How Much Does a Deck Really Cost in South Jersey (2025 Guide)

If you’re thinking about building a deck this year, one question always comes first — how much does it actually cost? The truth is, deck prices in South Jersey vary depending on the size, materials, and design details.

At C-JAM Construction, we’ve built hundreds of decks across Gloucester, Camden, and Salem Counties — and we’re breaking down what real homeowners spend in 2025.

Average Deck Cost in South Jersey (2025 Estimates)

Deck Type	Typical Size	Price Range
Pressure-treated wood	12’x16’	$8,000 – $12,000
Trex composite	12’x16’	$14,000 – $20,000
Larger composite deck (16’x20’)		$20,000 – $28,000+
Premium multi-level design		$30,000 – $50,000+

💡 These ranges include materials, framing, rails, and labor — but not extras like lighting, built-in seating, or permits.

What Affects Deck Pricing

Every deck project is unique, but most costs fall into these five categories:

1. Material Choice – Trex and other composites cost more upfront but save thousands in long-term maintenance.

2. Size & Shape – The bigger and more complex your deck, the more framing, rails, and footings you’ll need.

3. Site Conditions – Uneven yards, pool installations, or tight access areas can raise labor costs.

4. Rail Style – Vinyl, aluminum, and glass rails all add cost compared to standard wood.

5. Local Permits & Inspections – Each NJ township has its own requirements, typically $100 – $500 per permit.
