What’s different about Maryland
Maryland's humid mid-Atlantic climate and higher labor and permit costs near the D.C. corridor push exterior projects above the national average.
- Rot- and mold-resistant or composite materials are favored in humid climates.
- 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 Maryland’s larger metros — Baltimore, Columbia, and Silver Spring — 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.
