An unexplained spike in the water bill, a damp spot on the floor, or the sound of running water with every fixture off are the usual signs of a hidden leak. Long's Plumbing uses diagnostic methods to locate the source in Cupertino, CA homes before cutting into any wall or slab — pinpointing the leak first keeps repair costs tied to the actual fix, not exploratory demolition.\n\nOne documented case in Cupertino, CA involved a homeowner quoted over $20,000 by another company to replace all the plumbing under the house; Long's Plumbing found the real cause was a simple clog, not deteriorating pipes. That same diagnose-before-you-quote approach applies to every leak call in Cupertino, CA.
