Leak detection is the process of pinpointing a hidden water leak inside walls, ceilings, under concrete slabs or underground, using tools such as acoustic listening equipment, thermal imaging, moisture meters and pressure testing, so the repair opening is as small as possible.
Why leak detection matters in Boca Raton
Most Boca Raton homes are built on concrete slab foundations with water lines running in or under the slab. When one of those lines develops a pinhole, the water has nowhere obvious to go. It can spread under flooring, wick into drywall or simply drain into the soil while your meter keeps spinning. Without detection equipment, finding the leak can mean breaking up far more tile than necessary.
Condo owners face a different challenge: a stain on your ceiling could come from your unit’s lines, the unit above or a building pipe. Locating the source first helps settle responsibility with the association.
Signs of a hidden water leak
- A water bill noticeably higher than usual with no change in habits
- The water meter moves when all fixtures are off
- Warm or damp spots on tile floors (often a hot water line under the slab)
- Cracked or lifting tile, swelling baseboards or musty odors
- The sound of running water when nothing is on
- Ceiling stains or bubbling paint
- The water heater runs more than usual

How plumbers find hidden leaks
| Tool or method | What it does |
|---|---|
| Meter and pressure testing | Confirms a leak exists and isolates whether it’s on the hot side, cold side or irrigation. |
| Acoustic listening devices | Amplify the sound of water escaping a pressurized line through concrete or soil. |
| Thermal imaging | Shows temperature differences, which is especially useful for hot water slab leaks. |
| Moisture meters | Measure moisture in drywall, baseboards and flooring to map affected areas. |
| Line tracing | Locates the path of pipes under slabs before any cutting. |
What happens after the leak is found?
Once the leak is located, the plumber explains the repair options. For slab leaks, the choices commonly include a direct spot repair through the slab, rerouting the line through walls or the attic, or, if the pipes are failing in several places, repiping part or all of the home. The plumber can explain the trade-offs on our pipe repair and repiping page.

What affects the cost of leak detection?
- Size of the home and how many lines must be tested
- Whether the leak is under slab, in a wall, in a ceiling or underground outside
- Equipment required and the time to isolate the leak
- Whether the repair is quoted separately from detection
Insurance and documentation
Coverage for leak detection, access and resulting water damage varies by homeowners or condo policy. Ask the plumber for a written report of where the leak was found and what caused it, and take photos before repairs. Your insurer may ask for both.

Frequently asked questions
How do I know if I have a slab leak?
Common signs are a warm spot on the floor, the sound of running water, a spinning water meter with everything off, cracked tile and a jump in the water bill. A plumber can confirm it with pressure testing and acoustic equipment.
Can leaks be found without tearing up floors?
In most cases, yes. Plumbers use acoustic listening, thermal imaging and pressure testing to pinpoint the leak so only a small access opening is needed.
How do I check my water meter for a leak?
Turn off every faucet and water-using appliance, note the meter reading or watch the leak indicator, and wait 30 minutes to an hour without using water. If it moved, water is going somewhere.
Does homeowners insurance cover slab leaks?
It depends on your policy. Some cover access and resulting damage but not the pipe itself. Check with your insurer and keep the plumber’s written findings.
Is it a pipe leak or a pool or irrigation leak?
A plumber can isolate the house plumbing from irrigation and other lines with valve and meter tests to narrow down where the water is going.
