Heating & Plumbing in Manhattan
Manhattan buildings run on large central plants, tight mechanical rooms, and strict DOB oversight. We handle boiler replacements, gas piping, and code-driven inspections for co-op and condo boards, managing agents, commercial landlords, and institutions, scheduled around tenants and filed correctly the first time.
Emergency service 24/7
Most Manhattan apartment buildings are heated by a central steam or hot water plant in the cellar, and many of those plants are decades old. When a boiler fails in a building like that, dozens of households lose heat at once, so replacement has to be planned, permitted, and scheduled around residents. We size the new equipment to the building, file the work with the Department of Buildings, and coordinate shutdowns with the board or managing agent.
Manhattan buildings also carry a steady compliance load: a Local Law 152 gas piping inspection every four years, an annual DOB boiler inspection, and an annual DEP backflow test wherever a backflow preventer is installed. We handle the inspection, the filings, and the repairs that follow, so the paperwork and the work stay with one contractor.
