How professional leak detection works
Professional leak detection uses acoustic listening devices, thermal imaging cameras, moisture meters, and pressure testing to locate leaks hidden behind walls, under slabs, and underground — without unnecessary demolition.
A small hidden leak can waste 10,000+ gallons per year, promote mold growth, rot structural wood, and drive up water bills. By the time you see a water stain on the ceiling, the damage behind the wall is often much worse.
Our Western Mass plumbers specialize in non-invasive leak detection. They find the exact source, make targeted repairs, and save you the cost and disruption of tearing out walls and floors to hunt for the problem.
Signs you may have a hidden leak
Unexplained increase in water bill
If your water usage hasn't changed but your bill has jumped, you likely have a leak somewhere in your system.
Sound of running water when nothing is on
If you can hear water running through pipes when all fixtures are off, water is going somewhere it shouldn't.
Mold or mildew in unexpected places
Mold growth on walls, ceilings, or in closets often indicates a hidden moisture source — usually a leaking pipe.
Warm spots on the floor
Hot spots on concrete or tile floors can indicate a hot water line leak under the slab.
Cracks in foundation or walls
Water from a slab leak can erode soil and cause foundation shifting, resulting in visible cracks.
Water meter spinning when everything is off
Turn off all water fixtures, then check your meter. If it's still moving, you have a leak between the meter and your home.
