Commercial Plumbing

When a plumbing problem hits a business, every hour of downtime costs money. A restaurant with a backed-up kitchen drain has to stop serving; an office with no working restrooms has to send people home. Houston Flow Plumbing has kept Houston businesses running since 2010, and our 22-truck fleet with true 24/7 live dispatch means a real plumber is on the way fast, with no overtime surcharge no matter the hour. We work across Houston, Sugar Land, Katy, Pearland, and the surrounding metro on properties of every size.

Commercial systems are bigger, busier, and held to stricter code than residential, and our Texas Master Plumbers are built for that work. We serve:

  • Restaurants and food service including grease trap service, high-volume drain cleaning, and water heater systems
  • Offices and retail for restroom maintenance, fixture repairs, and ADA-compliant upgrades
  • Multifamily and apartments for unit turnovers, repiping, and slab leak work
  • Medical, dental, and professional buildings requiring backflow protection and reliable hot water
  • Warehouses and light industrial facilities with large-diameter sewer and supply lines

Our commercial crews handle the heavy-duty versions of every service we offer. That includes hydro-jetting for grease-clogged lines under our drain cleaning service, video diagnostics through sewer camera inspection, and full-line replacement via sewer line services when a property's underground piping fails. We also keep businesses code-compliant with annual backflow prevention testing, which the City of Houston requires for most commercial water connections.

We understand that commercial work has to be scheduled around your operations. For non-emergencies, we arrange service before opening, after closing, or overnight so your customers and staff are never disrupted. For true emergencies, we respond immediately, isolate the problem, and get you back online with flat-rate pricing presented before work begins so there are no surprise invoices. Every permitted job is documented and passes city inspection, protecting you on compliance and resale.

For property managers and business owners who would rather prevent problems than react to them, we offer scheduled preventive maintenance plans covering drain jetting, water heater servicing, backflow testing, and full-system inspections. Pricing scales with the size and complexity of your facility, and we provide written estimates for budgeting. GreenSky financing is available for larger commercial projects and capital repairs. Houston Flow Plumbing carries full insurance and an A+ BBB rating, so you are protected on every job.

Answers

Frequently asked

Do you offer after-hours commercial plumbing in Houston?

Yes. We run true 24/7 live dispatch with 22 trucks across the Houston metro and never charge an overtime surcharge. For non-emergency work, we schedule around your hours, before opening or after closing, so your business is not disrupted. For emergencies, we respond immediately any time of day or night.

Can you service grease traps for my restaurant?

Yes. We service and maintain grease traps and handle the high-volume, grease-heavy drain lines that restaurants deal with, including hydro-jetting to clear buildup. Keeping traps and lines clear prevents the backups that force a kitchen to shut down during service.

Does my Houston business need annual backflow testing?

Almost certainly. The City of Houston requires annual certified backflow testing for most commercial water connections. Our certified testers handle the test, any needed repairs, and file the report with the city so you stay compliant and avoid violation notices.

Do you offer preventive maintenance contracts?

Yes. We build scheduled maintenance plans for property managers and business owners covering drain jetting, water heater servicing, backflow testing, and full-system inspections. Catching small issues early is far cheaper than an emergency shutdown, and we provide written estimates so you can budget.

Are you licensed and insured for commercial work?

Yes. We hold Texas Master Plumber License #M-41872, carry full insurance, and maintain an A+ BBB rating. Every permitted commercial job is documented and passes city inspection, which protects you on code compliance, liability, and future resale of the property.
