Ceiling Leak Detection

Have you recently noticed a mark on your wall or ceiling that wasn’t there before, or is there water dripping through from above? This may indicate a hidden leak, but these water leaks are not always coming from directly overhead.

We get many enquiries from customers who have called out a plumber for a leaking ceiling. The plumber investigates, normally through destructive techniques, is unable to find the source of the leak, and leaves scratching their head. Therefore the client is no further forward, and also out of pocket from the call out charge. Professional leak detection means getting to the cause of your problem quickly and cost effectively, with the minimum disruption to your life and property.

There are many possible causes of a leak from ceiling, including central heating leaks, waste pipe leaks, bathroom leaks and even rain water getting in. The dripping water can then track along beams and pipes until it reaches its lowest point and you see the mark on the ceiling below.

Ceiling Leaking: Top Tip

TOP TIP:  If you are able to draw a pencil line around the edge of the stain, then this will help you see if the problem is getting worse or not.  Keeping a diary of when the leak happens may help you work out if it is rain water getting in after bad weather, or maybe it happens every time your teenager has been having a 2 hour shower!

Common Signs of Ceiling Water Damage

Water Spots

Water spots are one of the most conspicuous signs of water damage to a ceiling. Water spots generally appear as discoloured patches of paint on the ceiling, which may have darker edges or ‘halos’. It is important to note that the presence of water spots alone indicates the presence of water damage, but may not necessarily imply a current leak. Therefore, further investigation is always advised to determine the source of the original water damage and any present ceiling leaks. If you suspect a current leak and/or water spots on your ceiling, it is essential to contact a professional immediately to assess the situation and mitigate any further water leak damage.

Peeling Paint

One of the most common signs of ceiling water damage is peeling ceiling paint. Paint that appears to be bubbling or showing signs of water spots is an indication that water may have been leaking from the ceiling. In order to determine if the peeling paint is indicative of water damage, it is important to feel the surface of the paint. If it is damp, this may suggest that there is a leak in the ceiling that is causing the damage over time. Professional help should be sought in order to locate and remediate the source of the ceiling water damage. If left unattended, this type of damage can cause significant damage to the integrity of your ceiling, and therefore it is important to take swift action.

Mildew can also be an indication of ceiling water damage. It can take the form of a white, grey, or even black powdery substance that grows anywhere there is a high level of dampness. Areas of the home that are affected by water leaks and condensation are especially prone to developing mildew. If any areas of your ceiling appears to have a coating of mildew, then this is a sign that there is a source of moisture present and the problem needs to be addressed quickly. You may also be able to spot patches of mildew on fabrics, wallpaper or other surfaces in the home. It is important to clean mildew off surfaces as soon as possible to prevent any further damage.


Another of the frequent indications of ceiling water damage is discolouration, which may appear in the form of dark spots or yellow stains. Discolouration usually occurs as a result of water seeping through the roof and accumulating on the surface of the ceiling. In some cases, the discolouration may be due to mould or mildew growth associated with the presence of excess moisture. If you notice discolouration on your ceiling, it is best to take action and address the underlying cause, such as a roof leak, to prevent further damage.


Where is My Ceiling Leak Coming From?

Consider Water Sources

When it comes to establishing the origin of a ceiling leak, it’s important to consider the water sources. It may seem obvious, but the source of the water could be something as simple as a leaking shower, a broken pipe, a leaky roof, or a blocked gutter. Additionally, if a recurrent issue is present, consider any recent changes to the building’s plumbing infrastructure that may have caused the leak, such as new fixtures or construction. By routinely checking and addressing potential water sources, you can prevent future ceiling leaks from occurring.

Checking Plumbing and Appliances

For those looking to establish the origin of a ceiling leak, it can be helpful to check plumbing and appliances in the building. Checking the water delivery pipes for potential leakage, especially if they run through the ceiling, is often a fruitful exercise. Additionally, it’s worth inspecting appliances such as washing machines, dishwashers, showers etc for potential breakages or loose seals. Understanding where issues may be arising can be instrumental in pinpointing the source of the ceiling leak.

Examining Outside Sources

It is important to examine reviewing outside sources when establishing the origin of the ceiling leak. Professional help may be required to determine what may have caused the leak and trace it back to its source. Engaging the services of someone familiar with building construction and researching other houses in the area is a recommended step to take. While conducting the search, checking local weather records to determine if any known inclement weather in the area could have been responsible for the leak should be taken into consideration. Additionally, a check of any maintenance or repairs that may have been done to the roof or eaves of the building should be taken into account. All of these steps can help throughout the process of establishing the source of the ceiling leak.

Ceiling Leak Detection Equipment

The Leak Team can attend your property and track down the cause of your ceiling leak.  Using our specialist equipment and expertise we can trace the leaking water back to its source.   We can use endoscope cameras to see hard to reach places and thermal imaging to discover the extent of the wet area.  We can check the integrity of your drainage system to see if your waste pipes are leaking and pressure test the pipes to your taps to rule out a water leak on fittings and connections.  We may even replicate heavy rainfall to check if that is what is causing the staining on your wall or ceiling.

Fixing a Ceiling Leak

Once we have traced the origin of you leak from upstairs, then we can make recommendations on the best way to fix the leak and stop the problem from happening again. Our service includes a photographic survey report with detailed information to help whoever comes after us to carry out the repair work needed. You can also send this report to your insurers if you have Trace & Access cover on your buildings insurance which may reimburse you our fee along with the cost of the ceiling repair.
