How do I know if I have a hidden leak?
A hidden leak often shows as a damp spot that does not dry, a water bill that rises without a change in use, a soft area in the floor or wall, or a musty smell in one place. A meter that moves with every fixture off is a clear sign that water is escaping somewhere in the building.
Check the water meter before and after a period when no water is used. Record the reading, wait for a set time with all fixtures and appliances off and check again. A change means water is moving through the meter and out of the building.
Look at the floor and the lower parts of the walls in each room. A patch that is cooler than the rest, or a spot that stays damp, is worth reporting, because the leak is often under the floor or inside the wall where the surface shows only the first sign.
Can a hidden leak be found without opening the wall?
Sometimes the leak can be located from readings and the water path, but often the wall or the floor must be opened to reach the pipe. The technician uses the least invasive method first, and opens only the area that the readings point to.
Moisture meters and an infrared camera can show where the water is without any opening. The results are only a guide, and they are confirmed with a reading inside the material where possible. Where a reading is high and the source is not clear, a small opening is made.
Opening a wall is not a decision made lightly, and the technician explains the reason before it is done. The opening is made as small as the readings allow, and it is closed by the trade that does that work once the materials are dry.
What happens to the floor or the wall after a leak is found?
The wet materials around the leak are dried to the goal set at the start, and materials that have lost their strength are removed. The opening is closed only when the readings show the materials are dry, and the repair of the finish is done by the trade that does it.
The drying is recorded room by room, with the readings for each wet material. The record lists the materials that were removed and the ones that were kept, so the repair can be planned on materials that are proven dry.
A floor or wall that looks finished is not always dry inside. The readings are the way to tell, and they are kept for the repair and for any later question about the damage.
Who repairs the leaking pipe?
A plumber repairs the pipe or the drain, after the technician has located the leak and exposed it. The technician does not repair plumbing, and the plumber decides the method of repair and the parts needed.
The plumber can see the leak once the opening is made, and the pipe is repaired or replaced at that point. The location of the leak is recorded so the plumber knows which part of the line to check and which fittings to inspect.
Ask the plumber to show you the repaired section before the opening is closed. A repair that is visible before the wall is covered is easier to check than one that is buried.
What does a hidden leak investigation cost?
This site does not publish prices. The cost of finding a hidden leak depends on how much of the building must be opened, how long the readings take and how much material must be dried and removed. The plumbing repair is a separate charge from the plumber.
The investigation is scoped on site, and the opening and the drying are explained before the work starts. A leak that is found in one place with a small opening costs less to dry than a leak that runs under a slab or through several rooms.
Ask for the scope in writing with the opening, the materials and the drying goal listed. That scope keeps the investigation, the drying and the plumbing repair as separate lines, which makes them easier to compare and to claim.
