Renovation Costs

How Much Does a Deck or Patio Cost?

Decks cost $25–$60+ per square foot; paver patios $15–$40 per square foot installed.

Deck vs patio

Decks suit uneven yards; patios work on level grade with proper base prep.

  • Pressure-treated wood deck: $25–$40/sq ft
  • Composite deck: $40–$60/sq ft
  • Concrete paver patio: $15–$30/sq ft

Permits and setbacks

Deck footings, railing height, and property line setbacks are enforced in most jurisdictions.

  • Call 811 before digging
  • Ledger attachment to house structure
  • Stair geometry and graspable rails

Pavers vs concrete

Pavers allow future changes; poured concrete is monolithic but can crack with soil movement.

  • Compacted base depth for freeze zones
  • Drainage away from foundation
  • Sealing and joint sand maintenance

Structure first if the ledger is suspect

Resurfacing boards on a rotten ledger is a cosmetic cover. Budget flashing to the house, hanger hardware, and footings that actually sit below frost before you price composite. Many “deck refreshes” should be 60% framing.

  • Pull a board and look at joist ends at the house
  • Call 811 before new footings
  • Railings are a code item once height triggers a guard — not an optional upgrade

Patio versus deck is a different dirt problem

A paver patio is excavation, base, and edge restraint. A deck is posts and air. Mixing those budgets is how a “$12k outdoor living” quote cannot decide whether you get a platform or a paved pad. Pick the system, then price it.

  • Slope patios away from basement windows
  • Composite on a new frame is not comparable to stain-only on old wood
  • Lighting and a gas line for a grill are separate trades
