“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

What is Rising Damp Treatment?
Rising damp is the upward movement of ground moisture through the porous materials in your walls. It occurs when a damp proof course (DPC) is missing, has failed, or has been bridged. Rising damp typically affects the lower metre of internal walls, damaging plaster and decorations and creating the damp conditions mould needs to grow. Left untreated it can lead to timber decay and structural problems. Our ISSE-accredited surveyors diagnose the true cause before recommending treatment — rising damp is far rarer than many homeowners are told, so accurate diagnosis matters.
The warning signs to look for
Catching the problem early keeps repairs simpler and less costly. If you notice any of these signs, it is worth booking a specialist survey before the damage spreads.
Book a complimentary survey
- Damp patches on lower walls, usually up to around one metre in height
- A distinct tide mark or staining line across the wall
- White, fluffy salt deposits (efflorescence) on brickwork or plaster
- Peeling or bubbling wallpaper and flaking paint
- Crumbling, blown or hollow-sounding plaster
- A persistent musty smell in ground-floor rooms
- Decaying or rotting skirting boards and timber near the floor
Our treatment process
Every job follows the same careful, diagnosis-first method — so you know exactly what is happening and why at each stage.
Detailed survey using calibrated moisture-testing equipment to confirm rising damp and rule out other causes
Drilling injection holes at measured intervals along the mortar bed at the damp proof course line
Injecting chemical DPC cream under controlled pressure to form a continuous water-repellent barrier
Removing salt-contaminated plaster and applying our specialist Proofterior Dry System re-plastering
Final moisture checks and issue of your 25-year insured guarantee certificate

Everything you might be wondering
Most rising damp treatments are completed within 2-4 days, depending on the area affected. The specialist plaster then needs around 4-6 weeks to fully dry before you redecorate.
Yes. Once the new specialist plaster has dried we leave the walls sound and ready for decoration. We will advise you on the right time and the correct breathable finishes to use.
Not always. Condensation and penetrating damp are frequently misdiagnosed as rising damp. Our diagnosis-first survey confirms the real cause so you only pay for the treatment you genuinely need.
