Boiler & Radiator Repair in Petworth, Washington, DC

Last updated November 5, 2026

Cold radiators, banging pipes and a pressure gauge in the wrong place are the boiler calls we take in Petworth through the winter. Calls from Sherman Circle to Petworth Metro are answered 24/7.

Petworth streets and layouts

Petworth's grid of numbered and lettered streets fans out from Grant Circle and Sherman Circle, and most rowhouses share party walls, a shallow front porch and a narrow rear yard backing onto an alley. Equipment is usually in the basement at the back of the house.

Signs you need boiler & radiator repair

• Combi boiler with no hot water
• Water leaking at the boiler base
• Radiators cold on one floor
• Boiler pressure too high or too low

How we handle it

We explain what an old boiler still has left in it and what a replacement would involve, without pressure either way.

Petworth boiler owners can glance at the pressure gauge before we arrive. A reading under 12 psi on a cold boiler, or a relief valve dripping into a bucket, tells us a lot over the phone.

Systems we find in Petworth

A lot of Petworth rowhouses still have their original hot water boiler and radiators, while renovated homes usually switched to a basement gas furnace or a heat pump with a closet air handler. Rooftop condensers are common because rear yards are small.

Petworth has more original cast iron radiator systems than most neighborhoods, and many of those boilers are on their second or third circulator pump. When a circulator fails, the boiler fires but the water never moves, and the radiators stay cold while the boiler itself gets hot.

Pricing

If the boiler is near the end of its life, you get the repair number and the replacement number side by side.
