Internal Damp Wall Treatment
Internal dampness is usually a symptom of a problem elsewhere in the structure — we find the source before treating the wall.
Typical Symptoms
How this usually shows up
- Bubbling or flaking interior paint
- Visible mould growth
- Skirting board damage or swelling
- Persistent musty odour in a room
Common Causes
What's usually behind it
- Rising damp from ground moisture
- Penetrating damp from an external wall issue
- Condensation from poor ventilation
- Leaking pipework within the wall
Treatments We Apply
The right treatment depends on substrate, severity, and exposure — determined during assessment.
Crystalline Waterproofing
Cementitious Waterproofing
PU Injection Grouting
Our Process
We test moisture levels and pattern to distinguish rising damp, penetrating damp and condensation, then apply a negative-side barrier or source fix rather than just repainting over the symptom.
