Product Research
Fiberon's capped composite decking eliminates the wood deck maintenance cycle — no annual staining, no sealing, no board replacement from rot — at an accessible entry point for homeowners upgrading from pressure-treated wood. This guide explains how Fiberon's Pro-Tect Advantage works, how it differs from first-generation composite products, and when it's the right choice versus a higher-tier product.
A pressure-treated wood deck in Clark County or the Portland Metro requires consistent maintenance: annual cleaning in spring, restaining or resealing every 2–3 years, and progressive board replacement as surface checking and rot develop over 5–10 years despite treatment. Pacific Northwest rainfall — 40+ inches annually, concentrated in sustained winter events — accelerates every part of this maintenance cycle compared to drier climates.
Most homeowners don't perform this maintenance consistently. The result is a wood deck that looks weathered within 3 years, develops surface mold and biological growth as moisture is retained in surface checking, and requires major repairs or replacement within 10–15 years.
Capped composite decking replaces this cycle with soap-and-water annual cleaning. The capping technology is the critical difference from first-generation composite products that developed poor reputations in the 2000s — first-generation uncapped composite had exposed wood fiber that absorbed moisture and developed mold. Fiberon's Pro-Tect Advantage wraps all four sides of each board in a protective polymer cap that prevents moisture absorption by the wood fiber core.
The result: a deck surface that maintains its appearance without annual treatments, resists mold and staining, and does not require progressive board replacement from rot damage.
Fiberon Authorized + TimberTech Authorized
Left Coast Exteriors is authorized for both Fiberon and TimberTech products. This means we can make an honest product comparison across the full composite and PVC spectrum — from Fiberon's entry-level capped composite to TimberTech's premium AZEK cellular PVC — and match the product to the homeowner's budget and performance requirements without being locked into a single brand.

TimberTech Decking Guide →Fiberon's Pro-Tect Advantage is the accessible entry point for capped composite performance. Here's how the product works and who it's right for.
Wood fiber and polymer composite core protected by a four-sided polymer cap on every board. The cap prevents moisture absorption by the core — the failure mode that damaged uncapped first-generation composite. Surface texture replicates natural wood grain without wood's maintenance requirements. Available in multiple color options to complement home exterior color palettes.
Soap and water cleaning. Mold and mildew resistant at the surface. No staining, sealing, or annual chemical treatments required. Designed for standard Pacific Northwest residential deck exposure — typical suburban Clark County and Portland Metro backyard decks. For heavily shaded or water-adjacent applications, TimberTech AZEK is the better match.
Homeowners upgrading from pressure-treated wood who want genuine low-maintenance performance without stepping into the higher-cost TimberTech tier. Budget-conscious projects where the primary goal is eliminating the stain-and-seal maintenance cycle. Standard suburban deck builds and replacements in Vancouver, Beaverton, Portland, Gresham, and similar neighborhoods.
Entry-level capped composite does not offer the 50-year warranty or complete moisture immunity of TimberTech AZEK cellular PVC. For heavily shaded decks adjacent to water features, lakeside properties, or maximum-longevity applications, TimberTech Pro Legacy or AZEK is the better match. We tell homeowners this at the estimate — we don't sell Fiberon for applications where a higher-tier product is genuinely the right answer.
What distinguishes Fiberon Pro-Tect Advantage for Pacific Northwest moisture management at an accessible price point.
Polymer cap on all four sides protects the wood fiber core from moisture absorption. As long as the cap is intact, the underlying wood fiber is protected from Pacific Northwest moisture — the failure mode that gave first-generation uncapped composite products their poor reputation.
Fiberon Pro-Tect Advantage delivers the reduction in annual maintenance — no staining, no sealing, no board replacement from rot — at an accessible price point compared to TimberTech's Pro Legacy and AZEK lines. The right specification when upgrading from pressure-treated wood without the budget for the premium composite tier.
We're authorized for both Fiberon and TimberTech. When Pro-Tect Advantage matches the project's budget and exposure profile, that's what we recommend — without pushing homeowners into a higher tier than their situation warrants. When AZEK is the right answer, we say so.
Fiberon Pro-Tect Advantage costs more upfront than pressure-treated lumber but eliminates the 2–3 year restaining cycle and 5–10 year progressive board replacement cost. Over a 20-year deck life in Pacific Northwest conditions, many homeowners find the total cost of ownership closer than the upfront price difference suggests — and the maintained appearance and reduced annual labor represent real quality-of-life value.
Both are fully capped composite. TimberTech Pro Legacy is the mid-tier step up from Fiberon Pro-Tect Advantage — it carries a 25-year product warranty and 25-year fade/stain warranty versus Fiberon's standard warranty terms. For homeowners with more budget flexibility and a longer horizon, Pro Legacy is the more durable choice. For standard residential deck builds where the budget doesn't stretch to TimberTech, Fiberon provides genuine capped composite performance at a lower entry price.
AZEK is cellular PVC — no wood fiber, complete moisture immunity, 50-year limited warranty. It is the premium tier for maximum-longevity and high-moisture applications. Fiberon is capped composite — genuinely low-maintenance, but not at the AZEK performance level. The right choice between them depends entirely on the exposure profile, budget, and how long the homeowner plans to be in the home.
We're authorized for both brands across the full composite and PVC range. If Fiberon is the right answer for your budget and project, we say so. If your project warrants TimberTech AZEK, we explain why. We don't steer homeowners into higher-margin products — we match the product to the project.
Composite deck boards perform correctly when the framing underneath is built to code — properly spaced joists, appropriate ventilation, correct flashing at the ledger. We build the framing right because that's what makes composite or PVC decking perform to its warranty over the long term.
We handle permits on every project that requires them — structural drawings, inspections, engineering where needed. Clark County, Portland, Camas, Battle Ground, Ridgefield, and other jurisdictions each have their own permit requirements. We navigate them without burdening the homeowner with the process.
Our deck building service covers Southwest Washington and the Portland Metro. We spec Fiberon and TimberTech based on each project's budget and exposure requirements.
Pro-Tect Advantage is a fully capped composite — wood fiber and polymer composite core with a protective polymer cap on all four sides. The cap prevents moisture absorption that caused first-generation uncapped composite to fail in Pacific Northwest conditions. It's Fiberon's entry-level capped product, delivering genuine low-maintenance performance at an accessible price point compared to higher-tier composite and PVC options.
Both are fully capped composite manufacturers. Fiberon Pro-Tect Advantage is the entry-level tier; TimberTech Pro Legacy is the mid-tier upgrade; TimberTech AZEK is premium cellular PVC. We are authorized for both brands. For homeowners on tighter budgets upgrading from pressure-treated wood, Fiberon provides genuine capped composite performance. For projects with more flexibility, TimberTech Pro Legacy or AZEK may be a better match. We make specific recommendations at the estimate.
Annual or semi-annual cleaning with soap and water to remove organic buildup. No staining. No sealing. No board replacement from rot. For heavily shaded decks where buildup is heaviest, semi-annual cleaning keeps the surface clean. This is a convenience task, not a structural maintenance requirement — fundamentally different from the pressure-treated wood annual treatment cycle.
Fiberon is the right choice when the primary goal is upgrading from pressure-treated wood without the budget for TimberTech's lines, and the deck profile is standard residential exposure (not heavily shaded water-adjacent, not a 50-year planning horizon). AZEK is right for maximum-longevity applications, lakeside or heavily shaded decks, or premium homes where the cellular PVC investment is appropriate. We walk through the comparison at every deck estimate.
