Top Composite Brands & Pricing

Decked Out Builders is a TimberTech Platinum Certified Contractor and works with the best composite decking brands in the industry. Here's how the leading brands compare on price and quality.

TimberTech AZEK
$50–$70 / sq ft installed
Deckorators Voyage
$50–$60 / sq ft installed
TimberTech Reserve
$40–$45 / sq ft installed
Fiberon Promenade
$36–$44 / sq ft installed
TimberTech Terrain
$30–$37 / sq ft installed
MoistureShield Pro
$22–$36 / sq ft installed
Wolf Serenity
$20–$30 / sq ft installed
Our Recommendation: TimberTech AZEK is our most-requested premium board — a full-PVC construction that stays cooler underfoot, resists scratching, and carries a truly transferable lifetime warranty against fading and staining. TimberTech is the top choice for value in the capped composite category. Both are backed by some of the strongest warranties in the industry.

Factors That Affect Your Price

Your final project cost is shaped by a combination of choices. Understanding these factors helps you make smart trade-offs and plan your budget with confidence.

📐

Deck Size & Square Footage

The most direct cost driver. More square footage means more materials and labor. Fixed costs (permits, footings, mobilization) dilute over larger decks, lowering per-sq-ft costs.

200 sqft ≈ $25–$45k · 500 sqft ≈ $55–$90k
🏗️

Deck Height & Elevation

Elevated and second-story decks require significantly more structural framing, beams, posts, and footings. Ground-level decks are the most cost-effective to build.

Ground level: base · Elevated: +25–50% · 2nd story: +40–65%

Composite Material Grade

The board you choose is the biggest material cost swing. Upgrading from entry-level to premium AZEK can add $10–$18 per sq ft — but it pays off in longevity and warranty coverage.

Entry: $3–$5/LF · Premium: $6–$10/LF
🪜

Stairs, Landings & Levels

Each stair flight adds significant cost. Wide stairs, angled landings, or multiple stair locations multiply this quickly. Multi-level decks are more complex and costly.

Standard: $4,200–$10,400 · Wide/complex: $8,500–$25,000
🏡

Railing System

Railings are a major visual and cost element. Basic aluminum balusters are affordable; cable and glass panel systems command a significant premium but look stunning.

Basic aluminum: $75–$90/lft · Cable/glass: $100–$160/lft
🔀

Deck Shape & Complexity

Rectangular decks are the most efficient to build. Angled cuts, curves, picture frames, and inlays increase material waste and labor, adding 15–35% to the board cost.

Rectangle: base · Complex pattern/curves: +15–35%

15-Year Cost of Ownership Comparison

The upfront cost of composite is higher than pressure-treated wood — but over 10 years, composite almost always wins. Here's why the math favors composite for most homeowners.

Cumulative 15-Year Cost of Ownership
Based on a 250 sq ft deck · Composite $24k initial + $40/yr · PT Wood $17k + $750/yr · Cedar $21k + $750/yr · PT Wood crosses composite ~Year 10
15-Year Cost of Ownership — 250 sq ft Deck (Decked Out Builders Real Data)

Cost FactorCompositePressure-Treated WoodCedar
Initial Build Cost$24,000$17,000$21,000
Annual Maintenance Cost~$40/yr (hose rinse)~$750/yr (stain/seal)~$750/yr (stain/seal)
Total Maintenance Over 15 Yrs~$600~$11,250~$11,250
Deck Replacement at 15 yrs?No — 25–50 yr lifespanApproaching end of lifeHeavy maintenance needed
15-Year Total Cost$24,600 ✓ Lowest$28,250$32,250
The Real Numbers: PT wood starts $7,000 cheaper than composite — but with $750/year in staining and sealing, it crosses composite's total cost around Year 10. By year 15, composite is the clear winner at $24,600 total vs. $28,250 (PT wood) and $32,250 (cedar) — and composite still has 10–35 more years of life left.

Why Is Composite Decking So Low-Maintenance?

Composite decks require virtually no annual maintenance beyond a simple hose rinse and occasional mild soap wash. The smooth, non-porous surface of capped and full-PVC composite boards prevents algae and mold from taking hold, reducing the need for chemicals and scrubbing.

With wood decks, skipping even one staining cycle can lead to cracking, splintering, graying, and premature board degradation. With composite, there's nothing to skip — it's maintenance-free by design.

We serve Barrington, Lake Zurich, South Barrington, Deer Park, Kildeer, Lake Barrington, Crystal Lake, Algonquin, Palatine, Hoffman Estates, and surrounding communities.


ROI & Home Value

↓ All figures below are based on 250 sq ft deck averages

A composite deck consistently ranks among the highest ROI home improvement projects. According to Remodeling Magazine's annual Cost vs. Value Report, composite deck additions recover 63–72% of their cost at resale — and in high-demand suburban markets like Barrington and Lake Zurich, that number can climb higher.

Composite decks outperform wood decks at resale because buyers perceive low-maintenance as a tangible financial benefit. A 10-year-old composite deck that looks nearly new is far more appealing than a weathered wood deck that needs immediate staining and repair before move-in.

Frequently Asked Questions

How much does a composite deck cost from Decked Out Builders?
+
Our minimum projects start at $20,000, but the majority of our projects fall in the $45,000–$65,000 range for a complete composite deck with premium materials, railings, stairs, and lighting. Full outdoor living spaces with pergolas, screened porches, or outdoor kitchens typically run $65,000–$150,000+. We specialize in high-end builds using only top-tier materials — we do not offer wood decks, basic maintenance, or deck repairs.
What composite decking brands do you use?
+
We are a TimberTech Platinum Certified Contractor and primarily work with TimberTech AZEK. View all our brand partners on our brochures page.
How long does composite decking last?
+
Quality capped composite decking lasts 25–30+ years with minimal maintenance. TimberTech AZEK (full PVC) boards carry a lifetime warranty against fading, staining, and structural issues. The substructure (pressure-treated framing, posts, footings) typically lasts 30+ years when properly built and maintained. Compare this to pressure-treated wood decks that need replacement in 10–15 years, or cedar that requires annual oiling and begins to show wear within 5–8 years without proper maintenance.
Do you build wood decks?
+
No. Decked Out Builders specializes exclusively in composite decks, pergolas, screened porches, covered porches, outdoor kitchens, and full outdoor living spaces. We do not offer wood decks, basic deck maintenance, or deck repairs. If you're comparing composite vs. wood, we're happy to walk you through the full cost-of-ownership difference so you can make an informed decision.
How much maintenance does a composite deck require?
+
Composite decking is designed to be virtually maintenance-free. Annual upkeep typically consists of nothing more than a rinse with a garden hose and occasional wash with mild soap to remove pollen, dust, and organic debris. You never need to sand, stain, seal, or paint composite decking. Some boards may develop surface mold in heavily shaded or humid environments — this washes off easily with a composite-safe deck cleaner. TimberTech AZEK in particular has exceptional mold and moisture resistance as a full-PVC board.
Do I need a permit to build a composite deck?
+
In almost every municipality in the northwest Chicago suburbs — yes. Permits are required for decks attached to the house, elevated more than 30 inches, or over a certain square footage threshold (often 200 sq ft). Permit fees typically range from $400–$1,500 depending on your municipality and project scope. Decked Out Builders handles all permit applications and municipal inspections on every project we build. Building without a permit can result in fines, forced removal, and serious complications when selling your home.
How long does it take to build a composite deck?
+
A standard single-level composite deck (300–400 sq ft) typically takes 5–12 business days of active construction once permits are approved. Add-ons like pergolas, screened porches, or outdoor kitchens extend this to 2–4 weeks. Permit approval in our service area typically takes 2–4 weeks, so total project timeline from contract to completion is usually 4–8 weeks depending on permit and scheduling.
What areas do you serve?
+
Decked Out Builders serves the northwest Chicago suburban area including Barrington, Lake Zurich, South Barrington, Deer Park, Kildeer, Lake Barrington, North Barrington, Inverness, Hawthorn Woods, Long Grove, Buffalo Grove, Palatine, Hoffman Estates, and surrounding areas. Check our service areas page or reach out directly to confirm we service your area.
What financing options are available?
+
We work with financing partners to help make your outdoor living project more accessible. Options include home improvement loans, home equity financing, and flexible payment plans. Financing terms, rates, and qualifications vary — contact us for details and we'll connect you with the right options for your situation.
What's included in your warranty coverage?
+
Our projects are backed by both our workmanship warranty and the manufacturer's material warranty. TimberTech AZEK offers a lifetime fade and stain warranty and a 30-year structural warranty. Our workmanship warranty covers the quality and installation of all components we build. See full details on our warranties page.
