My Conroe water bill doubled this month. Where do I start?

What our slab leak detection covers in Conroe
We do one thing: find leaks under concrete slabs. Every visit is done by an independent, licensed Texas plumber who specializes in leak detection, so you pay to find the leak, not to break concrete searching for it.
Water Line Leaks
Find leaks in the pressurized supply lines buried in or under your slab.
Hot-Water Line Leaks
Thermal imaging traces warm spots and leaking hot-water runs.
Drain Line Leaks
Hydrostatic and isolation tests find drain leaks that never show on your meter.
Pressure Testing
Confirm a leak exists and measure how fast the line loses pressure.
Line Isolation & Tracing
Separate hot, cold and branch lines and map where they really run.
Acoustic Pinpointing
Ground microphones hear escaping water through the concrete.
Tracer Gas Detection
For very quiet leaks and plastic pipe, gas rises at the leak point.
Written Leak Report
Exact location, readings and photos for your insurer or water utility.
Why slab leaks happen in Conroe
North of Houston, clay and sandy soils hold water after heavy rain, and many homes are billed by a MUD. Flood history makes it important to tell storm water from a plumbing leak.
Conroe has older in-town homes and many newer master-planned neighborhoods, some billed by a MUD.
Serving homes across Conroe, including neighborhoods near Lake Conroe, Historic Downtown Conroe, Interstate 45.
Why should Conroe homeowners check with their MUD after a leak?
Many homes here are billed by a municipal utility district rather than a city. Most MUDs have their own leak-credit rules and deadlines, so call soon after the repair with your plumber's invoice in hand.
How we find a slab leak without tearing up your floor
The same nine steps on every job, so you know what’s happening and why. Read the full process →
Listen and look first
The plumber hears what you've noticed and walks the home to look for clues.
Rule out the easy causes
Toilets, faucets, irrigation, the water heater and the AC drain are checked so you don't pay to search for the wrong leak.
Confirm the leak with the meter and a pressure test
A meter test and a pressure test prove water is escaping from the plumbing.
Isolate the leaking line
Hot, cold and branch lines are separated so the search focuses on the one that's leaking.
Test the drains, if needed
Drain leaks don't show on the meter, so they get their own hydrostatic test and camera check.
Trace the pipe's route
An electronic locator maps where the leaking line actually runs under the floor.
Pinpoint the exact spot
Acoustic listening, thermal imaging and tracer gas find where the water is escaping, and two methods must agree.
Scan the slab and mark the leak
The slab is checked for steel tendons and rebar, and the leak is marked on the floor.
Get your written report
You receive the leak's location, the line, the readings and photos in writing.

Slab leak specialist vs. general plumbing contractor
Many general plumbers do excellent work. The difference is focus and equipment when the leak is hidden under concrete.
| What matters | Slab leak detection specialist (our network) | Typical general plumbing contractor |
|---|---|---|
| Main focus | Only finding hidden leaks under slabs | Installs, repairs and remodels across all plumbing |
| Detection tools | Acoustic ground mics, thermal imaging, tracer gas, line tracing | Varies; often a pressure test and visual inspection |
| Locating the leak | Pinpointed before any concrete is opened | May open the floor in more than one place to search |
| Drain leaks under slab | Hydrostatic, isolation test and camera find the broken section | May recommend replacing the whole drain system |
| After the leak is found | Exact spot marked and documented; you choose who fixes it | Often moves straight into its own repair or repipe |
| Paperwork | Written report with photos for insurance and water credits | Usually an invoice only |
| Typical cost to locate | $150–$600 in most Conroe homes | Varies; exploratory openings add cost |
Tip: whoever you call, ask which detection methods they use and whether they’ll pinpoint the leak before opening the slab.

Will I still pay for detection if no leak is found?
Usually yes, because detection is a diagnostic service. If no slab leak is found, you still learn where the water isn't going, which rules out costly guesses. Ask about the fee before the visit.
Insurance and slab leaks in Texas
Coverage depends on your policy and the cause. The Texas Department of Insurance has long said the standard HO-B policy covers damage to the dwelling, including the foundation, from an accidental discharge of water from a plumbing system. Many policies still exclude wear and tear, the pipe itself, and mold.
What helps your claim: shut off the water, protect your belongings, and get the leak documented by a licensed plumber before the adjuster visits.
Ask for a leak credit
Many Texas cities and MUDs credit part of the water lost to a hidden leak once it’s repaired. Most want a paid plumber’s invoice and a request within a set number of days, and allow one credit a year.
Keep your invoice, and call your utility soon after the repair to ask about its rules and deadline.

Call (000) 000-0000My Conroe home is in a MUD. Can I get a credit for a slab leak?

How do I get a leak credit from my MUD in Conroe?
Many MUDs offer leak adjustments, but each has its own rules. Call your MUD's billing office, ask about its leak policy and deadline, and keep the plumber's invoice showing the leak was repaired.
After a flood in Conroe, how do I tell storm water from a slab leak?
Once the ground dries, do a meter test with every fixture off. If the meter moves, your own plumbing is leaking. Floors that stay damp or warm long after a storm also point to a slab leak.
Is a slab leak in my Conroe home an emergency?
Water coming up through the floor, a sewer smell or a fast-spinning meter needs help the same day. A slower leak should still be checked within days, because water under the slab can wash out soil and grow mold.
Why is there a warm spot on my floor?
A warm spot on tile, wood or carpet is a classic sign of a leaking hot-water line under the slab. Thermal imaging can confirm it and trace the line. Turn off the water heater's cold inlet and call a plumber.
How much does slab leak detection cost in Conroe?
Detection usually runs $150–$600, depending on the size of the home, the number of lines and how hard the leak is to hear. You get the price before the visit and a written report of what was found.
