  • Penetrating Damp

  • Condensation

  • Rising Damp


Below you will find info on what might be causing damp problems in your home or business in Coulsdon, and precisely how you may set about fixing them.


Common external issues that can lead to penetrating damp include: blocked cavity walls, damaged or porous brickwork, loose or cracked roof tiles and damaged downspouts or guttering. In the interior of your house it can be due to damaged shower trays, burst or leaky pipes and overflowing sinks or baths. Woodwork and walls can be impacted if left unchecked, and will be noticeable as flaking paintwork, dark, damp patches on walls and broken or blistering plaster.

If you've got a leaky roof and it has been neglected for some time, it can cause wet rot in the timbers of your roof. This could prove to be extremely expensive, because if worse comes to worst the structural integrity of your roof timbers could be compromised, with the result that you are going to need an entire new roof. If a black fungus starts to appear on any woodwork and the timber in your roof feels "spongy" to touch, you may have a case of wet rot. Upon detecting any of these wet rot indicators, it is crucial to take swift action to avert further harm and the likelihood of a pricey roof replacement.

Simple actions like repointing dodgy brickwork, cleaning your roof & gutters and checking for leaks and examining pipes for leaks, are the basic preventative measures. As an integral part of fixing your dampness problems, a professional Coulsdon damp proofing specialist will check these things, in order to help prevent any further problems.


Condensation Damp Coulsdon UK (020/01737)

One of the most common causes of damp is condensation, and numerous properties in Coulsdon suffer from this. When a cold surface comes into contact with warm, humid air, water collects as small droplets upon that surface. Poor ventilation in areas with high humidity, such as in boiler rooms, bathrooms and kitchens, is the most frequent reason for condensation.

There are a couple of easy ways of managing condensation, and these are ensuring that troublesome areas have adequate ventilation, and wiping droplets away as they appear on surfaces. You might need to fit or update air bricks, extractor fans and cooker hoods, in order to redirect excess moist air from your property in Coulsdon.

There may be issues with sucking in damp air from the outside, and by performing an in-depth damp proofing survey an expert in Coulsdon will find factors that bring about the problem. A specialist on this subject will be able to offer guidance, information and solutions on this matter, because in order for condensation problems to be controlled, any airflow and circulation in the home must be effectively regulated.

Damp Proofing Quotes in Coulsdon Greater London


A damp proof course or membrane has been installed as standard on houses built in the UK since 1875. It's perfectly possible that you may not have one fitted if your property in Coulsdon was built before this time. If you're experiencing rising damp in a house built after this time it might be that your DPM has been damaged in some way.

Although hard to distinguish, a white powdery deposit being discovered on floor surfaces or forming on walls, tide marks on walls and rotten or crumbling skirtings, are all giveaway clues that you might have rising damp. It is possible that you may have a rising damp issue if you have spotted one or more of these.

Rising Damp Coulsdon Greater London

The first step towards handling your rising damp should simply be to check whether or not you've got a DPM on the outside walls of your home in Coulsdon. For satisfactory protection it needs to be 150 millimetres above ground level. You can dig the surrounding ground away to create this space if it's currently not sufficient, or you can put in a DPM (damp proof membrane) higher up if the first option is not plausible.

If this is not the problem and your damp proof course is in fact correct, there might be more challenging issues to deal with caused by the moisture rising up from the ground, up through your floor, and into your walls.

Damp proofing specialists in Coulsdon can swiftly identify and eliminate rising damp problems using a number of procedures. A damp proofing cream (such as Dryzone) can be injected into your walls if you've got an older home with no DPM, or one that's damaged over a substantial area. This entails the drilling of holes at intervals in your brickwork and the cream injected with a special nozzle to plug the spaces behind the brickwork down to beneath ground level.

In instances where damp proofing injection cream isn't a satisfactory solution, or when your DPM is severely damaged, installing a complete new damp proof course might be neccessary. While this sort of repair work is a fairly extreme way to solve rising damp problems, it could be the only real solution in the final analysis.

Damp Proofers Coulsdon (CR5)

Another potential remedy for less severe areas of damp course damage may include painting on a layer a waterproof (bitumen based) latex emulsion coating. This has to be applied beneath your floor coverings, so wood flooring, tiles and carpets will have to be lifted before any work is done. This is especially effective in basements as an integral part of the "tanking" procedure to create a room that is watertight. Your Coulsdon damp proof specialist may suggest applying building paper (a foil backed specialist membrane) before the bitumen paint has completely dried out, extra protection in these trouble spots.

Tanking: Applying a special watertight paint to exposed surfaces in basements or below-ground areas, known as "tanking," is a method used to waterproof these spaces. Before this application, it is necessary to strip all wall coverings and plaster 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 to remove moisture from the air, so for problems with condensation they can be of help. The fact that these products basically cover up the cause of the damp and not cure it, is the trouble with dehumidifier use. To obtain the best advice if you are suffering from damp or mould in any area of your home, you can contact an experienced damp proofing specialist in Coulsdon.

The Benefits of Using Dehumidifiers

  3. Protects Belongings and Property Structure: By preventing damp-related issues and safeguarding belongings from moisture damage, lower levels of humidity ensure the structural soundness of the premises is maintained.
  4. Improvements in Health: By diminishing the levels of humidity, dehumidifiers play a crucial role in curtailing the spread of mould and dust mites, frequent triggers of respiratory conditions and aggravators of asthma and allergy symptoms.
  5. Overall Comfort: The decrease in indoor humidity levels contributes to a more comfortable and cooler environment, improving occupants' living conditions.


The most reliable recommendations for specialists when it comes to home improvements are generally family and friends. Where possible you should try to obtain at least 2 or 3 different quotes from a range of companies, and before hiring any specific damp proof services, you can ask to see professional membership certificates and qualifications, as proof of their integrity.

Professional Coulsdon damp proofing specialists should be members of either the Damp Proofing Association (DPA) or the PCA (Property Care Association), or have qualifications from the Certificated Surveyor in Remedial Treatments (CSRT) or the Certificated Surveyor of Timber and Dampness (CSTDB).

You can guarantee that your damp proofing specialist is well qualified and has acquired the appropriate practical experience to provide you with a top notch damp proof service, if they've got membership of the PCA or DPA.

Problems With Black Mould in Coulsdon

If you are experiencing signs of black mould, you may have an issue with Stachybotrys chartarum. This fungus is highly toxic and produces a slime head called conidia. It is known as a leading cause of indoor air pollution and is also considered a health hazard. If you see signs of this type of mould in your house in Coulsdon, you ought to speak to a qualified damp proofing company straight away, to get the best treatment.

Black Mould Coulsdon

The first step in eliminating mould is to clean the affected area with soapy water. You should also use a disinfectant such as bleach, which should kill mould spores. White vinegar and hydrogen peroxide are also effective disinfectants. However, you must be very careful when using bleach, as it may burn and irritate your eyes. Also, ensure good ventilation in the room where you're working, to help clear away the fumes.

Another option is to use a baking soda and water paste to treat the mould. This solution has a pH of 2.5, making it an effective antibacterial. Hydrogen peroxide is another treatment that can be effective for eliminating black mould. It's a natural, 3 in 1 solution that is safe to use, particularly on surfaces that are porous.

Condensation Control

Vital for maintaining a healthy and pleasant indoor environment is the control of condensation. Condensation occurs when warm, moist air comes into contact with cooler surfaces, leading to the formation of water droplets. The consequences of uncontrolled condensation include damage to building materials, mould growth, and the deterioration of indoor air quality.

Condensation Control Coulsdon

Effective control of condensation necessitates adequate ventilation, which regulates the level of humidity and facilitates the circulation of air. Reduction of differences in temperature and minimisation of condensation can be achieved by using insulation and double-glazed windows. By effectively managing condensation, you can prevent potential problems and create a more pleasant living or working environment.

Additionally, the use of insulation and double-glazed windows can help reduce temperature differentials and minimise condensation. Moist, warm air cannot come into direct contact with cold surfaces because of insulation, which acts as a thermal barrier. The temperature difference has to be reduced in order to decrease the likelihood of condensation forming on surfaces like walls, ceilings and windows. Double-glazed windows are effective at maintaining an even indoor temperature, further inhibiting condensation, as they feature 2 panes of glass with an insulating layer in between.

Another way to control condensation effectively is to deal with moisture sources head-on. Moisture is released into the air by activities like drying clothes indoors, cooking and showering. Proper ventilation and exhaust fans in kitchens and bathrooms can help to prevent excessive humidity buildup. Acceptable indoor humidity levels can be maintained in areas which are liable to high moisture content by using dehumidifiers.

To create a more comfortable living or working environment, you can effectively manage condensation and prevent potential problems. A controlled indoor environment not only protects the structural integrity of buildings but also ensures the health and well-being of occupants. Routine maintenance checks, such as examining seals around doors and windows for gaps, can help identify locations where condensation might occur. As our understanding of indoor air quality and building science advances, new technologies and strategies for condensation control continue to emerge, providing even more effective ways to ensure a comfortable and healthy indoor environment. To sum up, for a wide-ranging condensation control strategy, proper insulation, moisture source management, ventilation, and cutting-edge technologies are all essential elements.
