Boiler Repair in Cohasset, MA
Cohasset's historic homes and coastal exposure create specific demands on aging boilers. We dispatch from Quincy and prioritize no-heat emergencies. Licensed MA plumber — we take emergency no-heat calls 24/7.
Why Cohasset boilers need expert service
Cohasset's historic town center and Jerusalem Road neighborhoods have some of the oldest homes on the South Shore — boilers in these houses are often 30 to 50 years old, operating well past designed service intervals.
Salt air from Cohasset Harbor and the coastal areas accelerates corrosion in boiler flue connections, draft hoods, and near-boiler piping in ways that inland systems don't experience.
Many Cohasset properties are seasonal or second homes that sit unused for months — boilers that restart in fall often reveal problems that developed undetected during the off-season.
Older colonial and Victorian homes in Cohasset have high-mass cast iron radiators that require careful boiler calibration for efficient, even heat distribution — not something a standard replacement handles without attention to the existing system.
How we handle Cohasset boiler problems
Boiler diagnostic and repair
We find the specific failing component and repair it — circulator, pressure relief, aquastat, gas valve, expansion tank.
Pressure relief and safety check
PRVs and low-water cutoffs are safety-critical and fail silently. We test and replace these on every service visit.
Boiler replacement
When repair no longer makes sense, we replace with correctly sized equipment, pull the MA permit, and commission the system.
The $99 service fee sends a licensed technician out to diagnose the problem. Approve the repair on the spot and the fee is not charged at all; decline it and the $99 covers the visit.

Cohasset boiler repair FAQs
Do you work in Cohasset often?
Yes. Heating and boiler work is 13% of the work we have completed in Cohasset. We dispatch to Cohasset from our Quincy office — usually about 25 minutes away.
How long do boilers last in Cohasset homes?
Cast iron boilers in Cohasset's older homes can last 30 to 40 years, but coastal salt air shortens the lifespan of exposed components. We assess condition rather than age and give you an honest recommendation.
My Cohasset home has a steam boiler. Do you service those?
Yes. Steam systems are found in Cohasset's older housing stock along the town center. We handle steam trap replacement, venting, near-boiler piping, and pressure controls.

Yes. We dispatch to Cohasset from our Quincy office — usually about 25 minutes away. No-heat calls get priority in winter. Call (617) 479-9911.
Should I repair or replace my Cohasset boiler?
If repair cost is under 40 percent of replacement and the unit is under 20 years old, repair usually makes sense. We give you both numbers honestly and let you decide.
