Rising damp occurs when groundwater travels upward
through brick and plaster due to capillary action.
Over time, this moisture causes:
-
Peeling paint
-
Bubbling plaster
-
Musty odours
-
Mould growth
-
Structural damage
Our ventilation-based system helps regulate and reduce
internal wall moisture without invasive chemical injection.

FAQ
Does rising damp go away?
No. Rising damp does not resolve without intervention.
Moisture continuously travels upward through masonry from the ground, meaning the problem will persist — and often worsen — over time. Without treatment, it can lead to ongoing plaster damage, mould growth, and potential structural deterioration.
At Cornerstone Damp Systems, we focus on solutions that help regulate and reduce internal wall moisture effectively.

How long does installation take?
Most installations are completed within 1 day, depending on the size of the affected area.
Larger properties or multiple rooms may require additional time, but disruption is kept to a minimum. We work efficiently and ensure all areas are left clean and tidy after completion.
-
Is drilling damaging?
No — when done professionally, drilling is safe and controlled.
We use precision tools and follow a structured installation method to ensure:
-
Minimal surface disruption
-
No impact on structural integrity
-
Clean, neatly finished installation points
-
All work is carried out with care and attention to detail.
-
How long before results show?
Initial improvement can begin within a few weeks, but full results depend on:
-
Severity of the damp
-
Wall thickness
-
Environmental conditions
Walls need time to naturally dry out once moisture levels are regulated. In most cases, noticeable improvement occurs over 1–3 months.
