Decks — Structure & Materials

It Starts Underground.
Everything Else Is Decorating.

Here's something the deck brochures don't tell you: the part of your deck that determines whether it lasts twenty years or seven is the part you will never see. It's underground. It's in the footings, the ledger connection, the post bases, and the framing hardware. The composite surface that makes your neighbors envious is incidental. The structure is the deck.

In the Pacific Northwest — where Seattle and Bellevue homeowners deal with persistent moisture and a wet climate that makes organic materials feel personally targeted — the structural decisions are everything. Washington State requires a 60 psf live load for residential decks, 50% higher than the national standard. That's not bureaucratic enthusiasm. That's the state saying your deck will have people on it, furniture on it, snow on it, and it needs to handle all of that without complaint.

The 5 Structural Elements That Separate the 10-Year Deck from the 30-Year Deck

  • 01
    The Ledger Connection. The board that attaches your deck to the house. Without proper flashing, water wicks between the ledger and the house framing and the rot that follows is invisible until it's structural. In Seattle's rain, this isn't a formality — it's the detail that determines whether the connection holds for decades or fails quietly behind the siding.
  • 02
    Post Footings. Everything above grade is only as stable as what's below it. Posts set in soil without concrete footings shift with seasonal moisture changes. Movement in a deck compounds rather than stabilizes over time.
  • 03
    Beam Sizing and Span. Undersized beams deflect under load in ways that feel wrong underfoot and stress every connection above and below them. Beam sizing is a structural calculation — not a judgment call made by eye on the job site.
  • 04
    Joist Hangers and Hardware. In the Pacific Northwest, that means hot-dipped galvanized or stainless steel throughout. Standard zinc-plated hardware corrodes in high-moisture environments and loses its rated load capacity as corrosion advances.
  • 05
    Decking Fastening and Spacing. Boards need spacing to shed water. Hidden fastener systems that grip from the board's edge eliminate the splitting and corrosion points that surface screws create over time.

Tommy builds from the ground up because that's the only direction that matters structurally. Get these five elements right and the deck takes care of itself for decades. Get any one of them wrong and the surface is irrelevant.


Decking Materials

Every Material Comes With
a Different Long-Term Commitment.

The maintenance conversation should happen before the deck is built, not after. This is especially true in Seattle, where roughly 150 days of rain a year means your decking is enrolled in a 12-month moisture endurance program whether you like it or not.

Pressure-Treated Wood
Most demanding. Clean, dry, and seal every 1–2 years without exception. In Seattle's wet climate, pressure-treated deteriorates faster than most homeowners expect when maintenance lapses.
Cedar & Redwood
Naturally resistant, still needs work. Annual cleaning and periodic sealing. More dimensionally stable than treated pine but not maintenance-free in a Pacific Northwest climate.
Composite — Trex / TimberTech / Fiberon
Low maintenance, higher upfront. Annual cleaning only — no sealing, no staining. In a high-moisture environment with constant organic debris, composite's resistance to both is a genuine advantage.
Aluminum Decking
Zero maintenance. Doesn't rot, doesn't fade, doesn't require sealing. Handles Pacific Northwest moisture without complaint. Tradeoff: harder underfoot and a more industrial aesthetic.

Trex — the category-defining brand, 95% recycled materials, 25-year warranty on most lines. Excellent fade and stain resistance. Reliable in Seattle's freeze-thaw cycles.

TimberTech Azek — PVC rather than wood composite. Zero wood fiber content means essentially zero moisture absorption in 150-days-of-rain Seattle. 50-year warranty on premium lines. Double what most competitors provide.

Fiberon — competes on value. Solid performance, good warranty coverage, lower entry price. For budget-conscious projects where composite is the right call but the premium lines aren't justified.

Deck Design & Layout

The 3 Biggest Mistakes Homeowners Make
Before a Single Board Goes Down.

  • 01
    Underestimating traffic flow. Homeowners design for how the deck looks on paper. They don't design for how twelve people move through it on a Saturday afternoon. Doors swing into the space. The grill ends up in the wrong corner. Traffic flow has to be designed in from the beginning — not discovered after the build.
  • 02
    Getting railing height and spacing wrong. In Washington State, decks 30 inches or more above grade require a minimum 36-inch guardrail. Balusters cannot be spaced more than 4 inches apart. These are code requirements, not design preferences. An out-of-code railing has to be rebuilt at full cost.
  • 03
    Ignoring water management. In the Pacific Northwest this one is particularly punishing. A deck designed without attention to drainage, slope, and moisture management will trap water against the house, rot the ledger board, and potentially compromise the structure it's attached to. Water ignored in the design phase becomes a structural problem in year three.

5 Modern Architectural Layouts — Which One Is Your Lot Asking For?

Layout 01

Single-Level Floating Deck

Low to grade, reads as a seamless extension of the landscape. Works best on flat lots. Clean, modern, no height differential between deck and yard.

Layout 02

Multi-Level Cascade

The answer for sloped lots — common throughout Seattle's hillside neighborhoods and the Eastside. The grade change becomes a design feature, not an obstacle.

Layout 03

L-Shape Wrap

Wraps around two sides of the house, distinct zones without physical separation. Effective on corner lots or homes where two exposures are both worth activating.

Layout 04

Courtyard Deck

Turns inward toward a central feature — fire pit, water element, kitchen island. Creates intimacy that open-facing decks can't achieve. Works well on urban Seattle lots.

Layout 05

Indoor-Outdoor Transition

Defined by its connection to the house. Wide sliding or folding glass doors erase the boundary. Requires a cover in the Pacific Northwest — with one, the most livable configuration available.

Water-Facing

Classic Water-View Design

Cable or glass railing only — anything else competes with the view you bought the property for. Size the deck to the view. Marine-grade hardware throughout.


Why Seattle Decks Need a Cover

An Uncovered Deck in Seattle Is a Good Idea
for About Six Weeks a Year.

The other forty-six weeks it's either wet, threatening to be wet, or recovering from being wet. A covered deck in Seattle gets used in October. It gets used in February. It gets used on the kind of gray drizzling Tuesday afternoon that describes roughly half the calendar year in the Puget Sound region. The cover is what transforms a deck from a seasonal amenity into a genuine outdoor room.

The second argument is structural. Rain is the primary enemy of every deck built in the Pacific Northwest. A cover dramatically extends the life of the decking material, the railing system, and the furniture on it. The third argument is the ledger — the point where the deck connects to the house is the most vulnerable detail in any attached deck. Constant rain exposure without cover accelerates moisture intrusion at exactly the place where failure has structural consequences for the house itself.

"A covered deck in Seattle isn't an upgrade. It's the baseline design decision that makes everything else worth building." Tommy builds covers that look like they were always supposed to be there.


Top 5 Modern Railing Designs

The Railing Is the Detail That
Makes or Breaks the Deck.

  • 01
    Cable Railing. Horizontal stainless steel cables tensioned between posts — the defining look of contemporary outdoor design. The cables nearly disappear visually, preserving sightlines to the yard, the water, or the treeline beyond. In Seattle where views and landscape are part of the point, cable railing is the single best way to have a railing without feeling like you have a railing.
  • 02
    Glass Panel Railing. Tempered glass panels in aluminum or steel frames — unobstructed views, clean architectural finish. Reads as genuinely upscale. Minimal maintenance — occasional cleaning keeps it sharp indefinitely.
  • 03
    Black Steel with Wood Cap Rail. Powder-coated black steel balusters paired with a natural wood cap rail. The industrial-meets-warm aesthetic that dominates current design. Works equally well on modern farmhouses, contemporary builds, and Craftsman-style homes throughout Seattle.
  • 04
    Horizontal Wood Slat Railing. Wide horizontal slats at consistent spacing create a privacy screen effect while maintaining a modern profile. Cedar and composite hold up well in the Pacific Northwest and the horizontal lines complement low-profile deck designs naturally.
  • 05
    Composite Railing Systems. The look of painted wood with none of the maintenance — no rot, no repainting, no warping. For homeowners who want clean lines and zero upkeep, composite systems are the practical answer that still delivers real visual impact.

Style Inspirations

What History Got Right That Current Trends
Are Just Rediscovering.

Classic New England — Restraint as Design

White painted rail and baluster against natural or stained decking, dark hardware, proportions that carry the whole aesthetic. New England architecture has been building outdoor structures in a punishing wet climate for four hundred years. The design language that emerged isn't decorative — it's functional architecture that happens to look beautiful because every element earns its place. The climatic parallel between coastal New England and the Pacific Northwest is closer than most people realize. Classic never goes out of style — and in a climate that tests everything, classic usually outlasts clever.

Traditional Japanese — The Meaningful Use of Space

Japanese design is organized around ma — the meaningful use of negative space. What is left out is as considered as what is put in. In outdoor design, Japanese influence shows up as clean horizontal lines, natural materials left close to their original state, water features that move slowly, and planting that creates enclosure without density. In a world that's loud and fast and visually relentless, this is solving for stillness. Traditional Japanese design was doing that centuries before stillness became scarce.

California Outdoor Living — The Commitment Worth Stealing

California didn't invent outdoor living. It just never stopped doing it. The lesson isn't the sunshine — that's non-transferable. The lesson is the commitment: outdoor living as a design priority rather than a secondary consideration. Cover the space, wire it properly, build the kitchen, add the heat source, and treat it like a room. The Pacific Northwest homeowner who makes that commitment gets a space that works year-round.


Outdoor Living

The Outdoor Kitchen, the Wrap-Around Porch,
and the Car That's Worth Protecting.

Outdoor Kitchen Design in the Pacific Northwest

Outdoor kitchens in the Pacific Northwest require a different conversation than what you'd have in Phoenix. The climate is the variable that determines everything. The first consideration is cover. A pergola with a solid panel system, a lean-to off the house, or a full gable structure is not optional here — without it you're designing a very expensive object to get rained on. Material selection follows: stainless steel, concrete countertops, and marine-grade cabinetry that handle moisture without warping or delaminating. Built right, an outdoor kitchen in the Pacific Northwest becomes the best room in the house.

The Southern Wrap-Around Porch — Why Seattle Should Steal This Idea

A full wrap-around porch does something no amount of insulation or window film can replicate: it keeps rain off the walls entirely. In the American South this was survival architecture. The porch was the air conditioner before air conditioning existed. The Pacific Northwest doesn't have the South's heat problem — but it has the South's rain problem, and then some. A wrap-around porch in the Pacific Northwest isn't a place to sit in the heat — it's a place to sit in the rain, which is nine months of the year.

Covered Parking — Protecting Your Second Biggest Investment

A car parked outside in the Pacific Northwest is taking a beating every single day. Rain, UV, tree sap, temperature swings causing condensation inside door panels and wheel wells. A vehicle kept under cover consistently holds its value better than one left exposed. Paint condition is one of the first things a buyer evaluates — and paint shielded from the elements for five years looks dramatically better than paint that hasn't been. That difference can be measured in thousands of dollars at trade-in.


Fencing

The Most Honest Built Object
on Any Property Is the Fence.

No design brief. No aesthetic committee. No conversation about finish options or hardware vocabulary. The fence goes up because something needs to stay in or stay out, and it needs to do that reliably for as long as possible with as little attention as possible. That's the entire specification. And the result — when a fence is built with that philosophy — is a permanent, proportional, resolved object that outlasts every trend that came before and after it.

Top 5 Modern Non-Wood Fence Materials

  • 01
    Vinyl (PVC) Fencing. The most direct wood replacement in terms of appearance. Won't rot, won't need painting, handles moisture without complaint. In the Pacific Northwest's temperate climate, vinyl is a legitimate low-maintenance choice for traditional fence profiles.
  • 02
    Aluminum Fencing. Powder-coated aluminum — same clean lines as ornamental iron, none of the rust. Virtually maintenance-free. Particularly well suited to pool enclosures and property perimeters where visibility through the fence is part of the design intent.
  • 03
    Steel and Corten Steel. Black steel horizontal slat fencing is the most sophisticated non-wood option for contemporary architectural styles. Corten develops a stable rust patina rather than deteriorating — adds warmth and texture while requiring zero maintenance. In the Pacific Northwest's moist climate, Corten develops its characteristic warm color quickly and holds it indefinitely.
  • 04
    Composite Fencing. The same technology that transformed decking. Resists moisture, won't rot or split, holds color without painting. For homeowners who want the warmth of wood appearance with composite's moisture resistance, this is the most direct solution.
  • 05
    Concrete Block and CMU. Delivers permanence and sound attenuation that no other fencing material approaches. Doesn't move, doesn't rot, doesn't fade. For privacy walls in urban settings where longevity and acoustic performance matter, concrete is the honest answer.

The White Picket Fence — Still Relevant, Always Will Be

Drive through the established neighborhoods of Seattle — the Fremont bungalows and Ballard Craftsmans, the Victorian streetscapes of Capitol Hill — and the white picket fence is still there. Not as a symbol of suburban aspiration but as something quieter and more durable: a design element that works. Scaled correctly for the human body, proportioned to complement almost any residential architecture built in the last two centuries. Tommy still builds them. People still ask for them.

How Farmers Build Fence — And What Residential Fencing Gets Wrong

Post depth, soil condition, concrete footings — these are the decisions that determine whether the fence is standing in twenty years or leaning in five. Residential fencing too often gets designed from the street and built top-down: appearance first, structure second. The farmer's instinct is the opposite. Structure first. Always. Tommy builds residential fences with the farmer's logic underneath and the homeowner's aesthetic on top.

Frequently Asked Questions

Decks & Fencing — Straight Answers

The questions Tommy gets on every estimate call — answered before you have to ask them.

Composite decking — Trex, TimberTech, or Fiberon — is the most practical choice for Pacific Northwest conditions. It doesn't absorb water, won't rot, handles freeze-thaw cycles without cracking, and requires only annual cleaning. TimberTech's Azek line uses PVC with essentially zero moisture absorption in a climate that sees 150 days of rain a year.

Composite deck builds in the greater Seattle area typically run $40–$75 per square foot installed. A 300 square foot Trex deck with aluminum railings usually lands in the $14,000–$22,000 range. Tommy provides a written estimate before any work begins — no ranges, no surprises.

You don't need one — you just won't use an uncovered deck for roughly 46 weeks of the year. A covered deck gets used in October, February, and every drizzling Tuesday in between. The cover also protects the decking material, the railing, and the critical ledger connection from continuous moisture exposure.

Cable railing or glass panel systems. On a water-facing property, traditional wood balusters create a visual grid that interrupts the view — on a property where the view is the entire point, that's an architectural mistake that's expensive to correct after the fact. Both cable and glass meet code requirements while preserving sightlines completely.

  • Ledger connection with proper flashing — prevents moisture intrusion at the house attachment point
  • Post footings correctly sized and set for the load
  • Correctly sized beams for the span and anticipated load
  • Hot-dipped galvanized or stainless steel hardware throughout
  • Proper decking fastening and board spacing for water drainage

1. Underestimating traffic flow — designing for how the deck looks on paper rather than how people actually move through it. 2. Getting railing height and spacing wrong — code requirements in Washington State are not negotiable. 3. Ignoring water management — water ignored in design becomes a structural problem by year three.

A properly installed composite deck lasts 25 to 50 years. TimberTech carries a 50-year warranty on premium lines, Trex's Transcend carries 25 years. Pressure-treated wood decks in the Pacific Northwest typically last 10 to 15 years before significant maintenance or replacement is needed.

For pure low maintenance, aluminum or vinyl — neither rots, fades, or requires painting. For sophisticated aesthetics, powder-coated steel or Corten steel deliver architectural quality with essentially zero ongoing maintenance. Corten develops its warm rust patina in Seattle's moist climate quickly and holds it permanently.

Both will dramatically outperform pressure-treated wood. Trex leads on environmental credentials — 95% recycled materials, 25-year warranty. TimberTech's Azek line uses PVC with zero wood fiber content and essentially zero moisture absorption, plus a 50-year warranty on premium lines. For a climate with 150 days of rain, TimberTech's moisture spec is a meaningful differentiator. Tommy works with both.

The multi-level cascade is the best answer for sloped lots — common throughout Seattle's hillside neighborhoods and the Eastside. Each level serves a distinct zone and the grade change becomes a design feature rather than an obstacle. Tommy has built multi-level cascades on steep Kirkland and Queen Anne hillsides where the grade challenge became the best feature of the final design.

Tommy serves the greater Seattle and Eastside area including Fremont, Ballard, Queen Anne, Magnolia, Capitol Hill, Shoreline, Lake Forest Park, Bothell, Kenmore, Bellevue, Kirkland, Medina, Clyde Hill, Mercer Island, and surrounding communities throughout King and Snohomish County. Call or text (206) 614-0001.

Yes — and this is one of the genuine advantages of working with a single contractor who does the full scope. Coordinating deck and fence work through Tommy means consistent design language, one schedule, one point of contact, and no handoff gaps between contractors that result in mismatched details or scheduling delays.
