Hirst Plumbing & Mechanical provides a full range of commercial plumbing services throughout East Moline and the Quad Cities, including new construction plumbing, rough-in plumbing, water line installation, sewer line installation, commercial plumbing repair, preventative maintenance, fixture installation, and plumbing system upgrades.

Yes. We partner with general contractors, developers, project managers, and property owners on commercial construction projects. Our team coordinates closely with other trades to help keep projects on schedule while meeting all plumbing specifications, inspections, and code requirements.

We work with a variety of commercial and industrial facilities, including:

  • Office buildings
  • Retail centers
  • Restaurants
  • Warehouses
  • Manufacturing facilities
  • Medical offices
  • Schools
  • Apartment communities
  • Property management companies

Absolutely. We provide commercial plumbing rough-ins for new construction projects, tenant improvements, remodels, and facility expansions. Our rough-in services include underground plumbing, drain, waste and vent systems, water supply lines, restroom plumbing, and inspection preparation.

Common warning signs include recurring drain clogs, sewer odors, low water pressure, unusually high water bills, water stains, leaking pipes, slow drains, or frequent plumbing backups. Addressing these issues early can help prevent costly repairs and business interruptions.

Most commercial properties benefit from annual plumbing inspections, while higher-use facilities such as restaurants, manufacturing facilities, and multi-tenant properties may require more frequent maintenance. Regular inspections help identify issues before they lead to unexpected downtime or expensive repairs.

Yes. Routine maintenance helps identify leaks, worn components, drain issues, and other developing problems before they become major failures. Preventative maintenance can extend the life of plumbing systems, reduce repair costs, and help businesses avoid unexpected disruptions.

If something sounds unusual, smells unusual, drains slowly, leaks unexpectedly, or simply doesn’t seem right, it’s usually worth getting it checked out. Plumbing problems rarely improve on their own, and catching issues early is almost always less expensive than dealing with a major repair later.

If your building starts making plumbing noises you’ve never heard before, that’s your cue to call us, rather than increasing the volume of the tv.
