Damp Proofing Northolt Greater London (UB5)


  • Penetrating Damp

  • Condensation

  • Rising Damp


These 3 primary kinds of damp are explained in depth in the following paragraphs, together with tips on prevention and resolution, if you happen to find them in your property in Northolt.


Common exterior factors like: cavity wall problems, broken roof tiles, porous brickwork and damaged gutters or drainpipes, can all be major causes of penetrating damp. Inside a structure, damaged shower trays, overflowing basins or baths and burst or dripping pipework, can cause penetrating damp. If left uncontrolled, woodwork and walls can be severely affected, and the sure evidence of this will be blistering or broken plaster, damp, dark patches on walls and peeling paintwork.

You may get wet rot in the timbers of your roof, if you've got a leaky roof, and it has been neglected for some time. Although it's lucky that wet rot doesn't affect brickwork, in the worst case scenario, you may need to get a new roof (very expensive!) if your roof timbers become structurally unsound. If your roof timbers feel "spongy" to the touch, and a black fungus forms on your woodwork, you could have wet rot in your roof. To avoid further damage and the potential need for expensive roof replacement, it's important to address any signs of wet rot immediately.

The measures for prevention can be fairly basic, for instance repointing dodgy brickwork, inspecting piping for leaks and cleaning your roof & gutters and checking for leaks. If you get hold of a professional damp proofing specialist in Northolt, they will check all these things, and prepare a plan for both dealing with your damp issues and forestalling further occurrences.


Condensation Damp Northolt UK (020)

A common form of damp in Northolt properties, condensation is super easy to spot. When cool surfaces make contact with humid, warm air, minute droplets of water form on those surfaces. If there is not sufficient ventilation in areas of high humidity, such as boiler rooms, bathrooms and kitchens, condensation can frequently be a consequence.

Easy solutions to reduce condensation include wiping up any water droplets as they form and making sure you've got sufficient ventilation in the major problem areas. This might involve the installation or upgrading of cooker hoods, extractors and air bricks to help reroute the humid air outside of your property.

Sometimes damp air is sucked in from the outside, simply making matters even worse. And the most effective way to ascertain the main factors that play a role in the situation, is to get a detailed damp proofing survey carried out by a dependable Northolt damp proofing specialist. The best way to successfully control condensation is to properly regulate air circulation , and your local Northolt damp proofing specialist will offer advice and guidance on how this can be achieved.

Damp Proofing Quotes in Northolt Greater London


Homes constructed since 1875 in the UK have been required to have a damp proof course or membrane to be installed as standard. You may not have a damp course installed on your home in Northolt if it was built earlier than this. It's possible that your damp proof membrane may have been damaged somehow if you are experiencing rising damp issues in a home built after this year.

Rising damp can be rather difficult to distinguish, but some areas to watch out for are; a white powdery deposit being found on floor surfaces or appearing on walls, crumbling or rotten skirtings and tide marks on walls. Whilst the existence of one or more of these is not conclusive, they're all clear indicators of rising damp problems.

Rising Damp Northolt Greater London

Resolving rising damp problems can be as simple as checking your home's external walls to see if you can spot a DPM. For adequate protection it ought to be 150 millimetres (about 6 inches) above ground level. You could dig the surrounding ground away to create this gap if it's currently not enough, or you could put in a damp proof course higher up if the former is not possible.

You could have more challenging issues if you find that your damp proof membrane is okay, and it might be that the moisture is rising from the ground, up through your flooring, and into your home's walls, which is going to be an even more concerning scenario.

Northolt damp proofing experts will swiftly be able to ascertain the cause of your rising damp issues, and using a range of procedures will soon eliminate the problem. Older houses which either have no DPM at all, or have a compromised one which is damaged over a substantial area, can have a damp proofing cream injected into the walls. This cream is injected with a special nozzle into holes drilled at intervals along the wall's mortar course, and before the cream cures it diffuses into the adjoining brickwork forming a barrier that is water-repellent.

If the damp proof cream treatment isn't suitable, or the damage is too extensive to your DPM, a brand new damp proof course may have to be installed. Regrettably this is the most drastic of repair works, however it could be the only answer to your rising damp.

Yet another remedy for less severe areas of damage might include painting with a waterproof (bitumen based) latex emulsion. Because this is going to be applied underneath any existing floor coverings, wood flooring, carpets and tiles will need to be lifted and moved before this process can begin. Also used as a part of the tanking process to create a waterproof room, this is a particularly effective treatment in basements. Before the bitumen paint has completely dried, your Northolt damp proof technician may suggest the laying of building paper (a foil backed specialist membrane), for added protection.

Tanking: To waterproof basements, cellars or below-ground areas, a process known as "tanking" is employed, which includes applying a watertight paint on exposed surfaces. This process demands the removal of all existing wall coverings and plaster to allow direct application to the walls' and floors' base, an essential step for forming a moisture-proof barrier. After the coating is applied, it needs adequate time to dry completely before any replastering or decorative works can be done. Tanking is an extensive method that requires treating the entire lower level of a building, so consulting several damp proofing specialists is wise to determine its suitability for your rising damp problems. Considering the invasive nature of tanking, exploring other less disruptive yet effective alternatives is important.


Issues with condensation can certainly be helped by means of dehumidifiers, which are an efficient way of reducing the moisture content in the air. The fact that these products simply cover up the cause of the damp and don't get rid of it, is the disadvantage with the use of dehumidifiers. To get the best advice if you're suffering from dampness in any part of your house, you should get in touch with a competent damp proofing company in Northolt.

Some of the Benefits of Using Dehumidifiers

The following points outline some key benefits derived from the use of dehumidifiers:

  1. Protects Belongings and Property Structure: Moisture damage to possessions is prevented and the structural soundness of the building is protected by ensuring humidity levels remain low to avoid damp-related issues.
  2. Improvements in Health: Dehumidifiers, by controlling humidity levels, play a significant part in inhibiting the growth of allergens like dust mites and mould, which can trigger respiratory problems and amplify the effects of allergies and asthma.
  3. Odour Reduction: Removes musty odours linked to elevated humidity levels, resulting in a more refreshing and pleasant living space.
  4. Energy Efficiency: Potential energy savings are a benefit of using certain dehumidifiers, as they aid in making air drier and consequently easier for heating systems to heat efficiently.
  5. Prevents Rust and Corrosion: In areas with excessive moisture they help to protect metal tools and appliances from corroding and rusting.
  6. Comfort: The decrease in indoor humidity levels contributes to a more comfortable and cooler environment, improving occupants' living conditions.


As with just about any home improvement project, the most reliable recommendations for a local specialist can be obtained from neighbours and friends. If possible you should always see if you can acquire at least 2 or 3 different quotes from a variety of companies, and before employing any specific damp proofing providers, you should ask to look at qualifications and professional membership certificates, as evidence of their integrity.

Look out for technicians holding the Certificated Surveyor of Timber and Dampness or the Certificated Surveyor in Remedial Treatments (CSRT) qualifications, or companies who are registered members of the DPA (Damp Proofing Association) or the Property Care Association (PCA).

Membership of either the DPA or PCA guarantees that your chosen damp proofing provider is well qualified and has acquired the required experience to provide a high quality damp proof service. Such professional memberships also means there are guarantees for any work performed.

Black Mould

If you are experiencing symptoms of black mould, you might have a problem 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 indications of this sort of mould in your dwelling in Northolt, you should speak to a professional damp proofing company straight away, to get the best treatment.

Black Mould Northolt

Fortunately, there are a number of methods for eliminating black mould. The first strategy uses white vinegar, which is an environmentally-friendly solution. You can apply the vinegar neat to large areas, or mix it fifty, fifty with water for smaller sections. After it has been applied, the solution should sit on the mould for at least an hour before rubbing off.

Another approach involves increasing air flow within your home. It is thought that black mould is more likely to thrive in parts of the house that lack sufficient ventilation. Even though this can't completely eliminate the risk, it's still vital to make certain that the air is flowing out of the house as much as possible. Open up the windows so that fresh air can flow out and in.

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

Dehumidifier Installation Northolt

Dehumidifiers play a vital role in ensuring comfortable and healthy indoor air quality, particularly in regions with high humidity levels. Achieving optimal performance and longevity of the unit hinges on correct installation.

For correct dehumidifier installation, it's vital to select a location that is free from obstructions and has a nearby power source. To facilitate proper air circulation, it's crucial to place the unit on a flat surface and keep it away from walls and furniture.

The next crucial step is to ensure the drainage system is set up properly to prevent water damage or overflow. Connecting the dehumidifier to a drain or attaching a hose to the unit may be necessary. Routine maintenance, such as replacing the filter and cleaning, is essential to ensure the unit operates effectively.

To ensure a successful and safe dehumidifier installation, it's advisable to consult the manufacturer's instructions or seek the assistance of a professional. Moisture-related problems can be reduced, indoor air quality can be improved, and overall comfort enhanced in homes or workplaces through proper dehumidifier installation and servicing.

PIV (Positive Input Ventilation) Northolt

PIV (Positive Input Ventilation) might be an ideal solution to reduce damp issues within your house in Northolt. Alleviating mould and damp in your property or condensation around your windows can be accomplished by reducing the humidity through PIV. Achieving this is accomplished by the constant supply of fresh air. Constantly refreshing and replacing the air inside your property can have a positive impact on air quality, reducing odours and pollutants, and decreasing dust mite allergens, which has been proven to improve day-to-day life for allergy and asthma sufferers. One thing about PIV systems is that it works better when installed in a loft, and your home does have to be fairly airtight. Spaces and gaps in windows or doors can cause fresh air to escape while allowing polluted air to enter, as air, similar to water, takes the path of least resistance.

Cementitious Tanking

For preventing the penetration of water in cellars and underground spaces, cementitious tanking is a popular method. To the walls and floors of the space, a cement-based waterproofing system is applied as part of this process. The tanking material can be pre-manufactured or mixed at the work site and comes in a range of grades suitable for various substratum.

Cementitious Tanking Northolt

Cementitious tanking has the potential to provide a long-lasting and durable barrier against water ingress, but correct application is crucial for maximum effectiveness. Prior to application, the surface must be clean, dry, and free from any contaminants or loose material to achieve the best possible results.

Professional installation by a competent damp proofing specialist is suggested to attain a long-lasting and high-quality outcome. Cementitious tanking, when properly installed, can be an effective and reliable solution for waterproofing basements and cellars in Northolt.

Woodworm Treatment and Prevention in Northolt

Woodworm is a common problem that can cause significant damage to wooden structures, furniture, and other objects. The larvae of certain types of beetles gnaw away at the timber, causing it to weaken and deteriorate over time. However, there are several ways to treat and prevent woodworm infestations.

Identifying the type of beetle responsible for a woodworm infestation is the initial step in effectively solving the problem. Depending on the specific species, different treatments may be necessary to eradicate the pests and prevent further damage. Seeking the assistance of a seasoned woodworm professional is highly recommended, as they can conduct a thorough evaluation of the situation and offer expert advice on the most suitable treatments to deal with the infestation and safeguard the integrity of the wood.

Insecticides are a common method of treating woodworm, and can be applied in gel or liquid form. These treatments penetrate the timber and eliminate the larvae. For more severe infestations, fumigation might be necessary. Fumigation involves sealing the affected area and discharging a gas into the space to eliminate the larvae.

So as to prevent future woodworm infestations, it is important to make sure that the environment isn't conducive to their growth. This can be accomplished through maintaining correct humidity levels, good ventilation, and treating any existing woodworm as soon as it is identified.

By conducting regular inspections of your property, you can detect infestations of woodworm at an early stage, facilitating swift and effective treatment to reduce damage. It is also critical to deal with any water damage, as moist wood tends to attract woodworm. To prevent infestations of woodworm in wooden objects or furniture, ensure they are kept clean and dry at all times.

Vigilantly monitoring for signs like deteriorating brickwork, damp spots or crumbling plaster is paramount. DPC replacement necessitates the removal of the old, compromised barrier and the installation of a new, resilient one. This intricate process typically demands the expertise of seasoned professionals, as it hinges on meticulousness and precision to guarantee an impenetrable seal against moisture intrusion.

The choice of materials for the new Damp Proof Course can encompass a range of options, from traditional approaches like slate or bitumen to more modern solutions such as chemical injections. A successful DPC replacement not only prevents further moisture-induced damage but also helps maintain a healthy indoor environment and protects the value of your Northolt home.
