Damp Proofing Cardiff Wales (CF1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


Below you'll find details about what may cause problems with damp in your home or business in Cardiff, and how you might proceed with fixing them.


Some of the exterior factors that may cause penetrating damp include: damaged or porous brickwork, cracked or loose roof tiles, blocked cavity walls and defective guttering or drainpipes. From within, cracked shower trays, dripping or burst pipework and overflowing sinks or baths, can trigger penetrating damp. If water continues to soak into the woodwork and walls, the noticeable signs in time will be peeling paintwork, damp, dark patches on walls and broken or blistering plaster.

Roof timbers that are constantly damp due to a leaky roof, can be affected by wet rot if this isn't dealt with. Even though brickwork isn't impacted by wet rot, the timbers of your roof can be seriously damaged, and the whole roof may need to be replaced if it becomes structurally unsound. Wet rot can be recognised by the appearance of black fungus on your woodwork and a "spongy" feel to the timbers, together with a unique musty smell from the decaying wood. Upon noticing any of these wet rot indications, prompt action is essential to prevent further structural damage and the potential need for a costly roof replacement.

The means of prevention can be fairly basic, for example inspecting water pipes for leaks, repointing unsound brickwork and cleaning your guttering & roof and checking for leaks. A competent Cardiff damp proof specialist will check all of these areas in order to help prevent any future complications, as part of fixing your issues with dampness.


Condensation Damp Cardiff UK (029)

One of the most common reasons for dampness is condensation, and lots of properties in Cardiff suffer from this. When cool surfaces come into contact with warm, humid air, small water droplets form on those cold surfaces. It's a problem because of inadequate ventilation in areas where there's high humidity, i.e. kitchens, boiler rooms and bathrooms.

Wiping up any droplets of water that appear, and making certain there is sufficient ventilation in the worst affected areas, are amongst the easiest solutions to such problems. Redirecting moist air to the outside of your property in Cardiff, by updating or fitting extractor fans, air bricks and cooker hoods, will help you to resolve this issue.

To find factors which contribute to the problem by sucking in moist air from the outside, a trustworthy Cardiff damp proofing company will do a comprehensive damp proofing survey. Circulation and airflow must be properly regulated to effectively control condensation, and a knowledgeable damp proofing specialist will be able to give advice and offer solutions on this subject.

Damp Proofing Quotes in Cardiff Wales


A damp proof course or membrane has been compulsory on homes constructed in the UK since 1875. If your home was constructed before this time it's perfectly possible that you may not have one installed. If your home was built after this date, but you are still suffering with rising damp problems, it could be that the damp proof membrane or course has been damaged.

If you suppose that you may have rising damp, tide marks on walls, white powdery deposits being found on floor surfaces or forming on walls and crumbling or rotten skirtings, are fair signs that you may be right. It's feasible that you may have a rising damp issue if you have seen one or more of these.

Rising Damp Cardiff Wales

The initial step towards handling your rising damp should be to simply check whether you've got a damp proof course on the exterior walls of your property in Cardiff. To be sure of a satisfactory degree of protection the damp course ought to be above ground level by at least 150 millimetres. If you find this space does not exist, you could dig away the earth to increase it, or if this approach isn't possible, a higher damp proof membrane will need to be put in.

If this is not the cause of the problem and your damp proof membrane is in order, there could be more problematic issues to deal with caused by the moisture coming up from the ground, up through your floors, and into the walls of your property.

Using a number of different procedures, damp proofing experts in Cardiff will quickly identify and resolve rising damp issues. If you've got an older house with no DPM or it is damaged over a wide area, a damp proof cream (such as Dryzone or Permaguard) can be injected into your external walls. This calls for the drilling of holes at evenly spaced intervals in your wall's mortar course and the cream injected with a special nozzle to plug the spaces behind the brickwork down to below ground level.

If the damage to your membrane is too extensive, or if damp proofing cream isn't a satisfactory treatment, you might have to put in a brand new damp proof course. Whilst this level of repair work is a fairly extreme way to solve damp issues, it could be the only real solution when all is said and done.

Another potential option for less severe areas of damage may include painting with a bitumen based, waterproof latex emulsion. Carpeting, tiles or wooden flooring will need to be lifted before any work is done, since it is applied underneath your floor coverings. Also used as an integral part of the tanking procedure to make a room watertight, this is an especially effective solution in cellar areas. Before the bitumen coating has has dried out completely, your Cardiff damp proofing specialist might advise the laying of building paper (a specialist foil backed membrane), for additional protection.

Tanking: Applying a special watertight paint to exposed surfaces in cellars or below-ground areas, known as "tanking," is a method used to waterproof these spaces. Before this application, it is necessary to strip all plaster and wall coverings so the paint can be directly applied to the wall and floor bases, a step crucial for establishing a moisture barrier. Once applied, allowing the coating to dry completely is essential before moving on to replastering and decorating. The extensive nature of tanking, which involves treating the whole lower level of a property, means it's important to seek opinions from several damp proofing experts to determine if it's the appropriate solution for your damp issues. Given its disruptive scale, exploring alternative, less intrusive methods that may be equally effective is advisable.


Dehumidifiers are an effective way of lowering the moisture content in the air, hence for issues with condensation they can help quite a bit. Owing to the fact that dehumidifiers basically hide the cause of the damp and don't cure it, there are issues with this solution. If you are suffering from mould or damp in any part of your home in Cardiff, you should speak to a competent damp proofing company for the best advice.


Family and friends should always be the first choice when you are trying to get recommendations for local specialists. Before hiring any damp proof services, always see if you can get at least two or three quotations from a variety of Cardiff companies. If you're in any doubt about any particular damp proofing company you should ask to look at professional memberships and qualifications.

Look for membership of and qualifications from bodies such as the Property Care Association or the DPA (Damp Proofing Association), or contractors holding the Certificated Surveyor of Timber and Dampness or the Certificated Surveyor in Remedial Treatments (CSRT) professional qualifications.

You can be sure that your damp proofing specialist is properly qualified and has acquired the necessary experience to offer a top notch damp proof service, if they have membership of either the PCA or DPA. Such professional memberships also means there are certain guarantees for any remedial work completed.

Dehumidifier Installation

Dehumidifiers are an essential appliance for maintaining healthy and comfortable indoor air quality, particularly in locations with high humidity levels. Proper installation is paramount to ensure the unit performs at its best and lasts longer.

Picking a suitable location that is obstruction-free and has an electric point nearby is essential before dehumidifier installation. For adequate air circulation, the unit should be situated on a flat surface and kept away from furniture and walls.

Setting up the drainage system correctly is the next step to prevent overflow or water damage. It may require attaching a hose to the unit or connecting the dehumidifier to a drain. The effective operation of the unit necessitates regular maintenance, such as replacing the filter and cleaning.

The dehumidifier's size concerning the space or room it will be installed in is worth considering. An inadequate removal of moisture is the result of using a dehumidifier that is too small, whereas a unit that is too large can lead to excessive dryness and energy wastage. Enhancing the performance and benefits of a dehumidifier can be achieved by meticulously selecting its size and location. Consulting the maker's instructions or seeking the help of a professional is recommended to ensure a safe and successful dehumidifier installation. Indoor air quality can be improved, moisture-related problems reduced, and overall comfort enhanced in homes or workplaces through proper dehumidifier installation and servicing.

Condensation Control

Condensation control is a crucial aspect of maintaining a comfortable and healthy indoor environment. When warm, moist air meets colder surfaces, condensation takes place and leads to the formation of water droplets. Damage to building materials, mould growth, and the deterioration of indoor air quality are potential outcomes of uncontrolled condensation.

Condensation Control Cardiff

Regulating the amount of humidity and promoting air circulation through good ventilation is essential for controlling condensation. Additionally, using double-glazed windows and insulation can help reduce temperature differentials and minimise condensation. Through effective condensation management, potential issues can be avoided, resulting in a more pleasant living or working environment.

Insulation and double-glazed windows can also help to minimise temperature differentials and reduce condensation. Cold surfaces are prevented from coming into direct contact with warm, moist air by insulation, which serves as a thermal barrier. Reducing the temperature difference is one way to decrease the likelihood of condensation forming on surfaces like walls, windows and ceilings. Double-glazed windows are effective at maintaining a consistent inside temperature, which inhibits condensation. They feature 2 panes of glass with an insulating layer between.

To control condensation effectively, one tactic is to tackle the sources of moisture directly. Moisture is released into the air by activities such as cooking, showering and drying clothes indoors. To prevent an excessive build-up of humidity, use exhaust fans and ensure proper ventilation in kitchens and bathrooms. Maintaining optimal indoor humidity levels in areas susceptible to high moisture content is possible with the use of dehumidifiers.

Effective condensation management can help you create a more pleasant working or living environment, free from potential issues. Controlling the indoor environment safeguards the health and well-being of occupants, in addition to protecting buildings. By inspecting seals around windows and doors for gaps during routine maintenance checks, you can identify places where condensation might occur. As our understanding of indoor air quality and building science advances, so too do new condensation control strategies and techniques, providing even more effective ways to ensure a healthy and comfortable indoor environment. In summary, proper insulation, ventilation, moisture source management, and innovative technologies are all essential components of a well-rounded condensation control strategy.

Leave a Review for a Job Well Done

For any Cardiff business, reviews are their driving force, and the difference between a potential client using a particular company, or going elsewhere, may be whether they have excellent reviews online or not. If the damp proofing specialist you hired provided a high quality service, you should reward their efforts by leaving an enthusiastic review. Prospective future clients can benefit from learning of your first hand knowledge, and obviously there are benefits for the company as well. If good or bad reviews helped you to decide on the best damp proofing company in Cardiff to use for your damp proofing project, you'll realise how helpful this can be. Without those customer reviews, you might well have looked at other providers, even if a certain company website appeared really professional.

Leaving a Review

However, can you actually have faith in the customer reviews which are prominently shown on a company website? They may have been "thought up" by an employee of the company, seeking to make their services look better, or were they written by actual customers?

For genuine and frank reviews on any business in Cardiff, Google My Business reviews is a good place to begin. Many will tell you that this is THE review website for determining the reputation of a company, and also has an effect on a business's ranking in search engines. Google My Business's key rival and the second largest local company review website is Bing Places for Business, which is Microsoft's alternative to Google. So as to enhance the profile of a company that worked on your damp proofing project, you can leave an appreciative review in either (or both) of these places, which will in addition build an overall picture of their dependability and working standards, which can be helpful for others searching for similar services. Twitter and Facebook pages are also a good place to leave feedback for your company. These social media sites are a leading part of any small business's media marketing activities. Their marketing message will be strengthened by your approving reviews and give a starting point to neighbours and friends who are trying to find services of a similar nature.

Going 'old school' and traditional is obviously still appropriate, and you could hand write a thankyou letter and send it in to the company. Still essential in an online world, such letters can be scanned or photographed for use on the website, or added to a review portfolio that could be used in one on one meetings with potential clients. However you create a review it's an incredible feeling to think that you might have helped a small local business get a better foothold in the highly competitive market.
