In this technical warming world, finding the solution to eliminate the energy loss inside and outside the home is prominent.

As a homeowner, you could save hundreds of dollars by being a pro while inspecting and checking your home or property.

Thermal leaks and energy loss are possible anywhere in and around the home but finding where they are in the solution to rectifying the issues.

It will not only afford you a comfortable and energy-efficient home but also reduce the overall energy loss and expensive bills.

We can’t see these insulation and thermal leaks in the home with a naked eye. But thermal leak detectors will help you in spotting the hot/cold spots in your property or home so you can take resolving actions quickly.

Now you know why building inspectors and contractors are preferred to use thermal imaging cameras for leak detection.

These thermal imaging leak detection cameras can see the plumbing areas or pipes under the wall or behind the building to find the leaks before they developed a real problem.

Why Thermal Imaging Camera for Leak Detection

Thermal imaging technology measures even the small temperature changes due to moisture.

Most of the complicated or advanced tool projects a colored image but this and the monochromatic levels show the wet areas as darker. This is not enough to clear the leaking problems.

However, it is not hard to spot the wet areas but every time you can’t find where the water is leaking.

After you find the wet area on a ceiling, you should find out what causes this leak. This may because of the hole in the roof, or plumbing leaks in the upstairs.

If the wet area spotted in the basement, there may be water flowing through the floor or running via a window or cracking the walls.

A thermal imaging camera can help in these situations to find the exact source of water leaks.

Thermal imaging cameras for home inspection not only detect the source of leaks but as a building inspector, you need to use your tool to find the moisture in every room.

Most of the time, there is no indication for the moisture infiltration until it becomes a serious problem. But thermal leak detection can found it early and saves the homeowner’s expenses.

Anyone can find roof leaks with an infrared water leak detectors.

Leak Detection Using Thermal Camera

A best thermal imaging camera for water leaks can detect even behind the walls or hidden plumbing areas using any of these two methods:

1) The trapped moisture in an area shows colder than its surroundings.

2) In a heated room, the moisture takes a long time to cool down so thermal imaging camera can measure this higher temperature and shows up with color accordingly.

Thermal Imaging Cameras for Water Leak

Within a few steps, you can detect the water leaks in your home or property using an infrared water leak detector.

Step 1:

Turn on the thermal camera and set the temperature sensitivity range. This value based on the indoor temperature and outdoor ambient temperature. The selected range has to cover the maximum and minimum natural temperature and room for the difference.

Step 2:

Start scanning room from one wall and continue your work around the room and end at the ceiling. Be attentive while scanning windows and bathrooms.

Based on the environmental conditions, water in the wall will either cool or warm than the normal temperature of used construction materials. If you use the camera with a color display, you will get temperature variations in an image with different colors.

Step 3:

If you assume the water leak is due to plumbing, turn on the water supply to that area. If you suspect it as a roof leak, you have to use a thermal camera during rainfall.

Step 4:

Focus on the suspected leak areas and observe the thermal image. The temperature variation of water is because of the evaporation process.

A winding temperature difference detected in the ceiling is a good sign of water leak. A temperature difference measured under windows and bottom of wall framing also a good indicator of a leak.

Step 5:

To confirm the moisture in the wall use the moisture meter. You have to set the meter to wall type and face it against the wall. If you detect the moisture content on and above 18%, it is a problem.

Thermal Imaging Cameras for Air Leak

Using a thermal imaging camera for finding the origin of air leaks needs few additional fixings than finding insulation problems.

To force the airflow through cracks and holes on the wall, have to change the air pressure of indoor related to outdoor.

The warmer or colder airflow from the outdoor to the room through cracks and holes can be located on a thermal imaging camera and the inspector found the sources of these air leaks.

You can use the blower door equipment to force the air into a room via holes and cracks. This process creates perfect conditions for airflow on leaky spots and these spots are displayed in a thermal image.

You can use exhaust fans and ventilation systems of home instead of a blower to create similar conditions and gather leaking spots details.

Areas To Check

Before looking for air leaks, it is important to decide what areas to examine to finish the process within time. An infrared camera is helpful to know where to start finding the air leaks.

During the blower door test, you can feel the air leaks with the hand. While cold weather, the places which have insufficient insulation may be visible because of the temperature change in those specific areas.

The important areas to check while thermal leak detection.

Building inspectors can start their detection with light fixtures, basement rim joists, windows and doors, ductwork, kitchen soffits, cellar doors, etc. or any suspected water or air leaking area or the place where insulated is lacking.

How to Choose the Best Thermal Imaging Camera for Leak Detection

Now after knowing the importance and necessity of thermal camera for leak detection, you have to decide which thermal imaging camera model will be suitable for your work.


If you’re looking for the infrared water leak detector for personal need and not for daily use, then you can choose some cheap thermal imaging camera that would offer basic thermal imaging and detection.

Otherwise, for professional use as a building inspector, you will need accurate results and crystal clear images; you should rely on some high-end thermal cameras with high resolution, sensitivity, and durability to fit for regular usage.


Consider where you will use this device. Those who have to work in different environmental conditions and places need a strong, rugged, and heavy-duty thermal camera with decent drop protection.

Custom Report

Homeowners won’t look for this feature but for service providers it is inevitable. They must submit the final report to their customers so the camera with sharing and reporting software would be a great choice for them.

Intuitive and User-friendly

Though the devices have advanced features and functions, they should easy to use.

An intuitive menu control and buttons on the device will be convenient for homeowners and professionals.

As an inspector, look for the large screen camera to know the exact condition without guessing.


A thermal camera unit for service providers needs to wear and tear-resistant and withstand rough handling. If you are purchasing it for your home to use once in a while, save money and buy inexpensive basic thermal leak detectors.


A high-quality thermal sensor is essential to get a clear and accurate temperature reading in any application. For this, you have to choose the thermal camera with high thermal sensitivity so you won’t miss any defects which may cause energy loss in the future.

Additional Features

If you want the moisture content data, a moisture pen is essential. Most of the thermal camera for leak detection has included this pen in their unit.

A thermal camera with a laser pointer shows where you exactly pointing the camera. It is important while you looking for hidden pipes.

Apart from room temperature, another important data to know is humidity. A thermal camera unit with a humidity sensor can inform you if the humidity is normal or higher. This is also considered as evidence of moisture in the roof or wall.

Thermal imaging cameras for leak detection are available in every price range so if you are a homeowner or service provider you will never have to worry about finding the leaks in hidden places.

Thermal leak detection saves not only the energy sources but also the money a homeowner has to spend for breakage due to hidden water or air leaks.
