What is Rising Damp?
What is rising damp? That is a common question asked by customers at Timberwise. Rising damp is a term for the movement of water from the ground rising up through the outer walls of the building by capillary action.
A simple description is that the water will rise up the wall just like the way water soaked up by a sponge. This water will contain salts which is deposited onto the wall. Other building materials that are near to the affected wall, such as skirting boards, joists and plasterwork will absorb the moisture from the ground. This can result in problems such as wet rot.
It is a particular problem in older buildings where the damp proof course (DPC) has become damaged or when the ground level around the house has been raised by the addition of a path or driveway.
Dampness in the house isn’t necessarily caused by rising damp as there may be another source of water that you are unaware of causing the problem. This is why it is important to contact a fully qualified surveyor so a full rising damp inspection and treatment can be carried out.

Treating Rising Damp
Any form of rising damp must be stopped at the source to be sure that the damp problem is fully rectified. Carrying our quick fixes will only cover up the issue for a short term period and therefore make it more expensive for you to solve in the long term.
One solution for treating rising damp at your property is the installation of a damp proof course. For a professional rising damp treatment service, Timberwise will provide an experienced surveyor who will visit your property and outline potential damp proofing treatments and costs.
Rising Damp Treatment Methods
Below are the methods that are used to treat rising damp from your property:
- Rising Damp Survey- Treating rising damp should be carried out by a specialist surveyor. Having a surveyor who has the experience and knowledge of damp will inspect the property for all damp issues and provide the best rising damp treatments for your property.
- DryTek Damp Proofing Injection Cream- The DryTek Damp Proofing System is a unique product to Timberwise, this damp proof injection cream is applied into old brick and stonework structures and into granite boulder walls. This creates a barrier that moisture cannot pass, the cream will tend to fill any fine cracks and this forms a solid plug. This product comes complete with a 20 year guarantee giving complete peace of mind.
- Damp Proof Course- Most modern properties are often built with a damp proof course installed, usually in the form of an impermeable plastic membrane, which is placed along a mortar line near the ground. Older properties, however, are often built with no damp-proof course, or the original course has failed over the duration. If your property is in need of a damp proof course there are a number of methods that our team of qualified technicians can implement. We provide a variety of damp proofing systems to suit different property requirements, for example; a property constructed with stone may require an electro-osmosis system, whereas a property with brickwork construction may require a pressure injection.
- Injection Mortar- This grouting type of material is ideal for many applications, particularly where a good sized bedjoint is in evidence. The damp proofing agent is carried into the porous mortar beds and rubble by the rising damp, where it crystallises to form an impermeable barrier to control subsequent water rise.
- Timberwise EOS (Electro Osmosis System)- The Electro-Osmosis System introduces a very small electric current into the wall just above the ground level. The current repels rising moisture back down the wall. As long as the charge is maintained the walls will remain dry and free of damp.

What is the Cost Of Rising Damp Treatment?
“How much does rising damp cost to treat?” It is perhaps one of the most frequently asked questions by homeowners with a damp issue. The cost of damp proofing is subjective to a number of variables including; property size, location and accessibility.
The type of damp proofing system to be installed also has an effect on cost. Physically replacing the injected damp proof course is a very difficult process that would definitely involve large amounts of structural work taking place – for that reason, the most common and cost effective treatment for rising damp is to install what is known as a chemical damp proof course (See our DryTek Damp Proofing System above) or dependent on the situation an electro osmotic damp proofing system.
What Happens If Rising Damp Is Left Untreated?
If rising damp is left untreated then it can lead to serious issues with the structural integrity of your property. If you left, the rising damp problem will worsen and the cost of damp proofing will only continue to rise.
Any decoration that you have added to your home, such as wallpapering and plastering, will deteriorate increasing the costs further. If you are in the process of selling your home a damp issue makes the process longer for you and delay a sale.
Can Rising Damp Cause Health Issues?
This question is one that is asked by many customers. In many cases if treated in good time then damp won’t be a concern for your health.
If left unchecked it can lead to other issues forming, such as mould, that can have implications on health. Having a damp smell in your property isn’t pleasing and the health risks aren’t a real issue.
How to Prevent Rising Damp?
Most of the modern buildings in the UK have a damp proof course which can act as a barrier water penetration. However, there are some cases where there is damage that affects the building and damp can become a problem. All the external masonry, guttering and rainwater pipes should be properly maintained.
There should be regular checks for signs of dampness on internal surfaces on the ground floor surfaces and skirting boards.
Checks should also be made on ensuring that external roofs, gutters and roof pipes should be free from debris as much as possible. All air vents must be free from obstruction to allow air to flow freely out of the building.
