WEST PALM BEACH, FL · RESIDENTIAL LEAK DETECTION
Residential Leak Detection in West Palm Beach
A higher water bill, a damp patch that won’t dry out, a sound you can’t place — most homeowners don’t call about a “leak,” they call about something that doesn’t add up. Residential leak detection is how we find out what’s actually happening inside your house, without cutting into walls or floors to go looking for it.

WHAT IT IS
What is residential leak detection?
Residential leak detection is the process of finding a water leak inside or around a home — as opposed to a commercial building or a shared multi-unit system — using equipment that locates the source without demolition. For a single-family house, townhome, or condo, that usually means checking the water meter, testing pressure through the home’s own plumbing, and using acoustic or thermal equipment to trace a leak to its exact spot. Commercial and shared-line systems work differently (multiple units, shared risers, property management involved), which is why residential detection is treated as its own service rather than a smaller version of a commercial job.
WARNING SIGNS
How do I know if my house has a water leak?
A handful of signs show up more often than others in West Palm Beach homes. On their own, none of these prove there’s a leak — but seeing more than one is worth a closer look:
- An unexplained increase in your water bill
- The water meter still moving when every fixture in the house is off
- Wet spots, damp walls, or damp ceilings with no clear cause
- A musty odor or unexplained mold or moisture in one area
- A warm or unusually cool spot on the flooring
- Water stains on walls, ceilings, or baseboards
- The sound of running water when nothing is turned on
- Cracked or lifting flooring near a suspected wet area
- Water pooling somewhere on the property that doesn’t match rainfall
What are the signs of a hidden water leak in a home?
The signs above are the same ones that point to a hidden leak — the difference is there’s no visible dripping pipe to blame. A hidden leak is often behind a wall, under a floor, or beneath the slab, so the first clue is usually the effect (a bill, a smell, a stain) rather than the leak itself.
HIDDEN LEAKS
Hidden water leaks in a home
A leak doesn’t have to be visible to be real. Water can travel along a pipe, follow framing, or move under flooring before it ever reaches a surface you can see — which is why the first wet spot you notice isn’t always where the problem is. This is the most common reason homeowners are surprised by a leak: everything looked fine until the bill arrived or a spot finally showed through the drywall.
Can a leak behind a wall be detected without opening the wall?
Yes, in almost every case. Acoustic listening equipment picks up the sound of water escaping under pressure, and thermal imaging can pick up the temperature difference where water is present. Together they narrow the search to a small area before anything gets opened.
Can a leak under a concrete slab be detected without breaking the entire floor?
Yes. A full slab doesn’t need to come up to find a slab leak — pressure testing and acoustic equipment locate the specific section first. If you want the complete explanation of how that works, see Slab Leak Detection.
WATER METER TEST
How to check for a water leak at home
Before calling anyone, most homeowners can do one simple check themselves:
- Make sure every fixture and appliance that uses water is off — faucets, toilets, washing machine, ice maker, irrigation.
- Find your water meter and note the reading (or check if it has a leak indicator, a small triangle or dial that moves with any flow).
- Wait 15–30 minutes without using any water.
- Check the meter again. If the reading changed, or the leak indicator moved, water is escaping somewhere in the system.
Why is my water meter running when everything is turned off?
It means water is moving through your plumbing somewhere between the meter and your fixtures, even though nothing is in use. That points to a leak in the line itself, rather than a fixture problem.
This test can tell you that water is likely escaping — it can’t tell you where. A moving meter with everything off is a good reason to call a professional, not a diagnosis on its own.
WHERE LEAKS HAPPEN
Common places residential leaks occur
In houses, townhomes, and condos, leaks tend to cluster in a few areas:
- Bathrooms — around toilets, tub/shower valves, and supply lines under sinks
- Kitchens — under-sink supply lines, dishwasher connections, refrigerator ice maker lines
- Laundry areas — washing machine supply hoses and drain connections
- Behind walls — supply lines running through wall cavities between fixtures
- Under floors — pipes running beneath flooring, especially in homes without a slab foundation
- Under the slab — plumbing embedded in or below a concrete foundation, common in many West Palm Beach homes. See Slab Leak Detection.
- Underground supply lines — the line running from the meter to the house. See Underground Leak Detection.
Older homes with original plumbing, and homes with a lot of concealed or embedded piping, tend to see hidden leaks more often simply because there’s more plumbing you can’t see day to day.
THE PROCESS
Residential leak detection process
Every residential visit follows the same core sequence, adjusted for what you’re seeing in your home:
- Initial discussion — a conversation about what you’ve noticed: the bill, the sound, the spot, the smell
- Review of visible symptoms — a walk-through of the areas you’ve flagged
- Water usage / meter observations — confirming whether water is actively moving through the system when it shouldn’t be
- Inspection of accessible plumbing — checking fixtures, connections, and visible lines first
- Pressure testing — isolating which section of the home’s plumbing is losing pressure
- Acoustic detection — listening equipment traces the sound of the leak to a specific area
- Thermal imaging — used where it adds useful information about temperature differences from moving water
- Moisture assessment — checking how far water may have traveled into flooring or walls
- Pinpointing the suspected location — narrowing everything down to where the leak most likely is
- Explaining findings — a clear walkthrough of what was found and what the next step looks like
DETECTION VS. REPAIR
Leak detection vs. leak repair
Leak detection and leak repair are two different steps. Detection finds and confirms where a leak is, without doing repair work — that’s what this service covers. Once the leak is located, you’ll get a clear explanation of what was found and what fixing it would involve, with a real price before anything starts. If you decide to move forward with repair, a portion of what you paid for detection applies toward that repair work. Detection doesn’t obligate you to repair through us — it just means you’re not guessing about what needs to be fixed or where.
WHEN TO CALL
When should a homeowner call a professional?
A slow drip under a sink might be a simple fix. But if you’re seeing a climbing water bill with no clear cause, hearing running water when everything is off, noticing warm spots on the floor, or finding soft drywall, warping floors, or a musty smell that keeps coming back, it’s worth having the source confirmed rather than guessing.
Can a small residential water leak cause serious damage?
A small leak left unaddressed can worsen over time, especially when it’s hidden behind a wall, under flooring, or beneath a slab, since the moisture keeps affecting the surrounding structure the entire time it goes unnoticed. Confirming the source early keeps the problem contained and gives you clear information before deciding on next steps.
If water is actively flooding your home right now, that’s an urgent situation rather than a routine inspection — see our Emergency Leak Detection page for immediate response.

COMMON QUESTIONS
Frequently asked questions
What is residential leak detection?
Residential leak detection is the process of finding and confirming the source of a water leak inside a home, using visual inspection, water usage review, and equipment like acoustic listening devices and thermal imaging, without doing the repair work itself.
How do I know if I have a hidden water leak in my house?
Common signs include a water bill that’s higher than usual with no clear reason, the sound of running water when everything is off, damp or discolored spots on walls, ceilings, or floors, a musty smell, warped flooring, or a water meter that keeps moving when no water is being used.
Can a leak be detected without cutting into walls or floors?
In many cases, yes. Acoustic detection and thermal imaging can often narrow down the likely location of a leak without opening up drywall or flooring, though some situations may still require a small access point to confirm the exact source.
Does a water meter test prove I have a leak?
A water meter test can tell you that water is moving through your system when it shouldn’t be, which suggests a leak. It doesn’t tell you where the leak is — that requires further inspection with the right equipment.
How long does a residential leak detection visit take?
The time depends on the size of the home and how many areas need to be checked. A straightforward case with a clear symptom area typically takes less time than a whole-home inspection with no obvious starting point.
What areas of a home are most likely to have leaks?
Bathrooms, kitchens, laundry areas, and spaces around water heaters are common because of the concentration of fixtures and connections. Leaks also occur behind walls, under floors, beneath slabs, and in underground supply lines running to the home.
Can a leak under a concrete slab be found without breaking the floor?
Slab leaks are typically located using acoustic and thermal methods that trace the leak’s position before any digging or breaking is done. For more detail, see our Slab Leak Detection page.
Will you repair the leak after you find it?
Detection and repair are separate steps. Once a leak is located, you’ll get a clear explanation of what was found and what repair would involve, with a real price before any repair work starts. A portion of the detection cost applies toward the repair if you move forward.
What equipment is used for residential leak detection?
Depending on the situation, equipment can include acoustic listening devices, thermal imaging cameras, and pressure testing tools, used together with a visual inspection and a review of your water usage.
Can old plumbing make leaks harder to find?
Older homes can have more places for a leak to develop and more variables to check, such as aging pipe materials or past repairs, but the same detection methods still apply to narrow down the source.
Is residential leak detection different from commercial leak detection?
Yes. Residential leak detection focuses on single-family homes, condos, and similar residential properties, while commercial leak detection deals with the different plumbing layouts and scale found in business and multi-unit properties.
What should I do before a leak detection appointment?
It helps to note anything you’ve noticed, such as when the sound started, where a damp spot appeared, or when your water bill changed, and to have recent water bills on hand if possible.
Can a small leak really cause serious damage?
A small leak left unaddressed can worsen over time, particularly when it’s hidden behind a wall, under flooring, or beneath a slab, since the surrounding structure keeps absorbing moisture the entire time it goes unnoticed.
What if the leak turns out to be an emergency?
If water is actively flooding a space in your home, that’s treated as an urgent situation rather than a routine visit. See our Emergency Leak Detection page for immediate response.
