Cedar Siding Seattle — Install It Right or You’ll Be Repainting in Three Years
Cedar siding is beautiful, natural, and genuinely durable — if installed correctly. In Seattle’s wet climate, shortcuts kill cedar fast. Every Seattle cedar siding installation we do — Western Red Cedar, across King and Snohomish Counties — is done the right way: six-side primed, oil-based primer, ventilated rainscreen, proper flashing at every window and penetration.
Budgeting the stain cycles matters as much as the install price — our 10- and 20-year maintenance cost table shows what cedar really costs to keep beautiful next to Hardie, LP, and metal.

What Homeowners Say
Real reviews from our Google profile — unedited, from real projects.
“We recently had Paul with GP General repair a damaged corner protector and sidings. His estimate was reasonable, his availability was timely, and his job was excellent. Our home hadn’t been re-painted in a while and the paint had considerably faded, yet he was able to match the color perfectly. Now we know who to turn to when in need of another repair work.”
“GP General replaced LP siding on our garage. Paul was very thorough when he came out to do the estimate; he listened to my concerns and was able to work out solutions on the spot. His crew did a great job and were very courteous. They also were careful about cleaning up (I didn’t find any nails!). Really happy with the job and can recommend GP General.”
“I highly recommend GP General Corp for siding replacement. We recently had our wood siding replaced with James Hardie lap siding, and Paul and his team did an excellent job.”
Why Western Red Cedar Is Still the Right Choice for Many Seattle Homes
Fiber cement dominates the Seattle re-siding market — and for good reason. But cedar remains the superior choice in specific situations. The trick is knowing which category your home falls into.
Western Red Cedar has a grain depth and warmth that no manufactured product replicates. On Craftsman homes in Fremont, bungalows in Wallingford, and mid-century homes on Capitol Hill, cedar is architecturally correct in a way that fiber cement and engineered wood are not. When maintained properly, cedar develops a rich patina that synthetic materials can’t match.
Cedar heartwood contains natural thujaplicins — organic compounds that resist fungal decay, insect damage, and moisture absorption. These aren’t unlimited (they degrade over 40–60 years), but they give cedar a significant advantage over untreated softwoods. When combined with proper installation, cedar performs exceptionally in the Pacific Northwest’s wet conditions.
Cedar has one of the lowest shrink-swell coefficients of any commercial softwood. In Seattle’s constant wet-dry cycling, this matters: cedar moves less than fir, pine, or spruce siding, which means fewer gaps opening at joints and less paint film stress. Less movement = longer paint life = fewer maintenance cycles over the lifespan of the siding.
Cedar is not the right choice for every home. Homes with heavy tree canopy on north-facing elevations, homes where the owner doesn’t want to commit to periodic stain maintenance, or budget-constrained projects where material cost per square foot matters most — in those situations, James Hardie fiber cement or LP SmartSide is a better fit. We’ll tell you honestly which category your home falls into.

How We Install Cedar Siding in Seattle — The Details That Make It Last
Most cedar siding failures in Seattle trace back to installation shortcuts, not material defects. Here is exactly how GP General Corp installs cedar — and why each step matters in the Pacific Northwest.
Every cedar board is primed on all six sides (front, back, both edges, both ends) with an oil-based primer before it goes on the wall. This seals the wood against moisture absorption from every direction — including the back face that sits against the wall assembly. Most contractors skip back-priming. In Seattle’s climate, unprimed backs absorb moisture from the wall cavity, causing cupping, warping, and premature paint failure.
We install a code-compliant WRB — properly lapped, taped at all seams, and integrated at every window and door flange. The WRB is the second line of defense behind the cedar: any moisture that makes it past the siding surface hits the WRB and drains down rather than into the sheathing. On older Seattle homes, we frequently find no WRB at all behind the original cedar. Learn more about moisture management and WRB systems.
We install a 3/8” ventilated drainage gap between the WRB and the back of the cedar siding using furring strips or a drainage mat like HydroGap. This gap allows any moisture behind the siding to drain out at the bottom and lets air circulate to dry the wall assembly. This single detail extends cedar lifespan by 15–20 years in Seattle’s climate compared to cedar installed flat against housewrap. See our rainscreen systems page for the full explanation.
Cedar’s natural tannins react with standard galvanized and electro-plated fasteners, causing dark streaking down the siding face. We use stainless steel ring-shank nails on every cedar project — they don’t react with the tannins, they resist corrosion indefinitely, and they hold better in the PNW’s damp conditions than standard fasteners.
Every window, door, vent, hose bib, and electrical penetration gets properly flashed — with kickout flashings at roof-wall intersections, head flashings above windows, and correctly lapped integration with the WRB. Failed or missing flashings are the #1 cause of dry rot behind cedar siding in Seattle.
Every field-cut end is sealed with primer before installation. End grain absorbs moisture at 10–15x the rate of face grain — an unsealed cut end in a joint or at a trim transition is an open moisture pathway into the board. This is another step most contractors skip because it slows production. We do it on every cut, every board.
Cedar Grades and Profiles We Install
Not all cedar is the same. Grade, profile, and species all affect performance, appearance, and cost. Here’s what we work with and when each makes sense.
Tight-grain, knot-free Western Red Cedar heartwood. This is the premium choice for visible, high-quality residential siding. Clear grade holds paint and stain most uniformly, has the highest natural decay resistance (all heartwood, minimal sapwood), and delivers the cleanest appearance. Recommended for primary residential siding on homes where appearance and longevity are the priority.
Sound, tight knots in an otherwise clear board. STK cedar is structurally sound and performs well with stain finishes that embrace the knotty character. A cost-effective step down from clear grade — appropriate for accent areas, gable ends, or homeowners who prefer a more rustic aesthetic. Not recommended for paint finishes, as knots bleed through paint over time.
The most common cedar siding profile in Seattle. Boards are thicker at the bottom and thinner at the top, overlapping to shed water. Available in 6”, 8”, and 10” nominal widths. Wider reveal (the visible face) creates a more contemporary look; narrower reveal is traditional for Craftsman and bungalow-style homes.
Interlocking profile that creates a tight, flat surface. Common on soffits, porches, and accent walls. Can be installed horizontally or vertically. In Seattle, T&G cedar requires careful back-priming because the interlocking joints can trap moisture if the drainage plane isn’t correctly detailed.
Machine-cut shingles and hand-split shakes provide a textured, dimensional exterior common on Cape Cod, Craftsman, and Pacific Northwest-style homes. Shingles are uniform thickness; shakes have a rougher, more rustic surface. Both require back-ventilation and are best installed over furring strips for drainage in our climate.
Vertical boards with narrow batten strips covering the joints. A classic farmhouse and contemporary profile that’s increasingly popular on modern Seattle renovations. Vertical installation sheds water differently than horizontal lap — the WRB and flashing details are even more critical. We detail every joint for drainage.

Cedar is a premium material and costs more than fiber cement or engineered wood. The payoff is natural beauty, architectural authenticity, and — when installed correctly — a 30–40 year service life in Seattle’s climate. Here are realistic installed price ranges as of 2025:| Product | Installed Cost (per sq ft) | Notes |
|---|---|---|
| Clear Grade Bevel (Lap) | $30–$40 | Premium residential choice. Includes six-side priming, WRB, rainscreen, stainless fasteners. Paint or stain finish additional. |
| Select Knotty Bevel | $13–$19 | Budget-friendly cedar option with natural knotty character. Best with penetrating stain finish. |
| Cedar Shingles | $20–$40 | Labor-intensive installation. Higher per-square-foot cost reflects the number of individual pieces per wall area. |
| Board-and-Batten (Vertical) | $17–$25 | Increasing in demand on contemporary renovations. Requires careful WRB and joint detailing for vertical orientation. |
| Typical Seattle Home (1,500–2,500 sq ft wall area) | $24,000–$60,000+ | Full replacement with clear-grade bevel cedar, six-side prime, rainscreen, WRB, flashing, trim. Substrate repair additional. |
Prices include material, labor, WRB, rainscreen furring, and stainless fasteners. Does not include paint/stain finish, substrate repair if rot is found, or permit fees ($300–$700 in most Seattle-area cities). Request a free assessment for an accurate written quote.
Cedar Siding Maintenance in the Pacific Northwest
Cedar is not a set-it-and-forget-it material. In Seattle’s climate, it requires periodic maintenance to perform at its full potential. Here’s what to expect and how to budget for it.
Repainting cycle: Every 7–10 years on properly installed cedar with six-side priming and a rainscreen. Without back-priming, paint fails in 3–5 years as moisture pushes through from behind. South and west elevations fade and chalk faster than north and east.
Typical repaint cost: $4–$7 per square foot for prep, prime, and two coats of premium acrylic latex. For a 2,000 sq ft home: $8,000–$14,000 per repaint cycle.Re-staining cycle: Every 3–5 years for semi-transparent penetrating stains. Solid-body stains last longer (7–10 years) but obscure the natural grain. Penetrating stains are preferred for homes where the cedar grain and natural color are the design intent.
Typical re-stain cost: $3–$5 per square foot. Less prep than repainting because penetrating stains don’t peel — they fade and wear, which is easier and faster to recoat.Annual inspection: Walk your home once a year and check bottom courses, window/door transitions, and any area where siding meets trim. Probe any soft spots. Catch problems early — a $200 caulking repair at a window corner prevents a $4,000 dry rot restoration three years later.
Cedar vs. James Hardie Fiber Cement — Honest Comparison
Cedar and Hardie solve different problems. Here’s where each one wins — and where it falls short.
| Factor | Western Red Cedar | James Hardie Fiber Cement |
|---|---|---|
| Material Cost | Higher ($5–$9/sq ft material only) | Lower ($3–$6/sq ft material only) |
| Installed Cost | $20–$30/sq ft | $14–$20/sq ft |
| Lifespan (properly installed) | 30–40 years | 40–50+ years |
| Moisture Absorption | Absorbs moisture (mitigated by priming and rainscreen) | Does not absorb moisture |
| Maintenance | Repaint/re-stain every 3–7 years | Repaint every 10–15 years (ColorPlus longer) |
| Manufacturer Warranty | None (depends on maintenance) | 30-year transferable (non-prorated) |
| Aesthetic | Natural wood grain, warmth, aging character | Clean, uniform, painted appearance |
| Best For | Craftsman, bungalow, character homes where wood is architecturally correct | Most Seattle homes, especially moisture-prone neighborhoods |
| Fire Resistance | Combustible (Class C untreated) | Non-combustible (Class A) |
Our recommendation: If your home’s architectural character depends on natural wood — and you’re willing to invest in proper installation and periodic maintenance — cedar is the right choice. If you want the lowest total cost of ownership over 30 years, or if your home has heavy shade and moisture exposure, Hardie fiber cement is almost always the better investment. We’ll give you an honest assessment of which makes sense for your specific home.

Cedar Siding vs. Vinyl Siding — Which Lasts Longer in Seattle?
Properly installed cedar siding lasts 30–50 years in Seattle; vinyl siding lasts 15–25 years before fading, brittling, or warping in the PNW climate. Both are valid choices — vinyl wins on upfront cost and zero maintenance, cedar wins on durability, repairability, resale value, and curb appeal. Here’s the honest breakdown of when each makes sense for a Seattle home.
Cedar Siding Durability vs. Vinyl
Cedar siding durability in Seattle averages 30–50 years when installed over a vented rainscreen with six-side priming and a maintained finish. Western Red Cedar contains natural oils (thujaplicin, thujone) that resist fungal decay and insects. Alaskan Yellow Cedar lasts even longer (40–60 years) but costs 30–40% more. Vinyl siding has a manufacturer warranty of 25–30 years but real-world Seattle performance is 15–25 years — UV breaks down the surface pigment, freeze-thaw cracks panels along the nailing flange, and wind storms snap individual lengths that can’t be color-matched at replacement.
How to Maintain Cedar Siding (vs. Zero-Maintenance Vinyl)
Cedar siding requires re-staining or re-sealing every 3–7 years in Seattle, depending on finish type and exposure. Clear oil finishes (Penofin, Sikkens Cetol) need recoating every 3–5 years on south and west walls, every 5–7 years on shaded north walls. Solid stains last 5–7 years. Annual maintenance: pressure-wash with a low-pressure tip and mild detergent, inspect caulk lines, spot-touch up any boards showing finish wear, and check that the rainscreen ventilation slots at the bottom and top of walls are clear of debris.
Vinyl siding maintenance is essentially nothing — an annual rinse with a garden hose, that’s it. The trade-off is that when vinyl fails (cracks, fades unevenly, or storms damage one section), you can’t simply patch and refinish. The original color batch is rarely available 10+ years later, and partial replacement results in two-tone walls. Cedar fails gracefully — one rotted board gets replaced, the new board gets oiled to match, and the wall keeps looking right.
Cedar vs. Vinyl Siding: Installation Cost in Seattle
Real Seattle pricing (2026):
- Vinyl siding: $6–$10 per square foot installed — the lowest-cost siding option, including basic WRB and direct-to-stud install.
- Cedar siding: $20–$40 per square foot installed (including HydroGap Drainable WRB and vented rainscreen), depending on grade (#3 Common up to Clear Vertical Grain), profile (bevel, T&G, board-and-batten, shingle), and finish.
A 2,000 sq ft Seattle home (~3,000 sq ft of wall area) lands around $18,000–$30,000 for vinyl, $60,000–$120,000 for cedar. Cedar is 3–4× more expensive upfront but the lifecycle cost over 40 years is closer than the install cost suggests once you factor in vinyl’s mid-life replacement and cedar’s higher resale value.
Cedar vs. Vinyl: Curb Appeal & Resale Value
Cedar siding adds approximately 78% to home value at resale per the 2024 Cost vs. Value Report (Pacific region); vinyl adds approximately 65%. Beyond the dollar figure, cedar carries stronger emotional appeal in Seattle’s housing market — buyers in Magnolia, Queen Anne, Bellevue, and Mercer Island consistently price cedar-clad homes higher than identical vinyl-clad comps. Vinyl reads as “mass market builder grade” on Eastside teardown lots; cedar reads as “intentional craftsmanship.”
When Vinyl Wins, When Cedar Wins
Vinyl is the right call when: the property is a rental, an investment flip, or a starter home where you need siding to last 15 years for the lowest possible cost; you genuinely cannot or will not maintain a finish; or HOA rules in your subdivision prohibit natural-wood siding (rare in Seattle but exists in some King County subdivisions).
Cedar is the right call when: you plan to live in or own the home for 15+ years; the architecture is Craftsman, traditional, modern PNW, or any style where natural wood is part of the design intent; resale value matters; or you live in a Seattle neighborhood where vinyl would noticeably underprice the home (most of central Seattle, Mercer Island, the Bellevue west slope, Eastside lakefront).
