  • Penetrating Damp

  • Condensation

  • Rising Damp


The next article describes the causes of such damp issues in Hendon, and the different techniques for preventing and resolving them.


Penetrating damp can be the result of a variety of external factors for instance: damaged drainpipes or gutters, blocked cavity walls, broken or loose roof tiles and damaged or porous brickwork. In the interior of your house it can be caused by overflowing basins or bathtubs, burst or leaky water pipes and damaged shower trays. Visible signs like broken or blistering plaster, flaking paintwork and dark, damp patches on walls, all point to the fact that these issues have been left unchecked.

If left untreated over a long period of time, a leaking roof can cause wet rot in your roof timbers. This could prove very expensive, because if worse comes to worse the structural integrity of your roof timbers could be compromised, meaning that you'll need a whole new roof. There are several indicators of wet rot which are not difficult to spot, the main ones being; a "spongy" feel to the timber, the presence of black fungus on woodwork and a musty smell of rotting wood. For the sake of avoiding further structural damage and the potential need for costly roof replacement, it is essential to address any signs of wet rot without delay.

The means of prevention can be quite basic, for instance cleaning your roof & guttering and checking for leaks, repointing dodgy brickwork and inspecting pipes for leaks. As an integral part of fixing your damp issues, a competent Hendon damp proofing service provider will check all of these areas, in order to help prevent any further issues.


Condensation Damp Hendon UK (020)

Condensation is very easy to identify and a common form of damp within many houses in Hendon. Water collects as small droplets on a cold surface, when moist, warm air makes contact with it. In areas with high humidity, as in: boiler rooms, kitchens and bathrooms, condensation forms because of poor ventilation.

To avoid condensation issues, easy solutions include ensuring you've got adequate ventilation in the affected areas, and wiping away any droplets of water the moment they form. You can minimise the level of humid air that's present in your home by upgrading or installing extractors, air bricks and cooker hoods.

An in-depth damp proofing survey by a reliable Hendon company might also find areas which exacerbate the situation by drawing in moist air from outside. In order to control condensation problems, it's essential that circulation and airflow in the home is effectively regulated, and by talking to an expert in this field, you can get information and advice for fixing these issues.

Damp Proofing Quotes in Hendon Greater London


Since 1875, a damp proof course or membrane has been compulsory in all houses built in the UK. You might not have a damp course on your home in Hendon if it was constructed prior to this period. If your house was constructed after this year, but you are still suffering with rising damp, it could be that your damp proof membrane has been impaired.

If you believe that you may have rising damp in your home, white powdery deposits being found on floor surfaces or forming on walls, crumbling or rotten skirting boards and tide marks on walls, are fair indications that you may be right. If you see or think that you may have any of these, it is possible that you've got a problem with rising damp.

Rising Damp Hendon Greater London

Solving rising damp issues can be as easy as checking your home's outside walls and seeing if you can see a damp course. It ought to be 150mm (around six inches) above ground level for adequate protection. You can dig away the surrounding soil to create this gap if it is currently not sufficient, or you can put in a damp course higher up if the first option isn't possible.

You might have more problematic issues if you find that your damp proof membrane (DPM) is okay, and it may be that the damp is rising from the ground, through your flooring, and into your home's walls, which will be an even more worrying situation.

Hendon damp proofing professionals will swiftly be able to determine the root cause of your rising damp, and employing a number of techniques will quickly resolve the problem. Older houses which either don't have a DPM at all, or have a compromised one that's damaged over an extensive area, can be treated with a damp proofing injection cream. Evenly spaced holes are drilled at intervals along the mortar course, and a nozzle is used to inject the special cream, which then penetrates into the surrounding brickwork before curing to create an effective, horizontal water-repelling barrier.

If the damage to your DPM is too critical, or if damp proofing injection cream isn't a suitable treatment, you might have to put in a brand new damp proof course. Though this is of course a pretty drastic plan of action, it might be the only method to resolve your damp problems effectively.

For smaller areas of damage, another possible option would be to coat with a bitumen based, waterproof latex emulsion. This will be applied under your floor coverings, so carpeting, tiles and laminate flooring will have to be lifted prior to work being done. This is particularly effectual in cellar areas as an integral part of the "tanking" process to create a room that's watertight. Your Hendon damp proofing expert might recommend laying building paper (a specialist foil backed membrane) before the bitumen coating has dried completely, added protection in those problem areas.

Tanking: "Tanking" is a specific waterproofing technique for basements, cellars and other below-ground areas, which involves the application of a unique watertight paint on exposed surfaces. For effective application, it's essential to remove all plaster and wall coverings, allowing the paint to be applied directly to the wall and floor bases, thus creating an indispensable barrier against moisture. Ensuring the paint dries completely before any further plastering or decoration is crucial. Given that tanking involves treating an entire property's lower level, it's wise to consult with a range of damp proofing experts to determine if it's the most suitable solution for your damp problems. Considering tanking's extensive and disruptive nature, it's also important to explore other, less invasive, yet potentially effective options.


Dehumidifiers are a highly effective way to remove moisture from the air, hence for issues with condensation they can help quite a bit. The main problem with dehumidifiers in attempting to reduce dampness is that they only hide the cause of the damp, don't cure it. To obtain the best advice if you're suffering from damp in any part of your property, you should speak to a certified damp proofing specialist in Hendon.

Benefits of Using Dehumidifiers

Below, you'll find a list of notable advantages that come with the application of dehumidifiers:

  1. Energy Efficiency: Some dehumidifiers enhance the efficiency of heating systems by drying the air, which simplifies the heating process and could lead to significant savings on energy use.
  2. Health Improvements: The use of dehumidifiers to reduce ambient humidity levels is instrumental in suppressing the proliferation of dust mites and mould, allergens that commonly cause respiratory complications and exacerbate symptoms of allergies and asthma.
  3. Overall Comfort: The decrease in indoor humidity levels contributes to a more comfortable and cooler environment, improving occupants' living conditions.
  4. Protects Belongings and Property Structure: Lower levels of humidity protect the structural integrity of the building by preventing damp-related issues and protect belongings from moisture damage.
  5. Odour Reduction: A more pleasant and fresher living environment is attained by dispelling musty odours associated with elevated levels of humidity.

Dehumidifier Installation

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

It's important to ensure that the location selected for dehumidifier installation is free from obstructions and has a nearby power point. The unit must be positioned on a flat surface and kept away from furniture and walls to ensure proper air circulation.

Setting up the drainage system correctly is the next step to prevent water damage or overflow. Attaching a hose to the unit or connecting the dehumidifier to a drain may be part of the process. Regular maintenance, such as replacing the filter and cleaning, is also important for the effective operation of the unit.

Taking into consideration the dehumidifier's size concerning the space or room it will be installed in is crucial to ensure optimal performance. A dehumidifier that's too small will not effectively remove moisture, while a unit that is too large can lead to energy wastage and excessive dryness. To ensure a safe and successful dehumidifier installation, it's advisable to consult the maker's instructions or seek professional assistance. 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 maintenance.

Cementitious Tanking Hendon

In cellars and basements, cementitious tanking is a popular method of preventing moisture penetration. To the floors and walls of the area, a cement-based waterproofing system is applied as part of this process. With the tanking material, one has the option of mixing it in-situ or purchasing it pre-manufactured, with a range of grades suitable for various substrates.

Cementitious Tanking Hendon

Cementitious tanking can provide a long-lasting and durable barrier against water penetration, but proper application is vital to achieve the best possible outcome. The surface must be clean, dry, and free from any loose material or contaminants before application to ensure optimal results.

Professional installation by a certified damp proofing specialist is the recommended course of action to achieve a long-lasting and high-quality result. Achieving proper installation of cementitious tanking can provide a dependable and effective solution for waterproofing basements and underground spaces in Hendon. The efficiency of the system can be maintained and moisture ingress prevented by regularly inspecting it and addressing any damage or wear.

PIV (Positive Input Ventilation)

The ideal solution to damp problems within your house in Hendon could be Positive Input Ventilation (PIV). PIV can aid in reducing humidity levels, which can alleviate mould and damp in your dwelling or condensation on your windows. To achieve this, a constant flow of fresh air is supplied. The constant replacement and refresh of air inside your house has been shown to reduce pollutants and odours, decrease dust mite allergens, and enhance air quality, ultimately benefiting asthma and allergy sufferers in their day-to-day lives. When considering PIV systems, it is important to note that they work best when installed in a loft space and require the house to be relatively airtight. When gaps exist in doors or windows, fresh air can escape while contaminated air enters, since air follows the path of least resistance, similar to water.

Condensation Control

Control of condensation is crucial for maintaining a healthy and comfortable indoor environment. Water droplets form when warm, moisture-laden air comes into contact with cooler surfaces, causing condensation. Uncontrolled condensation can lead to damaged building materials, the growth of mould, and a decline in indoor air quality.

Condensation Control Hendon

To control condensation, proper ventilation is essential to regulate the amount of humidity and promote air circulation. Insulation and double-glazed windows can be employed to help minimise condensation and reduce temperature differentials. Achieving effective condensation management allows for the prevention of potential issues and the creation of a more pleasant living or working environment.

In addition to reducing temperature differentials and minimising condensation, double-glazed windows and insulation can also help. Cold surfaces are prevented from coming into direct contact with moist, warm air by 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 ceilings, windows and walls. Double-glazing, featuring two panes of glass with an insulating layer in between, is effective at maintaining an even interior temperature, further inhibiting condensation.

Another effective condensation control approach is to address the sources of moisture directly. Moisture is released into the air by activities like showering, drying clothes indoors and cooking. To prevent excessive humidity buildup, use exhaust fans and ensure adequate ventilation in kitchens and bathrooms. Dehumidifiers can be used to help maintain optimal indoor humidity levels in areas prone to high moisture content.

A more comfortable working or living environment can be created by effectively managing condensation and preventing potential issues. The health and well-being of occupants, as well as the structural integrity of buildings, can be ensured by controlling the interior environment. Identifying areas where condensation might occur can be aided by regular maintenance checks, such as inspecting seals around windows and doors for gaps. As indoor air quality and building science knowledge advances, new condensation control strategies and techniques emerge, offering even more effective ways to ensure a comfortable and healthy indoor environment. To summarise, proper insulation, moisture source management, ventilation, and cutting-edge technologies are all essential components of a well-rounded condensation control strategy.
