Penetrating damp can be the result of different external factors for instance: porous brickwork, defective drainpipes or guttering, blocked cavities and loose or broken roof tiles. Inside your Cardiff home, penetrating damp can be the result of overflowing sinks or bathtubs, damaged shower trays and leaking or burst water pipes. Visible signs such as blistering or broken plaster, peeling paintwork and damp, dark patches on walls, all point to the reality that these issues have been left unresolved.

You may get wet rot in the timbers on your roof, if you've got a leaking roof, and it's been left untreated for a while. While it's lucky that wet rot doesn't have an impact on brickwork, in the worst outcome, you may need a new roof (extremely expensive!) if your roof timbers become unsound structurally.

An experienced damp proofer in Cardiff will check all these areas in order to help prevent any future complications, as an element of solving your dampness issues.

Damp Proofing Quotes in Cardiff Wales


Homes built since 1875 in the UK have required a damp proof course or membrane to be installed as standard. You may not have a damp course installed on your property in Cardiff if it was built earlier than this. If your home was built after this year, but you're still experiencing rising damp, it might be that the damp proof membrane has been impaired.

It can be notoriously difficult to identify rising damp, nevertheless some giveaway indications are; crumbling or rotten skirtings, a white powdery deposit being found on floor surfaces or forming on walls and "tide marks" on walls. Although the existence of these isn't conclusive, they are all indications of rising damp issues.

Rising Damp Cardiff Wales

The first step towards resolving your rising damp should be to simply check whether you've actually got a DPM on the outside walls of your home in Cardiff. For satisfactory protection it needs to be 150 millimetres above ground level. Where you find that this gap doesn't exist, you can dig away the earth to increase it, or if this approach isn't plausible, a higher DPM will have to be installed.

If your damp proof course is in fact correct and the gap from the ground is not the cause of the problem, moisture could be rising up through your flooring and into your walls, which might be a much more challenging issue.

Using a variety of methods, damp proofing experts in Cardiff can swiftly detect and remedy rising damp. If you've got a somewhat older home with no DPM or one that is damaged over a wide area, a damp proofing cream (such as Permaguard or Dryzone) can be carefully injected into your external walls. This entails drilling holes at evenly spaced intervals in your brickwork and the cream injected with a special nozzle to fill up the spaces behind the brickwork.

In cases where damp proofing injection cream isn't an appropriate remedy, or where your membrane is extensively damaged, installing a complete new damp proof course could be neccessary. Whilst this sort of repair work is a pretty drastic way to solve damp issues, it might be the only real solution at the end of the day.

For minimal areas of membrane damage, another potential solution could be to coat with a waterproof (bitumen based) latex emulsion paint. Because this will be applied beneath any existing floor coverings, tiles, laminate flooring and carpets must be lifted and removed before this operation can commence. This is particularly effectual in basement areas as a part of the "tanking" process to create a room that is watertight. For extra protection in those trouble spots, your Cardiff damp proofing technician might suggest a layer of building paper (a specialist foil backed membrane) before the bitumen coating has has dried out completely.

Tanking: The process of coating exposed surfaces with a waterproof paint in a below ground area such as a cellar is known as tanking. This has to be applied on the base surface of floors and walls, therefore all plaster and wall coverings must be removed and the appropriate surfaces prepared correctly before any work begins. Once this coating has been put on, it must be allowed to dry completely before replastering any walls and decorating on top of it. Since it must be applied to an entire ground floor or basement level of a property, this is a really disruptive process. Therefore, it is a good idea to contact more than one damp proofing specialist to make sure that this really is the only effective option.


Condensation problems can certainly be improved through the use of dehumidifiers, which are an efficient way to remove moisture from the air. Due to the fact that dehumidifiers just hide the cause of the damp and not cure it, there are downsides to this option. If you're experiencing mould or damp in any part of your property in Cardiff, you should contact an experienced damp proofing specialist for the best advice.

Positive Input Ventilation (PIV) may be the ideal solution to alleviate damp issues within your house in Cardiff. If you have noticed damp and mould in your home or condensation around your windows then Positive Input Ventilation can help by reducing the humidity. It accomplishes this by constantly circulating fresh air. This steady replacement and refresh of the air inside your home reduces pollutants and odours, increases air quality and has been proven to improve the everyday life of asthma and allergy sufferers by reducing dust mite allergens in the air. Some considerations for PIV systems is that they work better when installed in a loft space, and your house does have to be fairly airtight. Air, like water, takes the path of least resistance, and any spaces and gaps in doors or windows will let the fresh air out, whilst bringing possible contaminated air in.
