Leak Detection in Richardson, TX
Water bill jumped and nothing changed. Damp spot on drywall that will not dry. Meter dial spinning with every fixture off. We pinpoint hidden leaks in Richardson homes, condos, and townhomes using acoustic, thermal, and pressure gear — before anyone cuts into your finishes.
Find It First. Then Decide How to Open the Wall.
A leak inside a wall or under a slab wastes water quietly for weeks before it becomes visible. By the time you see a stain, the pipe has been running for a while and the framing behind the drywall has already absorbed most of it. The right first step is to pinpoint the leak so you open one square foot of drywall — not the whole wall guessing where the drip lives.
Richardson's mix of 60s and 70s ranches with wall-run copper, plus the newer Brookhaven condos with shared vertical stacks between units, means every leak call gets a different toolkit. Ranches usually get an acoustic pass and thermal imaging. Condos get acoustic plus a pressure test at the unit shut-off to isolate whether the leak is yours or a neighbor's stack.
We do not open drywall or concrete until we have a locate we can defend on a photo. That is what separates a $185 detection call from a $1,600 exploratory demo where somebody guesses and cuts.
Signs of a Hidden Leak in Your Richardson Home
These are the six signals we hear about most in Richardson. Any two together justify a detection call.
A hidden supply leak wastes 40-300 gallons a day. A $30-$120 jump on your Richardson bill with no new landscaping or fixtures is the number one call we get.
Shut every fixture in the home, wait 15 minutes, look at the meter's low-flow indicator. If it is moving, you have a supply-side leak somewhere.
A wall stain that gets bigger week over week is an active leak, not old damage. The source is usually a few feet up from the visible stain because water tracks along framing.
Mold behind drywall smells before it shows. If one room smells musty and the rest of the house does not, the leak is close.
A hot-side leak warms the surrounding material. Thermal imaging finds the source in about two minutes when the leak is on the hot line.
A supply leak large enough to feel drops household pressure or shortens shower duration. Combined with any of the above, it points at a specific line.
Acoustic, Thermal, Pressure — Whatever the Leak Needs
We do not guess. Every locate is documented on a photo you get in writing.
- 1Isolate the leak type
First we confirm supply vs drain, hot vs cold, by shutting valves in sequence and watching the meter. Half of leak calls turn out to be a drain or a fixture problem, not a supply line — no reason to acoustically hunt if the drain trap is the answer.
- 2Pressurize and listen
For pressurized supply leaks, we hold the line at 65 PSI and use ground microphones and wall probes to listen along the run. A pinhole makes a distinctive high-frequency hiss that geolocates within inches.
- 3Thermal image the walls and slab
A hot-side leak heats the surrounding wall or slab. Thermal camera makes the leak trail visible even through drywall and tile. On a cold-side leak, we run the hot-side longer to create the thermal contrast.
- 4Cross-check with tracer gas if needed
For tough locates — no water in the meter reading, quiet acoustic, ambiguous thermal — we introduce inert tracer gas into the isolated line and sniff along the run. Gas escapes exactly at the leak.
- 5Written locate report and photos
You get an X on a photo of the wall or floor with the depth, a description of the leak, and a written quote for the repair — whether that is our repair, another plumber's, or your own general contractor's.
Where Richardson Homes Tend to Leak
Vintage plus construction type predicts the failure location.
1970s-80s ranches on original Type M copper. Slab leaks and full repipes are the standard call.
Mid-century homes with cast iron drains and galvanized supply. Trenchless sewer replacements and repipes dominate.
1980s custom homes off Campbell. Aging copper slab leaks and water heater failures are the calls.
Older established homes near UT Dallas with mature oak canopies. Root intrusion at clay laterals is the daily work.
New mixed-use towers and townhomes. Angle stops, in-wall shut-offs, and tankless annual service dominate.
1960s-70s homes on original galvanized. Whole-house repipes and slab leaks are the mainstay.
