How long does a typical deck replacement take from permit to finished project?

Once permitted, most residential deck replacements take anywhere from a few days to two weeks depending on size, material, and weather. Permitting itself can add a few weeks depending on the local building department's current review times. We'll give you a realistic timeline once we've seen the site and scope.

What should I ask a contractor before hiring them for a deck replacement?

Ask whether they pull permits as standard practice, what fastener and hardware standards they use, and whether they'll inspect the ledger and footings rather than just replacing decking on top of an old frame. Ask for references from other deck projects in the area and confirm they carry proper licensing and insurance. A contractor who's vague about any of these is worth a second look before you sign anything.

What's the real difference between composite decking and capped PVC decking?

Composite decking is typically a wood-fiber and plastic blend, while capped PVC is fully synthetic with a protective outer layer. PVC generally handles moisture and moss better and holds up marginally better in shaded, damp spots, but it usually costs more than composite. Both outperform untreated wood on maintenance, and the right choice often comes down to budget and how much sun your deck gets.

Do all composite decking brands perform the same in wet, mossy conditions?

No — boards vary by brand in surface texture, cap thickness, and how well they resist algae and moss staining in shaded areas. Deeply grooved or heavily textured boards tend to hold moisture and organic growth longer than smoother, capped profiles. We'll point out which options make sense for the specific sun exposure your deck gets rather than recommend one product across the board.

Does Alger's proximity to the water actually make a measurable difference for decks compared to more inland homes?

Yes — the combination of salt-laden air and consistently damp conditions accelerates hardware corrosion and encourages moss growth faster than a similar deck built further inland would experience. It doesn't mean a deck can't last for decades here, but it does mean material and hardware choices matter more than they would in a drier location. That's a big part of why we build differently for this area than we would for an inland job.

Decks in Alger Take a Beating That Inland Decks Never See

If you've owned a deck out here for more than a few years, you already know it doesn't age like a deck in a drier, inland town. Alger sits close enough to the water that salt-laden air reaches every board, every fastener, and every piece of hardware holding the structure together. Add in the driving rain that comes sideways off winter storms, plus a shoulder season where tree cover and damp air turn every shaded deck surface into a moss farm, and you've got a structure that's fighting three different kinds of wear at once.

Most decks don't fail because the boards look bad. They fail underneath — ledger connections that have been wicking moisture for a decade, joist hangers rusting from the inside out, footings that were never sized for our saturated soil to begin with. By the time the surface looks rough, the frame underneath has often already been compromised for years. That's the gap a proper deck replacement is meant to close, and it's why doing it right here looks a little different than doing it right somewhere with a milder, drier climate.

Why Salt Air, Rain, and Moss Change the Job

Salt Air and Corrosion

Coastal-influenced air accelerates corrosion on any metal that isn't rated for it — nails, screws, joist hangers, post bases, even the fasteners holding railing brackets in place. Standard galvanized hardware can start showing rust streaks and pitting well before a wood deck's boards are due for replacement. Once a fastener corrodes, it loses holding strength long before it visibly fails, which is part of why we don't treat hardware selection as an afterthought on any Alger project.

Driving Rain and Water Management

Rain that comes in at an angle, rather than straight down, finds its way into gaps that would stay dry elsewhere — ledger-to-house connections, stair stringers, the underside of rim joists. Flashing detail and drainage slope matter more here than they would in a climate with gentler, more vertical rainfall. A deck built without proper flashing behind the ledger board is one of the most common failure points we find on tear-outs, and it's almost always invisible from the surface until the rot has already spread.

Moss Season

Shaded, north-facing, or tree-covered decks in this area go through a long stretch every year where moss and algae can establish themselves faster than most homeowners expect. Beyond the slip hazard, moss holds moisture against the decking surface, which shortens the life of wood boards and can stain or etch some composite and PVC products if left unaddressed. Material choice and board spacing both affect how much of a moss problem a deck will have five years down the road.

Signs It's Replacement Time, Not Repair Time

Not every tired-looking deck needs to be torn out. But there are signs that point past patching and toward a full replacement:

Soft or spongy spots in the decking, especially near the house or around posts
Rust staining bleeding out from fasteners or hardware
A ledger board that's visibly separating from the house, or siding damage right above it
Posts or footings that have shifted, tilted, or sunk into wet ground
Persistent moss or algae that keeps coming back within weeks of cleaning
Railings that flex or feel loose when pushed, which is a safety issue, not a cosmetic one
A deck that's more than 15-20 years old and was built before current fastener and flashing standards were common practice

If you're only seeing weathered boards and nothing structural, resurfacing or targeted repair may be the honest answer. We'll tell you that directly rather than push a full rebuild you don't need.

What a Correct Deck Replacement Actually Involves

A deck replacement done right starts underground and works its way up — not the other way around.

Footings and Framing

Footings need to be sized and set below frost depth and rated for our wet soil conditions, not just poured to whatever the old footprint used. Undersized or shallow footings are one of the most common shortcuts we find on older decks, and they're invisible until the structure starts to shift.

Ledger Attachment and Flashing

Where the deck ties into the house is the single most important detail on the entire structure. Correct flashing — installed in the right order relative to the house's water-resistive barrier and siding — keeps driving rain from working its way behind the ledger and into the framing of the house itself. This is not a place to save money.

Fasteners and Hardware

Given the salt air here, we spec corrosion-resistant fasteners and connectors rated for the decking material and coastal exposure, not whatever's cheapest at the yard. This is a small percentage of total project cost and one of the biggest factors in how long the frame lasts.

Drainage and Slope

Decking should be sloped slightly away from the house and gapped correctly so water sheds instead of pooling. Poor drainage is a direct contributor to both rot and moss buildup.

Railings and Guardrails

Railings need to meet current height and spacing requirements and be attached to solid blocking, not just toe-screwed into decking boards. This matters for safety and for passing inspection.

Choosing the Right Decking Material for This Climate

There's no single "best" decking material — there's a best material for your budget, your maintenance appetite, and how much sun or shade your deck gets. Here's how the common options actually perform under Alger conditions:

Material	Salt Air / Corrosion	Moss & Algae Resistance	Maintenance
Pressure-treated wood	Good with rated fasteners	Needs regular cleaning/sealing	Highest — annual cleaning, periodic sealing
Cedar	Good with rated fasteners	Moderate — natural oils help some	High — regular sealing to hold color and resist moisture
Composite decking	Excellent	Good, varies by brand/finish	Low — periodic washing
PVC/capped polymer	Excellent	Very good	Lowest — occasional washing

Wood decks can absolutely work here, but they demand more of the homeowner's time and attention over the years. Composite and PVC products cost more up front but shed water and resist moss buildup with far less upkeep, which is a real consideration on a shaded lot or a deck that doesn't get much direct sun to dry out between rain events. We'll walk through the honest trade-offs for your specific site rather than push one product line.

Our Deck Replacement Process

On-site assessment. We inspect the existing structure, ledger, footings, and framing to determine what's driving the failure and whether replacement is actually the right call.
Design and material selection. We go over decking, railing, and hardware options based on your budget, sun/shade exposure, and how much maintenance you actually want to do.
Permitting. We handle the permit application and coordinate any required inspections through the local building department.
Demolition. Full removal of the old deck, including checking for any hidden rot or damage to the house structure behind the ledger.
Framing and flashing. Footings, posts, beams, joists, and ledger flashing are installed to current code, with corrosion-rated hardware throughout.
Decking and railing installation. Boards, fascia, and railings go in with correct spacing and slope for drainage.
Final walkthrough. We review the finished deck with you, cover basic care for your chosen material, and close out the permit inspection.

Permits and Code Considerations

Most deck replacements in this area require a building permit, particularly when the deck is attached to the house or elevated above a certain height. Permits exist for a good reason here — they're what catch undersized footings, missing ledger flashing, and railing shortcuts before they become someone's problem years later. We pull permits as a standard part of the job rather than treating it as optional, and we coordinate inspections so there's no guesswork on your end about whether the work will pass.

What Deck Replacement Costs Depend On

We won't quote a number without seeing the site, but these are the factors that move the price up or down on most projects:

Factor	Why It Matters
Deck size and shape	More square footage and complex angles mean more material and labor
Decking material chosen	Composite and PVC cost more upfront than wood but need less upkeep over time
Height and access	Elevated decks or stairs add framing, railing, and safety requirements
Existing structural damage	Rot found at ledger or footings during demo can add scope once uncovered
Railing style	Cable, glass, and custom railing systems cost more than standard baluster rail
Site access	Difficult access for equipment or material delivery can affect labor time

Deck Maintenance That Actually Extends Its Life

Whatever material you choose, a few habits make a real difference in how long a new deck holds up in this climate:

Clean moss and algae off the surface at least once a year, before it gets a foothold
Keep gutters and downspouts near the deck clear so runoff isn't dumping extra water onto it
Check railing connections annually for looseness, especially after winter storms
Trim back overhanging branches to let more sun and airflow reach shaded sections
For wood decks, plan on resealing on the schedule your product calls for — skipping it shortens the deck's life considerably
Watch for rust staining around fasteners, which is an early sign hardware needs attention

Why It Matters That We Already Work in Alger

A crew that only occasionally works this stretch of Whatcom County will spec a deck the same way they would anywhere else. A crew that works here regularly knows the ledger flashing detail that keeps water out during a real driving rain, specs hardware that's actually going to hold up to salt air over the long haul, and understands why a shaded deck here needs different board spacing than one that sits in full sun all day. We've built our process around the conditions this area actually produces, not a generic checklist, and that shows up in how long the work lasts rather than just how it looks on day one.
