A hidden leak rarely announces itself with a puddle. It works quietly behind a wall for weeks — and by the time you see it, the repair has tripled in size. Here is what we check first on every diagnostic visit.
Watch your water meter
Close every tap, note the meter reading, and check it again two hours later without using any water. If the number moved, water is going somewhere it shouldn’t.
Trust your nose
A persistent musty smell in one room — especially near the floor — is often the first perceptible sign of moisture trapped in a wall or under flooring.
Look for cold spots and stains
Run your hand along the wall. A section that stays cold and slightly damp, or paint that bubbles and yellows, usually sits close to the leak itself.
Listen at night
Pipes are quieter competition-free. A faint hiss or drip behind a wall when the house is silent is worth investigating.
Check the pressure
A drop in water pressure at one fixture — not all of them — often points to a localized leak or a corroded section of pipe.
When to call
If two of these signs show up together, stop guessing. A professional acoustic and thermal diagnostic locates the leak precisely, so we open one small section of wall instead of three.
