Cedar Deck Building
Handis cedar deck building puts western red cedar 5/4 by 6-inch decking on pressure-treated framing (or full-cedar framing on the upgrade builds) — installed with hot-dipped galvanized or stainless fasteners sized to cedar's chemistry, capped with cedar railing and trim, through-bolted Z-flashed ledger on attached builds per IRC, and stained and sealed on the first coat unless the homeowner asks for natural weathering — from $18,000 for a standard 200 to 300-square-foot build to $40,000 for a larger build with full cedar framing, cedar railing, cap rail, fascia, and stair detailing. Western red cedar is the traditional Pacific Northwest deck material. The grain is warm, the color new is honey-brown, and the surface weathers to a silver-gray patina if left unstained. Cedar accepts stain well — properly stained cedar holds its color through Pacific Northwest winters with biennial maintenance; cedar left raw weathers to silver in 12 to 18 months and stays that color for the deck's life. Cedar lasts 15 to 30 years on a residential deck in the Puget Sound depending on the homeowner's commitment to the stain cycle and the fastener grade used at install.

What Does a Cedar Deck Build Include?
A cedar deck build is a full new-construction build with western red cedar decking — covering site staking and footing layout, concrete pier or helical pier footings, framing in pressure-treated (standard) or full cedar (upgrade option), through-bolted Z-flashed ledger on attached builds per IRC R507.9.1.3, western red cedar 5/4 by 6-inch decking install with stainless steel or hot-dipped galvanized deck screws sized for cedar, cedar 2x4 cap-rail and railing system (or aluminum baluster upgrade), cedar fascia at the rim joist, low-voltage stair lighting, the first coat of stain-and-sealer (or left raw for natural weathering at the homeowner's request), and final cleanup. Handis covers cedar builds from $18,000 for a standard 200 to 300-square-foot build up to $40,000 for a larger build with full cedar framing, cedar railing, cap rail, fascia, and stair detailing.
Western Red Cedar Decking — 5/4 by 6-Inch Standard
We install western red cedar 5/4 by 6-inch (full 1-inch by 5.5-inch dimensional) decking as the standard. Cedar 2x6 (full 1.5-inch by 5.5-inch dimensional) is an upgrade option for builds where the homeowner wants the heavier, more substantial board profile. Decking goes on with stainless steel or hot-dipped galvanized deck screws set flush — top-driven on cedar (cedar's softer grain hides screw heads better than the harder composites that benefit from hidden fasteners). 1/4-inch gap between boards for drainage and expansion.
Framing — PT Standard, Full Cedar Upgrade
Standard cedar builds use pressure-treated southern yellow pine framing — joists, beams, posts — which is the right structural choice for ground-contact and wet-exposure framing under cedar decking. Full-cedar framing is an upgrade option for premium builds where the homeowner wants the all-cedar aesthetic visible from below (a common request on elevated decks where the framing shows). Full-cedar framing adds approximately $4,000 to $8,000 to the build cost depending on size and runs slightly shorter life on the framing side than PT (cedar framing is not pressure-treated and is more vulnerable to ground-contact rot).
Hot-Dipped Galvanized or Stainless Fasteners — The Cedar-Specific Detail
Cedar contains natural acids (tannins) that corrode certain fastener grades faster than the equivalent fasteners would corrode in untreated wood. We use hot-dipped galvanized or stainless steel fasteners on every cedar build — never electroplated zinc. Stainless is the upgrade for premium builds. Standard galvanized fasteners stain cedar around the screw head (the dark rings every aging cedar deck shows around its non-stainless screws) and corrode faster against cedar's tannins than the harder framing screws designed for PT.
Cedar Railing and Cap Rail
Cedar 2x4 capped railing system on every cedar build — vertical cedar balusters (1.5-inch on-center at the 4-inch sphere rule), cedar 2x4 top rail capped with a cedar cap. The aluminum baluster upgrade replaces the vertical cedar balusters with powder-coated aluminum for a thinner-baluster modern look at $3,000 to $5,000 added cost. The cap rail on every cedar build gets routed and sanded smooth for hand contact.
Stain-and-Seal First Coat Included
Every Handis cedar build includes the first coat of stain-and-sealer applied after install (or left raw at the homeowner's request for natural weathering to silver-gray). We use semi-transparent oil-based stains from the major Pacific Northwest brands (Cabot, Penofin, Sikkens, or Defy) — the right product for cedar's pore structure, allowing the wood grain to read through while protecting against UV and moisture. The homeowner re-stains every 18 to 24 months on the standard maintenance cycle to keep the color; cedar left unstained weathers to silver in 12 to 18 months and stays that color through the deck's life.
How a Cedar Deck Build Works
Seven sequential phases from site staking through stain-and-seal first coat — the actual sequence Handis runs on every new western red cedar deck build.
Site Staking + Footing Layout + Permit
Estimate visit confirms the footprint, the cedar grade and dimension (5/4x6 standard or 2x6 upgrade), the framing material (PT standard or full cedar upgrade), the railing (cedar standard or aluminum baluster upgrade), and any add-ons. Site staked, footing locations marked, Seattle DCI permit pulled under Handis's general-contractor license. Stamped engineering coordinated if required.
Concrete Piers (or Helical Piers) + Post Bases
Pier footings poured to engineer's spec or to prescriptive depth — typically 18 to 36 inches deep. Galvanized or stainless post bases set into the wet concrete or anchored to cured piers.
Framing + Ledger (PT or Full Cedar)
Standard builds frame in pressure-treated southern yellow pine (the right ground-contact framing material under cedar decking). Full-cedar framing on upgrade builds. On attached builds, the wall behind the ledger is opened, bottom plate inspected and replaced if rotted, then the ledger through-bolted with 1/2-inch hot-dipped galvanized or stainless lag bolts at IRC R507.9.1.3 spacing and Z-flashed under the siding.
Framing Inspection
Seattle DCI (or jurisdiction equivalent) framing inspection. Inspector verifies pier spacing, joist hangers, ledger bolt pattern and flashing, post bases. Decking install holds until the framing inspection passes.
Cedar Decking Install with Stainless or Hot-Dipped Fasteners
Western red cedar 5/4x6 decking laid out, top-driven with stainless steel or hot-dipped galvanized deck screws sized for cedar (never electroplated zinc), set flush in the board, 1/4-inch gap between boards for drainage. Picture-frame border at the perimeter on premium builds.
Cedar Railing + Cap Rail + Fascia
Cedar 2x4 capped railing system at 36-inch (or 42-inch on raised decks per WA Residential Code), 4-inch sphere baluster spacing rule met. Cedar fascia installed at the rim joist. Cap rail routed and sanded smooth for hand contact.
Stain-and-Seal First Coat + Final Inspection
First coat of semi-transparent oil-based stain-and-sealer applied after install (Cabot, Penofin, Sikkens, or Defy — the right products for cedar's pore structure). Final inspection scheduled with the permit office. Inspector verifies railing height and baluster spacing, stairs and stair railings, and overall completion. Permit closed, permit copy provided. Maintenance schedule (re-stain every 18 to 24 months) explained at handoff.
Cedar Deck Pricing
Final pricing depends on deck square footage, cedar grade (5/4x6 standard or 2x6 upgrade), framing material (PT standard or full cedar upgrade), railing system (cedar standard or aluminum baluster upgrade), and whether stamped engineering is required. Engineering, Seattle DCI permit fees, and any licensed-electrical portions are pass-through line items named in the project total. Request a free in-home estimate for an accurate quote.
Tell us the square footage, the framing preference (PT standard or full cedar upgrade), and the railing material — we will quote the project with permit and engineering included.
Hot-dipped galvanized or stainless fasteners — never electroplated zinc on cedar
Cedar's natural tannins corrode electroplated zinc fasteners within a few seasons — the dark rings around screw heads on aging cedar decks are the visible signature of the wrong fastener grade. We use hot-dipped galvanized as standard and stainless steel as upgrade on every cedar build. The fastener spec adds dollars to the build; it adds decades to the deck.
Stain-and-seal first coat included
Every Handis cedar build includes the first coat of semi-transparent oil-based stain-and-sealer applied after install — Cabot, Penofin, Sikkens, or Defy, the right products for cedar's pore structure. We explain the 18 to 24-month re-stain cycle at handoff and provide the product specifications for the homeowner's future maintenance. Cedar left raw weathers to silver in 12 to 18 months and stays silver for the deck's life — also an acceptable choice, and we ask on the booking call.
IRC ledger schedule, through-bolted, Z-flashed, bottom-plate-inspected
Every attached cedar-deck ledger gets through-bolted with 1/2-inch hot-dipped galvanized or stainless lag bolts at 16-inch on-center staggered top/bottom per IRC R507.9.1.3, Z-flashed under the siding with the flashing leg tucked behind the WRB, and the wall behind the ledger gets opened, the bottom plate inspected, and replaced if rotted.
PT framing under cedar decking — the right structural choice
Pressure-treated southern yellow pine framing (joists, beams, posts) is the standard structural choice under cedar decking. PT is rated for ground-contact and wet-exposure framing and lasts longer in that service than cedar would. Full-cedar framing is an upgrade option for builds where the homeowner wants the all-cedar look visible from below — we will tell you the tradeoff (cedar framing has shorter ground-contact life than PT) on the booking call.
Cedar railing routed and sanded smooth for hand contact
Every Handis cedar railing system gets the cap rail routed and sanded smooth on the top edge for hand contact. The deck rail is a working surface that hands cross every time someone goes up or down the stairs; a rough or splintered cap rail is the kind of detail homeowners notice every time they touch it.
Insured, background-checked, 2-year structural + 1-year decking warranty
Handis carries general liability and workers' compensation; every carpenter has cleared a background screening. Two-year Handis warranty on structural framing — joists, beams, posts, ledger flashing. One-year Handis warranty on cedar decking install, cedar railing, cap rail, fascia, and stain-and-seal application. The natural-wood material itself (splitting, checking, warping that falls within normal cedar's lifecycle) is not under warranty; that is the maintenance cycle the homeowner commits to.
Estimate
Tell us the square footage you have in mind, the cedar grade preference (5/4x6 standard or 2x6 upgrade), the framing preference (PT standard or full cedar upgrade), the railing system (cedar standard, aluminum baluster upgrade), the stain preference (semi-transparent oil first coat, or left raw for natural silver-gray weathering), and any add-ons (stairs, built-in bench, low-voltage lighting, hot-tub framing). We send a clear estimate with the cedar spec, the stain spec, and the permit/engineering pass-through line items named.
Customer Reviews
Recent cedar deck reviews from real Handis customers across the Puget Sound.
280-square-foot western red cedar deck on our Magnolia back yard. 5/4 by 6-inch decking, PT framing, hot-dipped galvanized fasteners, semi-transparent Cabot stain in honey color. Handis built it in 9 working days, pulled the Seattle DCI permit. The first coat of stain was applied the day after the decking went down and the deck reads warm and intentional. Came in at $19,500.
Cedar deck with the stainless steel fastener upgrade on our Ballard build. We had the previous cedar deck (1996) that had the dark rust rings around every screw head and we did not want that on the new one. Handis used stainless steel deck screws throughout — no rust rings, no staining, and the screws will outlive the deck. $22,500 for 320 square feet. The right call for the long horizon.
Full-cedar framing build on a 380-square-foot elevated deck in Bellevue — the framing is visible from below and we wanted the all-cedar aesthetic. Handis explained the tradeoff (shorter framing life than PT), helped us decide we wanted the look enough to accept the maintenance, and built the deck in three weeks. Cedar joists, beams, posts, decking, railing, cap rail. $34,000 total. Reads like a single piece of furniture.
480-square-foot cedar deck (left raw, no stain) on our Queen Anne back yard. We wanted the silver-gray weathered look from day one and Handis was happy to skip the first-coat stain. The deck has been in service 14 months and has weathered to a beautiful silver-gray that fits the Craftsman house perfectly. Cedar 2x6 boards, hot-dipped galvanized fasteners. $26,000 total.
Cedar deck with aluminum baluster railing upgrade. Cedar 5/4x6 decking, cedar cap rail and top rail, powder-coated aluminum balusters for the modern look. Handis routed the cap rail smooth — feels good under the hand on every trip up the stairs. 360 square feet, $28,500. The aluminum balusters keep the view to the bay open in a way wooden balusters would have blocked.
