  • Penetrating Damp

  • Condensation

  • Rising Damp


We will explore these three significant types of damp problems, and come up with tips on how to prevent them and resolve them, if they occur.


Penetrating damp in buildings can be caused by a whole host of external factors for example: cracks in brickwork, blocked cavities, cracked or loose roof tiles and damaged gutters or downpipes. Inside your Finchley home, it can be the result of cracked shower trays, burst or dripping pipework and overflowing basins or bathtubs. Obvious signs like blistering or broken plaster, flaking paintwork and dark, damp patches on walls, all point to the reality that these issues have been left unresolved.

If neglected for an extended period of time, a leaky roof can cause wet rot in your roof timbers. Wet rot does not spread into brickwork, but having it can mean that in the worst case the timbers of your roof become structurally dangerous, requiring a new roof. There are various indicators of wet rot which aren't hard to spot, the principle ones being; the presence of black fungus on woodwork, a "spongy" feel to the timbers and a musty smell of decaying wood. If you detect any of these wet rot symptoms, it is imperative to address the issue promptly to prevent further damage and the potential for a costly roof replacement.

To prevent this, there are some elementary preventative measures you can take: cleaning your roof & guttering and checking for leaks, repointing unsound brickwork and examining piping for leaks. If you get hold of a knowledgeable damp proofing service in Finchley, they will check all of these areas, and prepare a plan for both fixing your damp issues and forestalling further episodes.


Condensation Damp Finchley UK (020)

Lots of dwellings in Finchley have problems with condensation, and this is one of the most common factors behind damp. Tiny droplets of water form on colder surfaces when humid, warm air comes into contact with these surfaces. Where high humidity is present, as in boiler rooms, kitchens and bathrooms, condensation is often caused by poor ventilation.

Wiping up any droplets that appear, and making sure there is sufficient ventilation in the affected areas, are among the simplest answers to such problems. To help redirect the humid air from your home, you might need to install or update extractors, air bricks and cooker hoods.

The best way to establish the main areas that give rise to the situation, is to have an in-depth damp proofing survey carried out by a reliable Finchley damp proofing specialist. Occasionally moist air is drawn in from the outside, simply making matters even worse. So as to manage condensation problems, it is essential that circulation and airflow in the home is properly regulated, and by chatting to a specialist on this topic, you will get information and guidance for solving these issues.

Damp Proofing Quotes in Finchley Greater London


Homes built since 1875 in the United Kingdom have been required to have a damp proof course to be fitted as standard. It's quite possible that you might not have one installed if your house in Finchley was constructed in the years before this. If you are experiencing rising damp in a home built after this time it is possible your damp proof course or damp proof membrane has been damaged in some way.

Although tricky to identify, tide marks on walls, a white powdery deposit forming on walls or being discovered on floor surfaces and rotten or crumbling skirting boards, are all giveaway clues that you might have rising damp. If you notice or think that you may have any of these signs, it is possible that you've got a problem with rising damp.

Rising Damp Finchley Greater London

Remedying rising damp issues can be as straightforward as checking your outside walls to see if you can spot a damp proof course. For satisfactory protection it needs to be 150mm (about 6") above the level of the ground. If this is not the situation you can dig away the ground to generate this space, or if this is not plausible, you can install a DPM higher up.

If your damp proof membrane (DPM) is correct and the gap is not the explanation for the problem, dampness could be coming up through your floors and into your walls, which might be a more serious issue.

Using a range of methods, damp proofing experts in Finchley will swiftly identify and eliminate rising damp. A damp proofing cream (such as Dryzone) can be injected into your walls if you have an older property with no damp proof membrane, or one that's damaged over an extensive area. This entails the drilling of holes at intervals along the wall's mortar course and the special cream injected with a nozzle to plug the gaps behind the brickwork.

In instances where damp proofing injection cream isn't an appropriate solution, or when your damp course membrane is too severely damaged, installing a brand new damp proof course might be neccessary. Unfortunately this is taking repair work to the extreme, but it may be the only remedy for your rising damp.

Yet another solution for minimal areas of damage could include painting on a layer a bitumen based, waterproof latex emulsion coating. Laminate flooring, carpeting or tiles will have to be lifted prior to work being done, as it's applied underneath your floor coverings. In basements this is an especially effectual treatment, and will form an integral part of the "tanking" procedure that is used to make rooms watertight. For added protection in those troublesome areas, your Finchley damp proofing expert may recommend the application of building paper (a foil backed specialist membrane) before the bitumen coating has completely dried.

Tanking: Tanking an area, like a cellar or part below ground space, is the process of covering exposed surfaces with a waterproof paint. Because this coating has to be applied on the base surface of walls and floors, any plaster and wall covering must be removed before work commences, and all surfaces properly prepared. Once this coating has been put on, it should be allowed to dry out completely before replastering and decorating on top of it. You must always get more than one specialist's opinion on whether this really is the only cure for your damp problems, because this is a really disruptive process as it has to be applied to a whole ground floor or basement level of a building.


Dehumidifiers are an efficient way to remove moisture from the air, so for issues with condensation they can help quite a bit. The main issue with dehumidifiers in endeavouring to reduce dampness is that they just mask the cause of the damp, not cure it. To get the most reliable advice if you're experiencing damp in any part of your property, you can speak to a professional damp proofing company in Finchley.

The Benefits of Using Dehumidifiers

Below are just some of the benefits of using dehumidifiers:

  1. Health Improvements: By reducing humidity levels, dehumidifiers help mitigate the growth of mould and dust mites, common allergens that can cause respiratory issues and aggravate allergies and asthma.
  2. Protects Structure and Belongings: The preservation of a building's structural integrity and the protection of possessions from moisture harm are ensured by maintaining lower levels of humidity, which prevents damp-related problems.
  3. Prevents Rust and Corrosion: Where there is excessive amounts of moisture they help to prevent the corrosion and rusting of metal appliances and tools.
  4. Comfort: The decrease in indoor humidity levels can transform the environment into a cooler and more comfortable space, improving the overall living experience.
  5. Odour Reduction: Eliminates musty odours associated with high humidity levels, creating a fresher, more agreeable living environment.
  6. 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.


The most reliable recommendations for local professionals when it comes to home improvements are usually friends and family. Always get at least 2 or 3 different quotes from various companies, and if you've got any doubts you can ask to see professional membership certificates and qualifications, before hiring any damp proofing services.

Look for qualifications and membership from trade bodies such as the Property Care Association or the DPA (Damp Proofing Association), or contractors holding the CSTDB (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 the necessary working experience to perform a first class damp proof service, if they are members of the DPA or PCA. Such professional memberships also means there are guarantees for any remedial work carried out.

Dehumidifier Installation Finchley

If you want to keep indoor air quality healthy and comfortable, especially in places with high levels of humidity, dehumidifiers are indispensable. Proper installation is paramount to ensure the unit performs at its best and lasts longer.

Dehumidifier Installation Finchley

Before installing a dehumidifier, it's important to select a suitable location that is free from obstructions and has a power socket nearby. Placing the unit on a flat surface and away from furniture and walls is essential to maintain sufficient air circulation.

Correctly setting up the drainage system next is vital to prevent overflow or water damage. This may involve connecting the dehumidifier to a drain or attaching a hose to the unit. To ensure the dehumidifier operates effectively, it's important to perform routine maintenance such as replacing the filter and cleaning.

The size of the dehumidifier concerning the room or space it will be installed in should be taken into account. The efficient removal of moisture depends on using the correct size of dehumidifier, as a unit that is too small will be ineffective, while a unit that is too large can lead to energy wastage and excessive dryness. Consulting the maker's instructions or seeking professional help is recommended to ensure a safe and successful dehumidifier installation. Reduced moisture-related issues, improved indoor air quality, and enhanced overall comfort can be achieved in homes or businesses through proper dehumidifier installation and servicing.

Condensation Control Finchley

Vital for maintaining a healthy and pleasant indoor environment is the control of condensation. Through the interaction of warm, moisture-laden air with colder surfaces, condensation occurs, resulting in the formation of water droplets. The consequences of uncontrolled condensation include mould growth, damage to building materials, and a decline in indoor air quality.

Condensation Control Finchley

To control condensation, adequate ventilation is essential to regulate humidity levels and promote the circulation of air. The use of insulation and double-glazed windows assists in reducing differences in temperature and minimising condensation. By managing condensation effectively, you can create a more pleasant working or living environment and avoid potential problems.

Additionally, using double-glazed windows and insulation can help reduce temperature differentials and minimise condensation. Warm, moist air cannot come into direct contact with cold surfaces because of insulation, which acts as a thermal barrier. When the temperature difference is reduced, condensation is less likely to form on surfaces like walls, ceilings and windows. Double-glazing is effective at maintaining a consistent inside temperature and curbing condensation, thanks to its 2 panes of glass with an insulating layer in between.

Another approach to effective condensation control involves addressing moisture sources directly. Moisture is released into the air by activities like showering, drying clothes indoors and cooking. Adequate ventilation and exhaust fans in kitchens and bathrooms can help to prevent an excessive build-up of humidity. In addition, dehumidifiers can help maintain optimum indoor humidity levels in areas prone to high moisture content.

Effective condensation management can help you create a more comfortable working or living environment, free from potential issues. A controlled indoor environment not only protects the structural integrity of buildings but also ensures the well-being and health of occupants. Frequent maintenance checks, such as checking seals around doors and windows for gaps, can help you identify and address potential condensation problems. By providing even more effective ways to ensure a comfortable and healthy indoor environment, new condensation control strategies and techniques emerging from advances in building science and indoor air quality knowledge. To sum up, the implementation of proper insulation, ventilation, moisture source management, and cutting-edge technologies are all vital components of a well-rounded condensation control strategy.
