External repairs

Addressing the external causes of penetrating damp is essential. This includes: repairing damaged brickwork; repointing, repairing or replacing damaged gutters and downpipes; and ensuring the integrity of the roofing. These repairs prevent further water ingress and protect your property from future damage.

Waterproof coating

Applying waterproof coatings and sealants to external walls can provide an additional layer of protection against penetrating damp. These products create a barrier that prevents water from entering the property, but also allows trapped moisture to leave. We use only the highest-quality products.

Cavity wall

In some cases, saturated cavity wall insulation can contribute to penetrating damp. We conduct thorough checks to identify and address any issues with cavity wall insulation, ensuring it remains dry and effective.

Where internal walls have been affected by penetrating damp, we provide internal damp proofing treatments, including specialist plastering and membrane systems. These treatments ensure that the internal walls are dry and protected.


Our process for addressing penetrating damp is thorough and systematic, ensuring every aspect of the problem is addressed effectively. We follow a structured approach to deliver reliable and lasting solutions.

Our experienced surveyors conduct a detailed inspection of your property both externally and internally to identify the source and extent of penetrating damp. We use diagnostic tools and techniques to ensure accurate diagnosis.

Below are some of the most commonly asked questions regarding penetrating damp.

Damp in general can cause respiratory health problems, especially amongst elderly people and children or people with asthma. Dangerous is a bit of a strong word but, depending on a person’s health, it might not be healthy for an individual.

Penetrating damp is water ingress that has managed to penetrate through the building structure. Look out for wind-driven rain entering masonry, a leaky roof, burst water pipes, broken gutters with water running down walls or perhaps defective plumbing. Condensation, on the other hand, is typically caused by the build-up of excess atmospheric moisture within the property condensing on cold surfaces, when there is inadequate ventilation to remove it.

Water ingress is a term used to describe water entering property through the masonry or roof covering and may be due to a building defect such as a blocked gutter, leaky roof, failed damp proof course, wind-driven rain or deterioration of mortar within the brickwork joints. Water ingress can also be caused by faulty plumbing.

First, identify the source of moisture. Find where the water is coming from and how it is getting into the property. Then repair the defect to stop further moisture from entering the property. Finally, consider what repair works need done on the affected area.

The DIY part of a penetrating damp problem is establishing the cause of water ingress, which will either be due to a building or plumbing defect. This could be driving rain or a leaky roof which may be due to some missing slates. Perhaps the washing machine or dishwasher is letting out water. Check the pipes behind these units to make sure they are fitted correctly. After using some DIY to stop the water ingress, you will need to call the professionals to establish the damage penetrating damp has caused to the property’s timber.

If cavity wall insulation is correctly specified and installed to the correct density, it will not absorb moisture. But if it is incorrectly blown, moisture can bridge the gap between the outside wall and the inside masonry leaf.

You will need to arrange for remedial works to the chimney before the water ingress starts causing other problems. Once you have stopped the penetrating damp issue within the chimney, you can then look to resolve any damp issues inside that have occurred as a consequence of the chimney issue.

Yes, it can do. If the damp surface cools to dew point, condensation will form and this may allow mould spores to germinate. But the salts in building materials can prevent growth.

It can be serious as, besides its usual symptoms, it can also encourage wet rot. This wood-destroying fungus can seriously damage the timber structure at the source of moisture. 

The initial source of the water ingress may be covered as an ‘act of god’ or storm damage; however, penetrating damp is considered a wear-and-tear issue, which means most insurance companies would not cover the issue. Our best advice is that, if you are concerned, you should check with your insurance provider for clarification.
