind-driven rain that finds its way into every gap, seam, and fastener hole a deck offers. Water that would bead off and run away on a calm day gets pushed sideways into ledger boards, railing posts, and stair stringers. Any place where wood meets wood, or wood meets the house, is a place moisture will collect if it isn't detailed correctly.
Moss Season
A long, wet, mild winter is exactly what moss needs to establish itself, and a deck surface that stays shaded or doesn't drain well will grow a slick green film on the boards and in the gaps between them. Beyond the slip hazard, moss holds moisture directly against the decking material, which accelerates rot in wood and can stain even composite surfaces if it's left to sit.
Salt Air
Being this close to Puget Sound means airborne salt is a real factor, even a few miles inland. Salt-laden moisture is harder on metal fasteners, hardware, and railing components than fresh water alone — it speeds up corrosion in anything that isn't properly rated for coastal exposure.
Where Decks Actually Fail Around Here
After years of working on homes throughout the Anacortes and Skagit County area, the failure points we see are consistent. Almost none of them are decking board problems — they're structural and detail problems hiding underneath a deck that still looks fine on the surface.
- Ledger board rot — the board that attaches the deck to the house, when flashed poorly or not flashed at all, lets water track behind the siding and into the rim joist.
- Hidden joist and beam rot — framing that looks solid from below but has been absorbing moisture at joist hangers and beam pockets for years.
- Corroded fasteners — nails or screws not rated for treated lumber or coastal exposure, which corrode, stain the wood, and eventually let boards work loose.
- Undersized or shallow footings — posts sitting on footings that shift with our wet-clay soil conditions over time.
- Moss buildup between boards — a drainage and gapping problem more than a cleaning problem.
Choosing the Right Decking Material for This Climate
There is no single "best" decking material — there's a best material for your budget, your maintenance tolerance, and how much sun or shade your deck gets. Here's how the common options actually perform in a Burlington-area climate:
| Material | Moisture Performance | Maintenance | Typical Lifespan Here |
|---|---|---|---|
| Pressure-treated lumber | Good if sealed and maintained; prone to cupping and checking if neglected | Needs re-sealing every 1-2 years in this rainfall | 15-20 years with upkeep |
| Cedar | Naturally rot-resistant but still needs sealing against constant moisture | Annual cleaning and periodic sealing recommended | 15-20 years with upkeep |
| Composite decking | Excellent — doesn't absorb water or rot, though moss can still grow on the surface film | Periodic washing to prevent moss and algae staining | 25-30+ years |
| PVC decking | Excellent — fully moisture-resistant material | Low; occasional washing | 25-30+ years |
We don't push one product on every job. What we won't do is install a decking material in a way that fights its own moisture behavior — for example, tight-gapping composite boards in a shaded, low-airflow area, or leaving pressure-treated lumber unsealed through its first wet season. The installation detail matters as much as the material choice.
The Structural Details That Actually Determine Deck Lifespan
Ledger Attachment and Flashing
Where the deck meets the house is the single most important detail on the entire structure. We use proper flashing — installed so water is directed out and away from the house framing rather than behind it — and structural fasteners rated for the load and for treated lumber's chemical makeup.
Footings Sized for Local Soil and Frost Conditions
Footing depth and sizing need to match both the load of the deck and the frost and soil conditions specific to the site, per the local building department's requirements. We don't guess at this or reuse a one-size-fits-all footing spec — soil on a Burlington lot can vary from one side of a yard to the other.
Joist Protection
Covering the tops of joists and beams with a butyl or similar protective tape before decking goes down keeps fastener penetrations from becoming entry points for water into the framing. It's a small step that gets skipped constantly on lower-bid jobs, and it's one of the cheapest ways to add years to a deck's structural life.
Drainage and Airflow Underneath
A deck built low to the ground or over poorly graded soil traps moisture underneath, which speeds up both framing rot and moss growth on the surface above. Proper grading, gapping, and in some cases a drainage system underneath a raised deck all factor into a Burlington-specific design.
Hardware and Fasteners for Coastal Exposure
Given the salt air in this area, we spec fasteners and structural hardware rated for the corrosion resistance the site actually needs — not just the minimum requirement for treated lumber contact. Mismatched or under-rated hardware is one of the most common causes of premature staining, streaking, and eventual fastener failure we see on older decks in this region.
Our Custom Deck Process
- On-site assessment — we look at drainage, sun/shade exposure, soil conditions, and how the deck will tie into your home before any design work starts.
- Design and material selection — sized to your budget, your maintenance preferences, and how the space will actually be used.
- Permitting — we handle the permit application and inspections required by the local building department so the structure is documented and code-compliant.
- Footings and framing — built to the load and soil conditions of your specific lot, not a generic template.
- Decking, railing, and finish work — installed with the moisture-management details above, not just fastened down and called finished.
- Final walkthrough — we go over maintenance expectations for whatever material you chose so there are no surprises in year two or three.
Permits and Code in Burlington and Skagit County
Most custom deck projects above a certain height or attached to the structure of the home require a permit and inspection through the local building department. This isn't paperwork for its own sake — inspections catch footing depth, ledger attachment, and railing height issues before they're buried under decking boards. We handle this process as part of the job rather than treating it as an extra step, because a deck built without the required permits can create real problems at resale.
Keeping a Custom Deck Healthy Through the Wet Season
Whatever material you choose, a little seasonal attention goes a long way in a climate like ours. A simple annual routine keeps moss from getting a foothold and catches small problems before they become structural ones:
- Sweep debris and leaf litter out of board gaps before the fall rains set in
- Wash the surface at least once a year to remove early moss and algae growth
- Check railing posts and stair stringers for movement or soft spots each spring
- Re-seal wood decking on the manufacturer's recommended schedule, not just when it looks dry
- Clear gutters and downspouts near the deck so runoff isn't draining directly onto or under it
- Look underneath the deck once a year for standing water or signs of framing moisture
Why a Crew That Already Works in This Area Matters
A contractor who mainly builds in a drier climate and treats Burlington as just another job site will often skip the flashing, hardware, and drainage details this region actually requires — not out of carelessness, but because it's not what they're used to building for. A crew that regularly works Skagit County homes already knows how the rain moves, how the moss season behaves, and which details can't be shortcut here. That familiarity shows up in the parts of the deck you don't see once it's finished — the flashing, the footings, the fastener choices — which are exactly the parts that determine whether you're looking at a 15-year deck or a 30-year one.
