There are basically 3 key problem areas which are likely to cause dampness in your property in Harlesden:

Damp Proofing Harlesden Greater London (NW10)


  • Penetrating Damp

  • Condensation

  • Rising Damp


These three key kinds of damp are described in more detail in this article, along with recommendations for prevention and resolution, if you should discover them in your property in Harlesden.


Penetrating damp can be caused by various external factors such as: broken or loose roof tiles, defective drainpipes or gutters, unsound brickwork and cavity wall issues. Inside a building, it can be triggered by overflowing baths or basins, burst or leaky water pipes and damaged shower trays. If left to continue leaking these elements enable water to seep into walls and woodwork, which over time lead to blistered or broken plaster, flaking paintwork and dark, damp patches on walls.

If you have a leaking roof and it has been left untreated for some time, it can cause wet rot in the timbers of your roof. If worse comes to worse, you might even need to replace the whole roof, since wet rot can cause your roof timbers to become dangerous and structurally unsound. If black fungus starts to appear on your woodwork and the timber in your roof feels "spongy" to the touch, you might have an issue with wet rot.

Preventative maintenance can be basic, such as inspecting pipes for leaks, cleaning your rain gutters & roof and checking for leaks and repointing brickwork. If you employ the services of a professional Harlesden damp proofing firm, they will check all these elements as part of your overall damp proofing program.


Condensation Damp Harlesden UK (020)

A common form of damp in many houses in Harlesden, condensation is super easy to spot. When cool surfaces make contact with warm, humid air, small droplets of water form on those cold surfaces. It often manifests due to poor ventilation in places where there's high humidity, i.e. bathrooms, kitchens and boiler rooms.

There are two straightforward ways of managing condensation issues, and these are making sure that trouble spots have good ventilation, and wiping water droplets away as they appear on surfaces. To help redirect the humid air from your home, you might need to fit or update extractor fans, cooker hoods and air bricks.

By conducting a comprehensive damp proofing survey, a respectable Harlesden company will find any areas where moist air is drawn in from the outside, simply exacerbating the problem. The best way to successfully control condensation is to regulate airflow correctly, and your local Harlesden damp proofing specialist will offer advice and guidance on how this can be accomplished.

Damp Proofing Quotes in Harlesden Greater London


Since 1875, a damp proof course has been compulsory in all homes constructed in the United Kingdom. You might not have a damp course installed on your home in Harlesden if it was constructed earlier than this. It's possible that your damp proof course might have been damaged if you are experiencing rising damp issues in a home built after this date.

If you believe that you might have rising damp in your home, tide marks on walls, crumbling or rotten skirting boards and a white powdery deposit being discovered on floor surfaces or appearing on walls, are good signs that you might be correct. While the existence of these isn't conclusive, they're all indications of rising damp issues.

Rising Damp Harlesden Greater London

Resolving rising damp problems can be as easy as checking your property's external walls to see if you can spot a DPM. To be certain of an adequate measure of protection the damp course should be above ground level by no less than 150mm. Where you find that this gap does not exist, you could dig away the soil to increase it, or if this process is not feasible, a higher DPM will have to be put in.

You may have more challenging issues if you discover that your DPM (damp proof membrane) is fine, and it could be that the moisture is seeping up from the ground, through your flooring, and into the walls, which is going to be even more worrying.

Using a number of different procedures, damp proofing experts in Harlesden will swiftly detect and eliminate rising damp. If you have a somewhat older property with no damp proof membrane or one that's damaged over an extensive area, a damp proofing cream can be injected into your wall. This cream is injected with a special nozzle into evenly spaced holes drilled along the wall's mortar course, and before the cream can set it turns into liquid and soaks into the adjoining brickwork forming a barrier that is water-repellent.

If the damage to your membrane is too severe, or if damp proofing cream injection isn't an appropriate solution, you might need to put in a new damp proof course. This is the most drastic of repair works, but it might be the only solution to your rising damp.

For smaller areas of membrane damage, yet another potential option would be to coat with a waterproof (bitumen based) latex emulsion. This is applied underneath your current floor coverings, so wood flooring, carpets and tiles must be lifted prior to work being done. This is especially effective in basement areas as part of the tanking procedure to create a room that's watertight. Before the bitumen coating has completely dried, your Harlesden damp proof specialist might suggest the application of building paper (a foil backed specialist membrane), for additional protection.

Tanking: In below ground areas for example cellars, "tanking" is the process where any surfaces that are exposed are painted with a waterproof coating. This has to be applied on the base surface of floors and walls, so all wall coverings and plaster must be removed and the appropriate surfaces prepared properly before any work begins. When this coating has been applied, it should be allowed to dry completely before replastering any wall surfaces and decorating on top of it. This is an exceedingly disruptive process since it must be applied to a whole ground floor or basement level of a building, and it is wise to get more than one specialist's opinion on whether this is the only resolution to your damp problems.


Condensation issues can definitely be helped by means of dehumidifiers, which are an efficient way of lowering the moisture content in the air. The main drawback with dehumidifier use in seeking to stop damp is that they only mask the cause of the damp, don't get rid of it. To get the most reliable advice if you are suffering from dampness in any part of your property, you should speak to a professional damp proofing specialist in Harlesden.


The most reliable recommendations for professionals with regards to home improvement projects are generally neighbours and friends. Before hiring any damp proofing services, you should always try to get at least three quotations from different Harlesden companies. If you're in any doubt about any specific company you should ask to see professional membership certificates and accreditations.

Keep an eye out for membership of and qualifications from trade bodies such as the Damp Proofing Association or the Property Care Association, or contractors holding the Certificated Surveyor of Timber and Dampness (CSTDB) or the Certificated Surveyor in Remedial Treatments accreditations.

Membership of either the PCA or DPA guarantees your selected damp proofing specialist is properly qualified and has acquired the appropriate experience to offer a high quality damp proof service. Any remedial work supplied by any one of their members also comes with a guarantee.

Woodworm Treatments in Harlesden

Woodworm infestations are a common problem in Harlesden, particularly in properties that are older. The woodworm larvae feast on wood, causing damage and weakening structures over time. If left untreated, woodworm can cause a lot of damage and compromise the structural integrity of buildings. Fortunately, there are effective woodworm treatment options available in Harlesden.

Identifying the kind of beetle responsible for a woodworm infestation is the starting point of successfully 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 an extensive evaluation of the situation and offer expert guidance on the most suitable treatments to tackle the infestation and protect the integrity of the timber.

Insecticides are among the most effective methods for treating woodworm, and these can be applied in liquid or gel form. These treatments penetrate the timber and exterminate the larvae. This strategy is most effective for minor infestations, and a professional can determine whether this is the best option. For more serious infestations, fumigation may be necessary. This involves sealing the affected area and discharging a gas into the space to exterminate the woodworm larvae. Fumigation is a much more invasive treatment, but for large infestations, it is frequently the best option.

Prevention is also key in avoiding future woodworm infestations. This can be achieved through frequent inspections, maintaining good humidity levels and ventilation, and treating any existing woodworm as soon as it's identified.

Regularly inspecting the premises is an effective way to spot infestations of woodworm early on, enabling speedy action to be taken to minimise damage. In addition, it's essential to deal with any water damage, as wet wood can attract woodworm. To prevent woodworm infestations in wooden furniture or other wooden items, it is crucial to maintain their cleanliness and dryness.

All in all, it is necessary to use an experienced woodworm specialist in Harlesden to identify, assess, and treat any infestations to maintain the structural integrity of the building.

Condensation Control

Crucial for maintaining a comfortable and healthy indoor environment is the control of condensation. The contact between colder surfaces and warm, moisture-laden air causes the formation of water droplets through condensation. The consequences of uncontrolled condensation include mould growth, damage to building materials, and the deterioration of indoor air quality.

Condensation Control Harlesden

Achieving condensation control relies on adequate ventilation, which regulates the level of humidity and ensures adequate air flow. Insulation and double-glazed windows can be employed to help minimise condensation and reduce differences in temperature. By effectively managing condensation, you can prevent potential issues and create a more pleasant working or living environment.

In addition to reducing temperature differentials and minimising condensation, insulation and double-glazed windows can also help. Insulation is a thermal barrier that prevents cold surfaces from coming into direct contact with moist, warm air. This reduction in temperature difference decreases the likelihood of condensation forming on surfaces like ceilings, walls and windows. Double-glazed windows, featuring 2 panes of glass with an insulating layer between, are effective at maintaining an even interior temperature, further inhibiting condensation.

Direct addressing of the sources of moisture is another approach to effective condensation control. Activities like cooking, showering and drying clothes indoors release moisture into the air. To prevent excessive humidity buildup, use exhaust fans and ensure adequate ventilation in kitchens and bathrooms. In areas at risk of high moisture content, dehumidifiers can help maintain optimal indoor humidity levels.

A more pleasant working or living environment can be created by effectively managing condensation and preventing potential problems. Interior environments that are controlled not only protect buildings but also safeguard the well-being and health of occupants. Regular maintenance checks, including checking seals around windows and doors for gaps, can help you identify places where condensation is likely to occur. Our advancing understanding of building science and indoor air quality leads to the emergence of new condensation control strategies and techniques, providing even more effective ways to ensure a healthy and comfortable indoor environment. In summary, proper insulation, moisture source management, ventilation, and innovative technologies are all essential components of a wide-ranging condensation control strategy.
