About this service
What Slab Leak Detection Woburn MA Really Involves
Slab Leak Detection Woburn MA is a non-invasive diagnostic service that finds water leaks beneath your concrete foundation without tearing up the floor. We pressurize your plumbing system, then use acoustic listening devices and thermal imaging cameras to hear and see where water escapes. A slab leak usually starts as a pinhole leak in copper pipes or under slab pipe corrosion in older homes. Left alone, it can cause foundation water damage, cracked slab, and mold. We pinpoint the leak to within inches before any concrete cutting saw touches your floor.
Woburn's housing stock includes plenty of mid-century ranches and capes with original copper pipes now hitting 60-plus years of service. Those pipes corrode from the outside in, and our freeze-thaw cycles push stress fractures wider every winter. If you have noticed a high water bill, warm floor spots, or the sound of running water when everything is off, you need under slab leak detection Woburn MA. We also help buyers and sellers with slab leak detection for older homes in Woburn MA during real estate transactions.

What's included
What Our Slab Leak Detection Includes
Every slab leak detection job includes a full system pressure test, acoustic and thermal scanning, and a written report with our findings. We also mark the leak location on your floor and provide repair options. If you need concrete cutting or pipe replacement, we quote that separately after you approve the detection results.
Acoustic and Thermal Scan
We walk your floor with acoustic listening devices and a thermal imaging camera. These tools pinpoint the leak to within a 6-inch radius.
Moisture Mapping
We use moisture meters to map the extent of water damage under your floor. This helps determine if mold remediation is needed.
Written Report with Photos
You get a PDF report with our findings, photos of the marked leak location, and pressure test results. This documentation supports insurance claims.
Repair Estimate
If you want us to fix the leak, we provide a written estimate for the repair. That includes concrete cutting, pipe replacement, and patching.
How it works
Our Slab Leak Detection Process
When you call 781-452-3771, we ask about your water bill, any warm spots on the floor, and the age of your plumbing. That five-minute conversation helps us bring the right tools. We schedule a same-day or next-day visit, depending on your urgency.
Our licensed technician arrives in a marked van and starts with a whole-house pressure test. We isolate the domestic water system from the sewer line, then pressurize to 80 psi. A slow drop on the gauge tells us there is a leak. This step takes 20-30 minutes.
We walk the floor with acoustic listening devices and a thermal imaging camera. The acoustic wand picks up the hiss of water escaping under pressure. The thermal camera shows temperature differences caused by hot water leaks. Together, they narrow the search to a 6-inch zone.
Before we mark the floor, we confirm the leak location with a second method, often a moisture meter or video pipe inspection camera. We spray-paint a circle on the slab and photograph it for your records. You get a written report with our findings and recommended repair options.
If you approve the repair, we can often complete it the same day. For under slab pipe replacement, we use concrete cutting saws to open a small access hole, then swap the damaged section with PEX tubing or copper. We backfill, patch with concrete patch mix, and retest the line before we leave.

Tools & methods
Tools and Methods We Use
Acoustic Listening Devices
We use these to hear the sound of water escaping under pressure. They work through concrete and help pinpoint the leak to a 6-inch area.
Thermal Imaging Cameras
Fluke thermal cameras show temperature differences caused by hot water leaks. We use them to confirm acoustic findings and find leaks in low-noise environments.
Electronic Leak Detection Wands
These wands detect moisture and pressure changes in walls and floors. We use them for hard-to-reach areas and to confirm leak locations.
Pressure Testing Gauges
We pressurize your system to 80 psi and watch for drops. This test confirms a leak exists and helps isolate the affected line.
Video Pipe Inspection Cameras
RIDGID and Milwaukee cameras let us see inside pipes. We use them to check for cracks, corrosion, and blockages in sewer lines.
Moisture Meters
We map the extent of water damage under your floor. This helps determine if mold remediation is needed and supports insurance claims.

After: We found a pinhole leak in a copper pipe 14 inches under the kitchen floor. We cut a 12-inch access hole, replaced the section with PEX tubing, and patched the concrete. The water bill returned to $85 the next month.

Commercial Leak in Mishawum
A property manager noticed water pooling in a commercial lobby. The building had a slab leak that was flooding the floor after hours. Tenants were complaining about moisture.

We use acoustic listening devices to trace the sound to its source. Then we isolate the line and confirm with a pressure test.
