A business cannot wait days for a plumber. Our light commercial plumbing repair covers the systems that keep your doors open, with a response that respects how much downtime costs you. Here is what we handle across DFW.
A burst line or a failed water heater does not wait for a convenient time. We respond quickly and, when needed, work after hours to minimize disruption to your operation.
Out-of-order restrooms drive away customers and frustrate tenants. We repair commercial toilets, urinals, faucets, and flush valves, getting every fixture back in service so your space stays open and usable.
A leaking or failed supply line can shut down a whole floor. We locate the failure, repair or replace the affected section, and restore pressure with as little disruption as possible.
Backed-up drains in a business are an immediate problem. We clear and repair commercial drains and sewer lines. For heavy grease buildup or recurring blockages, we use hydro jetting to restore full flow.
No hot water can halt a restaurant, salon, or medical office. We diagnose and repair commercial water heaters, restoring hot water so your business keeps moving.
Commercial buildings carry compliance obligations that homes do not. We at Herndon McFarland Plumbing handle backflow assembly repairs and the fixes that keep your plumbing aligned with code requirements.
A hidden leak in a commercial slab or wall wastes water and damages the building. We locate and repair the pipe before it forces a closure, protecting both the structure and your budget.
A commercial building carries plumbing obligations that a house never does, and the most overlooked is backflow prevention. Any business connected to the public water supply with potential cross-connections, irrigation, boilers, kitchen equipment, or medical fixtures must have its backflow prevention assemblies tested. In Texas, that testing is governed by the Texas Commission on Environmental Quality.
The mechanism behind the rule is contamination. When pressure in the supply drops, water can reverse direction and pull contaminants from a building’s system back into the potable supply, which is exactly what a backflow assembly is designed to stop. When that assembly fails or falls out of compliance, the repair is not optional, and a failed test can put a business out of code until it is corrected.
This is where commercial repair differs sharply from residential work. A business owner is not only fixing a leak but also keeping the building compliant and operating. A missed obligation can mean fines or a shutdown on top of the original problem. The stakes are revenue and liability, not just a dripping fixture.
That is why at Herndon McFarland Plumbing, we approach commercial plumbing repair with both the breakdown and the building’s obligations in view. We repair the immediate failure, address backflow and code-related issues correctly, and keep your operation in compliance.
Mary Junge came to us after another company walked away, declaring the plumbing problem impossible and leaving the work unfinished. Taking over a job a competitor abandoned is the kind of challenge that separates a capable crew from the rest. The stakes were high with the problem still unresolved.

“We are well pleased with our experience with Herndon/McFarland. They took over our plumbing problem after another company came in and quit, saying it was an impossible task. They sent skilled teams that were easy to work with and did an outstanding job. We would recommend them to anyone needing a highly professional job.”
Sending skilled teams to finish what others could not is the same capability we bring to commercial breakdowns, where walking away is never an option for a business that needs to reopen. Read Mary’s full Google review.
Denton Wiginton faced a major plumbing problem requiring an extensive, multi-week project. A large job with many moving parts lives or dies on coordination. What stood out was a team that stayed attentive and easy to work with through completion.
He shared:
“The entire office staff, master plumbers and journeymen, including Lee McFarland, were attentive and easy to work with to completion of our extensive project. We highly recommend them to others with any residential plumbing issue!”
Coordinating a large team from office to field through to completion is exactly what a complex commercial repair demands, and it is how we keep your project moving without losing momentum. Read Denton’s full Google review.

Water where it should not be, multiple fixtures failing at once, no hot water, sewage odors, or a sudden drop in pressure across the building all require immediate response. In a business, these are not just inconveniences; they cost revenue and risk tenant or customer complaints. We respond fast, so a problem does not become a closure.
We assess the failure on-site, identify the cause, and provide a clear repair plan and upfront price before we begin. For commercial systems, we also flag anything affecting code compliance, such as a backflow assembly, so you are not blindsided by a second issue later. Then we repair with as little disruption to your operation as possible.
A breakdown rarely happens at a convenient time. For many businesses, the safest time to repair is outside operating hours. We respond to emergencies around the clock and work after hours when needed, so the repair happens at the time that costs your operation the least.
It depends on the equipment’s age, condition, and how often it fails. A one-time fault on sound equipment is worth repairing, but a unit that keeps breaking down costs you in repeated downtime. We give you an honest read on which path protects your operating budget over time.
Texas requires backflow prevention assemblies to be tested regularly under TCEQ rules, because a pressure drop can draw contaminants back into the potable supply. A failed assembly is both a health risk and a compliance issue that can leave your business out of code until it is repaired. We handle the repair and keep you compliant.
You can request commercial service online anytime, and we will respond quickly. We offer same-day appointments when downtime cannot wait and 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.
