Denton County Leak Detection Experts

Water Leak Detection Services

Hidden leaks waste water and cause silent damage. Haltex Plumbing's advanced detection technology finds leaks behind walls, under floors, and underground — without demolition.

Advanced Water Leak Detection for Denton County

Water leaks are deceptively destructive. A leak as small as 1/8 inch in diameter can waste 250 gallons per day — over 7,500 gallons per month — and that is just the water you are paying for. The real damage happens silently: behind walls where mold colonies form, beneath floors where subfloor material warps and deteriorates, and underground where erosion undermines your foundation. According to the EPA, the average American home loses 10,000 gallons per year to leaks, but in Denton County — where hard water, expansive clay soil, and temperature extremes stress plumbing systems — that number is often much higher.

Haltex Plumbing provides comprehensive water leak detection services across Denton, Argyle, Flower Mound, Highland Village, McKinney, Sanger, Krum, and Corinth using non-invasive technology that finds leaks without tearing open your walls or floors. Our investment in advanced detection equipment means we can locate hidden leaks quickly and accurately, saving you the expense and disruption of exploratory demolition.

Non-Invasive Detection Technology

Our leak detection toolkit includes several complementary technologies that, used together, allow us to find virtually any leak in any location:

Acoustic Listening Devices: Pressurized water escaping through a pipe produces sound — a hiss, rush, or vibration that travels through the pipe wall and surrounding material. Our electronic amplification equipment detects and localizes these sounds even through concrete slabs, drywall, and soil. This is our primary tool for slab leaks and underground supply line leaks.

Thermal Imaging (Infrared Cameras): Leaking water changes the temperature of surrounding materials. Our infrared cameras detect these temperature differentials through walls, floors, and ceilings, revealing the path of hidden water flow. Thermal imaging is particularly effective for hot water line leaks, where the temperature contrast is most pronounced, and for identifying the extent of water damage from any leak.

Moisture Meters & Mapping: Professional-grade moisture meters measure the moisture content of building materials without damaging them. We create a moisture map of affected areas, showing exactly where water has spread behind walls, under floors, and above ceilings. This mapping is invaluable for insurance claims and for ensuring that all affected areas are properly dried and restored after repair.

High Water Bill Investigation

One of the most common reasons Denton County homeowners call us is a water bill that has suddenly spiked or gradually climbed without explanation. We perform a systematic investigation that includes meter readings, whole-house pressure testing, fixture-by-fixture inspection, and outdoor irrigation system evaluation. In many cases, the leak turns out to be in a location the homeowner never suspected — a toilet flapper wasting 200 gallons per day, a slow slab leak, or an underground supply line crack between the meter and the house.

Underground Leak Detection

Leaks in underground water supply lines — the pipe running from your water meter to your house — are common in Denton County due to soil movement and corrosion. These leaks often go undetected for months because the water drains into the surrounding soil instead of pooling visibly. We use a combination of acoustic detection and pressure testing to locate underground leaks and then repair or replace the affected section of line.

Behind-Wall & Under-Floor Leaks

Supply line leaks behind walls and under floors cause the most insidious damage because they are hidden. By the time you see water stains on a ceiling or smell mold behind a wall, the leak has often been active for weeks or months. Our thermal cameras and moisture meters detect these leaks early, before visible damage appears, and we can open the wall at the precise leak location rather than performing costly exploratory demolition.

Signs You Have a Hidden Water Leak

• Unexplained water bill increase — the most reliable indicator. Check your water meter when no water is being used; if the dial is moving, you have a leak.
• Water stains on ceilings or walls — discoloration or bubbling paint often indicates a supply line leak above or behind the affected area.
• Musty or mold smell — persistent musty odors near walls, floors, or cabinets suggest hidden moisture promoting mold growth.
• Warped or buckled flooring — wood, laminate, or vinyl flooring that is warping or lifting can indicate a leak beneath the floor.
• Low water pressure — a leak in your supply line diverts water and reduces pressure at your fixtures.
• Running water sounds — hearing water flowing when nothing is turned on is a strong indicator of a pressurized line leak.

Our Leak Detection Process

Step 1: Water Meter Check

We start at the water meter to confirm a leak exists and measure its approximate flow rate. This also helps us determine whether the leak is inside the house or in the underground supply line between the meter and the house.

Step 2: Systematic Search

Using acoustic, thermal, and moisture detection equipment, we work through your home systematically — checking supply lines, drain lines, fixture connections, and appliance connections. We narrow the search area progressively until we pinpoint the leak location.

Step 3: Diagnosis & Options

Once located, we explain the type and severity of the leak and present repair options with transparent pricing. We provide moisture mapping data for insurance documentation when applicable.

Step 4: Repair

Many leaks can be repaired the same day as detection. We open the wall, floor, or slab only at the precise leak location, make a permanent repair, and pressure-test to verify the fix before patching.
