The job is planned so tenants and businesses keep water at the end of each day, and it is permitted and inspected so the building's records are in order.
Signs a building needs repiping
- Leaks on different floors within the same year
- Rusty water complaints from multiple units
- Low pressure on upper floors
- Galvanized risers visible in the basement with corrosion at the fittings
- Repair costs adding up faster than a repipe would
- An insurance carrier asking about the age of the supply piping
Commercial repiping services
Riser replacement
Hot and cold risers replaced in copper or PEX, one stack at a time, with new valves at each floor.
Branch and unit repiping
New lines from the riser to each unit's fixtures, with unit shutoffs so future repairs do not take down the building.
Basement main replacement
Replacing the corroded mains and headers that feed the building, plus the water heater and recirculation connections.
Copper or PEX
Copper where piping is exposed or where the building standard calls for it, PEX where it saves openings and time. We recommend based on the building.
Phased scheduling
Work staged by floor or stack with advance tenant notice, and water restored to occupied units every evening.
