Trex Composite Lines
Choose the right Trex line for your home.
Trex offers several decking lines at different price points — each fully capped and engineered for Pennsylvania's freeze-thaw winters and humid summers. We'll bring samples and help you pick the line, color, and railing that fit your budget and style.
Trex Transcend & Transcend Lineage
Trex's flagship line — the richest, most realistic wood-grain colors with heat-mitigating technology that keeps boards cooler underfoot. Backed by a 50-year limited residential warranty.
Trex Enhance (Naturals & Basics)
A lighter, value-focused composite with the same scratch, fade, and stain resistance in a streamlined palette. Carries a 25-year limited residential fade & stain warranty.
Trex Select
The middle tier — durable, low-maintenance boards in classic earth tones with a 35-year limited warranty. A great balance of price and premium feel.
TimberTech (AZEK & PRO)
We also build with TimberTech's capped polymer and composite lines — including fully PVC AZEK boards for maximum moisture and stain resistance with warranties up to 50 years.

Warranty you can count on
Every Trex line carries a robust limited residential warranty — 25 years on Enhance, 35 on Select, and up to 50 years on Transcend and TimberTech AZEK. These cover fade, stain, and material defects, so your deck looks great for decades. We install to Trex specifications so your warranty stays fully valid.
What a Trex deck costs
Most Trex composite decks in Bucks County run between $20,000 and $70,000+, depending on size, the line you choose, railings, lighting, and site conditions. Composite costs more up front than wood but saves thousands in maintenance over its lifetime — no annual staining, sealing, or board replacement. We provide a detailed, transparent estimate after an on-site visit.
Have Questions?
Answers for local homeowners.
How much does a Trex composite deck cost in Bucks County?
Trex and TimberTech composite decks typically cost more up front than wood — generally $20,000 to $70,000+ depending on size, line (Transcend, Enhance, etc.), railings, and lighting — but they save money long term with virtually no maintenance and a long warranty.
Is composite decking worth it compared to wood?
For most homeowners, yes. Composite resists fading, staining, scratching, mold, and rot, never needs sanding or sealing, and carries warranties up to 25–50 years. You spend more once and almost nothing on upkeep afterward.
What composite brands do you install?
We build primarily with Trex and TimberTech, the two leading composite systems, and can match the exact line, color, and railing system you prefer. We're happy to show samples during your consultation.
Does composite decking get hot in the sun?
Modern composites with heat-mitigating technology stay noticeably cooler than older boards, but any decking warms in direct sun. We'll recommend lighter colors and shade strategies — like pergolas or covered roofs — where it matters.
How long does it take a Trex deck builder to complete a project?
Most Trex deck builds in Bucks County take 2 to 4 weeks from permit approval to final walkthrough, depending on size, complexity, and weather. Smaller decks may finish sooner; multi-level or covered designs with lighting and railings can take a bit longer. We keep you updated at every stage.
Does a Trex deck increase home value?
Yes — a well-built composite deck consistently ranks among the top outdoor improvements for return on investment. Buyers love the low-maintenance appeal, and a professionally installed Trex deck with clean railings and lighting adds real curb appeal and usable living space.
Can you build a Trex deck over an existing wood deck frame?
Sometimes. We inspect the existing frame for rot, proper fasteners, and code compliance before reusing it. If the framing is solid and meets current span requirements, we can resurface it with new Trex decking and railings — a cost-effective way to upgrade without a full rebuild.
How do you clean and maintain a Trex deck?
Trex decks need almost no maintenance — just soap, water, and a soft-bristle brush a few times per year. Unlike wood, there's no sanding, staining, or sealing. Mildew from shaded areas rinses off easily, and the shell resists most spills and stains.
What colors and styles does Trex decking come in?
Trex offers dozens of colors across Transcend, Enhance, and Select lines — from rich tropical hardwood looks to subtle earth tones and modern grays. Grain patterns range from subtle to pronounced, and matching fascia, railings, and lighting complete the look. We bring full samples to your consultation.
Is Trex decking slippery when wet?
Trex boards are engineered with textured, slip-resistant surfaces that perform well in rain and snow. The embossed grain provides traction underfoot, making Trex a safe choice for pool decks, stairs, and Bucks County's wet seasons.
Is Trex the same as composite decking, or is it different?
Trex is composite decking — it's the original and most recognized brand in the category. However, not all composite decking is Trex. Trex boards are fully capped on all four sides with a protective polymer shell, while some budget composites are only capped on top or use lower-density core materials. When homeowners search 'Trex vs composite deck,' what they're really asking is whether Trex outperforms generic or lower-tier composite brands. In our experience, Trex delivers better fade resistance, a stronger warranty, and more realistic wood-grain aesthetics than entry-level alternatives.
Does Trex fade less than other composite decking brands?
Yes — Trex Transcend and Transcend Lineage carry a 50-year limited residential fade & stain warranty, which is among the longest in the industry. Lower-tier composite brands may fade noticeably after just a few summers of direct sun. Trex's four-sided capping and advanced color-mixing technology lock in pigments deeper than surface-level coatings, so your deck stays vibrant through Bucks County's hot, humid summers.
How does Trex maintenance compare to generic composite decking?
Both Trex and quality composite decking are low-maintenance compared to wood, but Trex requires even less attention over time. Because Trex boards are fully capped, dirt, pollen, and mildew sit on the surface rather than soaking in. Budget composites with partial capping or porous cores can trap moisture and develop staining or mold in shaded areas. A quick soap-and-water rinse is usually all a Trex deck needs — no pressure washing, no deck cleaners, no special treatments.
What is the lifespan of Trex vs other composite decks?
Trex decks are engineered to last 25 to 50 years depending on the line — Enhance carries a 25-year warranty, Select 35 years, and Transcend up to 50 years. Generic composite brands often top out at 20 to 25 years with shorter fade warranties. When you compare total cost of ownership, the longer lifespan and minimal maintenance of Trex typically deliver better long-term value than cheaper composite alternatives that may need board replacement or refinishing sooner.
