With regards to dampness in Cardiff buildings, there are basically 3 main causes:

Damp Proofing Cardiff Wales (CF1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


These three key forms of damp are explained in depth in the following paragraphs, together with recommendations for prevention and resolution, in the event you find them in your property in Cardiff.


Penetrating damp in your home can be the result of a whole host of external factors for example: cavity wall problems, broken roof tiles, cracks in brickwork and damaged guttering. Inside your Cardiff property, penetrating damp can be a result of leaking or burst pipes, overflowing basins or baths and damaged shower trays. If left to continue leaking these elements allow water to soak into woodwork and walls, which in time result in damp dark patches on walls, broken or blistering plaster and flaking or bubbling paintwork.

If you have a leaky roof and it has been neglected over a long period of time, it can cause wet rot to develop in the timbers of your roof. Whilst it does not spread into brickwork, wet rot can cause the timber in your roof to become structurally unsafe, and in the worst case scenario you could even need to replace the whole roof - very expensive! Wet rot can be recognised by black fungus appearing on your woodwork and a "spongy" feel to the rafters, coupled with an unfamiliar musty smell from the decaying timber.

The means of prevention can be pretty basic, for instance cleaning and checking your rain gutters and roof for leaks, inspecting piping for leaks and repointing dodgy brickwork. A competent damp proofer in Cardiff will check these areas to help avoid any future problems, as part of resolving your dampness issues.


Condensation Damp Cardiff UK (029)

Condensation is extremely easy to spot and a common form of damp in many buildings in Cardiff. Minute droplets of water form on colder surfaces when warm, moist air makes contact with them. In areas where high humidity is present, such as: kitchens, boiler rooms and bathrooms, it's often caused due to inadequate ventilation.

Simple strategies to stop condensation include wiping away any droplets as soon as they form and making certain that you've got enough ventilation in the major trouble spots. Redirecting humid air outside of your home in Cardiff, by installing or upgrading extractors, cooker hoods and air bricks, will help you to remedy this problem.

A damp proof survey from a professional Cardiff specialist may also find things which exacerbate the situation by sucking in damp air from outside. An effective way to adequately control condensation is to properly regulate airflow, and your local Cardiff damp proofing specialist will offer guidance and advice on how this can be achieved.

Damp Proofing Quotes in Cardiff Wales


A damp proof course or membrane has been installed as standard on houses built in the UK since 1875. If your house was built before this period it's conceivable you might not have one installed. If your house was built after this year, but you are still experiencing rising damp, it might be that your damp proof membrane has been damaged.

Although hard to distinguish, white powdery deposits forming on walls or being found on floor surfaces, crumbling or rotten skirting boards and tide marks on walls, are all giveaway clues that you might have rising damp. It is feasible that you might have a rising damp issue if you've spotted one or all of these.

Rising Damp Cardiff Wales

Solving rising damp problems can be as straightforward as checking your property's exterior walls and seeing if you can spot a damp proof course. In order to get an adequate degree of protection the damp course needs to be above ground level by a minimum of 150mm (approximately 6"). You can dig away the surrounding earth to create this space if it is currently not enough, or you could put in a higher damp proof membrane if the first option isn't feasible.

If your damp proof membrane is installed and in order and the gap from the ground is not the explanation for the problem, dampness might be coming up through your flooring and into your walls, which could be a more problematic issue.

Damp proofing technicians in Cardiff will swiftly identify and resolve rising damp problems using a number of different techniques. A damp proofing cream (such as Dryzone or Permaguard) can be carefully injected into your wall if you have an older house with no damp proof membrane, or it is damaged over a wide area. This special cream is injected with a nozzle into evenly spaced holes drilled along the wall's mortar course, and before the cream cures it turns into liquid and penetrates into the surrounding brickwork creating a barrier that is repellent to water.

If the damp proofing cream isn't sufficient, or the damage to your membrane is too extensive, a brand new damp proof course might have to be put in. Though this is obviously a pretty extreme course of action, it may be the only way to solve your damp problems effectively.

Painting with a bitumen based, waterproof latex emulsion, is yet another potential remedy for minimal areas of membrane damage. This is applied under your floor coverings, so tiles, carpeting and laminate flooring will need to be lifted prior to work being done. In cellars this is an especially efficacious solution, and will form an integral part of the tanking process which is used to make spaces watertight. For extra protection in those trouble spots, your Cardiff damp proof expert might advise the application of building paper (a specialist foil backed membrane) before the bitumen paint has dried completely.

Tanking: Tanking a room, like a basement or below ground area, is a process of covering any exposed surfaces in a waterproof paint. As this waterproof coating has to be applied to the base surface of walls and floors, all plaster and wall covering must be taken off before any work can begin, and the surfaces in question prepared properly. You can replaster and decorate over the top, as soon as the coating has dried completely. This is an extremely disruptive process because it has to be applied to an entire ground floor or basement level of a property, and it's recommended that you obtain more than one expert's opinion on whether this is really the only answer to your rising damp problems.


To help ease problems with condensation, you can always try dehumidifiers, which for removing moisture from the air, are quite effective. The fact that these products basically cover up the cause of the damp and not get rid of it, is the main disadvantage with dehumidifiers. An experienced damp proofing company in Cardiff will be happy to offer advice on the best solution if you are experiencing damp or mould in any part of your house.


The most trustworthy recommendations for specialists with regards to home improvements are generally friends and relatives. Always obtain at least three different estimates from a variety of companies, and if in any doubt you should ask to look at professional membership certificates and accreditations, before signing up for any damp proofing services.

Keep an eye out for qualifications and membership from bodies such as the Property Care Association or the Damp Proofing Association, or contractors holding the CSRT (Certificated Surveyor in Remedial Treatments) or the Certificated Surveyor of Timber and Dampness (CSTDB) accreditations.

You can be sure that your damp proofing provider is well qualified and has acquired the necessary experience to provide a high quality damp proofing service, if they've got membership of the PCA or DPA. This also offers a guarantee over any work undertaken by one of their membership.
