What drives deck pricing in Massachusetts

The three structural factors that make Massachusetts more expensive than the national average for renovation projects in 2026.

Boston-area labor at $75–$110/hr

Greater Boston's trade labor market is one of the tightest in the country. Limited contractor density + high housing-prices-per-contractor pushes rates 30–50% above national average.

Stretch energy code (Mass. Building Code Appendix 115.AA)

Mass. is one of the few states that has adopted the Stretch Energy Code statewide. Window, insulation, and HVAC upgrades carry mandatory performance bumps that add $1,200–$5,000.

Pre-1940 housing stock

Roughly 35% of Massachusetts homes were built before 1940 — lead paint, asbestos, knob-and-tube wiring, and galvanized supply lines are common. Remediation routinely adds 8–15% to the bid.
