Penetrating Damp treatment
What is Penetrating Damp? A Detailed Explanation
Penetrating damp (also known as "water ingress") is moisture that penetrates through walls and façades from the outside. This problem occurs when rainwater, groundwater, or moisture from the environment finds its way through building materials. Unlike rising damp, penetrating damp can occur at any height in a wall—even on upper floors.
How to Identify Penetrating Damp Treatment
- Damp patches that worsen after rainfall
- Mould growth on internal walls
- Peeling paint or wallpaper
- Efflorescence (white, powdery deposits)
- A cold, damp-feeling wall
- Possible visible water damage around windows, eaves, or cracks
The Crucial Difference: Penetrating Damp Treatment vs. Rising Damp
Many homeowners confuse these two types of damp problems, but they have different causes and require different solutions:
Penetrating Damp:
- Source: External (rain, groundwater, leaks)
- Movement: Horizontal or from top to bottom
- Location: Can occur anywhere, often on façades, roofs, or around openings
- Seasonal Pattern: Typically worsens during wet periods
- Visible Signs: Localised damp patches that correspond with external issues
Rising Damp:
- Source: Ground moisture that "creeps" upwards
- Movement: Vertically upward from the foundation
- Location: Always starts from the floor or lower part of walls
- Seasonal Pattern: Constantly present, less weather-dependent
- Visible Signs: Dampness limited to the lower 1-1.5 metres of walls
These fundamental differences are crucial for correct diagnosis and effective treatment.
Causes of Penetrating Damp
Penetrating damp can be caused by:
- Damaged roof tiles or gutters: Leaks that allow water to flow down façades
- Cracks in façades: Frost damage, subsidence, or poor maintenance
- Faulty sealant joints: Around windows, doors, and wall connections
- Porous building materials: Brick or mortar that becomes saturated
- Poor ventilation: Condensation exacerbated by existing moisture
- Splash-up: Groundwater splashing against lower walls during heavy rain
Consequences of Untreated Penetrating Damp
Long-term penetrating damp leads to:
- Structural damage to walls and woodwork
- Health risks from mould growth and dust mites
- Higher energy bills due to reduced insulation value
- Deterioration of interiors and belongings
- Decreased property value

Conclusion: Act Now to Protect Your Home
Penetrating damp and rising damp are fundamentally different problems, each requiring their own approach. While rising damp exhibits an upward movement from the foundation, penetrating damp manifests as water ingress from the outside. Correct identification by a professional is the essential first step towards a permanent and cost-effective solution.
