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

Most residential deck replacements take one to two weeks once permits are approved, depending on the deck's size and complexity. Weather can add delays during the wetter months, since framing and flashing work needs reasonably dry conditions to be done properly. Permit approval timelines vary and are worth factoring into your planning separately from the actual construction time.

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

Ask whether they pull the permit themselves, how they detail the ledger board flashing, and whether they carry proper licensing and insurance. Ask to walk through their process for inspecting the framing before it's covered back up, since that's the step most often rushed. A contractor who answers these clearly and specifically, rather than vaguely, is usually the safer bet.

Is composite decking actually worth the extra cost over wood?

It depends on how much maintenance you're willing to do. Composite costs more upfront but skips the annual staining and sealing that wood needs, which matters in a climate where wood decks demand regular upkeep to fight moss and graying. Wood is a legitimate choice too if you don't mind the maintenance schedule and want the lower initial cost.

What's a hidden fastener system, and do I need one?

Hidden fastener systems clip decking boards from the sides instead of screwing through the top face, giving a cleaner look with no visible screw heads. They typically cost more in materials and labor than face-screwing but are compatible with most composite and PVC boards. It's a preference call more than a necessity — both methods hold up structurally when installed correctly.

Does the City of Redmond require a permit to replace a deck?

In most cases, yes — deck replacement involving the ledger connection, framing, or guardrails typically requires a permit and inspection. Requirements can vary based on the deck's size, height, and attachment method, so it's worth confirming specifics for your property rather than assuming. We handle the permit process as part of the job so you don't have to navigate it yourself.

Redmond Decks Take More Punishment Than They Look Like They Do

Redmond sits inland from Puget Sound, so homes here aren't dealing with salt spray the way waterfront properties closer to the Sound are. But that doesn't mean local decks get an easy ride. King County's long wet season, heavy tree canopy in many Redmond neighborhoods, and months of low sun angle add up to a different kind of punishment: constant moisture, slow drying, and moss that doesn't quit from fall through spring.

A deck that looks fine from the yard can be hiding soft framing underneath. Water doesn't need a storm to do damage — it just needs time, and in this climate, time is the one thing it always has. That's the difference between a deck that needs a few boards swapped and one that needs a full replacement.

Repair or Replace? How to Tell

Not every tired-looking deck needs to come out. But a few signs point toward replacement rather than patching:

Soft or spongy spots when you walk across the decking, especially near the house
Visible rot, dark staining, or crumbling wood at the ledger board where the deck meets the house
Persistent moss or green film on boards that comes back within weeks of cleaning
Rust streaks around fasteners, or screws that spin freely without biting
Railings or posts that flex noticeably when leaned on
A deck older than 20 years that has never had the framing inspected
Multiple past repairs to the same section — a sign the underlying cause was never fixed

If it's just surface graying or a few loose boards, a repair or refinish might be all that's needed. Once the framing or ledger connection is compromised, patching individual boards just delays a bigger problem — and in the meantime, it's a safety issue, not a cosmetic one.

What a Correct Deck Replacement Actually Involves

It Starts Underneath, Not on Top

The visible decking is the easiest part to get right. The parts that actually determine whether a deck lasts are the ones you don't see once it's finished: the ledger board connection, the joists, the posts, and the footings. Any deck replacement worth doing starts with a full teardown and inspection of that structure — not just a new surface laid over old bones.

The Ledger Board Is Where Most Failures Start

The ledger board — the piece that bolts the deck to the house — is the single most common failure point in this climate. Without proper flashing, water works its way behind the ledger and into the house's band joist and framing, where it can sit and rot quietly for years. A correct replacement includes a properly flashed ledger connection: flashing that sheds water away from the house, not one that just gets caulked and hoped for.

Framing and Fasteners

Joists and beams need to be sized correctly for the span and load, set with proper spacing, and connected with corrosion-resistant hardware. In a wet climate, standard fasteners corrode faster than most homeowners expect — hot-dip galvanized or stainless steel hardware, rated to match whatever lumber is used (especially modern treated lumber, which is more corrosive to metal than older formulations), is the standard we hold ourselves to.

Footings

Posts need to bear on footings that are sized and set to the depth local code requires, on solid ground — not just poured against loose fill. This is one of the areas where cutting corners doesn't show up until years later, when a post starts to settle or heave.

Choosing a Decking Material

There's no single "right" decking material for every Redmond home — it depends on budget, how much maintenance you want to do, and how the deck gets used. Here's how the common options actually compare, without the marketing spin:

Material	Upfront Cost	Maintenance	How It Handles This Climate
Pressure-treated wood	Lowest	Annual cleaning, periodic staining/sealing	Prone to moss growth and graying without regular upkeep; needs the sealant reapplied more often here than in drier regions
Cedar	Moderate	Regular cleaning and refinishing	Naturally more rot-resistant than treated pine, but still needs maintenance to fight moss and UV graying
Composite decking	Higher	Occasional washing, no staining/sealing	Resists rot and doesn't need refinishing, but can still grow surface mold or moss film in shaded, damp spots if not rinsed periodically
PVC/capped polymer	Highest	Occasional washing	Fully sheds water and resists staining and mold better than composite in consistently shaded areas, at a higher material cost

We install all of these. Our job is to lay out the honest trade-offs — maintenance burden, moisture behavior, upfront versus long-term cost — so you pick based on how you'll actually use and maintain the deck, not based on which one has the flashiest sample board.

Permits and Code Requirements

Deck replacement in Redmond typically requires a permit, especially when the ledger connection, framing, or guardrails are involved — which is nearly always the case in a full replacement. Permit requirements cover things homeowners rarely think about until an inspector flags them: guardrail height and baluster spacing, stair rise and run consistency, and proper structural attachment to the house.

Skipping the permit might save a little time upfront, but it creates real problems later — at resale, at insurance claim time, or if a future inspector asks to see it. We pull permits as part of the job and build to what the inspector will actually check, not just to what looks finished.

Our Deck Replacement Process

On-site assessment — we inspect the existing deck, ledger, and framing to confirm whether replacement (versus repair) is the right call, and identify any hidden rot before work starts.
Permit and planning — we handle the permit application and confirm the layout, material choice, and railing style with you before demolition begins.
Teardown — full removal of the old deck, including decking, framing, and the ledger connection, with the house's band joist checked for hidden damage once it's exposed.
Structural repair — any rotted framing, sheathing, or band joist material found during teardown gets repaired before rebuilding continues, not built over.
Ledger flashing and reattachment — the ledger is reinstalled with proper flashing to direct water away from the house, a step that's easy to shortcut and expensive to fix later.
Framing and footings — joists, beams, and posts are set to code with corrosion-resistant hardware, footings poured or confirmed to proper depth.
Decking installation — boards installed with correct spacing for drainage and seasonal movement, using the fastening method suited to the material.
Railings and stairs — built to code height and spacing requirements, with attention to how they'll hold up to years of wet-weather use.
Final inspection and walkthrough — we schedule the city inspection and walk the finished deck with you before calling the job done.

Railings, Stairs, and Everyday Safety

Railings and stairs get more wear than people expect — they're what everyone grabs, leans on, and steps on in the rain. In this climate, stair treads are one of the first places moss and algae take hold, since they get less sun and more foot-tracked moisture than open decking. We pay attention to tread spacing and surface texture during installation, and it's worth building a quick rinse of stairs and high-traffic spots into your regular deck cleaning, especially heading into the wetter months.

Living With a New Deck in This Climate

A correctly built deck still needs some upkeep — no material here is truly maintenance-free. Composite and PVC decking cut down the work substantially compared to wood, but gutters that drain onto or near the deck, overhanging trees, and shaded corners will still collect moisture and need an occasional rinse. Wood decks need a real maintenance schedule: cleaning, and staining or sealing on a cycle, not just when it starts looking bad. Whatever material you choose, we'll walk you through what upkeep actually looks like so the deck we build stays solid for years, not just for the first season.

Why It Matters to Hire a Crew That Already Works in Redmond

Deck replacement isn't a one-size-fits-all job, and a crew that only shows up in the area occasionally doesn't carry the same working knowledge as one that's dealt with Redmond's permitting process, soil conditions, and moisture patterns repeatedly. We know what local inspectors look for, how footings behave in this ground, and which details — like ledger flashing — actually matter here versus in a drier climate. That local track record is also what protects you after the job is done: a company that's established in this area has a reputation to stand behind, not just a truck that passed through.
