Deck quotes in the Capital Region swing wildly, and most homeowners have no idea why one contractor says $12,000 and another says $28,000 for what looks like the same deck. The difference is almost always material, framing spec, and railing choice — not markup.
Ballpark cost per square foot
In Schenectady and the surrounding towns, a straightforward pressure-treated deck runs roughly $35-$50 per square foot installed. Cedar lands around $45-$65. Composite decking with composite or aluminum railing typically runs $60-$90 per square foot.
A common 16' x 20' (320 sq ft) deck therefore lands between about $11,000 for basic pressure-treated and $28,000 for a full composite build with premium railing and lighting.
What actually drives the price
Height above grade is the single biggest hidden cost. A deck three feet off the ground needs simple footings and a short set of stairs. A second-story deck off a kitchen needs taller posts, lateral bracing, longer stairs, and often a landing — easily adding 30-40%.
Railing is the second biggest. Pressure-treated wood railing is cheap. Cable, glass, and aluminum systems can add $60-$120 per linear foot.
Ground conditions matter too. Frost-depth footings in our climate need to go 42-48 inches down, and hitting ledge or fill can add excavation cost.
Permits and inspections in the Capital Region
Nearly every town here requires a building permit for a deck attached to the house. Permit fees generally run $75-$300, and you'll need a footing inspection before backfill and a final inspection before use.
A contractor who suggests skipping the permit is telling you something important about how they'll handle the rest of the job. Unpermitted decks also cause problems at resale.
Where homeowners overspend
Buying the most expensive composite when a mid-tier line performs nearly identically. Adding a huge footprint when a smaller, better-detailed deck gets used more. And paying for built-in features — benches, planters, pergolas — before confirming the base budget.
Where it's worth spending: framing hardware, joist tape, and proper flashing at the ledger. Those cost a few hundred dollars and add a decade of life.
Frequently asked questions
- Is composite decking worth it in Upstate NY?
- For most homeowners, yes. Composite costs 40-70% more up front but eliminates annual staining and holds up better to freeze-thaw and snow shoveling.
- How long does it take to build a deck?
- Most Capital Region decks take 1-2 weeks including footing and final inspections.
- Do I need a permit for a deck in Schenectady?
- Yes, for any attached deck. We pull the permit and handle both inspections as part of the job.
