What Is Rising Damp?
Rising damp occurs when groundwater travels upwards through porous building materials, such as brick, mortar, or stone. This happens when the damp proof course (DPC) – a waterproof barrier installed during construction – becomes damaged, bridged, or missing altogether.
As moisture rises through the wall, it carries dissolved salts that can contaminate plaster and leave unsightly marks or blistering paint.
Common causes include:
- A missing or defective DPC
- Raised ground levels outside bridging the DPC
- Blocked cavities or external render that traps moisture
- Leaking downpipes, gutters, or poor drainage contributing to ground moisture
Typical signs of rising damp:
- Dark tide marks up to one metre above floor level
- Peeling wallpaper or blistering paint
- Soft, crumbling, or powdery plaster
- White salt deposits (efflorescence)
- Damp, musty odours near skirting boards
Spotting these early can help prevent structural decay, timber rot, and potential health risks from mould growth.
Our Rising Damp Treatment Process
At London Damp Solutions, every rising damp case begins with an in-depth property survey carried out by a qualified damp specialist. Once diagnosed, we use a structured process to treat the affected area and prevent reoccurrence.
1
Damp Survey & Diagnosis
A surveyor conducts a moisture assessment using digital meters and visual inspection. You’ll receive a detailed report outlining the problem, cause, and recommended solutions.
2
Chemical Damp Proof Course (DPC) Injection
We install a high-performance chemical DPC into the affected wall base, forming a continuous barrier that stops ground moisture from rising.
3
Salt-Contaminated Plaster Removal
Existing plaster contaminated by salts is removed and replaced with a specialist renovating plaster system, designed to allow walls to dry out properly while preventing future salt migration.
4
Masonry Drying & Replastering
Once the DPC is installed, the walls begin drying over time. We ensure the masonry is fully prepared before replastering and redecorating.
5
Preventative Advice
Our specialists provide guidance on maintaining ventilation and drainage to keep the property dry long-term.
All work is in line with British Standard BS 6576 for remedial treatment of rising damp in masonry walls.

Meet Our Damp Specialist
James Nicholls started his career at just 16 as a general labourer for a damp proofing company. His drive to learn quickly saw him working alongside skilled tradesmen, where he gained hands-on experience in:
- Structural and first fix carpentry
- Woodworm and dry rot treatments
- Structural repairs and damp proofing applications
- Plastering and specialist finishes
Over the years, James built a reputation for quality workmanship and reliability. He went on to subcontract for multiple damp proofing firms, managing a small team and overseeing projects from start to finish on-site.
The Signs of Rising Damp
If you notice any of the following, it’s time to book a professional inspection:
- Damp or discoloured patches at the base of walls
- Soft or crumbling plaster
- White salt deposits (hygroscopic salts) appearing on paint or plaster
- Rotten or decaying skirting boards
- A musty smell or visible mould growth
- Timber decay near floorboards or joists
These indicators often worsen during wet seasons when groundwater levels rise. Addressing them early helps protect your home’s structure and value.
Rising Damp in Historic & Commercial Properties
Treating rising damp in heritage or commercial buildings requires specialist expertise. Traditional materials such as lime mortar or stone walls behave differently from modern brickwork and require sympathetic treatment to avoid further damage.
At London Damp Solutions, we take a heritage-sensitive approach:
- Non-invasive moisture detection methods
- Lime-compatible treatments for breathable structures
- Conservation-approved materials and finishes
- Discreet work designed to preserve your property’s aesthetic and historical integrity
For commercial properties, we ensure minimal disruption to business operations while maintaining safety and compliance standards.

Frequently Asked Questions
What is rising damp, and why does it occur?
Rising damp happens when groundwater moves up through porous building materials due to capillary action. It’s typically caused by a missing or failed damp proof course, or by external factors like high ground levels or poor drainage.
How can I tell if my property has rising damp?
Look for tide marks, blistering paint, salt deposits, or peeling wallpaper near the base of walls. A musty smell and soft plaster are also key indicators.
Is rising damp dangerous to my health?
Indirectly, yes. Damp environments can promote mould growth, which can trigger respiratory problems, allergies, and worsen asthma symptoms.
How do professionals treat rising damp?
Our treatment involves injecting a chemical DPC into the masonry to form a waterproof barrier, removing salt-contaminated plaster, and replastering with damp-resistant materials.
Do you offer guarantees on rising damp treatment?
Yes. All rising damp work carried out by London Damp Solutions includes a comprehensive written guarantee for long-term peace of mind.
