Choosing a composite deck brand is the single biggest decision most GTA homeowners make on a deck project, and it shapes how the surface looks, feels underfoot, and holds up through fifteen Ontario winters. Trex, TimberTech and Fiberon dominate the shortlist for good reason, but they are not interchangeable. Here is an honest, builder's-eye comparison for 2026, based on what we install and warranty every season across Toronto and the surrounding region.
Capped composite vs. capped polymer: the difference that matters
Before comparing brands, it helps to understand the two core technologies. Almost every premium board sold today is capped, meaning a hard protective shell is bonded around the core to resist fading, staining and scratching. What differs is the core.
Capped composite boards (Trex and Fiberon) use a core made of recycled wood fibre blended with polyethylene plastic. They feel solid and substantial, look convincingly like wood, and cost less. Capped polymer boards — TimberTech's AZEK line — contain no wood fibre at all. They are cellular PVC, so they are lighter, absorb almost no moisture, stay cooler in direct sun, and resist scratching better. That performance comes at a higher price. For a deeper look at how composite stacks up against traditional lumber, see our guide to composite versus wood decks in the GTA.
The three brands at a glance
| Brand | Material type | Warranty | Price tier | Best for |
|---|---|---|---|---|
| Trex | Capped composite (recycled wood + polyethylene) | 25-year fade & stain; 25-year limited residential | Mid | Proven value and the widest local availability |
| TimberTech / AZEK | Capped polymer (cellular PVC); also capped composite lines | Up to 30-year fade & stain; up to 50-year limited (AZEK) | Premium | Best heat, scratch and moisture performance |
| Fiberon | Capped composite (wood fibre + HDPE) | 25-year fade & stain; up to 50-year limited residential | Mid | Rich colour range at a competitive price |
| Deckorators | Mineral-based composite (MBC) | 25-year fade & stain; up to 50-year structural | Mid to premium | Pool decks, docks and wet, ground-contact areas |
Trex: the dependable default
Trex is the most recognized composite name in North America, and its Transcend and Enhance lines carry a 25-year fade and stain warranty. The capped composite construction handles Ontario freeze-thaw cycles well, resists mould, and never needs sanding or staining. Boards run slightly warmer underfoot than PVC on a hot July afternoon, and the premium lines cost as much as some entry PVC, but availability across the GTA is excellent and colour matching for future repairs is straightforward. If you want a trusted, mid-priced deck that will look good for decades, Trex is a safe choice — and it is popular enough that we maintain a dedicated Trex deck building service.
TimberTech AZEK: the performance leader
TimberTech sells both capped composite lines (PRO and EDGE) and its flagship capped polymer AZEK boards. AZEK is the board to beat on pure performance. Because it is 100% PVC, it absorbs virtually no water, stays measurably cooler in sun, and shrugs off scratches from patio furniture and dog nails better than any wood-filled composite. The wood-grain embossing on premium AZEK collections is, in our opinion, the most realistic on the market, and warranties reach up to 30 years for fade and stain with an up-to-50-year limited product warranty. The trade-off is cost: AZEK typically sits at the top of the price ladder. For a poolside or full-sun rooftop deck where heat and moisture are real concerns, it is often worth every dollar.
Fiberon: style and value
Fiberon is the quiet strong performer. Its capped composite boards deliver colour depth and multi-tonal streaking that rival more expensive brands, with a 25-year fade and stain warranty and up to a 50-year limited residential warranty on select lines. Pricing generally lands alongside Trex, sometimes a touch below, which makes Fiberon a smart pick for homeowners who want a designer look without stretching into PVC pricing. Local stock can be slightly thinner than Trex, so we confirm availability before finalizing a colour.
Don't overlook Deckorators for pools and docks
We also install Deckorators, whose mineral-based composite (MBC) uses a mineral core instead of wood fibre. The result is exceptional dimensional stability and near-zero water absorption, so the boards stay flat and are rated for wet, ground-contact and even structural applications. For a pool deck, a dock, or a low deck close to grade where standing water is a fact of life, Deckorators is frequently the most sensible board we can specify.
Realistic 2026 installed pricing in the GTA
Composite is a lifetime investment, not a cheap one. For 2026, expect these all-in installed ranges in Toronto and the GTA, including substructure, fasteners and labour:
- Entry capped composite (Trex Enhance, Fiberon Good/Better): roughly $38–$52 per square foot installed.
- Premium capped composite (Trex Transcend, Fiberon Concordia): roughly $50–$65 per square foot installed.
- Capped polymer / PVC (TimberTech AZEK): roughly $58–$78 per square foot installed.
Elevation, railing, stairs, permits and site access move these numbers, so treat them as planning figures rather than quotes. To model your own project, try our deck cost calculator, and for a full breakdown read our 2026 Toronto deck pricing guide.
How to choose the right brand for your home
There is no single "best" board — there is a best board for your yard, budget and priorities. Use these tests:
- Sun exposure: A full-sun, south-facing or rooftop deck favours cooler, lower-absorption PVC (AZEK) or mineral-based Deckorators.
- Budget: If value drives the decision, Trex or Fiberon deliver excellent performance for less than PVC.
- Water and grade: Pool surrounds, docks and low decks point toward Deckorators.
- Look: Order physical samples and view them in your own light — embossing and colour read very differently outdoors than in a showroom.
Whatever you choose, the substructure and installation matter as much as the board. A premium deck fastened over an undersized or poorly flashed frame will still fail. You can see how we build across brands in our project gallery, and learn about our full composite decking service.
Frequently asked questions
Which composite decking stays coolest in summer?
Capped polymer PVC, such as TimberTech AZEK, generally runs coolest, followed by mineral-based Deckorators. All decking warms in direct sun, so lighter colours also help meaningfully on a hot GTA afternoon.
Do composite decks handle Ontario freeze-thaw winters?
Yes. All four brands are engineered for freeze-thaw cycling and are common across the GTA. Use a plastic shovel and a calcium-chloride-free ice melt, and avoid metal blades, to keep the cap in top condition.
Is TimberTech AZEK worth the extra cost over Trex?
For full-sun, poolside or rooftop decks, the cooler surface and superior scratch and moisture resistance often justify the premium. For a shaded or mid-budget backyard deck, Trex or Fiberon usually deliver better value.
How long do these composite decks last?
With proper installation, expect 25 to 50 years of service, well beyond the pressure-treated lumber they replace. The boards will not rot, split or need staining, though the substructure should still be inspected periodically.
