Why Composite Decking Makes Sense in Central Illinois
Composite decking — boards made from a combination of wood fiber and plastic — was designed to solve the maintenance problems that come with traditional wood decking in climates like Peoria’s. Central Illinois puts outdoor wood through repeated freeze-thaw cycles every winter, high UV exposure in summer, and significant seasonal humidity swings. Wood decking handles all of this acceptably, but it requires ongoing attention: staining or sealing every 2–3 years, board replacement as individual boards fail, and periodic refinishing to maintain appearance.
Composite changes that equation. Premium composite products like Trex Transcend or TimberTech AZEK are engineered to resist moisture absorption, resist fading under UV, and maintain structural integrity through temperature extremes. The result is a deck surface that looks essentially the same in year 15 as it did in year 2 — without any staining or sealing cycles.
Composite Products We Install
We install products from the leading composite manufacturers. The right choice depends on your budget, aesthetic goals, and how you plan to use the space:
- Trex Transcend — Trex’s premium line. Excellent fade and stain resistance. Realistic wood-grain look. Widely available in Central IL, well-supported warranty program.
- Trex Select & Enhance — Mid-range Trex options. More affordable entry point with solid performance for the Central IL climate.
- TimberTech AZEK — Capped cellular PVC (not composite in the traditional sense). Excellent moisture resistance and the best-in-class performance for very wet or shaded installations.
- TimberTech Pro & Reserve — Composite lines from TimberTech. Good performance at a slightly lower price point than AZEK.

|---|---|---|
| Upfront Cost | Lower — $15–22/sq ft installed | Higher — $30–55/sq ft installed |

| Appearance Over Time | Grays, checks, may warp | Holds color and surface texture well |
| Freeze-Thaw Performance | Good if maintained | Excellent — engineered for it |
| Splinters / Rough Surface | Yes, especially as it ages | No — smooth surface throughout |
| Barefoot Comfort | Moderate | Better — no splinters or checks |
| Lifespan (well-maintained) | 15–25 years | 25–35 years |
| Best For | Budget-first, happy to maintain | Low maintenance, long-term value |

What Composite Decks Cost in Peoria, IL
Composite decking costs more upfront than pressure-treated wood. For most Central Illinois homeowners, the math shifts over a 10-year window when you factor in stain, sealer, labor, and board replacement costs for a wood deck. Here are realistic ranges for installed composite decks in the Peoria area in 2026:
- Small composite deck (10x12): $10,000–$16,000
- Mid-size composite deck (16x20): $26,000–$40,000
- Large or multi-level composite: $45,000–$80,000+
Product choice affects price significantly — Trex Select is meaningfully less expensive than AZEK. We walk through all options when we quote, so you can choose the right balance of performance and cost for your situation.
What’s Included in a Composite Deck Installation
Same structural build process as any deck we install: properly-sized footings to frost-line depth, PT framing throughout (framing is still wood regardless of the decking surface), and then composite decking on top. The difference is in the surface product: composite boards, concealed fastening systems (we prefer hidden fasteners on composite for a cleaner look), and composite railing systems if requested.
