What we handle

Why is my boiler making hot water but not heating the house?

If you have hot water but no heat, the boiler itself is often fine and the problem is in the heating side: a thermostat, a zone valve, a circulator pump, or air trapped in the baseboard lines. Cornerstone Plumbing & Heating diagnoses heating zones and circulators for homes and rental properties around Milford.

Why is the heat not working in one room or zone?

When one zone stays cold, the usual causes are a failed zone valve or circulator, a bad thermostat or wiring for that zone, or air in the baseboard piping. Bleeding radiators can help with air, but valves and pumps need a professional. Call Cornerstone Plumbing & Heating at (508) 361-9450 and say which zone is cold.

Can Cornerstone replace my boiler and water heater with one system?

Yes. Cornerstone Plumbing & Heating installs combi boilers and has replaced a conventional boiler and separate hot water tank with a tankless system. That customer's review says Brandon handled the permits, met the inspector and walked them through the Mass Save rebates. Call (508) 361-9450 to talk through whether one system suits your home.

Does Cornerstone work on furnaces or heat pumps?

No. Cornerstone Plumbing & Heating works on oil and gas boilers, baseboard and radiator heat, and indirect water heaters. The only heat pumps it works on are heat pump water heaters, which it installs and services. For furnaces, forced air or heat pump heating and cooling, call an HVAC contractor. To ask about a boiler, call (508) 361-9450.

How much does it cost to replace a boiler?

It depends on the fuel, the size and type of boiler, whether the hot water setup changes too (an indirect tank or a combi boiler), and the piping and venting the job needs. Cornerstone Plumbing & Heating charges a flat rate by the task, explains the price and options before work starts, and offers financing.

Do I need a permit to replace a boiler in Massachusetts?

Usually, yes. In Massachusetts, only a licensed plumber can do plumbing work, and most work beyond a minor repair needs a permit from the local plumbing inspector before it starts. Cornerstone Plumbing pulls the permits for its jobs and meets the inspector to pass the rough and final inspections.

How often should a boiler be serviced?

Most boilers should be serviced once a year, ideally before the heating season starts, and oil boilers in particular need a yearly cleaning and tune-up. Booking in late summer or early fall avoids the rush when the first cold snap hits. Cornerstone Plumbing & Heating services boilers for homes and properties around Milford.

What are the heating rules for Massachusetts landlords?

Under the Massachusetts sanitary code, landlords who supply heat must keep habitable rooms at least 68°F during the day and 64°F at night from September 15 to May 31. Property managers dealing with a no-heat call can contact Cornerstone Plumbing & Heating at (508) 361-9450 with the unit address and system type.
