Key Take Aways
Penetrating damp occurs when water moves horizontally into walls through structural issues like crumbling mortar or failed damp proof courses—common in older or London properties.
Symptoms include a musty smell, damp walls, reduced heat retention, and sometimes visible mould and plaster damage.
All Weather Coating’s solution: their microporous weatherproof coatings protect brickwork by sealing cracks yet allow walls to breathe; can be applied year-round and offer noticeable improvement in dryness almost immediately.
Comprehensive treatment not only coats walls but follows a full survey → crack/defect repair → cleaning → coating routine for long‑term protection.
Energy efficiency benefits: once walls are dry, they trap heat better, helping reduce heating costs and improving indoor comfort.
Durability & guarantee: coatings come with long-term warranties, comparable to typical 20–25 year guarantees offered by similar providers.
Penetrating damp is a common problem in buildings but it’s not one that should be ignored and once caught the problem should be solved as soon as possible to prevent any future or further issues.
What causes penetrating damp?
The cause of penetrating damp is simply down to water and moisture from outside penetrating through the walls causing the dampening damage inside.
It’s not just the ground floor penetrating damp can effect, it can be a problem for a property on any level whether on the first floor of a house or 12th floor of a flat. Although damp can affect all levels you should be aware of the fact that it is known to be more prevalent higher up.
The most common causes for penetrating damp include:
- Porous Walls
- Spalled Bricks
- Degraded Mortar
- Building Defects
All of the above are reasons why penetrating damp can affect your property so it’s always a good idea to ensure your home isn’t being affected by any of these defects.
