Boiler replacement across Manhattan
Manhattan boiler replacement is mostly building work, planned months ahead with the managing agent and board: central steam plant replacements in pre-war buildings on the Upper West Side, Upper East Side and in Harlem and Washington Heights, with rigging, DOB filings, and the building kept in heat during the changeover. Townhouse replacements in Harlem, Chelsea and the Villages are smaller but harder on access: a boiler that comes in through a cellar hatch in pieces. In co-ops and condos we follow the alteration agreement and building hours and bring the certificates of insurance before the first day.
Manhattan is one bridge or tunnel away from our Greenpoint shop. We know the freight-elevator hours, the certificate-of-insurance paperwork and the alternate-side parking that make or break a Manhattan service call.
