Leak Detection and Repair in Houston, TX

Houston hides leaks well. High humidity masks the damp smell, gumbo clay swallows water from a broken yard line, and a slab leak can run for months under the foundation before anything shows on the surface. Molberg Plumbing locates leaks in Houston homes and businesses using infrared imaging, acoustic equipment, and line tracing, then repairs them properly once we know exactly where the failure is.
We’d rather find it now than after the flooring comes up. If your bill spiked, your water pressure dropped, or something just feels off, contact us and we’ll get you an answer.

Our Houston techs see the same handful of leaks over and over, though they rarely look the same from one house to the next. Here’s what tends to fail and what it looks like when it does.
Cracked supply tubes, loose P-trap connections, and corroded shutoff valves drip into the cabinet below. Given Houston’s humidity, the cabinet base and subfloor hold that moisture and mold takes hold quickly.
Water lines running beneath the slab corrode and split, and the resulting leak saturates soil that’s already unstable. Cracked tile, warm flooring, and a water meter that never stops moving are the giveaways. Our detection equipment finds the exact spot before any concrete gets touched.
Aging copper develops pinholes that weep into the framing for months. Look for bubbling paint, yellow or brown staining, and drywall that flexes when you press it. Second-story bathroom leaks show up on the ceiling below.
A deteriorated wax ring releases water onto the subfloor with each flush, and the damage collects under the flange where you’d never see it. A leaking flapper valve inside the tank wastes water constantly without any visible sign at all.
Outdoor faucets crack at the valve stem or below grade, sending water straight into the soil beside your foundation. That’s a problem in Houston, where saturated ground under a slab causes movement.
Corrosion at the tank base, a weeping T&P valve, or failed supply connectors mean the unit is on borrowed time. Water heaters in attic spaces are especially worth monitoring, since a failure there drains through the ceiling.
Failed pan liners, cracked grout, and worn valve seals let water pass into the subfloor and framing. In two-story homes the first evidence often appears as a ceiling stain downstairs.
Broken sprinkler heads, cracked lateral lines, and damaged service lines lose water underground. A patch of grass that stays greener than everything around it is frequently the first clue.
Washing machine hoses, dishwasher supply lines, and refrigerator ice maker connections fail without warning and flood a room in minutes. Replacing aging connectors is cheap insurance.

Monty digs a straight line from your call to a working pipe.
Reach us 24/7. A real person answers, and same-day slots are on the table for most projects.
We diagnose the real problem, walk you through the options, and put the price on paper first.
Repairs usually happen on the spot. Bigger jobs get scheduled around you, and every job is backed by our workmanship warranty.

Once we’ve located the leak, you get real choices. Sometimes a spot repair is the right call. Other times, rerouting a line above the slab or replacing a corroded section makes better financial sense than repairing pipe that will fail again next year. For failing sewer and drain lines, our Picote Solutions certification lets us rehabilitate many of them without excavating your yard or driveway. We price each option and let you decide.
A few habits cut your odds of another leak considerably. Keep grease and food waste out of kitchen drains, since buildup raises pressure inside the line. Replace flexible appliance connectors every several years rather than waiting for one to burst. Have your water pressure tested, and install a regulator if the reading comes back high.
Beyond that, annual plumbing maintenance catches the early warning signs: corroded connections, a water heater losing efficiency, valves that no longer seat properly. Our VIP Membership covers that inspection and gives Houston customers priority scheduling when something does go wrong.
Turn off every water-using fixture and appliance, then watch your meter. Most meters have a small triangular or dial indicator that spins when water moves. If it’s turning with everything shut off, you have a leak somewhere on your side of the meter.
No. Detection happens first, using acoustic listening gear, infrared imaging, and pressure isolation to narrow the location to a small area. Concrete only gets opened if you choose a direct repair, and even then it’s a targeted opening rather than an exploratory one.
The clay soil here expands and contracts dramatically with moisture, and foundations move with it. That movement stresses the copper lines running beneath the slab. Older neighborhoods with original plumbing see it most, but newer construction isn’t immune.
It can. A leak on the supply side reduces the pressure reaching your fixtures. Other causes include a failing pressure regulator, a partially closed valve, or mineral buildup in older galvanized pipe. We test to determine which one you’re dealing with.
Yes. We work with restaurants, offices, retail spaces, and multi-tenant properties across Houston, and we schedule detection work around your operating hours whenever the situation allows.
Most residential detection runs one to two hours depending on the size of the home and how accessible the plumbing is. You’ll know what we found before we leave, along with your repair options and pricing.
We run a camera through the line and show you the footage. Root intrusion, cracked cast iron, separated joints, and bellied sections each call for a different fix, and trenchless repair handles a good portion of them without heavy digging.
We provide written findings and photos of what we located and repaired, which gives your adjuster something concrete to work from. The claim itself is between you and your carrier, so call them early in the process.
Water heaters, repipes and sewer lines don’t wait for a good month. Get the price on paper first, then pay it off over time.
