How Much Does a Deck Cost in Peoria IL in 2026?

The most common question we get: How much is this going to cost? It’s a fair question and one most contractors dance around. We don’t. Here’s an honest breakdown of what decks actually cost in Peoria, Illinois in 2026 — based on what we quote and build, not national averages from home improvement content farms.

The most important thing to know: there is no accurate answer without an on-site assessment. Size, height, material, site conditions, and permit requirements all affect the final number significantly. These ranges get you in the ballpark.

What Drives Deck Cost in Peoria, IL

Before getting to the numbers, here’s what actually moves the price:

• Square footage — bigger deck, more material and labor
• Decking material — PT wood vs. composite vs. cedar changes cost significantly
• Height and complexity — raised decks require bigger posts and more structural work; multi-level costs more than flat
• Permits — required for most projects over 200 sq ft in Peoria area; factor in permit fees and inspection scheduling
• Railing and stairs — composite or aluminum railings cost more than wood; more stairs = more cost
• Site conditions — sloped yards, tight access, or demo of an existing deck all add cost

Pressure-Treated Wood Deck Costs in Peoria

PT wood is the most cost-effective decking material. Standard framing is also PT regardless of what goes on top. For a straightforward PT deck in the Peoria area in 2026:

Size	Style	Installed Range
10 x 12 (120 sq ft)	Ground-level, no railing	$6,000 – $9,500
12 x 16 (192 sq ft)	Ground-level with railing	$9,000 – $14,000
16 x 20 (320 sq ft)	Standard raised, railing + stairs	$14,000 – $22,000
20 x 24 (480 sq ft)	Larger raised with stairs	$20,000 – $32,000
Multi-level	Two elevations, full railing	$28,000 – $55,000+

Composite Deck Costs in Peoria

Composite costs more upfront — typically 50-100% more than the equivalent PT build. The trade-off is very low long-term maintenance. For Trex or TimberTech composite in the Peoria area:

Size	Style	Installed Range
10 x 12 (120 sq ft)	Ground-level, no railing	$10,000 – $16,000
16 x 20 (320 sq ft)	Standard raised, railing + stairs	$26,000 – $40,000
20 x 24 (480 sq ft)	Larger raised with stairs	$38,000 – $58,000
Multi-level	Two elevations, composite railing	$50,000 – $85,000+

Product choice within composite also moves the number — Trex Select is meaningfully less expensive than Trex Transcend or TimberTech AZEK. We walk through all options when we quote.

What’s NOT Included in These Ranges

• Demo and hauling of an existing deck (add $800–$2,500 depending on size)
• Landscaping disturbance or yard restoration
• Pergola, gazebo, or overhead structure additions
• Lighting, electrical, or built-in outdoor kitchen work
