Steam, hot-water and radiant heat in Hartford
We look after the boilers, cast-iron radiators and radiant floors of Hartford's older homes. Three generations of one family, one phone number, and a written note after every visit.
Heating season calendar
Put each of these in your phone. We do the first two; you can do most of the rest yourself, or call us.
We clean the burner, test the safety controls and look at the flue. On a steam boiler we also check the water in the gauge glass and flush the low-water cutoff.
On hot water, air collects at the top of a radiator and leaves it cold. We bleed each one, or show you how with the little key. On steam, we test every vent so no room heats late.
Pipes in an outside wall, a crawl space or an unheated porch freeze first. We insulate them, and shut and drain the outdoor hose faucets.
When the forecast drops, open the cabinet doors under sinks on outside walls and keep the thermostat steady, even if you are away. Know where your main water shutoff is.
A pipe that froze can split and only leak once it warms. After the first mild week, look in the basement and under the sinks for damp, and tell us about any spots.
A steam boiler is drained of sludge and refilled. On hot water, we check the pressure and the expansion tank before the long off season.
Steam heat
A steam boiler boils water, and the steam climbs the pipes to fill the radiators. When it works you hear almost nothing.
When it does not, you get banging pipes, one radiator that never gets hot, or a boiler that shuts itself off. Most of that traces back to a vent, a pitch or the water level, not to a boiler that has to go.
Air has to leave each radiator and water has to run back to the boiler. A stuck vent or a sagging pipe breaks both.
The gauge glass tells you more than anything else on the boiler. We teach you to read it.

What we work on

One-pipe and two-pipe: vents, valves, pipe pitch, gauge glass, low-water cutoffs and the boiler itself.

Cast-iron radiators and baseboard: bleeding, zoning, circulator pumps, expansion tanks and valves.

Loops and manifolds under floors, with mixing valves, pumps and a drawing of where every loop runs.

Boiler replacement sized to the house, indirect water heaters, and the supply and drain plumbing that goes with them.
Yearly service plan
Pick how much of the heating season you want us to watch. Each plan says what it includes and what it does not.
One boiler check before the first cold night.
A fall visit and a midwinter check, with a place at the front of the line.
The season plan, plus the hot-water side and a spring shutdown.
Not insurance: repairs, parts and labor beyond the visits listed are billed at our posted rates. Cancel before your renewal date by phone or email and the plan does not renew.
“Our one-pipe steam banged every morning. Lincoln found two vents that had stopped working and a radiator that sat tilted the wrong way. He fixed those, wrote it down and told us the boiler could stay.”
“I rent out the second floor, so a cold radiator is a phone call at eight at night. Sherene texts the arrival window, and the same crew came back in October to bleed every radiator in the house.”
“We put radiant loops under the kitchen floor of a 1920s house. Rui showed us the manifold and a drawing of every loop before the new floor went down.”

Where we go
Mostly houses built before the war: triple-deckers, brick two-families and wood-frame Victorians. If your town is not listed, call before you assume.
We do not work on the shoreline, in New London County or across the line in Massachusetts. If you are outside this list, ask anyway: we may know a firm near you.

Not as a first move. Most steam trouble comes from vents, pipe pitch or the water level, and those are repairs. We look first and write down what we found. If a boiler really is finished, we say why before we quote.
On steam, it is usually a vent that has stopped letting air out, or a valve left half shut. On hot water, it is usually air at the top of the radiator. Both are quick to check.
We clean the burner, test the safety controls and look at the flue. On steam we also check the gauge glass and the low-water cutoff. You get a written note of what we found and what we did.
Yes. We service the manifold, the mixing valve and the pump, and we install new loops in renovations. We do not pour or tile; we work with whoever does.
The visit fee and the hourly rate are told to you on the phone before we come. For anything bigger you get a written estimate that says what it includes and what it does not. Nothing starts until you say yes.
In heating season we answer no-heat calls every day until 8 p.m. After that the phone goes to a message that we hear at 6:30 the next morning. If you smell gas or a carbon monoxide alarm sounds, leave the house and call 911 and your gas utility first.
Not urgent?
A form suits a cold room, a noisy pipe or a job that can wait.
