Using an integrated approach to design, fabrication and installation, JH Kelly’s team delivers systems to a job site faster due to our efficient shop environment.


JH Kelly maintains 100,000 square feet of fabrication area with 12 acres of secure adjacent lay-down area for storage. Our team pushes the envelope to:

  • Maximize pre-fabricated assemblies
  • Eliminate every field man-hour possible
  • Save clients’ money

Systems & materials fabricated in-house include:

  • Cast iron piping for bathroom
  • Waste and vent stacks
  • Water drops for sinks
  • Pump skids
  • Water closets
  • Shower assemblies
  • Mains and branches
  • Pre-fabrication of entire mechanical rooms

Field man power requirements are reduced by preassembling in the shop, as is the need for lay down space because components are prefabricated and modularly assembled for efficient installation.
