How to Hire a Decks & Patios Contractor

Deck and patio contractors build new outdoor living spaces and replace aging structures using wood, composite decking, pavers, stamped concrete, and natural stone. Pressure-treated lumber is the most affordable decking material, while composite (Trex, TimberTech) offers low maintenance and longer warranties at a higher upfront cost. Decks attached to a house require a building permit and must meet code for ledger board attachment, joist spacing, railing height, and stair dimensions — improperly attached decks are a serious safety hazard. Patios are typically ground-level and may not require permits, but proper base preparation and drainage are critical for longevity.

Typical cost

$4,000 – $20,000per project

Pressure-treated wood deck: $15–$25/sq ft. Composite deck: $25–$50/sq ft. Paver patio: $12–$25/sq ft. A typical 300 sq ft deck runs $4,500–$15,000.

Hiring checklist

1Confirm the estimate specifies the decking material, framing lumber, and fastener system.
2Ask about their approach to ledger board attachment and flashing — the #1 point of deck failure.
3Verify they pull the required building permit for any attached or elevated deck.
4Ask about the warranty on both materials and workmanship.
