Tell us what's going on and we'll text you back fast. No obligation.
A Plano house built during the city’s long residential build out is now old enough that the supply piping, the drain line under the slab, and the water heater all reach the end of their service lives within a few years of each other. That is the pattern here. Not one failure, a sequence of them. Herndon McFarland Plumbing has worked on Plano homes since 1995, and our team brings over 150 years of combined experience to the diagnosis.

Plano sends us the full range, from a running toilet to a collapsed drain line under a forty year old slab. We kept the list wide for that reason.
Sewer camera inspection, pipe repair, and plumbing maintenance belong to the same trade. Our own licensed technicians do all of it, which is what lets us stand behind the labor.
You can learn something about a city’s plumbing from what it offers homeowners money for. The City of Plano runs the Great Update Rebate to help with the cost of caring for older homes, and a house has to be 30 years or older to qualify. No city builds a program like that for a handful of properties.
That 30 year line matters to a plumber because of what it implies about materials. A Plano home past it is on at least its second water heater. Its supply piping has spent three decades carrying mineral rich North Texas water, and scale narrows a pipe from the inside until pressure falls off across the whole house. What sits under the slab depends on which decade the street went in. Earlier construction here used cast iron drain lines, which corrode along the bottom of the pipe where waste sits. Later construction used PVC, which does not corrode but does move when the clay beneath it swells and shrinks. We put a camera in the line instead of guessing from the address.
One detail worth knowing before you plan around that rebate: the interior work it covers is limited to the mobility improvements the city lists, so a repipe or a sewer replacement is not what the money is for. Budget the plumbing on its own, and have the lines inspected before the rest of a remodel is committed.
Pressure That Fell Off Gradually
A whole house losing pressure over several years points at the supply piping rather than at one fixture.
Two or More Drains Slowing Together
That puts the restriction past the fixtures and into the main line.
A Water Bill That Climbed With No Change in Use
Beneath a slab, a leak can run for months without reaching the surface.
Most Plano homeowners reach us after someone has already looked at the problem once. This is what they get the second time.
We diagnose first and quote second, because cost depends on what is actually wrong, not on what the symptom looks like.
Describe what the house is doing and how long it has been doing it, and we will tell you what needs looking at first. Licensed, insured, bonded, and working in this city since 1995.

It depends on the scope. Small repairs such as a faucet cartridge or a toilet flapper generally do not. Replacing a water heater, repiping, replacing a sewer line, altering gas piping, or changing the drain system is regulated work that generally requires a permit and an inspection through the City of Plano. Requirements shift with the details of the job, so we confirm what applies before starting and handle the permit and inspection when they are part of the work. Undocumented plumbing tends to surface again at resale.
Not in the way most homeowners hope. The program is aimed at exterior improvements, and the interior work it covers is limited to the mobility improvements the city publishes, so a repipe or a sewer line replacement generally falls outside it. Eligibility also depends on the house being 30 years or older, being owner occupied, and meeting the city’s property value and minimum spend rules, and the funding available each year is limited. Confirm the current terms with Plano Neighborhood Services before you build a plan around it.
The build date narrows it down and a camera settles it. Earlier construction in this city typically ran cast iron below the slab, while later construction used PVC. Rather than guess, we run a camera through a cleanout and look at the pipe wall directly. Cast iron that has been in service for decades scales inward, then channels along the bottom where waste has sat. Seeing the actual condition is what tells you whether you are looking at a spot repair or a replacement, and how far it runs.
Two things stack up. North Texas clay swells with rain and shrinks in drought, and that seasonal movement works on pipe joints below the foundation year after year. On top of that, the lines themselves are decades into their service life across much of the city. A rising bill with no change in use, the sound of water running with every fixture off, or a damp area on a floor are the usual first signs. We locate the leak before deciding whether to repair it, reroute it, or tunnel to it.
A failed thermostat, element, gas valve, or anode rod is usually a repair. A tank leaking from the body, heavily corroded, or well past its expected service life is usually a replacement, and in a Plano home past the 30 year mark it is often the second or third unit to sit in that closet. Sizing matters as much as the decision itself, since a heater that never kept up with the household will not start keeping up now. We inspect the unit and explain which of the two you are facing.
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.
