A cracked pipe inside a wall is one of the most difficult problems to detect in time. Often, the damage starts slowly, without any obvious signs, and only becomes visible when there is water infiltration, mold, or even structural damage. The sooner you identify the problem, the lower the repair cost and the lower the risk of destroying walls, floors, or furniture.
This guide explains all the signs you should look out for, the most common causes, diagnostic methods, and how to confirm whether there really is an internal leak in your home. Finally, we explain when you should call a professional and why specialized service from Canalizador de Lisboa is the safest and most effective solution.
Signs that there is a cracked pipe inside the wall
Although the pipe is hidden, water almost always leaves clues. Here are the most common signs:
1. Moisture stains on the wall
This is the most common symptom. The spots may start small and grow over several weeks. They usually appear as dark, brownish areas or areas with a different texture.
2. Peeling paint or blisters on the wall
When water seeps behind the paint, it forms bubbles and causes the paint to peel off easily by hand.
3. Smell of mold or mildew
Moisture trapped in the wall creates an ideal environment for mold. Even if you don't see any stains, a persistent smell may indicate a hidden leak.
4. Sudden increase in water bill
If you haven't changed your consumption habits but your bill has increased, there may be a continuous leak inside the wall. Checking the meter when all the taps are closed is a great test.
5. Sounds of running water
If you hear a constant dripping or running sound behind the wall without any faucets open, it is a clear sign of a leak.
6. Unexplained warm floors (in houses with hot water pipes)
A cracked hot water pipe can heat up areas of the floor, especially in homes with built-in installations.
Common causes of cracks in pipes
A pipe does not crack by chance. Here are the most common reasons:
- Natural aging of the piping
- High water pressure
- Sudden changes in temperature
- Poor material or incorrectly installed pipes
- Internal obstructions that put too much pressure on the pipe
- Constant vibrations, banging, or construction work nearby
- Corrosion in old iron or copper pipes
If you have an old building, or if the plumbing was installed using inexpensive materials, the risk of cracks is greater.
How to check if there is a cracked pipe inside the wall
Some tests can be performed by the owner, but others require professional tools.
1. Water meter test
Close all taps, turn off appliances, and check the meter. If it continues to move, it means there is a leak somewhere in the installation.
2. Visual and tactile inspection
Run your hand over the surface of the suspicious wall. Even a slight feeling of cold or dampness may indicate infiltration.
3. Monitoring the evolution of spots
If the stain grows daily, there is a high probability of active leakage.
4. Thermal cameras (professional diagnosis)
Professionals use thermal cameras to identify temperature differences caused by accumulated water. It is an accurate way to locate the exact point of the crack.
5. Acoustic equipment
There are devices that detect the sound of water escaping and allow leaks to be located without breaking walls.
6. Wall endoscopy
A small hole allows a microcamera to be inserted to directly view the inside of the wall.

What are the risks of ignoring a cracked pipe?
A cracked pipe never fixes itself. The more time passes, the more damage it can cause:
- Structural damage to walls or floors
- Molds harmful to health
- Persistent unpleasant odors
- Much higher water bills
- Short circuits if water reaches electrical cables
- Possible need for major works in the future
The sooner you resolve it, the less impact it will have and the cheaper the repair will be.
When should you call a professional?
If you have more than one of the signs mentioned, or if the spot grows rapidly, it is essential to seek specialized help. The earlier the diagnosis is made, the fewer walls need to be opened and the lower the total cost will be.
