Contact Boiler Guard Delaware
No forms, no queues. Call or email, and talk to a person about your boiler.
Call or email: that is how to reach us
There is no contact form on this site, on purpose. A form sends your message into a queue. A phone call gets you a person who can talk through what your boiler is doing, right now, and an email gets a written reply you can keep.
When you call, it helps to know three things: what kind of boiler you have (steam, hot-water, or combi, if you know), what it is doing (noise, leak, cold rooms, no heat at all), and when it started. If you do not know the boiler type, describe the radiators or baseboards instead: that tells us plenty.
We serve homes and businesses anywhere in Delaware. Our base is in Wilmington, and the map below shows where that sits in the state.

What to Tell Us When You Call
Three details make a call faster, and none of them requires technical knowledge. First, what the boiler is doing: no heat at all, a leak, a noise, cold rooms, or a pressure gauge that climbs or drops. Second, what kind of heat you have: radiators, baseboards, or radiant floors, and steam or hot water if you know it. Third, when it started, and whether it changed suddenly or crept in over weeks. With those three, the conversation can move straight to what to check and what the visit involves.
If you do not know the boiler type, describe the radiators or baseboards instead, since that tells us plenty. Cast iron radiators point one way, copper baseboards another, and a wall-hung unit in a closet points a third way. If the home is a rental, say so, since rental boilers often carry slow faults that tenants rarely report, like a weeping valve or a vent that hisses, and the check covers the whole system rather than only the reported fault.
For a planned job rather than a breakdown, the useful details are different: the age of the boiler if you know it, the pattern of recent repairs, and how the house has changed since the boiler went in, with insulation, windows, additions, or finished rooms. Those three shape the sizing conversation on the boiler replacement page and the boiler installation page, and they are worth gathering before you call, though a call without them still gets you a straight answer.
How a Service Visit Works
A visit follows the same order whether the job is urgent or planned, and knowing the order helps you judge the work as it happens. Testing comes before replacing parts, findings are explained in plain terms before any decision is asked for, and the system is left running through a full heat cycle, not merely switched on and declared fixed.
- Call or email with the symptom, the heat emitters, and the town and neighborhood.
- Talk through the simple checks: thermostat calling for heat, power to the unit, and the pressure gauge in its normal range.
- On site, expect the boiler, pump, controls, valves, and loops tested in turn.
- Discuss the findings and the options plainly, then leave the system through a full cycle from cold start to shutdown.
For anything urgent, call rather than email, since a call gets you a person who can talk through what the boiler is doing right now. For questions about a planned job, either works, and email gives you a written reply you can keep and refer back to when you compare options.
Coverage Across Delaware
Our base is in Wilmington, and the work runs statewide from there, for homes and businesses in all three counties. The locations pages cover the fifteen towns where boiler demand runs highest, from Wilmington in the north to Seaford in the south, each with its neighborhoods, ZIP codes, landmarks, and seasonal notes. If your town has no page, call anyway: statewide means the whole state, and the town pages describe the local conditions, not a boundary.
The full range of work is on the services page: repair, installation, replacement, maintenance, steam and hot-water systems, radiators, indirect tanks, combi units, baseboards, radiant floors, controls and zoning, flushing and water treatment, oil-to-gas conversion, and commercial work. If you are unsure which service fits, describe the symptom on the call and the right page will be pointed out, rather than asking you to choose from a menu of product names.
