Gas Fireplace Repair & Service in Cambridge, MA

Gas fitting permits in Cambridge

Cambridge's Inspectional Services Department (617-349-6100) issues gas fitting permits. The city says a permit is required for all work done under the relevant provisions of the Massachusetts State Plumbing Code and Chapter 142 of the General Laws.

The state's plumbing and gas fitting board examines and licenses gas fitters at journeyman and master level, and licensed plumbers can do gas fitting as well. Its consumer page explains how to check a license and suggests asking to see the permit. Our repairs are done by a licensed Massachusetts gas fitter.

Cambridge's fossil-fuel-free ordinance and your fireplace

Cambridge adopted its Fossil Fuel Free Ordinance in August 2023 through a state program created for ten communities, and the regulations took effect on March 22, 2024. New buildings and major renovations must now be fossil fuel free: no oil, gas or other fossil fuels. Separately, the state's adoption list shows Cambridge on the Specialized energy code from July 1, 2023.

The city says the requirements do not apply to existing buildings that are not undergoing a major renovation. For one- and two-family homes and townhouses, a major renovation means renovating 50% of a building over 1,000 square feet, adding 1,000 square feet or doubling the building, or changing the use of 1,000 square feet. Inside a major renovation, no fossil fuel equipment may go into the work area covered by the building permit; the rest of the building is unaffected.

So repairing the gas fireplace in a home that isn't mid-renovation falls outside the ordinance, by the city's own description. Its FAQ gives a broken gas stove as an example: replacing it is not a major renovation, and any fuel is allowed. A new gas fireplace in a new building or a major renovation is the case the rule targets. Your contractor and Inspectional Services settle how a project is classified; this summary is not legal advice.

How Cambridge homes are built and protected

Almost half of Cambridge's housing is prewar. American Community Survey estimates for 2020-2024 put 47.0% of the city's 54,840 housing units in buildings from 1939 or earlier. Just 9.9% are detached houses, while 36.5% are in buildings of 20 or more units and 17.0% in buildings of three or four. Utility gas heats 63.6% of occupied homes, and the owner-occupied rate is 33.5%.

The Cambridge Historical Commission, founded in 1963, keeps records on all of the city's 13,000-plus buildings. Cambridge has two historic districts, Old Cambridge and Fort Washington, and four neighborhood conservation districts: Mid Cambridge, Half Crown-Marsh, Avon Hill and Harvard Square. The commission's FAQ lists interior alterations and work not visible from a public way among the jobs that get a Certificate of Non-Applicability instead of commission review.

With so many renters and multi-unit buildings, access is the practical question. Renters should get the owner's approval before booking, and condo owners can tell us about entry, parking and building rules when they request a time.

Eversource gas in Cambridge and what to do about a gas smell

The Department of Public Utilities lists Eversource (NSTAR Gas) as the gas company for Cambridge.

If you smell gas, get out first. Eversource's instructions for Cambridge are to move to a safe location and call 911, then report the leak to Eversource at 800-592-2000. Don't switch appliances on or off, open doors or windows, or attempt a repair. Our gas smell and carbon monoxide page also covers CO alarms. Book a fireplace visit only once the fire department or Eversource has cleared the home.

Three common fireplace faults

These guides walk through likely causes in the order a technician checks them, plus the owner-level checks worth doing first, like the wall switch and the remote batteries. If those don't solve it, book a repair visit; pilot and ignition faults get more depth on our pilot light and ignition repair page.

• Pilot is on, but the burner won't light
• Fireplace keeps shutting off a few minutes after it starts
• Remote or wall control not responding
