Hidden Leaks

Hidden Leak Detection: what it covers

Quick answer

Hidden leak detection is the process of finding water that escapes inside a wall, under a floor or above a ceiling without an obvious stain. Buffalo Water Damage Restoration uses moisture readings and a careful look at the building to trace the leak in Buffalo and Erie County, and to open only where needed.

Many water problems never show as a puddle. A supply line that weeps inside a wall, a drain that leaks under a floor or a roof flashing that lets water into the attic can run for weeks before anyone sees a stain. What the homeowner notices first is usually a smell, a damp patch that does not dry, a bubble in the paint, a warm or soft floor or a water bill that has risen for no clear reason.

Finding that water takes more than a glance. A crew uses moisture meters to read the walls, floors and framing, and it may use a thermal camera to see differences in temperature behind the finish. The readings are compared across the building, and the pattern points to the leak. The crew then opens the finish only where the readings say the water is, so the search does not turn into a demolition.

If you have a damp spot, a smell or a bill that does not add up, call (833) 490-5225. A crew is sent as soon as one is free. The first visit takes readings across the suspect area and the rooms around it, and the owner is told what the readings show and what is still unclear before any wall is opened.

Warning signs

Signs you need hidden leak detection

Do not open a wall or floor yourself to look for a leak, because a pipe or wire may be behind the finish. Switch off the power to the area before any opening is made near an outlet or a fixture. If you smell gas, leave the building and call the gas utility from outside. Do not drill into a wall that you suspect has a supply line in it.

  • A musty smell in one room that does not clear, or that gets worse after rain or a shower
  • A damp or cool patch on a wall or floor that stays wet for days
  • Paint that bubbles, peels or stays soft in one spot
  • A floor that feels warm or soft in one area, or a board that has begun to lift
  • A water bill that has risen without a change in use
  • White crust, called efflorescence, on masonry or a wall that stays damp
Our process

How our hidden leak detection visit works

  1. Listen to the history and look at the building

    The crew asks when the smell, the stain or the bill first appeared, and what has changed in the house since then. It looks at the fixtures, the drains, the water heater and the outside walls near the suspect area.

  2. Take moisture readings across the area

    A moisture meter is used on the wall, the floor and the framing in a grid, so the crew can see where the moisture is highest and how it falls away. The readings are logged with their location, and the same points are checked again on later visits.

  3. Use a thermal camera where it helps

    Water that is evaporating or that is colder than the material around it can show as a difference in temperature. A thermal camera helps narrow the search, and the crew confirms what it sees with the moisture meter rather than relying on the picture alone.

  4. Open the finish at the points that matter

    The wall or floor is opened in small, neat sections where the readings are highest and the likely source is. The openings are placed to reach the pipe or the framing, and they are photographed and recorded.

  5. Report the likely source and the repair it needs

    The note gives the owner the readings, the photographs and the likely source, and says plainly where the crew is sure and where it is not. The repair to the pipe, drain or roof is made by the qualified tradesperson, and the openings are closed once the area is dry.

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.

Options

Types and options for hidden leak detection

Slow leak in a plaster or drywall wall

A supply line or a drain fitting inside a wall can leak at a slow rate for a long time. The water runs down the stud bay or along the plate, and it shows as a damp patch low on the wall or as a stain near a fixture. The crew reads the wall in a grid and opens the spot where the readings are highest.

Leak under a cellar floor or slab

A drain or supply line under a cellar floor can leak into the soil below. The floor may show as damp in one place, or as a rise in the moisture in the walls next to it. The crew reads the floor and the walls and advises on whether the floor needs to be opened.

Leak above a ceiling or into an attic

Water that enters from a roof valley, a flashing or a plumbing vent can run along the framing before it shows on a ceiling. The crew checks the attic and the ceiling together and reads the framing near the stain.

Erie County

Why hidden leak detection is different in Western New York

Hidden leaks are hard to find in plaster and lath walls, which can hold water in cavities that a moisture meter reads only near the surface. The crew reads several depths and checks the framing where it can reach it.

A wall that is damp only in winter can point to a leak that is hidden by the cold. Heat and cold change how water moves through a wall, so the crew asks about the season when the problem was first seen and records the readings across the year.

Across Erie County, the buildings and their pipes differ from one property to the next. The crew reads the building in front of it, rather than assuming the layout matches the plans of a similar house on the same street.

FAQ

Hidden Leak Detection FAQs

How do I know if there is a leak behind the wall?

A musty smell, a damp patch that does not dry, bubbling paint and a rising water bill are common signs. Moisture readings show whether the wall is wet, and the crew can trace the water from there.

Can a leak be found without opening the wall?

Often the readings and the thermal look narrow the search enough to open a small, targeted section. Some leaks cannot be confirmed without an opening, and the crew says so when that is the case.

Is a thermal camera enough to find a leak?

It is a useful first look, but it does not find every leak. The crew confirms the spot with a moisture meter before any wall is opened.

Can I check my water meter myself?

Yes. Note the reading, make sure no tap or appliance is running, and check again after an hour. If the dial still moves, close the main and call for a crew, because the leak is still flowing.

Who repairs the leak once it is found?

A plumber, drain specialist or roofer repairs the leak, depending on where it is. The crew's note gives that tradesperson the location and the readings.

Does insurance cover a hidden leak?

That depends on the policy and the cause of the leak, and the insurer decides. Some policies treat a long slow leak differently from a sudden one. Keep the readings and the photographs, and ask the insurer what it needs.

Will the finish be damaged when the wall is opened?

Some finish is opened to reach the leak, and it is repaired afterward by a drywall or plaster person. The openings are kept small and photographed, so the repair can be planned.
