Listens for the hiss of pressurized water escaping a pipe. We walk the slab and walls with it and mark the loudest point, which is usually within a few inches of the leak.

What our leak detection service includes
Every leak detection call includes the full diagnostic process, not just a quick listen.
Work order
Leak Detection- Full system pressure test: We isolate the house from the city main, attach a gauge, and watch the needle to confirm whether the leak is on the supply side. Then we split hot from cold to narrow it down.
- Acoustic listening survey: We walk the slab, walls and yard with an acoustic microphone, listening for the hiss of pressurized water. This is how we find slab leaks and underground line leaks without digging.
- Thermal imaging scan: A thermal camera shows hot water leaks as warm streaks and cold leaks as cool spots. We scan the suspect area and mark the location on the floor or wall with tape.
- Sewer camera inspection: For drain and sewer leaks we run a RIDGID camera down the line to look for root intrusion, cracked joints or bellies. You see the footage on the monitor with us.
- Tracer gas confirmation: For leaks under thick concrete or in hard-to-reach lines, we inject tracer gas into the isolated pipe and read it at the surface. Gas finds leaks that acoustics miss.
- Written findings with photos: You get a written summary of what we found, where it is, moisture readings, and photos of the marked location. It is yours to keep, whether you hire us for the repair or not.

Leak Detection New Braunfels TX done without guesswork
A leak found early is a small repair. A leak found late is a foundation, a floor and a mold bill. We find it with instruments, mark it, and fix it before it spreads.
Leak detection New Braunfels TX is the process of locating water escaping from a pressurized supply line, drain line or fixture using instruments rather than guesswork. We pressurize the system, isolate sections, then listen with acoustic microphones and scan with thermal cameras until the leak announces itself. Copper pipe under a 1980s slab sounds different than PEX tubing behind drywall, and we read both. Once we know exactly where the water is leaving, we can open one small area instead of a whole room.
New Braunfels sits on a mix of clay, limestone and river rock, and that ground moves with every wet and dry cycle. Supply lines under slabs shift, solder joints fatigue, and older galvanized or copper pipe in Gruene and Downtown homes develops pinholes you cannot see. when nothing is on, it is time to call. We handle hidden water leak detection New Braunfels wide, from River Chase to Solms.

What to expect on leak detection day
Every leak call follows the same five steps.
Tools and methods we use to find leaks
Each method answers a different question. Together they leave very little to guess.
Shows hot water leaks as warm streaks and cold leaks as cool spots on the floor or wall. Confirms what the acoustic mic hears.
Runs down drain and sewer lines to find cracked joints, root intrusion and bellies. You watch the footage on the monitor with us.
Injects a safe gas into an isolated line and reads it at the surface. Finds leaks under thick concrete that acoustics cannot reach.
Confirms whether the system holds pressure and how much water is being lost. This is the first test on every leak call.
When to call for leak detection
You hear water running at 2 a.m. when every fixture in the house is off.
We come out the same day, pressure-test the system, and use acoustic listening to trace the sound to its source.

How leak detection runs in New Braunfels
New Braunfels sits on a mix of clay, limestone and river rock, and that ground moves with every wet and dry cycle. Slabs shift, supply lines fatigue, and older copper pipe develops pinholes you cannot see.
Downtown New Braunfels
Many homes here date to the 1950s and 1960s with original copper supply lines under slab. Pinhole leaks are common, and we see them most often in the hot water line.
Gruene
Older homes with pier-and-beam foundations and galvanized pipe. Leaks here often show up as rust-colored water or a soft spot in the wood floor.
Veramendi
Newer construction with PEX tubing. When leaks happen, they are usually at crimp fittings or where the line passes through a slab penetration.

PhotoSlab leak under a Gruene hallway
Before: The floor was warm to the touch, and the meter spun with everything off. They had been putting off the call for three weeks.
After: We pressure-tested the system, confirmed a hot water slab leak, and marked it with thermal imaging. One 2-foot access cut, a copper line repair, and a 30-minute pressure test later, the meter held still. The bill returned to normal the next cycle.
Underground line leak in Vintage Oaks
Before: A Vintage Oaks homeowner had a soggy patch in the yard that never dried out, even in summer. Two other companies had dug in the wrong spot with no result.
After: We isolated the house from the main, confirmed the loss, and used tracer gas to find the leak in the main supply line 18 inches below the surface. One small excavation, a PVC repair, and a pressure test. The yard patch dried out within a week.
Hidden wall leak in a Downtown bungalow
Before: A 1950s bungalow in Downtown New Braunfels had a musty smell in the hallway and a faint stain on the baseboard. The homeowner thought it was humidity. A moisture meter read 28 percent at the base of the wall, well above the 15 percent dry standard.
After: We used acoustic listening and a borescope to find a pinhole leak in a copper supply line inside the wall. We opened a 12-inch section, repaired the pipe, and pressure-tested. The wall dried to 12 percent over the next week with a fan.
Leak problems we solve for New Braunfels homeowners
Most leak calls fall into a handful of patterns.
Water bill jumped with no change in habits
Left alone, it also saturates the soil under your foundation. We pressure-test the system, isolate hot from cold, and use acoustic listening to find the leak.
Warm spot on the floor over a hot water line
A hot water slab leak heats the concrete and can crack tile, warp flooring and drive up your gas or electric bill.
Soggy patch in the yard or a sewage smell
An underground line leak or sewer break can undermine a driveway, kill grass in a stripe, and let sewage into the soil.
Musty smell or stain on a wall or ceiling
A slow drain or supply leak behind a wall feeds mold in 24 to 48 hours in our humidity.
Why find the leak before you dig
Water does not stay where it starts.
Stop the water bill bleed
We isolate the line, confirm the loss with a flow meter, and shut the leak down before the next billing cycle.
Protect the foundation
Comal County clay expands when saturated and shrinks when it dries.
Open one small area
Blind digging destroys tile, hardwood and concrete.
Catch mold before it spreads
A leak behind a shower wall or under a kitchen sink feeds mold in 24 to 48 hours in our humidity.

What New Braunfels homeowners say
Our water bill doubled in one month and we could not figure out why. Comal Crest came out, pressure-tested the system, and found a slab leak under the hallway with the acoustic mic in about 40 minutes. They marked it, opened one small section, and repaired the copper line the same day. Bill went back to normal the next cycle.
We had a warm spot on the tile floor for weeks and kept putting it off. They confirmed it was a hot water slab leak, showed us the thermal image, and gave us a flat price before cutting. The repair took a few hours and they pressure-tested it with us watching. No more warm floor.
We manage several commercial buildings and had a tenant complaining about a soggy patch in the parking lot. Comal Crest ran a camera and tracer gas, found a cracked irrigation line, and repaired it without tearing up the whole lot. They documented everything with photos for our records.

Describe what you are seeing and we will point you to the right next step.
(737) 707-1110A single-fixture check is on the low end. A full slab scan with tracer gas is on the high end. The repair is priced separately, and you approve it before we open anything.
Comal Crest Plumbing does, and we have since 2010. We handle both the detection and the repair, so you are not bouncing between two companies. Call (737) 707-1110 to schedule.
Three signs point to a slab leak in Texas: the water meter spins with every fixture off, you hear running water when the house is quiet, and a warm spot shows up on the floor over a hot water line. Cracks in tile or a musty smell near a baseboard are later signs. If you have two of these, call us before the foundation moves.
Yes. We locate underground and slab leaks with acoustic listening, thermal imaging and tracer gas before any digging happens. On a typical underground leak detection New Braunfels job we mark the spot within a few inches, then open one small area. Most yards need a single 2-foot by 2-foot excavation, not a trench.
