Non-invasive leak locating for slab leaks, hidden wall leaks, and unexplained water bills. Plumbers & Rooters Inc helps Pasadena and Altadena property owners fix plumbing problems the right way: diagnose first, explain clearly, complete clean work, and leave you with practical options instead of pressure.
Call (626) 807-7717 for same-day scheduling when available, emergency help, or a planned appointment. We serve single-family homes near Bungalow Heaven, hillside properties in Altadena, older Pasadena apartments, commercial kitchens, small businesses, HOAs, and property managers throughout the San Gabriel Valley.
A high water bill with no obvious cause is usually the first clue. The second is often a warm spot on the floor, a damp patch on a wall or ceiling, or a faint musty smell that was not there before. In Pasadena and Altadena's older homes, copper supply lines running through slabs and walls are the most common source — hard water accelerates pinhole corrosion over the decades.
Our job before any repair is finding exactly where the water is coming from, without guessing and without opening up more of your home than necessary. We use acoustic listening equipment and thermal imaging to pinpoint a leak's location, then confirm it before recommending any work.
Watch for a warm spot on an otherwise cool floor — that usually means a hot water line leaking under a slab. Listen for running water when every fixture in the house is off. Check your water meter: if the small leak indicator dial is spinning with everything shut off, water is escaping somewhere in the system, whether or not you can see it yet.
Other signs build more slowly: a slowly climbing water bill over a few months, a musty smell without visible mold, or a section of flooring that feels softer or looks discolored. None of these alone are proof, but together they are worth having checked before a slow leak becomes a bigger repair.
We start with the meter test and a walkthrough of where you have noticed symptoms, then bring in acoustic listening equipment to trace the sound of escaping water through pipe and slab, and thermal imaging to spot temperature differences a hot water leak leaves behind. This lets us narrow the search to a specific area before opening anything up — on a healthy slab, that often means accessing one small spot instead of a whole room.
Once we have located the leak, we explain the repair options: a spot repair if it's an isolated pinhole, or a broader conversation about repiping if the same copper line has leaked more than once. If the leak is under a slab, we walk through the specific options in more detail on our slab leak repair page.
For homeowners, an unexplained water bill spike is usually what prompts the call. Landlords and property managers often come to us after a tenant reports a smell or a soft spot in flooring, and we document what we find clearly enough to support any needed repairs or disclosures. HOAs dealing with a leak in a shared wall or slab need the source identified precisely, since the fix and the responsibility can depend on exactly where the water is coming from.
A leak that is actively pooling, affecting an electrical fixture, or coming from a ceiling above living space is not something to wait on — call our emergency plumber team. A slow leak with no active water damage can usually be scheduled.
We locate leaks precisely so the repair opens up as little of your home as possible — guesswork means unnecessary demolition, and we would rather spend the extra time finding the exact spot. As a Licensed CA Contractor #1055253, we're open 24/7 with no surcharge nights, weekends, or holidays, and our 5.0 Google rating across 61 reviews reflects that care.
A warm spot on the floor, the sound of water running with everything off, an unexplained rise in your water bill, or a musty smell without visible mold are the most common signs.
If the small leak indicator on your meter is moving with every fixture in the house off, water is escaping somewhere in the system. It's worth having checked even if you can't see any damage yet.
No. We use acoustic listening and thermal imaging to locate the leak precisely first, then access only that spot — not entire walls or floors on a hunch.
If water is actively pooling, near an electrical fixture, or coming through a ceiling, call us right away. A slow leak with no active water damage can usually be scheduled.
