How do you determine cause of damp?

Once you've identified the damp, it's cause can usually be narrowed down to one of four main causes:

1. Leaking pipe. If a pipe is leaking somewhere in the home, this can be causing the damp to spread.
2. Ventilation. Poor ventilation can trap moisture – typically from baths, showers, boilers etc.
3. Rising damp.
4. Penetrating damp.

Likewise, how do you find out what is causing damp?

In this instance to find the cause of the penetrating dampness you will need to check your walls for cracks in mortar, your cavity for debris in the wall and any rusty or dirty wall ties, your roof for broken tiles and flashing and your guttering for splits, cracks and leaking joints.

Also, how do you check for damp in walls? To test for moisture inside the walls, start with manual tests and proceed to moisture meters.

1. Look at the wall surface carefully.
2. Push on the wall slightly to see how it feels.
3. Smell the wall to test for moisture.
4. Drill two small holes, about 3/16 inch in diameter and about 1 inch apart, into the wall.
