Rising Damp

What is Rising Damp?

Rising damp is a form of moisture that travels upwards through walls from the ground. It occurs when groundwater moves through porous building materials like brick, stone, or mortar via capillary action. If left untreated, rising damp can lead to unsightly staining, crumbling plaster, and even structural damage.

It’s often confused with other types of damp, such as condensation or penetrating damp, so correct diagnosis is essential.

Signs of Rising Damp

Common signs that may indicate rising damp include:

• Tide marks or damp patches on lower walls (up to 1m high)

• Peeling paint or wallpaper

• White, powdery salt deposits on walls

• Rotting skirting boards or timber

• Musty smells near affected areas

If you’re noticing any of these symptoms, it’s important to have a professional assessment to determine the exact cause and avoid unnecessary treatments.

How We Diagnose Rising Damp

As independent surveyors, we provide unbiased, expert assessments with no sales agenda. Our rising damp inspections may include:

• Moisture meter readings along affected walls

• Salts analysis testing to confirm the presence of hygroscopic salts

• Thermal imaging to detect damp patterns

• Invasive testing, such as calcium carbide tests, where necessary

We’ll always explain our findings clearly and help you understand whether it’s truly rising damp — or something else entirely.
