What’s different about Massachusetts
Massachusetts combines harsh winters with strict permitting and some of the country's highest labor costs, making Boston-area exterior work expensive.
- Footings have to reach below the frost line, so deeper excavation adds cost.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
Expect quotes toward the higher end in Massachusetts’s larger metros — Boston, Worcester, and Springfield — where labor and permit costs run above the state average, and lower in rural areas.
How the cost is built
Deck cost depends on size, decking material (pressure-treated pine is cheapest; composite and PVC are mid-range; tropical hardwood is premium), and structural extras like railings, stairs, and elevated footings. Permits and ledger flashing add cost on attached decks.
Resale value
A wood deck recoups about 50–83% of its cost at resale — more than a composite deck — according to the annual Remodeling Cost vs. Value report.
