How to diagnose damp in your home

Diagnosing damp in your home

With the intermittently wet and windy weather the UK experiences, it is no surprise that, occasionally, our homes succumb to conditions and come down with a case of damp. Damp can manifest itself in any number of different ways but condensation, rising damp and penetrating damp are three of the most pervasive.

We have years of experience in penetrating damp treatment and our team is acutely aware of the issues it can cause.

In this post, you’ll learn not only how to identify damp but how to treat it.


Most prevalent of all of the iterations of damp, this is perhaps the case because condensation is the result of excess moisture forming within the home, rather than forcing its way in from the outside.

Everyday tasks – cooking, washing and drying clothes indoors – are all contributors to condensation, which of course, means that moisture is almost always present in the air. When it becomes a problem though, condensation announces itself by forming water droplets on the windows and walls of your home. Over time, it can decay window frames, damage paint, and plaster, and in the very worst cases, produces black mould capable of causing respiratory issues – all best avoided.

Rising damp

The older a house is, the more likely it is to be affected by rising damp. Preventing damp in old houses is trickier because damp proof courses and damp proof membranes, the natural counteragents, did not become a requirement of building regulations (in their most primitive form) until 1875. Problems with rising damp stem from a missing or worn damp proof course, one that sits below the ground surrounding your home, or simply an absence of quality drainage. 

The symptoms of rising damp are similar to that of any other damp problem: peeling paint and wallpaper and damaged skirting boards and plaster. In one respect though, rising damp is able to distinguish itself from its counterparts: by tattooing walls with a white, powder-like substance. In its advance, rising damp picks up salts from the ground and building materials, which is why it leaves behind white-tinged tide marks on the walls of your home. 

Penetrating Damp

Moving horizontally rather than vertically, penetrating damp infiltrates a home through its walls. Some kind of defect in your home can be held accountable for its advance. Whether that is faulty brickwork or guttering, cracked render or internal leaks, the culprits can be many in number. Penetrating damp makes itself known to homeowners with dampness on walls. These areas of dampness will worsen in parallel with the increasingly severe weather.

How to treat damp

Damp is only ever a consequence of some fatal flaw in your home’s make-up. Rectify the flaw and you also rid your home of damp. As debilitating as damp problems may seem, they can easily be cured with the right help on hand.

Penetrating Damp Treatment London

In 2013, Aviva, the UK’s biggest home insurer compiled a list of the most common claims made against home insurance policies. Topping the list was ‘escaping water’. Another insurance provider in 2013, Confused, also listed ‘escape of water’ within its top five most common claims.

For homeowners throughout the UK then, damp is an extremely prevalent issue. Unfortunately, it is also one of those issues that doesn’t seem to be visible until it is too late. Uncovering the source of the issue can be extremely tricky and you can paper over one gap only to find another has developed elsewhere.

To walk you through some of the ways damp is able to infiltrate your home as well as the best ways to ensure it never returns, we have put together this overview of why and how we carry out damp proofing. We are accomplished damp specialists in London and we are intent on helping all of our prospective customers rid their homes of damp problems indefinitely.

Dealing with damp: Condensation

Washing, cooking, cleaning and drying clothes are all everyday tasks that contribute to the levels of moisture within the home. When the same home is poorly ventilated, this excess moisture has no escape route, which forces it, eventually, to condense and linger on windows and walls.

If you can confirm that the damp walls within your home are merely the result of condensation, you only need to better ventilate your home to alleviate the issue. Opening windows at more regular intervals, avoiding drying clothes indoors and investing in an extractor fan or a dehumidifier will rid your home of damp.

Dealing with damp: Penetrating damp and rising damp

On the other hand, if damp is present in your house because of penetrating or rising damp, you have an altogether different animal on your hands. Rising damp is different from penetrating damp in that it travels upwards through a floor or wall while penetrating damp infiltrates horizontally. In terms of treating the two however, they can more or less be dealt with as a collective.
