Deck Builder in Greater Boston

Deck construction in Massachusetts typically costs $18,000–$30,000 for a pressure-treated deck (400–600 sq ft with stairs and railing) and $28,000–$45,000 for a composite deck (Trex, Fiberon) of similar size. Multi-level decks, built-in seating, and pergola additions increase cost. Schlickmann includes permits and concrete footings in all pricing.

Yes — any deck over 200 square feet or attached to the house requires a building permit in Massachusetts. Permit fees vary by municipality. Schlickmann handles permit applications for all deck projects. Skipping permits creates problems at home sale — buyers' attorneys check permit history, and an unpermitted deck typically requires demolition or retroactive permitting.

Pressure-treated lumber is less expensive upfront ($18,000–$30,000 for a typical deck) but requires staining every 2–3 years and has a 15–20 year lifespan with proper maintenance. Composite decking (Trex, Fiberon) costs more upfront ($28,000–$45,000) but requires no staining, won't splinter, and carries a 25-year warranty. Most Greater Boston homeowners choosing composite consider it the better long-term value.

Massachusetts building code requires deck footings to extend below the frost line — a minimum of 48 inches deep in most of Greater Boston. This prevents the footing from heaving during winter freeze-thaw cycles. Schlickmann hand-digs or augers all footings to minimum 48-inch depth and uses tube-form concrete with code-compliant post bases. Footings poured at insufficient depth will heave, tilting the deck and eventually separating it from the ledger.
