Let’s Talk Numbers (Honestly)
If you’re considering adding a custom deck to your home, one of the first questions you’re likely asking is:
“How much does a deck cost?”
It’s a fair question – but the truth is, the answer depends on several key factors. That’s why you’ll see wildly different pricing ranges online, from $5,000 DIY builds to $100,000+ luxury outdoor spaces.
At Lakeside Decking, we focus on high-end, low-maintenance outdoor living spaces built with premium materials like TimberTech composite and PVC decking, and steel framing. So let’s break down what actually drives cost — and what kind of investment you should expect for a custom deck in 2026.
The #1 Cost Factor: Size
Simply put: more square footage = more cost.
A 200 square foot deck is in a completely different category than a 600 square foot deck – even with the same layout and materials. Here’s why size has the biggest impact:
- More framing, posts, and footings
- More decking boards and railing
- More labor and time on site
- Greater design complexity (longer spans, load limits, etc.)
Typical Price Range For a Simple Composite Deck:
- Small (200–300 sq ft): $35,000–$50,000
- Medium (350–500 sq ft): $50,000–$75,000
- Large or complex (600+ sq ft): $85,000–$125,000+
Other Factors that Impact Your Deck Investment
While size is the biggest factor, it’s not the only one. Here’s what else contributes to cost:
1. Decking Material
We exclusively use composite and PVC decking from TimberTech — not wood — because it offers exceptional durability, color retention, and minimal maintenance. Higher-end boards with realistic textures or advanced coatings carry a premium price, but last far longer.
2. Decking Color Line
We’ve already selected the industry-leading decking board brand for you, but that doesn’t mean you’re left without options! TimberTech offers eleven color lines across two product types (Advanced PVC and Composite), all with different price points. While this doesn’t impact price quite as much as size, color line still plays a big part in the overall cost of your deck.
3. Framing Material
We offer KDAT lumber, steel, composite, and aluminum framing options. KDAT is cost-effective and stable, while steel, composite, and aluminum provide superior durability, precision, and long-term performance — with higher upfront investment.
4. Railing Systems
Your choice of railing (aluminum, cable, and glass options) greatly affects both aesthetics and cost. Premium railings can account for a significant portion of the overall budget.
5. Elevation & Site Conditions
- Elevated decks require more structural work
- Hillside or hard-to-access sites increase labor
- Existing deck demo or site prep adds to cost
6. Design Complexity
Details like picture-framed borders, inlays, multi-level designs, and curved edges enhance the look — but also increase material waste and installation time.
6. Add-ons & Enhancements
Looking to go beyond just a deck? These popular upgrades add cost — and major value:
- Pergolas & shade structures
- Integrated lighting & wiring
- Built-in seating or planters
- Fire pits & outdoor kitchens
- Patios & hardscaping connections
