Master Steam Heating Services

Traditional Steam System Knowledge Combined with Modern Safety


Steam Radiator & Main Vent Optimization

Classic steam radiators provide quiet, gentle heat, but require specialized care to balance steam delivery and eliminate banging pipes or cold radiators.


  • Air Vent Maintenance & Replacement: Upgrading faulty, clogged steam radiator vents and main line vents to allow trapped air to escape quickly and quietly.
  • Radiator Valve Restoration: Fixing leaking angle supply valves, repacking valve stems, and replacing worn union gaskets on historic cast-iron radiators.
  • Steam Pipe Pitch & Hammer Corrections: Adjusting radiator angles and correcting pipe pitch issues to ensure condensed water drains back to the boiler smoothly without causing loud pipe hammering.

Master Steam Boiler Safety

Because steam systems operate under heat and expansion pressures, maintaining reliable safety mechanisms is critical to protecting your home.


  • Pressuretrol Switch Tuning: Calibrating pressure controls so your steam boiler fires and cuts off at safe PSI levels (typically 0.5 to 2 PSI for residential systems).
  • Automatic Water Feeder Inspection: Servicing electronic water feeders to ensure your boiler maintains proper water levels without overfilling or dry-firing.
  • Skimming & Chemical Water Cleaning: Performing surface skimming on new or dirty steam boilers to remove oil and chemical residues that cause foaming and unstable water levels.
