Find Out Where the Moisture Is Coming From
Penetrating damp generally occurs when moisture enters a property through part of the building fabric. Unlike rising damp, it is not necessarily confined to the lower sections of walls.
Damp patches may appear on external-facing walls, around windows, on ceilings or in other areas where water is able to enter the property.
Possible causes can include defective pointing, damaged render, roofing problems, leaking gutters or downpipes, cracks, defective seals and other external building defects.
An onsite inspection allows the affected areas and relevant parts of the property to be assessed before deciding what remedial work may be appropriate.
- Damp patches on external-facing walls
- Damp becoming worse after rainfall
- Wet patches on walls or ceilings
- Peeling or bubbling paint
- Damaged plaster
- Moisture around windows or doors
- Persistent musty smells
- Recurring localised damp patches

What Can Cause Penetrating Damp?
Penetrating damp can have a number of possible causes. Identifying the route by which moisture is entering the property is an important part of deciding what work may be required.
Defective Pointing
Deteriorated or missing mortar joints can leave external masonry more exposed to wind-driven rain and moisture penetration.
Damaged Render
Cracked, loose or defective render can sometimes allow rainwater to reach the wall structure behind it.
Roofing Defects
Damaged roof coverings, flashing or other roof defects can allow water to enter and appear as damp on ceilings or upper walls.
Gutters & Downpipes
Leaking, overflowing or defective rainwater goods can repeatedly wet external walls and contribute to localised moisture problems.
Windows & Openings
Defective seals, cracks or detailing around windows and doors can sometimes provide a route for rainwater to enter.
External Wall Defects
Cracks, damaged masonry and other defects in external walls may allow moisture to penetrate during periods of wet weather.
Proceed With the Work? Your £120 Is Credited
Your £120 payment covers the penetrating damp inspection service. Following the inspection, the appointed contractor can provide a separate quotation if remedial work is recommended.
There is no obligation to proceed with that quotation.
What May Be Recommended After the Inspection?
The appropriate solution depends on where the moisture is entering the property. The source should be investigated before deciding on the appropriate remedial work.
Pointing Repairs
Where defective mortar joints are contributing to water ingress, repair or repointing may be recommended.
Render Repairs
Damaged or cracked render may require localised repair or other appropriate remedial work.
Rainwater Goods
Leaking or overflowing gutters and downpipes may need to be repaired where they are repeatedly wetting the building.
Roof Repairs
Where moisture is associated with a roofing defect, appropriate roof or flashing repairs may be required.
External Wall Repairs
Cracks, damaged masonry or other defects may require repair where they are allowing moisture to penetrate the building envelope.
Internal Repairs
Once the source of moisture has been addressed, damaged internal plaster or decorative finishes may also require appropriate repair.
