  • Penetrating Damp

  • Condensation

  • Rising Damp


We'll look at these 3 significant forms of damp problems, and come up with recommendations for how to prevent them and resolve them, should they occur.


Common external factors like: cracks in brickwork, blocked cavity walls, loose or cracked roof tiles and defective drainpipes or guttering, can all be primary causes of penetrating damp in a building. In the interior of your house it can be a result of overflowing basins or baths, dripping or burst pipework and damaged shower trays. If left uncontrolled, walls and timber components can be severely affected, and the sure indicators of this will be peeling paintwork, broken or blistered plaster and dark, damp patches on walls.

You may get wet rot developing in the timbers of your roof, if you have a leaky roof, and it's been neglected for a prolonged period of time. Wet rot can't spread into brickwork, but it can mean that in a worst case scenario the timbers of your roof become structurally dangerous, necessitating a new roof. If a black fungus starts to appear on your woodwork and the roof timbers feel "spongy" to the touch, you may have the beginnings of wet rot. Dealing with the issue promptly is essential if you happen to notice any of these wet rot signs, as it can prevent further structural damage and the potential necessity of costly roof replacement.

Preventative measures can be basic, such as repointing brickwork, cleaning your roof & rain gutters and checking for leaks and inspecting water pipes for leaks. If you contact a reliable damp proofing specialist in Harrow, they'll check all of these areas, and prepare a plan for both fixing your damp problems and forestalling further episodes.


Condensation Damp Harrow UK (020)

There are many factors that cause dampness, but condensation is one of the most common and easily noticed. Small droplets of water appear on cool surfaces when moist, warm air makes contact with these surfaces. It is a problem due to poor ventilation in places where high humidity is present, i.e. kitchens, bathrooms and boiler rooms.

To reduce the impact of this there are two simple steps that you can take. You can wipe away any droplets of water the instant they arise, and you can make certain that there is good ventilation in areas that suffer from condensation. This may require the updating or installation of cooker hoods, extractor fans and air bricks to help remove the humid air outside of the building.

To find factors which bring about the problem by drawing in moist air from outside, an experienced Harrow damp proofing company will carry out an exhaustive damp proofing survey. Circulation and airflow must be properly regulated to successfully control condensation, and a knowledgeable damp proofing specialist will be able to offer advice and solutions on this question.

Damp Proofing Quotes in Harrow Greater London


Since 1875, a damp proof course has been fitted as standard in all homes constructed in the UK. You may not have a damp course installed on your property or home in Harrow if it was constructed prior to this period. If your house was constructed after this year, but you are still suffering with rising damp problems, it could be that your damp proof membrane has been impaired.

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

Rising Damp Harrow Greater London

Fixing rising damp issues can be as easy as checking your home's exterior walls to see if you can see a damp course. It should be 150 millimetres (approximately six inches) above ground level for satisfactory protection. You can dig away the surrounding soil to create this space if it's currently not enough, or you can put in a damp proof membrane (DPM) higher up if the former isn't possible.

You may have more serious issues if you find that your damp course is OK, and it might be that the damp is seeping up from the ground, through your flooring, and into your home's walls, which will be an even more troubling state of affairs.

Using a number of different techniques, damp proofing specialists in Harrow can swiftly identify and resolve rising damp issues. A damp proofing cream can be carefully injected into your walls if you have a somewhat older house with no damp proof membrane, or it is damaged over an extensive area. This involves the drilling of holes at intervals in your wall's mortar course and the special cream injected with a nozzle to fill up the spaces behind the brickwork.

If the damp proofing cream treatment is not appropriate, or the damage to your DPM is too extensive, a brand new damp proof course may need to be installed. While this sort of repair work is a pretty drastic way to solve damp problems, it may be your only real solution when all is said and done.

The application of a waterproof (bitumen based) latex emulsion, is another possible remedy for smaller areas of membrane damage. This is applied underneath your floor coverings, so laminate flooring, carpets and tiles will need to be lifted prior to work being undertaken. This is especially effective in cellars as a part of the "tanking" procedure to make a room that's watertight. For added protection in such troublesome areas, your Harrow damp proof specialist may advise laying building paper (a specialist foil backed membrane) before the bitumen coating has dried completely.

Tanking: The process of coating exposed surfaces with a waterproof paint in a cellar or below ground area is known as "tanking". Since this watertight coating needs to be applied on the bare surface of walls and floors, any plaster and wall coverings must be removed before any work can commence, and the relevant surfaces correctly prepared. When the coating has been applied and is dry, it is then the time to replaster and decorate over the top of it. This is a highly disruptive job since it must be applied to an entire basement level or ground floor of a building, and it is preferable to get more than one expert's opinion about whether this is really the only answer to your rising damp problems.


To help with condensation issues, you could try using dehumidifiers, which for lowering the moisture content of the air, are pretty efficient. The trouble with the use of dehumidifiers in seeking to stop mould and damp is that they merely mask the cause of the damp, don't get rid of it. To obtain the most reliable advice if you're suffering from damp in any area of your home, you should get in touch with an experienced damp proofing specialist in Harrow.


As with pretty much any project, the most reliable recommendations for a local professional come from friends and family. Always get at least two or three different quotes from various companies, and if you're in any doubt you should ask to see qualifications and professional memberships, before signing up for any damp proof services.

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

Membership of the PCA or DPA guarantees that your selected damp proofing specialist is suitably qualified and has acquired the required experience to carry out a first class damp proof service. Any remedial work supplied by one of their members also comes with a guarantee.

Black Mould Issues

If you're experiencing signs of black mould, you could have an issue with Stachybotrys chartarum. This fungus is highly toxic and produces a slime head called conidia. It is known as a primary cause of indoor air pollution and is also considered a health hazard. If you see indications of this form of mould in your home in Harrow, you should speak to an experienced damp proofing specialist straight away, to get the best treatment.

Black Mould Harrow

The first step in eliminating mould is to clean the area with soapy water. You should also use a disinfectant such as bleach, which can kill any mould spores. Hydrogen peroxide and white vinegar are also effective disinfectants. However, you must be very careful while using bleach, because it could burn and irritate your eyes. Also, make sure there's adequate ventilation in the area where you are working, to help clear away the fumes.

Black mould is a highly infectious fungus. It can cause life-threatening infections in folks with weak immune systems. Often, it evolves in cracks and other places where the air cannot circulate properly. Symptoms can include large warts and cauliflower-like lesions on the skin. The area may also be swollen or red. It can even affect the nails.

Dehumidifier Installation

To maintain comfortable and healthy indoor air quality, especially in high humidity spaces, dehumidifiers are a must-have appliance. To achieve the unit's optimal longevity and performance, proper installation cannot be overlooked.

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

To prevent water damage or overflow, setting up the drainage system correctly is the next essential task. This might involve connecting the dehumidifier to a drain or attaching a hose to the unit. The effective operation of the unit requires routine maintenance, such as replacing the filter and cleaning.

Enhancing the performance and benefits of a dehumidifier can be achieved by meticulously selecting its location and size. To guarantee a successful and safe dehumidifier installation, it's best to consult the manufacturer's instructions or seek professional assistance. Proper installation and maintenance of a dehumidifier can significantly improve indoor air quality, mitigate moisture-related problems, and enhance overall comfort in homes or workplaces.
