Some leaks announce themselves. Others hide in walls and under slabs until the damage shows. Here is how to confirm a hidden leak and what a professional repair visit looks like.
A burst pipe is obvious. A leak behind a shower wall or under a slab is not. You might notice a higher bill, a musty smell in a closet, or a faint hiss at night, and wonder whether you really have a problem. This guide explains how to confirm a hidden leak yourself, how to choose emergency leak repair near you, and what actually happens during a professional detection and repair visit.
If water is already pouring out, skip ahead: our leak-by-leak emergency response guide tells you what to shut off for each type of leak.
Signs a Hidden Leak May Be Growing
- A water bill that jumps without a change in habits
- Musty odors in cabinets, closets or along baseboards
- Paint bubbling, drywall softening or baseboards swelling
- Floor tiles that sound hollow or start to lift
- A warm area on a tile or concrete floor
- The sound of running water when nothing is on
- Water pressure that seems lower than it used to be
The Water Meter Test
This is the single most useful check a homeowner can do.
- Turn off every fixture, the dishwasher, washing machine, ice maker and irrigation.
- Find your water meter, usually in a box near the street.
- Look at the leak indicator, a small triangle or dial that spins with very low flow.
- If it’s moving, write down the reading and wait an hour or two without using water, then check again.
- To narrow it down, close the main valve at the house. If the meter stops, the leak is inside the home. If it keeps moving, the leak is likely between the meter and the house.

Is It an Emergency?
A hidden leak becomes urgent when:
- The meter is moving quickly
- Water is visible on floors, walls or ceilings
- There’s a hot spot on a slab floor, which suggests a hot water line under the concrete
- Mold or a strong musty smell is developing
- You’re on a well and the pump is cycling on and off constantly with no water in use
In Central Florida’s humidity, wet building materials can start growing mold quickly, so don’t let a confirmed leak sit for long.
Choosing a Leak Repair Company
When you call, ask:
- Are you licensed and insured? Can I look up the license?
- Do you do leak detection, or only repairs?
- How is the visit priced, and when will I get the repair price?
- Can you come now, or what is the earliest arrival window?
- Can you provide documentation for my insurance claim?
What Happens During the Visit
1. Interview and inspection
The technician asks about symptoms, history and your meter test, then inspects visible plumbing, fixtures and the water heater.
2. Isolating the leak
By closing valves and checking pressure, the plumber determines whether the leak is on the hot side, the cold side, a fixture, or the main line.
3. Pinpointing with equipment
Professional leak detection uses tools such as acoustic listening devices that hear water escaping, thermal imaging that shows temperature differences, moisture meters, and pressure testing. These narrow the search so the access opening can be small. Our guide to leak detection techniques explains each method.
4. Containment
If water is actively causing damage, the plumber contains it first: isolating the line, capping it, or setting up a temporary fix so the rest of the house has water.
5. Repair options
You’ll get a clear explanation and an upfront price before work starts. Options depend on location:
- Replace a failed fitting, valve or section of pipe
- Repair a slab leak through the concrete
- Reroute a line through walls or the attic to bypass the slab
- Consider repiping if the pipes are failing in multiple places
6. Testing and documentation
The repair is tested under pressure, the meter is checked again, and you receive documentation of the source and the fix.
After the Repair
- Dry wet materials promptly; bring in a water mitigation company for larger areas.
- Have drywall, flooring or concrete patched once everything is dry.
- Watch the meter and the water bill for the next cycle to confirm the problem is solved.
