When a business’s plumbing system fails, the cost is lost hours, unhappy tenants, and customers turned away. Since 1995, Herndon McFarland Plumbing’s light commercial plumbing services in DFW have resolved complex day-to-day issues, keeping businesses open.

Our light commercial plumbing services cover the systems a business relies on every day, with a focus on service and repair rather than ground-up construction. Here is how we keep DFW businesses running.
When a system breaks down, fast repair gets you running again. Our commercial plumbing repair team responds quickly, diagnoses the failure, and restores your building with minimal disruption.
Restrooms are the first thing customers or tenants notice when something is wrong. We repair and maintain commercial toilets, urinals, faucets, and flush valves to keep your facilities open and usable.
Hot water is essential for a restaurant, salon, or medical office. We service and repair commercial water heaters, and when an aging unit costs you energy and downtime, we help you weigh replacement costs.
Slow or backed-up lines can quickly disrupt a business. We clear and repair commercial drains, and for heavy grease buildup or recurring blockages, we use hydro jetting to restore full flow.
Commercial buildings have testing obligations. At Herndon McFarland Plumbing, we handle backflow assembly service and repairs to keep your plumbing compliant.
A hidden leak in a commercial slab or wall can raise your water bill and threaten the structure. We locate and repair the pipe before it causes a closure.
The cheapest commercial plumbing problem is the one that never interrupts business. We schedule maintenance visits around your operation so small issues are caught before they shut you down.
A commercial building must comply with plumbing rules, beginning with legally required fixture counts. Commercial properties in Farmers Branch, Addison, and throughout DFW must comply with the International Building Code, which sets minimum counts of restroom fixtures based on occupancy load and use.
A restaurant seating 200 requires different restroom fixtures than an office of the same size. These minimums are non-negotiable in permitting. When a business changes use, adds seating, or builds out a tenant space, fixture count, accessibility clearances, and drainage must meet code for the current occupancy.
This separates commercial work from residential in DFW. Texas law does not exempt “small commercial” work, so any job in a commercial building requires a licensed commercial plumber, regardless of size. A dripping faucet in a home and a fixture change in a permitted commercial restroom have different obligations, even if the repair looks similar.
That is why Herndon McFarland Plumbing brings code awareness to every commercial call. We repair and service the systems your business runs on, keep fixture and accessibility work aligned with your building’s permitted occupancy, and flag anything that pulls you out of compliance.
Kristi Leonard has called us three times in five years and keeps coming back, the strongest endorsement a service company can receive. What kept her loyal was a consistent standard: no pressure, fair pricing, and crews she trusts on her property, whether she is there or not.
Kristi shared in her review:
“I have used this company 3x in 5 yrs, and I will never use anyone else as long as they are in business. The owner, Mr McFarland, and every worker on-site and in the office have always been professional and friendly. I’ve never been pressured or lied to about the work needed and pricing. After many other quotes, they’re fair and reasonable, and they work with you. The workers are trustworthy, and I can assure that my property is safe even if I am not there, and the work is impeccable. Thank you so much.”

Light commercial plumbing covers the service, repair, and maintenance of systems in businesses such as offices, restaurants, salons, retail spaces, and small medical facilities. It is distinct from ground-up construction and large industrial work. We focus on keeping existing commercial systems running rather than building new ones, where a responsive plumber is most important.
Commercial systems are larger, used more heavily, and subject to compliance obligations such as backflow testing. A failure costs differently: lost revenue, tenant complaints, and downtime rather than simple inconvenience. That is why we approach a commercial building as a business with uptime to protect, not just a set of pipes.
Yes. A breakdown rarely happens at a convenient time, and for many businesses, the safest repair window is outside operating hours. We respond to emergencies around the clock and work after hours when needed, so repairs cost your operation as little as possible.
It depends on the equipment’s age, condition, and failure frequency. A sound unit with a one-time fault is worth repairing, but equipment that keeps breaking down, especially a commercial water heater below current efficiency standards, costs you energy and downtime. We give you an honest read on what protects your budget.
Texas building codes set minimum restroom fixture counts based on a building’s occupancy and use, as well as accessibility requirements. A restaurant seating 200 needs different fixtures than an office of the same size. Texas law also has no “small commercial” exemption, so commercial work calls for a licensed commercial plumber regardless of job size.
Request commercial service online anytime. We respond quickly, offer same-day appointments when downtime cannot wait, and provide round-the-clock emergency service for businesses across the DFW metroplex.
From slab leaks under the foundation to sewer line repipes, every job is diagnosed, documented, and done right. A look at recent work across North Dallas.
Excellent customer service, very friendly staff from the person taking the call to the staff fixing the repairs. Very trustworthy company. Shaun explained the step-by-step process and provided very fair prices.
Their positive, upbeat, anxious-to-please attitude made the whole process the very best it could be! All of the employees were a pleasure to work with. I highly recommend Herndon McFarland.
Trent and Reggie were the most professional associates entering our home. They treated our home with respect as if it were theirs. We will use this company again because of them and our experience.
