Common questions

How much does a 16×24 Composite Deck cost in Maine?

About $19,873 fully built by a local crew in 2026, or roughly $7,017 for the materials kit alone. Most fair bids land between $18,283 and $21,860.

What drives the price up or down?

Do I need a permit?

Most counties require a building permit for structures over 200 sq ft. Call your county building department with your size and location before you order materials.
