New Plumbing Construction


Plumbing Design

  • Using the latest high-tech tools, our skilled designers create complex plumbing systems for commercial and industrial applications in retail, food service, live/work spaces, and more.
  • Our design-build and design-assist personnel create these systems from scratch to precisely meet your needs and satisfy the codes for each application.

Plumbing Construction

  • By building these systems in-house, and then installing them on-site, we capitalize on cost-savings through design efficiencies and prefabrication.
  • As a full-service contractor, our licensed plumbers apply their vast experience to your commercial plumbing and complex industrial solutions.

Maintenance and Repair


Vac-Truck Service

  • Inspecting and cleaning your catch basins is an essential stormwater source-control measure for both businesses and municipalities.
  • We specialize in industrial vacuum services, with all the equipment and personnel necessary to ensure timely service during a shutdown, outage, or scheduled maintenance.

Sewer Jetting

  • Avoiding sewer line backups should be a top priority for every business. These failures are disruptive, potentially dangerous, and expensive to repair.
  • JH Kelly can help keep your lines clear using high-pressure jetters, which remove solids, grease, dirt intrusion, and other debris from sewer lines.

Camera Inspection

Suspect a plumbing problem but don't know the source? Our camera equipment can travel the length of your line, methodically searching for problems. Once our licensed plumbers pinpoint the cause of your issues, we can work together toward a solution.

Our capabilities include:

  • Installation and repair of sanitary, storm and water utilities
  • Installation and cleaning of catch basins
