Boiler replacement across Brooklyn
Brooklyn replacements split into two jobs. In brownstones and rowhouses, we replace steam boilers with steam boilers, sized to the connected radiation rather than guessed, with new near-boiler piping done to the manufacturer's drawing, because bad header piping is why so many Brooklyn steam boilers surge and bang from day one. In the newer houses of Bensonhurst, Dyker Heights, Mill Basin and Canarsie, and in gut renovations in Williamsburg, Bushwick and Crown Heights, the replacement is usually a condensing hot water or combi boiler vented out a side wall, which frees the chimney and the closet the old boiler took.
Our shop is at 854 Humboldt Street in Greenpoint, so Brooklyn is home turf: most of the borough is under 30 minutes from the truck.
