Where to Buy DuxxBak Decking: Retailers, Prices & Dealer List

DuxxBak composite decking is sold at Home Depot, Lowe’s, The Deck Store Online, and through the brand’s own dealer locator, not on Amazon despite what older buying guides claim. Ordering from an unauthorized reseller can void the DuxxBak lifetime warranty, which only pays 100% for the first 10 years before declining. This guide lists every legitimate retailer, current prices per square foot, and what the warranty actually covers before you order a single board.

Where to Buy DuxxBak Decking (Amazon Is Not One of Them)

DuxxBak composite decking is not currently sold on Amazon. It is a bulky, palletized building material, and like most full-length composite deck boards, manufacturers route it through home improvement retailers and dedicated building-supply dealers instead of general marketplaces. If a listing claiming to sell “DuxxBak decking” turns up on Amazon or a third-party marketplace, treat it as a reseller of a different product, not the real thing, and verify against the brands below first.

The four legitimate ways to buy it:

Retailer	What You’ll Find	Best For
Home Depot	In-stock boards plus buy-online-pickup-in-store	Fast local pickup
Lowe’s	Boards, in-store samples, price-match on identical items	Comparing DuxxBak against other composite brands in person
DuxxBak Dealer Locator (duxxbakdecking.com/find-a-dealer)	Full color and profile lineup, contractor and bulk pricing	Ordering enough matched boards for a whole deck build
The Deck Store Online / American Pole & Timber	Ships nationwide, phone support	Areas with no local Home Depot or Lowe’s stocking DuxxBak

Before ordering from any dealer that isn’t Home Depot, Lowe’s, or a name on the official DuxxBak dealer locator, call the manufacturer directly (1-877-804-0137) and confirm the seller is authorized. That single call is what keeps a warranty claim valid later.

How Much Does DuxxBak Decking Cost Per Square Foot?

DuxxBak decking is a composite deck board that typically runs $9 to $15 per square foot for material only, with Home Depot’s listed board pricing working out closer to $17.71 to $17.72 per square foot depending on color and profile. Installation is not included in any of those figures and generally adds another $4 to $9 per square foot in labor, since DuxxBak’s tongue-and-groove interlock takes a slightly different technique than face-screwed boards.

Cost Factor	Typical Range
Material, general retail/dealer pricing	$9-$15 per sq ft
Material, Home Depot listed pricing	$17.71-$17.72 per sq ft
Installation labor (material not included)	+$4-$9 per sq ft

If that range is more than your budget allows, compare it against pressure-treated lumber pricing before committing to composite. Pressure-treated boards cost less upfront but need repeat staining and sealing that DuxxBak is designed to skip entirely.

Is DuxxBak the Same Brand as Green Bay Decking?

DuxxBak is a composite decking brand manufactured by Duralight Plastics that was previously sold under the name Green Bay Decking until a 2019 rebrand. The board construction, the tongue-and-groove water-shedding channel, and the underlying manufacturer did not change, only the brand name did, so a Green Bay Decking board from before 2019 and a current DuxxBak board of the same profile are the same product line. This matters when you’re matching replacement boards or checking warranty paperwork on an older deck.

DuxxBak Warranty: What’s Actually Covered

DuxxBak backs its decking with a lifetime limited warranty against structural failure from manufacturing defects, but the payout isn’t flat for the full “lifetime.” Coverage runs at 100% for the first 10 years, then steps down on a straight-line depreciation basis through year 25.

“100% coverage is available only for the first ten years of ownership, then coverage decreases on a straight-line depreciation basis until the 25th year.”

— DuxxBak limited warranty terms

Real-world claims reported to the Better Business Bureau show the practical side of this: owners who found cracked boards or a puncture years into ownership described slower-than-expected responses working through a warranty claim. Two things improve those odds: buying only from an authorized retailer or dealer (see the list above) and keeping the original purchase receipt, since an unverifiable purchase source is the fastest way for a legitimate claim to get delayed.

DuxxBak Colors, Profiles, and Lengths Available

DuxxBak decking ships in two board profiles under the same brand: the standard Dekk line and the solid-edge I.Dekk line, across roughly a dozen color options ranging from light sand tones to dark walnut and rustic red. Boards come in 12-foot, 16-foot, and 20-foot lengths, all using the same tongue-and-groove interlock that creates the brand’s signature water-shedding channel between boards.

Not every retailer stocks the full color range. Home Depot and Lowe’s typically carry the 3 to 5 best-selling colors in each region, while the official dealer network and specialty suppliers are more likely to have the complete lineup on hand or available to special-order. If you need boards from two different retailers to finish a project, buy an extra board from your first source and take it with you when color-matching at the second, since dye lots can vary slightly between production runs even within the same named color.

Common Mistakes When Buying DuxxBak Decking

• Assuming Amazon carries it: as covered above, it doesn’t. Searching Amazon first wastes time and risks landing on a mislabeled or unrelated product.
• Buying from an unverified online seller: if a listing isn’t Home Depot, Lowe’s, or a name on the official dealer locator, call DuxxBak’s corporate line first. An unauthorized purchase source is the most common reason a later warranty claim gets denied or delayed.
• Ordering board colors from different production runs without a sample in hand: composite decking dye lots shift slightly over time, and a color that matched a photo online can read differently in person.
• Pricing the project on material alone: the $9 to $17.72 per square foot range above is material only. Skipping the $4 to $9 per square foot installation estimate is the single biggest reason DIY budgets for composite decks run short.
• Losing the receipt: DuxxBak’s warranty depreciates after year 10 and typically requires proof of purchase from an authorized source to process a claim at all.

Checking DuxxBak Stock at a Physical Store

Home Depot and Lowe’s carry DuxxBak in most regions, but store-level stock varies by color and board length, so check the retailer’s website inventory tool for your specific store before driving over. If your nearest store shows zero stock, use the DuxxBak dealer locator to find a specialty lumberyard or deck supplier instead. Specialty suppliers like composite and PVC decking dealers often carry the full color range Home Depot’s shelf space can’t fit, and staff there can special-order specific lengths or colors that aren’t sitting in a big-box aisle.

Call ahead to confirm the color and length you want are in stock at your specific store.

Is DuxxBak decking sold on Amazon?

No. DuxxBak composite decking is not sold on Amazon as of this writing. Any Amazon listing claiming to be full-length DuxxBak deck boards should be treated as a different product being mislabeled, since the brand routes sales through Home Depot, Lowe’s, and its own authorized dealer network only.

How much does DuxxBak decking cost per square foot?

DuxxBak decking material generally costs $9 to $15 per square foot, though Home Depot’s listed pricing runs closer to $17.71 to $17.72 per square foot. Add roughly $4 to $9 per square foot for professional installation, since price varies by color, board profile, and region.

Is DuxxBak the same as Green Bay Decking?

Yes. DuxxBak is the current brand name for the composite decking previously sold as Green Bay Decking before a 2019 rebrand. The manufacturer, Duralight Plastics, and the board construction stayed the same, so older Green Bay Decking boards match current DuxxBak boards of the same profile.

What does the DuxxBak warranty cover?

DuxxBak’s lifetime limited warranty covers structural failure from manufacturing defects. It pays 100% of the covered cost for the first 10 years of ownership, then decreases on a straight-line depreciation basis through year 25. Keep your original receipt from an authorized retailer, since it is typically required to file a claim.

Bottom line: skip searching Amazon for DuxxBak decking and go straight to Home Depot, Lowe’s, or the official dealer locator. Confirm the seller is authorized, budget $9 to $17.72 per square foot for material plus $4 to $9 per square foot for installation, and hold onto your receipt so the 10-year full warranty window actually protects you if a board fails.
