Why Burlington Decks Wear Out Faster Than the Rest of the House
A deck takes a different kind of beating than siding or roofing. It sits low, close to grade, exposed on the underside as well as the top, and it holds moisture longer than any other structure on the property. In Burlington, that exposure is compounded by our stretch of the Skagit Valley: damp air moving in off the Salish Sea, a long stretch of the year where surfaces stay wet, and shaded, low-lying yards where moss and algae never fully dry out between rains. Add in the salt-laden air common to Skagit County's lowlands, and you get a slow, steady breakdown of fasteners, ledger boards, and framing that isn't always visible until you start pulling boards up.
Most decks we're asked to replace in this area aren't failing because the homeowner neglected them. They're failing because the deck was built to a generic spec that didn't account for how much water this region actually holds onto through fall, winter, and spring.

Signs a Burlington Deck Needs Replacement, Not Just Repair
Repair makes sense when the problem is isolated — a cracked board, a loose railing baluster, surface graying. Replacement becomes the honest recommendation when the problems are structural or systemic. Some of what we look for:
- Soft or spongy decking when you walk across it, especially near the house or in shaded corners
- Rot or discoloration at the ledger board — where the deck attaches to the house — which is the single most common failure point we see
- Rust streaking or corroded fastener heads, a sign the hardware is breaking down faster than the wood around it
- Persistent green or black growth that comes back within weeks of cleaning, meaning moisture is trapped rather than shedding
- Posts or footings that have shifted, settled, or show cracking at the base
- A deck older than 15–20 years built with older fastening methods or undersized framing by today's code
If two or more of these show up, patch repairs usually just delay the same conversation a year or two down the road, often after the damage has spread further into the framing.
What's Usually Hiding Underneath
Because Burlington's moisture cycle is long, the surface boards often look worse than the frame — or the opposite: attractive decking sitting on a compromised structure. We don't quote a replacement without pulling boards and inspecting the ledger, joists, and footings directly. A deck that looks fine from the yard can still have a ledger board that's been wicking water for years.
Choosing a Decking Material for This Climate
There's no single "best" decking material — there's a best fit for how much maintenance you want to do and how much moss tolerance you're willing to live with. Here's how the common options actually perform in a wet, moss-prone environment like ours:
| Material | Moisture Behavior | Moss/Algae Tendency | Maintenance |
|---|---|---|---|
| Pressure-treated wood | Resists rot if properly sealed; end grain and fastener holes remain vulnerable | Prone to moss in shaded areas without regular cleaning | Annual cleaning and resealing recommended |
| Cedar | Naturally rot-resistant heartwood, but softer and more porous than composite | Moderate; grays and can host growth without upkeep | Periodic cleaning and oiling for appearance and longevity |
| Composite decking | Doesn't absorb water the way wood does; core materials vary by brand | Can still develop surface film in shaded, damp spots — less than wood, not immune | Occasional washing; no sealing or staining |
| PVC/capped polymer | Fully sealed surface, minimal water uptake | Lowest tendency of the group, but still needs washing in persistently shaded areas | Lowest ongoing maintenance |
We install all of these depending on the homeowner's budget and priorities. What we won't do is install any decking material — wood or composite — without correcting the moisture management underneath it first. A better board on a poorly flashed frame just delays the next failure; it doesn't prevent it.
What a Correct Deck Replacement Actually Involves
Ledger and Flashing
The ledger board attachment is where most deck failures start, and it's the part most likely to be done wrong on an older or lower-bid build. A correct install uses proper flashing to keep water from running behind the ledger and into the house's rim joist — a detail that matters more here than in drier climates, since Burlington's rain events are frequent enough that any gap gets tested repeatedly over a wet season.
Footings and Framing
We check footing depth and condition rather than assuming the existing footings are adequate. Framing gets sized to current code span tables, not just matched to whatever was there before — older decks are frequently under-built by today's standards, especially around stair stringers and beam spans.
Fastening and Board Layout
Fastener choice matters as much as the decking material itself. Corrosion-resistant hardware rated for the specific decking product is non-negotiable in a region with salt-influenced air; mismatched or bargain fasteners are one of the fastest ways to reintroduce rust staining and structural weakness within a few seasons.
Railings and Code Compliance
Railing height, baluster spacing, and guard requirements are governed by code, not preference. Replacement is the right time to bring an older deck's railings up to current standards if they aren't already compliant.
Our Deck Replacement Process
Homeowners in Burlington generally go through the same four stages with us, and we walk through each one before work starts so there are no surprises mid-project:
- On-site assessment — we inspect the ledger, framing, and footings directly, not just the visible decking, and explain what we find in plain terms.
- Scope and material selection — we go over decking material options, fastening systems, and railing needs against your budget, with an honest read on trade-offs rather than a sales pitch toward the most expensive option.
- Permitting — deck replacements of most sizes require a permit; we handle that process so it isn't left to the homeowner to navigate.
- Demolition and rebuild — old decking and, where needed, framing come out; new structure goes in with correct flashing, footings, and fastening before decking and railings are installed.
We finish with a walkthrough so you can see the flashing, framing, and fastener details before decking covers them up — the parts of the job that matter most for how long the deck lasts are also the parts you'll never see again once it's finished.
Cost Factors for Deck Replacement
Every deck is different, so exact pricing depends on the specifics, but the main variables that move the number are consistent:
| Factor | Why It Matters |
|---|---|
| Deck size and shape | Square footage and complexity of the layout (multi-level, curves, built-in seating) directly affect labor and material |
| Decking material | Pressure-treated wood is the lowest upfront cost; composite and PVC cost more up front but less in ongoing maintenance |
| Framing and footing condition | If the substructure needs to be rebuilt rather than reused, that adds labor and material beyond surface decking |
| Railing style | Basic code-compliant railing costs less than cable, glass, or custom designs |
| Height and access | Elevated decks or decks with difficult site access require more structural work and time |
We give a written, itemized estimate before any work begins — not a rough verbal number — so you know what you're paying for and why.
Keeping a New Deck Ahead of the Moss
Even the best-built deck in Skagit County will face the same conditions the old one did. A few habits go a long way toward protecting the investment:
- Sweep debris and standing leaves off the surface regularly, especially in shaded corners where moisture lingers
- Keep gutters and downspouts clear so runoff isn't draining directly onto or under the deck
- Trim back vegetation that shades the deck and slows drying time after rain
- Wash the surface at least once a year to interrupt moss and algae before it establishes
- Re-seal wood decking on the schedule appropriate to the product — don't wait until it's visibly graying
Why Local Experience Matters for This Job
A crew that only occasionally works in this region can still build a technically sound deck on paper. What local experience adds is knowing where water actually collects on Burlington properties, which shaded yard layouts turn into moss traps within a season, and how much margin to build into flashing and fastener choices given how long our wet season really runs. We've seen what generic specs do to decks here over five, ten, fifteen years, and we build accordingly rather than defaulting to whatever gets a project through inspection with the least effort.
