Fiberon Deck Cost by State

From $38 to $95 per square foot installed, with the sweet spot at Sanctuary, $58 per square foot. On a 16x20 deck at 320 square feet, that is roughly $12,160 for a Paramount build, $18,560 for Sanctuary, and up to $30,400 at the top of the range. The headline band matches Trex almost exactly, but the ladder inside it is arranged differently and that is where the value sits: Paramount at $38 is cellular PVC rather than composite, and Sanctuary at $58 carries a 50-year stain and structural warranty — longer than Trex offers on any line at any price. As with every brand, material cost is roughly national and labour is not; multiply by your state's multiplier, which runs from about 0.92x in the South to 1.28x on the West Coast, using the table below.

On the boards, yes, and on warranty the premium line is better. Fiberon Sanctuary carries 50 years on stain and structural at $58 per square foot installed; Trex's longest coverage is 25 years fade and 25 structural, with lifetime structural on Transcend and Signature. Sanctuary has also rated at or near the top of independent durability testing. Where Trex wins is not the product: it is availability and recognition. Home Depot stocks Trex in depth, so a short order is solved the same day, and a buyer looking at your house in ten years will know the name. Fiberon usually means a special order for top-ups and a lead time that matters mid-build. If you value the warranty and the price, Fiberon is the better buy; if you value being able to walk into a store on Saturday, Trex is.

Sanctuary, for most builds, because that is where the warranty jumps. Fiberon's ladder does not climb evenly: Paramount at $38 per square foot carries 25 years, Promenade at $48 carries 30, and Sanctuary at $58 carries 50 years on stain and structural — a much larger step in coverage than in price. Concordia at $68 sits above it, but what the extra buys is appearance rather than protection, since the warranty does not improve further. The exception is a wet or coastal site on a tight budget, where Paramount deserves a look for a reason that has nothing to do with its price tier: it is cellular PVC rather than capped composite, so it does not absorb water at all — a property competitors reserve for lines costing $70 and up.

Yes, and it is the most unusual thing in Fiberon's line-up. Paramount is cellular PVC at $38 per square foot installed, a price point where Trex Enhance at $38 and TimberTech Edge Prime+ at $42 are both capped wood-fibre composites. The practical consequence is that Paramount does not absorb water at all, which matters beside a pool, in a wet climate, or within a few miles of saltwater — conditions where a composite depends entirely on its cap staying intact. The trade-offs are honest ones: it carries Fiberon's shortest warranty at 25 years, the colour range is narrower than the composite lines, and PVC does not feel like wood underfoot in the way a wood-fibre board does. For a budget deck in a demanding environment, though, it is a combination that is genuinely hard to find elsewhere.

About 30 years in service, between Trex's 28 and AZEK's 35 — and on the premium line the warranty runs longer than the expected life, at 50 years stain and structural on Sanctuary. As with any composite, the boards will outlast the structure underneath unless the framing is specified to match: pressure-treated framing has a 15 to 25-year service life in ground-contact conditions, and the ledger connection to the house is the component that actually fails on decks of every material and price. Two habits protect the investment. Register the warranty within the manufacturer's window, which needs board serial numbers the contractor must hand over at install. And wash the deck twice a year, because a stain warranty covers pigment failure, not the grey biofilm that accumulates on every horizontal surface outdoors.
