How can I tell if I have a hidden leak?
Signs include a musty smell that does not clear, a damp patch that does not dry, bubbling paint, a warm or soft floor and a water bill that rises without a reason. Any one of these is a reason to have the readings taken.
A hidden leak is often found by its effects rather than by its water. A smell that returns after the room is aired, or a patch on the wall that is cool to the touch, suggests water is moving behind the finish. A bill that rises without a change in use can point to a leak in the supply, and a meter reading can help confirm it.
Check the basics before calling. Find the water meter, and see whether the dial moves when no tap or appliance is running. If it does, close the main and call for a crew, because the leak is likely still flowing.
What do moisture readings actually show?
A moisture meter shows how much water a material holds compared with a dry reference. Readings taken in a grid show where the water is highest and how it spreads, which points the search toward the likely source.
A moisture meter does not show the leak itself. It shows the relative moisture in the material it touches, so readings are compared with dry areas of the same material to find the difference. A high reading near a fixture or a drain is a strong clue, and a high reading far from any fixture may point to water traveling along the framing.
The readings are taken at the same points on each visit, so the trend can be seen. A reading that falls over the visits shows the drying is working. A reading that stays high or rises shows that water is still arriving, and the search continues from there.
Does a thermal camera find every leak?
A thermal camera can show temperature differences that point to moisture, but it cannot see through every material or find every leak. The crew uses it to narrow the search and confirms the spot with a moisture meter before opening the wall.
A thermal image shows surface temperature, and a damp area can look cooler or warmer than the material around it, depending on the conditions. Heavy insulation, thick finishes and recent heating or cooling can make the picture harder to read. A camera is a useful first look, not a final answer.
The crew treats the camera as one tool among several, and it writes down what it saw and what it confirmed. If the camera and the meter disagree, the crew says so and explains what it will do next.
How much of the wall has to be opened?
Only enough to reach the leak and the wet material around it. The crew opens small sections where the readings are highest and closes them as the repair is made, so the search does not turn into a large demolition.
The openings are placed to reach the pipe, the drain or the framing, and they are kept as small as the work allows. The crew starts where the readings are highest and works outward only as far as the readings require. Where a wall is opened, the wet material is removed or dried in place, depending on what it is.
Each opening is photographed and recorded. The note tells the owner where the openings were made and what was found behind them, so the repair can be planned without another search.
What should I do after the leak is found?
A qualified tradesperson repairs the leak, such as a plumber for a pipe, a drain specialist for a drain or a roofer for the roof. The crew's note gives the repair person the location and the readings, so the repair can start from the right place.
The repair is the job of a tradesperson who carries out that kind of work. A slow supply leak needs a plumber to cut out and replace the damaged section. A drain leak needs a drain specialist to check the line. A roof leak needs a roofer to repair the flashing or the shingles.
Once the repair is made, the crew can check that the area has dried. The owner receives the final readings, so there is a record of the drying before the walls and floors are closed up.
What moves the cost of hidden leak detection?
How many walls and floors have to be read, how many openings are needed, how long the leak ran and how much material is wet all change the scope. The price is explained and approved on site before any work starts, and no figure is given here.
A leak that is traced to a single wall with one opening is a smaller job than one that has moved through several rooms. The number of readings, the number of openings and the time needed to dry the material all add to the scope, and so does the finish that must be repaired afterward.
The leak repair is priced by the tradesperson who carries it out, and the finish repair is priced separately. The crew explains its scope on site and confirms the price before the first opening is made.
