A hidden water leak can silently destroy your home for weeks before you notice. We use moisture mapping, thermal imaging, and acoustic technology to track down leaks behind walls, under floors, and in ceilings — without tearing anything apart.
Residential leak detection is the process of locating hidden water leaks inside your home using professional-grade technology. Unlike a plumber who might need to cut open walls to find a problem, a leak detection specialist uses tools like thermal cameras, moisture meters, and acoustic amplifiers to see and hear what's happening behind surfaces — without causing any damage.
Water leaks in a home don't always announce themselves with a dramatic flood. More often, they're slow and hidden: a pinhole leak in a supply line behind a bathroom wall, a failed fitting under a kitchen sink, a deteriorating drain line seeping into your subfloor. These leaks can run for weeks or months, quietly driving up your water bill, feeding mold growth, and weakening the structural integrity of your home.
At Exact Leak Detection HTX, we find the source — not just the symptom. A water stain on your ceiling tells you something is leaking. We tell you exactly what, exactly where, and give you the documentation to prove it.
Don't ignore these warning signals — early detection saves thousands.
Your usage habits haven't changed, but the bill keeps going up. Even a small leak can waste 10,000+ gallons a month. If your bill has spiked without explanation, there's water going somewhere you can't see.
Yellowish-brown stains, bubbling paint, or peeling wallpaper are classic signs of water intrusion. The stain might be far from the actual leak — water travels along pipes, framing, and gravity before showing itself.
A persistent damp, earthy smell — especially in bathrooms, kitchens, or closets on exterior walls — means moisture is trapped somewhere. In Houston's humidity, even a small hidden leak can produce mold growth in days.
Turn off every water fixture and appliance in your home, then check your water meter. If it's still moving, water is leaving your plumbing system somewhere. This is one of the most reliable DIY indicators of a hidden leak.
Hardwood that's cupping, laminate that's lifting at the seams, or tile with loose grout — these all point to moisture underneath. Water under flooring causes expansion and deterioration that gets worse every day.
If the pressure throughout your home has decreased — not just one faucet — it could mean a supply line is leaking and diverting water before it reaches your fixtures. The bigger the pressure drop, the bigger the leak.
Multiple technologies. One precise answer.
We systematically scan your walls, floors, and ceilings with professional moisture meters to map exactly where water is present and how far it's spread. This creates a clear picture of the affected area before we even start looking for the source.
Our FLIR infrared cameras reveal temperature differences behind surfaces that are invisible to the eye. Leaking water changes the temperature of surrounding materials — we can see wet areas inside walls, trace water trails, and identify the path from source to symptom.
Using electronic amplification, we listen for the sound of pressurized water escaping a pipe. Supply line leaks produce distinctive hissing or rushing sounds that our equipment can detect through walls, floors, and concrete — pinpointing the exact location of the breach.
You receive a comprehensive written report with photos, thermal images, moisture readings, and our professional findings. This gives your plumber the information they need for targeted repairs, and gives you documentation for insurance if applicable.
Houston's combination of climate, soil, and building practices creates a perfect storm for residential water leaks. The city's extreme humidity means even small leaks can escalate into mold problems quickly — what might dry out in Arizona becomes a mold colony in Houston within 48 to 72 hours.
The expansive clay soil throughout the greater Houston area shifts constantly with rainfall and drought cycles. This soil movement stresses plumbing connections, cracks pipes, and disrupts fittings — especially in homes built on slab foundations, which account for the vast majority of Houston's housing stock.
Then there's the age factor. A huge number of Houston-area homes were built between the 1970s and 1990s, using copper supply lines and cast iron drain lines that have reached or exceeded their expected lifespan. Copper corrodes. Cast iron rusts and deteriorates. The pipes your home was built with are working on borrowed time.
That's why proactive leak detection matters here more than most cities. A Houston homeowner who catches a leak early avoids the cascading damage — mold remediation, flooring replacement, drywall repairs — that comes from letting it run.
Straightforward pricing. No surprises. Report always included.
Slab leak investigations: $450–$550 (additional equipment and time required)
After-hours & emergency service: +$150
No leak found? You still get the full report and peace of mind.
Standard residential leak detection at Exact Leak Detection HTX starts at $325. This includes a comprehensive investigation using moisture meters, thermal imaging, and acoustic equipment, plus a detailed report with photos and findings. Slab leak investigations are $450–$550 due to the additional complexity.
Common signs include an unexplained increase in your water bill, water stains on ceilings or walls, musty odors, peeling paint or bubbling wallpaper, damp or discolored spots on floors, and the sound of running water when everything is turned off. If your water meter continues to move when no water is being used, that's a strong indicator of a hidden leak.
We use a combination of professional-grade tools: moisture meters to map the extent of water intrusion, FLIR thermal imaging cameras to detect temperature anomalies caused by leaking water, acoustic listening devices to hear pressurized water escaping pipes, and pressure testing equipment to isolate specific plumbing lines. This multi-tool approach ensures we find the leak, not just the symptoms.
No. Our entire approach is non-invasive. We use technology that works through walls, floors, and ceilings to find leaks without cutting, drilling, or demolishing anything. The goal is to pinpoint the exact leak location so that any necessary repairs are as targeted and minimal as possible.
Most residential inspections take 1 to 2.5 hours, depending on the size of the home, the number of potential leak areas, and the complexity of the plumbing system. We don't rush — thorough detection now saves you from repeated repairs later.
Yes. Moisture meters can detect elevated moisture levels through drywall, and thermal imaging cameras can reveal temperature differences caused by water flowing behind walls. We can typically identify both the general area and specific pipe causing the problem without opening up the wall.
Yes, every inspection includes a detailed written report with photos, thermal images, moisture readings, and our findings. This report is useful for your own records, for your plumber when making repairs, and for insurance claims if water damage is involved.
The sooner you find it, the less damage it does. Call for a same-day or next-day inspection.
