How Much Does a Composite Deck Cost in Central PA?

For homeowners who want the look of wood without the upkeep, composite decking has become the go-to choice. It’s durable, low-maintenance, and available in a wide range of colors and finishes. Additionally, it opens up a world of options and possibilities to make your outdoor space truly shine.

But what does it actually cost to build a composite deck in Central PA?

Most composite decks in our area range from $25,000 to $45,000, depending on size, design, and features. While that’s a jump from pressure-treated lumber, many homeowners see it as a worthwhile long-term investment.

What Impacts the Cost?

Just like with wood, the final price of a composite deck depends on a few big factors:

• Size – Larger decks increase both material and labor costs.

• Material brand & line – Trex, TimberTech, and other brands offer multiple tiers, from entry-level to premium capped composites.

• Height & structure – Raised or multi-level decks add framing and labor complexity. Believe it or not, ground level decks can also come with their own challenges! Read more about them here.

• Railings – Composite or aluminum railings pair well with the decking but add to the cost.

• Stairs & custom features – Built-in benches, planters, lighting, or curved designs push costs upward.

Cost Breakdown Example

Here’s a look at typical composite deck projects in Central PA:

• 12x16 deck, entry-level composite, simple railings → $25,000–$30,000

• 16x20 deck, mid-tier composite, one staircase, aluminum railings → $30,000–$40,000

• 20x30 deck, premium composite, multiple features & lighting → $45,000–$60,000+

The Pros of Composite Decking

• Low maintenance – No staining, sealing, or painting required.

• Long lifespan – With proper care, composite decks often last 25+ years.

• Resistant to rot and insects – Won’t warp or decay like natural wood.

• Great aesthetics – Available in a variety of colors, grain patterns, and finishes.

The Cons to Consider

• Higher upfront cost – Typically 30–50% more than pressure-treated lumber.

• Heat retention – Composite can get warmer underfoot in direct sun. If that's something you're concerned about, check out 100% PVC decking options.

• Less natural look/feel – While modern options are very realistic, it’s still not real wood.

Is Composite Right for You?

Composite decking is best for homeowners who:

• Want a beautiful, modern deck with minimal upkeep.

• Plan to stay in their home long-term.

• Value the durability and warranty protection over upfront savings.

If your priority is keeping the initial price tag down, you might want to check out pressure-treated lumber instead. See our guide here: How Much Does a Pressure-Treated Deck Cost?
