How Much Does a Deck Cost in Connecticut?
By Da Deck Boss LLC · Updated October 2026 · Windsor, CT
A deck in Connecticut typically costs $36 to $57+ per square foot installed, depending on material and complexity. A basic 300 sq. ft. pressure-treated deck runs roughly $10,800–$11,400 installed; the same size in composite lands around $13,500–$14,100. Our labor runs $28–$38 per square foot (end-of-2026-season rates); you pay the supplier directly for materials.
If you're Googling deck prices in Connecticut, you've probably found two kinds of answers: national aggregator sites quoting numbers from three states away, and contractors who won't talk price until they've been in your backyard. Here's a third option — real numbers from a Connecticut deck builder, so you can budget honestly before anyone sets foot on your property.
Our labor rates (end-of-2026 season)
We price labor per square foot, which keeps quotes transparent and comparable. These are end-of-2026-season rates — they may return to $32/$38/$42 for the 2027 season:
| Project type | Labor per sq. ft. |
|---|---|
| Ground-up build, up to 30" off grade | $28 |
| Ground-up build, over 30" off grade | $32 |
| Tear-down + full rebuild | $38 |
Staircases run +$500 each. The tear-down rate includes dumpster rental and the permitting cost.

Typical installed cost by material
Labor is only half the picture. Below are installed ranges built from our own math — our $28/sq ft end-of-2026-season labor rate plus current supplier material costs (decking, framing, fasteners, railing) for a standard ground-level build — so you can compare quotes apples to apples. Materials you pay directly to the supplier at cost, and prices are subject to change.
| Material | Typical installed $/sq ft |
|---|---|
| Pressure-treated wood | $36–$38 |
| Composite (Trex-class) | $45–$47 |
| PVC | Call for current pricing |
| Hardwoods (IPE & similar) | Call for current pricing |
These are typical Connecticut ranges, not quotes — your number depends on height, complexity, and current supplier pricing. Elevated builds run about $4/sq ft higher; tear-down and rebuilds about $10/sq ft higher.
Three real examples
12 × 16 pressure-treated deck, low to grade
192 sq. ft. × $28 = $5,376 in labor. A straightforward first deck — one staircase would add $500.
16 × 20 composite deck, elevated
320 sq. ft. × $32 = $10,240 in labor. Composite decking and railing materials run higher than wood, but you buy them at supplier cost.
14 × 20 tear-down and rebuild
280 sq. ft. × $38 = $10,640 in labor, dumpster and permit included. Common in Connecticut, where twenty-year-old decks are reaching end of life. Not sure yours is a teardown? Here's how to tell whether to repair or replace your deck.
What moves the price
- Height off grade. Anything over 30 inches needs deeper footings, taller posts, and more railing — hence the higher tier.
- Decking material. Pressure-treated wood is the most budget-friendly; composite and PVC cost more upfront but ask almost nothing of you afterward. IPE sits at the top.
- Railing choice. Standard railings are included in the per-foot rate. Glass panels (about $225 per section in labor) and cable rail ($25 per linear foot in labor) are upgrades.
- Stairs and levels. Each staircase is $500 in labor. Multi-level designs add framing complexity.
- Extras. Lighting ($150/hour to install), skirting ($100 per linear foot, labor), and design details like picture-frame borders add to the total.
- Site conditions. Slopes, ledge, or poor access can require helical piles (+$325 each) instead of standard concrete footings (+$250 each plus materials).
- Permits. Most Connecticut towns charge $150–$500 for a deck building permit — see our Connecticut deck permit guide for the full breakdown.
Questions to ask any Connecticut deck contractor
- Is your quote labor-only or all-in — and if all-in, what's the material markup?
- Are you a registered CT Home Improvement Contractor? (Ask for the HIC number.)
- Who handles the building permit, and is it in the price?
- How do you handle material warranties vs. your labor warranty?
- Can I see finished work in my area, not just photos?

Deck cost questions, answered
How much does a 12×16 deck cost in Connecticut?
At our end-of-2026-season $28 per-square-foot labor rate, a 192 sq. ft. ground-level deck runs $5,376 in labor. Materials are separate — you pay the supplier directly — and a pressure-treated deck this size typically lands between $6,900 and $7,300 installed.
Is it cheaper to build with wood or composite?
Pressure-treated wood is cheaper upfront — typically $36–$38 per square foot installed, versus $45–$47 for composite. But composite needs almost no maintenance, so over 15 years the total cost often evens out. Our labor rate is the same either way; the difference is all in the material.
Do I need a permit to build a deck in Connecticut?
In most Connecticut towns, yes — permits are handled at the town level, and fees typically run $150–$500. Our tear-down labor rate includes the permitting cost. Read our Connecticut deck permit guide for the full breakdown.
What does Da Deck Boss's labor rate include?
Framing, decking, and standard railing installation. Staircases ($500 each), glass or cable railing upgrades, lighting, skirting, and foundations are priced as separate line items. Materials are never marked up — you buy them from the supplier at cost.
How long does it take to build a deck?
Most residential builds take one to three weeks of construction. The full process — consultation, design, permits, and inspections — typically runs four to eight weeks. Here's what the timeline looks like
Should I repair my old deck or replace it?
If the ledger board, joists, and footings are sound, a repair or resurface can buy you years. If there's structural rot, replacement is the honest call — it doesn't get cheaper with time. Run through our repair-or-replace checklist before you decide.
The bottom line
A deck is one of the few home improvements you use every single day it's nice out. The cheapest bid in Connecticut is rarely the cheapest deck five years later — ask what's behind the number, check the HIC registration, and make sure material costs are transparent.
