  • Penetrating Damp

  • Condensation

  • Rising Damp


In paragraphs that follow, we will consider what causes such damp problems, and how you can set about resolving them, and stopping them from happening in the first place.


There are numerous external factors that can cause penetrating damp, and included in these are: blocked cavities, damaged gutters or drainpipes, cracks in brickwork and broken or loose roof tiles. Internal reasons behind penetrating damp could be overflowing bathtubs or basins, burst or leaky pipes and cracked shower trays. If water continues to soak into the woodwork and walls, the obvious signs in time will be peeling or bubbling paintwork, damp, dark patches on walls and broken or blistering plaster.

If you have a leaky roof and it's been left untreated for an extended period of time, it can cause wet rot to develop in your roof timbers. Wet rot can't spread into your brickwork, but it can mean that in the worst case scenario your roof timbers become structurally unsound, requiring a new roof. Wet rot can be identified by the appearance of black fungus on your woodwork and a "spongy" feel to the rafters, coupled with a unique musty smell from the decaying timber. For the sake of avoiding further structural harm and the potential need for costly roof replacement, it is essential to deal with any signs of wet rot right away.

Some basic measures can help prevent this, such as: repointing unsound brickwork, examining pipework for leaks and cleaning your rain gutters & roof and checking for leaks. An experienced damp proofer in Isleworth will check all these areas in order to help prevent any future complications, as an element of resolving your dampness issues.


Condensation Damp Isleworth UK (020)

Quite simple to identify and the cause of damp in many Isleworth properties, condensation is extremely common. Water forms as tiny droplets on a cold surface, when warm, moist air makes contact with it.

You can reduce the volume of moist and humid air that's present in your dwelling by upgrading or installing extractor fans, air bricks and cooker hoods.

Airflow and circulation has to be properly regulated to effectively minimise condensation problems, and a professional damp proofing specialist will offer advice and solutions on this topic.

Damp Proofing Quotes in Isleworth Greater London


Ever since 1875, a damp proof course has been installed as standard in all houses constructed in the UK. You may not have a damp course on your property or home in Isleworth if it was built earlier than this. If your house was constructed after this year, but you are still experiencing rising damp, it may be that your damp proof membrane has been impaired.

If you believe that you might have rising damp in your home, a white powdery deposit being discovered on floor surfaces or appearing on walls, crumbling or rotten skirtings and tide marks on walls, are fair signs that you may be right. Although the existence of one or more of these is not conclusive, they are all clear indications of rising damp problems.

Rising Damp Isleworth Greater London

Fixing rising damp problems can be as easy as checking your home's exterior walls and seeing if you can spot a DPM. It needs to be 150mm (approximately 6 inches) above the level of the ground for adequate protection. You can dig away the surrounding soil to create this gap if it is currently not sufficient, or you could install a higher damp course if the first option is not plausible.

If this is not the root cause of the problem and your damp proof membrane is correct, there could be more challenging issues to resolve caused by the moisture rising up from the ground beneath, up through your floors, and into the walls.

Isleworth damp proofing specialists will swiftly be able to determine the explanation for your rising damp, and employing a variety of procedures will quickly resolve the problem. If you have an older house with no damp proof membrane or one that's damaged over a considerable area, a damp proof cream (such as Dryzone) can be injected into your walls. Holes will be drilled at intervals in the mortar joint, and a nozzle is used to inject the special cream, which then soaks into the surrounding brickwork before curing to form an effective water-repellent barrier.

If the deterioration of the damp course membrane is too severe, or if damp proofing cream isn't a satisfactory treatment, you may need to put in a brand new damp proof course. Unfortunately this is the most drastic of repair works, however it may be the only solution to your rising damp.

Another remedy for less severe areas of membrane damage could include painting with a bitumen based, waterproof latex emulsion. As this will be applied underneath any existing floor coverings, tiles, wood flooring and carpeting will need to be lifted and removed before this process can commence. Also used as an integral part of the "tanking" process to make a space watertight, this is an especially effectual treatment in basements. Before the bitumen paint has completely dried, your Isleworth damp proofing expert may recommend the application of building paper (a specialist foil backed membrane), for further protection.

Tanking: The process of covering exposed surfaces with a waterproof paint in a below ground area such as a basement is known as tanking. This has to be applied at the base level of floors and walls, and so any plaster and wall coverings must be removed and the relevant surfaces correctly prepared before work commences. When the coating has been applied and dried, it's then the time to replaster any wall surfaces and decorate over it. Because it has to be applied to an entire ground floor or basement level of a building, this is an incredibly disruptive process. Therefore, it's preferable to call in at least three damp proofing companies to make sure that this really is the only possible option.

The installation of dehumidifiers is essential to maintain a comfortable and healthy indoor air quality, particularly in spaces with high levels of humidity. Proper installation is crucial for the optimal performance and longevity of the unit.

Dehumidifier Installation Isleworth

Before installing a dehumidifier, one must carefully select an obstruction-free location with an electricity socket nearby. Sufficient air circulation requires placing the unit on a flat surface and keeping it away from walls and furniture.

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 routine maintenance, such as cleaning or replacing the filter.

The size of the dehumidifier concerning the space or room it will be installed in should be taken into account. To ensure a successful and safe dehumidifier installation, it's advisable to consult the maker's instructions or seek the assistance of a professional.

Considerations for PIV systems include the requirement for a reasonably airtight house and optimal performance when installed in a loft. Similar to water, air will take the path of least resistance, so gaps and spaces in windows or doors can lead to fresh air escaping and polluted air entering.

Problems With Black Mould in Isleworth

Black mould is a common problem in houses in Isleworth, especially those made of wood. This fungus is considered to be toxic. It produces slime heads and conidia, which are a sign of its presence. If you find this form of mould in your home in Isleworth, it is vital to remove it right away. If you think you could have black mould, it's important to have it checked by a professional. Experienced damp proofing specialists in Isleworth can conduct tests and provide you with a free quote.

Black Mould Isleworth

Fortunately, there are various strategies for getting rid of black mould. The first strategy uses white vinegar, which is an eco-friendly solution. You can apply the vinegar neat to large areas, or mix it 50:50 with water for smaller patches. After it has been applied, the vinegar solution should sit on the mould for at least sixty minutes before wiping off.

Another method involves increasing ventilation within your home. It is thought that mould is more likely to grow in parts of the house that lack adequate ventilation. Even though this cannot completely eliminate the risk, it's still vital to make certain that the air is getting out of the house as much as possible. Open up the windows so that clean air can flow out and in.

Black mould is a fungus that is highly infectious. It can cause life-threatening infections in people with weak immune systems. It frequently evolves in cracks and other areas where the air cannot circulate. Symptoms can include large warts and cauliflower-like lesions on the skin. The area may also be swollen and red. It can even affect the nails. Black mould is generally caused by water leaks, airborne moisture or condensation.

Condensation Control

Control of condensation is crucial for 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. Uncontrolled condensation can lead to the growth of mould, damage to building materials, and the deterioration of indoor air quality.

Condensation Control Isleworth

Regulating humidity levels and promoting the circulation of air through proper ventilation is essential for controlling condensation. Reduction of differences in temperature and minimisation of condensation can be achieved by using insulation and double-glazed windows. Creating a more pleasant working or living environment is achievable by effectively managing condensation, which helps prevent potential issues.

In addition to reducing temperature differentials and minimising condensation, insulation and double-glazed windows can also help. Cold surfaces are prevented from coming into direct contact with moist, warm air by insulation, which acts as a thermal barrier. Condensation is less likely to form on surfaces like walls, windows and ceilings if the temperature difference is reduced. Double-glazing is effective at maintaining an even indoor temperature, which inhibits condensation. It features two panes of glass with an insulating layer in between.

To control condensation effectively, one approach is to tackle the sources of moisture head-on. Showering, drying clothes indoors and cooking and similar activities can all release moisture into the air and cause problems. Good ventilation and exhaust fans in kitchens and bathrooms can help to prevent an excessive build-up of humidity. Using dehumidifiers in areas prone to high moisture content can also help maintain optimum indoor humidity levels.

By effectively managing condensation, you can prevent potential issues and create a more comfortable living or working environment. The health and well-being of occupants, as well as the structural integrity of buildings, are both safeguarded by a controlled indoor environment. Locations where condensation might occur can be identified by conducting regular maintenance checks, such as examining seals around doors and windows for gaps. As building science and indoor air quality knowledge advances, new condensation control technologies and strategies emerge, offering even more effective ways to ensure a comfortable and healthy indoor environment. To summarise, proper ventilation, insulation, moisture source management, and cutting-edge technologies are all essential for a wide-ranging condensation control strategy.
