$15 to $80 per square foot installed. Pressure-treated pine runs $15–$35, composite $30–$60 and tropical hardwood $40–$80.

How long does deck construction take?

One to two weeks for a standard deck, plus permit review time before the crew starts.

Does a deck add value to my home?

A wood deck addition typically returns 50% to 65% of its cost at resale, and it is one of the most-requested outdoor features in listings.

What is the cheapest way to build a deck?

Keep it rectangular, ground level and under 200 square feet, frame and surface it in pressure-treated pine, and skip railing, stairs and picture framing.
