Good To Know

Leak detection FAQs

How do I know if I have a hidden leak?
Common signs are an unexplained jump in your water bill, damp or stained walls and ceilings, a musty smell, low water pressure, or the sound of running water when nothing is on. If you notice any of these, call Watson's at (212) 368-3434 to locate it before it spreads.
Can you find a leak without tearing up walls?
In most cases, yes. Our licensed master plumbers pinpoint the source first so any access is as small and targeted as possible, which keeps the repair cleaner and the cost down.
Why does a small leak matter?
Even a slow leak can rot framing, ruin drywall, grow mold and quietly run up your water bill. Catching and repairing it early is far cheaper than the water damage it causes if ignored.
Do you repair the leak the same day you find it?
Often, yes. Once we locate the source we give you an honest up-front price and, for most common leaks, repair it on the spot across Manhattan, the Bronx, Brooklyn and Queens.
