Why Boston costs more than the rest of Massachusetts
Boston carries roughly a 20% premium over the Massachusetts statewide figure. Three things drive that gap. Metro wages run above the state average, and labor is about 40% of this bill. Permitting and inspection are slower and more expensive inside city limits. And site access is tighter, which means smaller equipment, more hand work, and sometimes street permits for deliveries.
Statewide, Massachusetts averages $4,824 to $10,184 installed, against $5,789 to $12,221 inside Boston. Suburbs on the metro fringe usually fall between the two.

Permits in Boston
A residential permit for this work typically runs around $700 in Massachusetts, and metro jurisdictions like Boston usually sit at the upper end of that range with longer review times. Permit cost is rarely included in a contractor quote, so add it separately. Confirm scope with the Boston building department before work begins.
Hiring in Boston
Get three written, itemised quotes from licensed and insured contractors, and make sure each specifies the same dimensions and the same grade of material. In a metro market, the cheapest bid often reflects a thinner specification or a crew travelling in from outside the area rather than a genuine saving. Ask for local references and check that the licence is current in Massachusetts.
