Under $15,000 Deck Build
Comfortable mid-budget — fits a 16×20 mid-composite deck with composite or aluminum railing + properly sized framing. Most popular upgrade target for owners moving up from a 30+ year-old PT deck.
16×20 (320 sqft) mid composite (Trex Transcend, Fiberon Sanctuary) with composite or aluminum railing + 5-6 step stairs. Includes permit, demolition of existing deck if applicable, and standard 5-7 year contractor labor warranty.
Pick mid composite, not premium PVC (TimberTech AZEK). Use aluminum railing instead of cable ($30+/lf savings). Skip picture-frame border (save $400-700). Build during shoulder seasons (March-April, October-November) for 8-12% labor discount.
