Why Bothell Homeowners Choose Us
Cedar Replacement Specialists
We've torn out and replaced dozens of 2000s-era cedar decks in Canyon Park and Queensborough. We assess the frame honestly — if the structure holds, resurfacing with composite saves you significant cost over full demolition.
Norway Hill Grade Engineering
Norway Hill's elevation changes require hillside deck engineering: deeper footings, elevated posts, lateral cross-bracing. We assess every site individually and provide estimates that account for grade complexity — no surprises after you sign.
Honest Mid-Range Pricing
Bothell deck replacements typically run $18K–$40K. Our estimates are fully itemized — material, labor, permit, demolition — so you can compare apples to apples. No vague ranges, no change orders for things we knew were coming.
Canyon Park's Cedar Wave — And the Buyers Who Don't Want Another Maintenance Project
The 2000s building boom in Canyon Park, Queensborough, and North Creek produced thousands of cedar decks that are now 18–22 years old. In Bothell's climate, that's end-of-life for surface boards — and often ledger-and-post territory too. The frame assessment is free. If the structure is sound, resurfacing with composite saves $8,000–$12,000 over a full tear-out. If it's not, we'll tell you that directly.
The younger buyers coming into Bothell through UW Bothell and the Canyon Park tech corridor don't want a staining weekend every two years. They want low-maintenance composite that looks good and stays that way. That's most of what we install in Bothell now — mid-range Trex Select or TimberTech Terrain at a price point that makes sense for this market.

Google Rating
Bothell stretches along the I-405 corridor from Canyon Park in the south through North Creek to the Snohomish County line — a mix of 1990s ramblers and 2000s-era builds in Canyon Park and Queensborough, newer construction near UW Bothell and the North Creek tech corridor, and the steeper hillside lots of Norway Hill that demand a different kind of deck engineering. Cedar decks from the 1990s and early 2000s building wave are hitting end-of-life throughout this corridor right now, and we've been working through that replacement cycle for three years. We know what's under those boards before we open them.
forestCanyon Park & Queensborough: The Cedar Replacement Wave
The 2000s building boom in Canyon Park, Queensborough, and North Creek produced thousands of cedar decks — and those decks are now 18–22 years old. In Bothell's wet climate, that's end-of-life for surface boards, and often ledger-and-post territory too. We've been working through this replacement cycle for three years and we know exactly what we're going to find under those boards.
Signs that a 2000s Bothell cedar deck is ready to go: boards that flex noticeably underfoot, dark staining at the ledger connection that won't come clean, soft spots near post bases, and railings that move more than an inch under pressure. Any one of these means it's time for an assessment.
The frame assessment is always free. If the ledger, beams, and post bases are sound, resurfacing with composite saves $8,000–$12,000 over full demolition and rebuild. If the structure has failed, we'll tell you that directly and price the full replacement honestly. We don't recommend replacements when resurfacing is the right answer.
apartmentUW Bothell & Canyon Park Tech: Low-Maintenance Is the Priority
The younger professionals coming into Bothell through the UW Bothell campus and Canyon Park tech corridor are buying their first homes — and they have no interest in a staining weekend every two years. Mid-range composite is the product they want: Trex Select, TimberTech Terrain, Fiberon Symmetry. These run $22,000–$35,000 for a standard 300–400 sq ft replacement, include a 25-year warranty, and require cleaning once a year.
Bothell pricing is genuinely more moderate than Bellevue or Sammamish — partly because lots are flatter, partly because project scope is more standardized. We don't inflate estimates for this market. If a Trex Select replacement is the right product for your situation, that's what we'll quote.
terrainNorway Hill & North Creek: Grade Changes and ECA Buffers
Norway Hill is the exception to Bothell's generally flat topography. The significant elevation changes in that neighborhood require hillside deck engineering: deeper footings, taller post systems (sometimes 8–10 feet), and lateral cross-bracing to meet seismic requirements. We assess every Norway Hill site individually before quoting — the footing and post requirements on a steep lot can meaningfully change project cost, and we won't give you a flat estimate without seeing the grade.
For properties near the North Creek corridor or the Sammamish River, we check for Environmentally Critical Area (ECA) buffers on the first site visit. Lots within 100 feet of a mapped watercourse require a pre-application coordination step before permit submission. Most Canyon Park and Queensborough properties aren't affected, but it's a check we run on every Bothell project — discovering it mid-permit is a costly delay.
Did You Know?
Bothell is the fastest-growing city in northeastern King County — population grew 45% between 2010 and 2023. The University of Washington Bothell campus and Canyon Park business district anchor a tech and healthcare employment hub that has transformed the city's residential market. New homeowners in North Creek, Canyon Park, and Kingsgate (Bothell's unincorporated Kirkland border) are the primary driver of new deck additions — first-time builds on newer homes rather than replacements.
categoryChoosing the Right Material for a Bothell Deck
Bothell's climate is wetter than Seattle averages — the North Creek valley and Norway Hill's east-facing slopes trap fog and rain longer than open Eastside lots. That moisture exposure matters more than most homeowners expect when choosing between cedar, composite, and PVC.
| Material | Lifespan | Maintenance | Shaded Lots | Best For |
|---|---|---|---|---|
| Western Red Cedar | 15–25 yrs | Seal every 1–2 yrs | Requires more frequent sealing | Budget builds, classic look |
| Capped Composite | 25–30 yrs | Annual wash only | Resists mold by design | Most Bothell replacements |
| PVC (AZEK, TimberTech Pro) | 30+ yrs | Minimal — hose off | Zero water absorption | North Creek / wet microclimate lots |
For most Bothell cedar replacements, mid-range capped composite (Trex Select or TimberTech Terrain, $22K–$35K) is the right answer. North Creek lots with consistent moisture and minimal sun should consider upgrading to PVC — the additional $3,000–$5,000 at install eliminates any mold or moisture concern for the life of the deck.
Bothell Deck Cost Guide

Did You Know?
The Sammamish River winds through Bothell's downtown and the Riverside neighborhood before flowing south through Woodinville wine country to Redmond. Properties along the Sammamish River (Riverside Dr area, downtown Bothell park zone) have one of the few riparian deck opportunities in King County's north suburbs. River-adjacent projects require shoreline setback review — but the deck views over the river corridor are among the most unique in the region.

City of Bothell permit: 3 weeks. $17,800 installed.
Norway Hill — Elevated Composite Build
280 sq ft elevated deck on a steeply sloped Norway Hill lot. Center posts at 9 feet required engineered cross-bracing and stamped foundation plan. TimberTech Terrain composite surface, aluminum balusters. Engineering added $1,800 to cost but City permit sailed through without revision. $44,200 installed.
Queensborough — New Deck + Pergola Provision

North Creek — Full Cedar Replacement, PVC
350 sq ft 2001-era cedar deck — frame failed at two post bases from ground contact moisture. Full demo and rebuild with AZEK PVC (zero water absorption) suited to the wet North Creek microclimate. Lot checked for ECA buffer — 140 feet from creek, no pre-application meeting required. $38,900 installed.
gavelDeck Permits in Bothell — What to Expect
City of Bothell requires a building permit for any new deck, any deck addition over 200 sq ft, any deck over 30 inches above grade, and any structural repair that modifies the framing. Resurfacing-only projects (replacing boards over an intact frame) typically don't require a permit if no structural work is involved — we confirm this at your estimate visit.
Standard Bothell permit review: 3–5 weeks. Norway Hill elevated decks with engineered drawings: 4–6 weeks. Properties near North Creek or the Sammamish River with ECA buffers may require a pre-application meeting with the City before permit submission — add 2–3 weeks. We manage all permit documentation, City coordination, and inspection scheduling. Permit fees typically run $350–$650 depending on project valuation and are included in our project estimate as a line item.
North Bothell — 340 sq ft Cedar Deck Replacement, TimberTech Terrain Composite
This North Bothell home near the 405 interchange was built in 1997 — the cedar deck was original and had never been replaced. Surface boards had developed significant soft spots near the ledger connection, and the homeowner had noticed the railings flexing under light pressure. On our assessment visit, we found the ledger and primary beam structure still sound, but two post bases had significant rot at grade from years of ground contact moisture. Rather than a full tear-out, we replaced the failed post system and resurfaced with TimberTech Terrain composite — saving approximately $9,200 compared to a full demolition and rebuild. City of Bothell permit processed in 3.5 weeks. The new composite surface requires only an annual clean. Total project: $26,800 including post replacement, permit, and full TimberTech Terrain resurfacing with new aluminum balusters to meet current code railing spacing.
Kenmore Area (South Bothell Corridor) — 380 sq ft New Composite Deck, Cable Railing, Trex Transcend
This Kenmore home — just south of the Bothell border on the 522 corridor — had never had a deck. The homeowners wanted something that would require zero maintenance and hold up under the heavy shade from mature bigleaf maples on the rear lot line. We specified Trex Transcend in Lava Rock (a charcoal gray that reads well in shade without showing algae discoloration) with stainless cable railing for an open sightline toward the landscaped backyard. The lot had a modest rear grade of about 6 feet — standard elevation requiring concrete pier footings, no structural engineering stamp needed. City of Kenmore permit ran 4 weeks. Build completed in 8 days. Total: $41,500 including permit, concrete footings, full Trex Transcend composite decking, and stainless cable railing system with TimberTech aluminum posts.
Q: My Bothell home was built around 2003 with a cedar deck — is it time to replace it?
Likely yes, or soon. Cedar decks from the early-2000s building boom are now 20+ years old — prime replacement age, especially in Bothell's wet climate. Signs to look for: boards that flex noticeably when walked on, dark staining that doesn't come clean, soft spots near ledger connections or post bases, and railings that move more than an inch under pressure. We offer free deck assessments — we'll tell you honestly whether repair or replacement makes more sense.
Q: What is the cost range for a deck replacement in Bothell?
Bothell deck replacement projects typically run $18,000–$40,000 for a standard 300–400 sq ft project, depending on material and complexity. Cedar replacement with composite runs $22,000–$35,000. PVC replacement runs $28,000–$42,000. These include full demolition of the old deck, permit, and construction. We provide free itemized estimates so you know exactly what you're paying for.
Q: Do you serve North Bothell and the Norway Hill area?
Yes — Norway Hill is a regular service area for us. The grade changes in that neighborhood often result in elevated deck requirements and can add cost for footing depth and post height. We assess every Norway Hill site individually to provide an accurate estimate. Permit handling is through City of Bothell for Norway Hill properties (not unincorporated King County in most cases, though verify your parcel).
Q: Is composite or cedar better for Bothell's shaded, wooded lots?
Capped composite is almost always the better long-term choice for Bothell's tree-canopy lots. Shaded decks stay damp longer, which accelerates mold and checking on bare wood surfaces. Cedar holds up well structurally but requires sealing every 1–2 years in shaded conditions — skipping that cycle leads to surface cracking and board cupping by year 5–6. Capped composite (Trex, TimberTech, Fiberon) resists mold by design, cleans with a hose, and carries a 25-year warranty. The premium at install pays back in avoided maintenance within 6–8 years for most Bothell homeowners.
Q: How long does the permit process take in Bothell?
City of Bothell permit review typically takes 3–5 weeks for a standard deck replacement or new build. Projects on Norway Hill lots with engineered drawings add 1–2 weeks for plan review. Lots near the North Creek or Sammamish River corridors with ECA buffers require a pre-application meeting with the City before permit submission — add 2–3 weeks. We handle all permit documentation and agency coordination as part of our project management scope. You don't deal with the permit office — we do.
Q: Can you build a deck in fall or winter in Bothell?
Yes — we build year-round. Concrete footings cure slower in cold weather but are unaffected by rain. Composite and PVC decking installs fine in wet conditions. We do schedule framing work around hard rain events when possible (wet pressure-treated lumber expands, creating minor fastener issues), but a typical Bothell October or November doesn't stop a project. Winter builds have a real advantage: permit times are shorter (less volume), material availability is better, and our crew schedule is more flexible for a faster construction timeline. Fall and winter are our best seasons for scheduling.
mapBothell Neighborhoods: Where We Build and What to Expect
Canyon Park and Queensborough — east of I-405 off SR 527 — hold the highest concentration of aging cedar decks and are where most of our Bothell replacement work originates. Lots here are typically 7,000–10,000 sq ft with modest rear grades; the standard project is a 300–400 sq ft deck replacement at 6–8 feet above grade. North Creek neighborhoods along the 195th–202nd Street corridors trend newer with larger lots (8,000–14,000 sq ft), and requests here lean toward first-time composite builds rather than replacements, often with a pergola rough-in.
The Kingsgate area along NE Juanita-Woodinville Way straddles the Bothell–Kirkland border. Permit jurisdiction depends on the parcel address — some Kingsgate properties file with City of Bothell, others with City of Kirkland. We verify jurisdiction at the estimate appointment so permit submissions go to the right office the first time. See our Kirkland deck builder page for coverage of the adjacent neighborhoods south of the border.
Norway Hill lots north of 240th Street typically range 10,000–22,000 sq ft with steep rear grades — every Norway Hill project begins with an on-site grade assessment before we quote, because the footing and post requirements on a 20% slope can shift project cost by $8,000–$15,000. All Bothell-addressed deck permits are processed through the City of Bothell Community Development Department at bothellwa.gov; online permit submission is available and most standard residential deck applications receive initial plan-reviewer assignment within 5–7 business days of a complete submittal.
We build throughout North King County. Kirkland and Redmond are our Eastside neighbors — similar Norway Hill grade engineering applies across all three cities. Sammamish shares Bothell's forested lot conditions. For premium Eastside builds, see Bellevue.
Bothell Outdoor Living: Landmarks & Local Connections
golf_course Wayne Golf Course (South Bothell)
18-hole public course along the Sammamish River, near the Kenmore border. Adjacent residential neighborhood (220th St SE, Wayne Golf Course Rd) has large lots and elevated positions with views over the course and river. This is Bothell's premium deck market — golf course frontage lots typically spec cable railing and premium composite.
route Sammamish River Trail
Continues from Redmond through Bothell on its way to Woodinville. River-adjacent properties along Riverside Dr NE and NE Bothell Way waterfront corridor have unique sightlines over the river. Shoreline setback review applies to any deck project within 100 feet of the Sammamish River — we check this on the first site visit.
park Bothell Landing Park
Downtown Bothell's historic waterfront park on the Sammamish River. Adjacent residential streets have unique river-view deck positions. Bothell Historic District review may apply to properties near the landmark corridor — an additional coordination step we manage as part of permit preparation.
directions_walk North Creek Trail
4.1-mile trail system through North Bothell and Kenmore. Adjacent North Creek neighborhood (NE 195th, 19th Ave NE) has newer homes — primarily first-time deck additions rather than replacements. Tech and healthcare employees from the Canyon Park corridor are the core demographic, and they want low-maintenance composite.
business Canyon Park Business District
Major tech and healthcare employment hub in NE Bothell. Adjacent Queensborough, Wellington, and Country Village residential neighborhoods have high homeowner income and strong deck investment appetite. Mid-range to premium composite is the standard product for this demographic — Trex Enhance, TimberTech Terrain, and up.
school UW Bothell / Cascadia College Campus
NE Bothell, Sammamish River corridor. Campus investment has driven surrounding residential values up significantly. Kenmore border neighborhoods (Lakehill, Lochsloy) benefit from proximity — property values rising, homeowners investing in outdoor living. We serve the full Kenmore–Bothell corridor with the same licensed crew.
landscape Maltby Area (SE Snohomish County Border)
Large rural lots just north of Bothell city limits. Big-footprint decks, more relaxed permitting through Snohomish County rather than Bothell city, agricultural-adjacent rural character. Homeowners here often want larger decks with pergolas and outdoor kitchen rough-ins. We build on both sides of the county line.
PNW Build Window
Bothell's build window runs April through October. North Creek neighborhoods see faster spring drying than downtown Bothell's river corridor. Wayne Golf Course and Sammamish River adjacent projects need shoreline setback assessment — call us for a site check before permit submission. Bothell/Kenmore permits run 3–5 weeks.
