“We felt an unexplainably warm spot on our hallway linoleum right outside our bedroom. Our water heater was cycling constantly even with nobody using hot water. Precision came out with acoustic microphones and an infrared thermal scanner, mapped the buried line under the slab, and marked the exact pinhole leak location within a 4-inch square. Our plumber cut only one small patch instead of tearing open the entire hallway floor.”
Slab Leak Detection in West Whittier
One of the most common reasons West Whittier homeowners call about a possible slab leak is a floor that suddenly feels warm. Here is what that can mean and how we help you find out.

Signs worth investigating
Whether your property is in West Whittier or elsewhere in Whittier, slab leaks tend to reveal themselves through indirect clues:
- Water use that keeps rising with no change in habits
- A water meter that moves with every fixture off
- Warm or damp areas on the floor
- Musty odors or moisture at the base of walls
- The sound of running water when nothing is on
Any one of these can have another cause. Several together — or a meter that will not stop moving — are a good reason to call. See 10 warning signs of a slab leak for more detail.
When a warm floor is a warning sign
A leak on a hot-water line beneath the slab can warm the floor above it. People often notice it barefoot, or when a pet starts favoring one spot. But warmth has other explanations too, so it helps to think it through:
- Is the warm area new, or has it always been there?
- Is there a heating duct, radiant heat, or appliance nearby?
- Does it line up roughly with a path between the water heater and a bathroom or kitchen?
- Has your water heater been running more, or your gas or electric bill risen?
- Does the water meter move when all hot and cold water is off?
A new, persistent warm area with no obvious source — especially alongside higher water or energy use — is worth investigating. Our under-slab water leak detection service can isolate the hot-water line and narrow down the leak area.
How we help
We start with a conversation about what you are noticing, check for simpler explanations, then isolate lines and use surface-based methods to narrow down where water is escaping. You get a plain-language explanation of what we found and what your options are. Learn more about slab leak detection or our leak location and diagnostic assessment.

What West Whittier Clients Say
Recent non-destructive leak-location assessments completed for homeowners throughout West Whittier.
“I could hear faint rushing water in the wall behind our laundry room late at night, but our water pressure seemed normal. I was terrified of foundation cracking. Precision isolated the manifold, confirmed continuous 0.4 GPM loss through the sub-slab copper loop, and pinpointed the leak point without breaking concrete. Extremely professional, calm, and saved us thousands in exploratory demolition.”

Questions From West Whittier Property Owners
Call (562) 358-3136 with your street address and a short description of the problem. We will confirm whether we can schedule a visit at your property and talk through the next step.
Thermal imaging can show warm patterns that may indicate a hot-water leak, but it does not detect water directly. We treat it as supporting evidence and confirm findings with other methods.
If water is actively damaging your home and you shut off the main supply, follow your water heater manufacturer's guidance — many recommend turning the heater off or to a vacation setting. If unsure, ask a plumber.
Detection and repair are separate services. Our focus is locating the leak and explaining what we find. Ask us what is included when you call.
