What are the causes of damp?

In our last article we looked at the affects of damp, where we discussed the three main ‘types:

These are caused by differing environmental factors that change the condition of your homes structure. Some older houses are often very well ventilated; though once you begin to insulate them it can create issues leading to condensation.

At RTM services we focus on providing damp proofing in the London area. As a London damp proof company with years of experience, we pride ourselves on being damp proofing specialists. Over the past few years, we have noticed rising levels of ground water throughout the London area due to changing weather conditions. Unfortunately, this can lead to your current damp proofing becoming overwhelmed and begin to struggle to handle events of unusually heavy rainfall. This can then contribute towards penetrating and rising damp.

Damp problem: how do I know if I’ve got one? 

Damp won’t always be visible to the naked eye. Condensation problems are easy to spot as you may notice your window becoming misted up, or a droplet of water on your wall, even though your windows may be closed. If you’ve noticed these signs before, it is a strong sign that you could have damp. A London based damp and condensation specialist will source the root of the problem and then be able to offer advice on managing your condensation.

Other signs that will help you to spot the different kinds of damp include blistering plaster or peeling wallpaper. If you’ve noticed a constant musty smell or you’ve found patches of black mould, this can also be a sign of damp. Damaged skirting boards and tidemarks on your wall can often be a sign of rising damp. If this is the case in your home, a rising damp specialist can carry out a damp survey, which will show the cause and size of your problem.

What is ‘damp proofing’ and why is it so important?

Damp is often absorbed through the walls or the floors of a property, going through to the interior. Damp proofing is the general term given to the methods and treatments that are used to prevent this. It involves using materials to form part of your property’s structure to keep any moisture out.

By using damp proof membrane or a damp proof course, the spreading of moisture through walls can be prevented by capillary action. Another way of achieving damp proofing is the use of cavity walls. This is whereby an air gap separates the interior and exterior walls. The actual cavity also prevents condensation. The outer wall then acts as a barrier to stop rainwater getting in.

As we’ve discussed before, damp proofing is vital because damp in your home can lead to health risks, compromise structural integrity and even lower the value of your house. Damp environments allow black mould to grow, but its spores can directly affect your lungs whilst also increasing your chances of catching colds and flu.

Does my home already have damp proofing?

Your house will generally contain some element of damp proofing if it was built after 1870. This could range from a damp proof course, damp proof membrane or cavity walls. As damp proof specialists in London, we often find that properties in South London, mostly well built Edwardian and Victorian houses, already have several layers of slate. With this being said, those houses constructed during the Georgian era and onwards have less durable damp proofing. This is due to several boom periods where house developers used bitumen-impregnated hessian – a less efficient and less durable form of damp proofing.

At the time in which they were installed, most damp proofing techniques were adequate. But over time, cavity walls can fill up due to debris that comes from mortar, bitumen and hessian that had degraded. This causes the damp proof to be less effective. Unfortunately, this will eventually decay and can cause slate to crack due to the constant pressure applied by the contracting of the underlying clay.

With all of this being said, your home may require a damp proofing upgrade if it was built before the 20th century.

I can smell damp in my home: what can I do to get rid of it?

Masking the smell is only a temporary fix and won’t free your house from damp. We recommend identifying the source of the damp. You can do this yourself by looking for leaks, which may include your walls being penetrated by heavy rain, or perhaps an overflowing guttering. You may need to call a specialist to find whether you have any leaky pipes, as some may not be detectable by eye.

Condensation is also a very common problem in houses across the UK. It becomes worse particularly throughout winter when the temperature drops. To reduce condensation, it is important to ensure you have sufficient ventilation, especially in areas where you cook, shower or tumble dry clothes, as these all create moisture.
