The following paragraphs describe what may cause such problems with damp in Twickenham, and the various methods of avoiding and solving them.


Penetrating damp can be caused by numerous external factors for example: blocked cavities, cracks in brickwork, defective downspouts or guttering and loose or cracked roof tiles. From within, the causes can be cracked shower trays, burst or leaking pipework and overflowing bathtubs or sinks. Obvious signs like broken or blistering plaster, flaking or bubbling paintwork and dark, damp patches on walls, all suggest that these issues have been left unresolved.

If you have a leaking roof that has been left untreated for some time, the timbers of your roof can be stricken with wet rot. Although it can't spread into the brickwork, wet rot can cause the timber in your roof to become structurally dangerous, and in the worst outcome you may even need a new roof - very costly! There are several indications of wet rot that aren't difficult to spot, the main ones being; a musty smell, a "spongy" feel to the timber and the presence of black fungus on woodwork. It is essential to swiftly deal with any signs of wet rot to prevent further structural harm and the potential need for expensive roof replacement.

The measures for prevention can be pretty basic, for example repointing brickwork, examining piping for leaks and cleaning and checking your rain gutters & roof for leaks. A professional Twickenham damp proof specialist will check all these areas in order to help avoid any future problems, as part of fixing your issues with damp.

The best way to successfully minimise condensation is to properly regulate circulation and airflow , and your local Twickenham damp proofing specialist will offer advice and guidance on how this can best be accomplished.

Damp Proofing Quotes in Twickenham Greater London


A damp proof course has been compulsory on houses constructed in Great Britain since 1875. If your home or property was built before this period it's conceivable you might not have this installed. If you are experiencing rising damp in a house built after this date it is possible your damp proof membrane or course has been damaged in some way.

Although notoriously difficult to identify, crumbling or rotten skirting boards, a white powdery deposit being found on floor surfaces or forming on walls and "tide marks" on walls, are all giveaway clues that you might have rising damp. If you notice or think you might have any of these issues, it is possible that you have a rising damp problem.

Rising Damp Twickenham Greater London

Just checking your home's exterior walls to spot if you've got a damp course can be the first step towards resolving your rising damp. It ought to be 150mm (about six inches) above ground level for adequate protection. You could dig the surrounding ground away to create this space if it's currently not enough, or you can install a DPM higher up if the first option is not possible.

You could have more problematic issues if you find that your damp proof membrane (DPM) is okay, and it could be that the moisture is creeping up from the ground, through your flooring, and into the walls, which can be an even more worrying situation.

Using a number of methods, damp proofing specialists in Twickenham will quickly identify and eliminate rising damp issues. If you have an older house with no damp proof membrane or one that is damaged over a wide area, a damp proofing cream can be carefully injected into your external walls. Holes are drilled at intervals in the mortar course, and a nozzle is used to inject the special cream, which then diffuses before curing to create an effective waterproof barrier.

In situations where damp proofing cream isn't a suitable solution, or where your membrane is extensively damaged, installing a complete new damp proof course could be neccessary. This is the most extreme of repair works, but it might be the only resolution to your rising damp.

Another possible remedy for minimal areas of membrane damage may include painting on a layer a waterproof (bitumen based) latex emulsion. Because this is applied under your existing floor coverings, tiles, wood flooring and carpeting will need to be lifted and removed before this procedure can commence. This is particularly effectual in cellar areas as part of the tanking procedure to make a room that's watertight. Your Twickenham damp proofing expert might suggest laying building paper (a special foil backed membrane) before the bitumen paint has dried completely, further protection in such troublesome areas.

Tanking: The technique known as "tanking" waterproofs cellars or subterranean areas by applying a special watertight paint to bare surfaces. Before this can be done, it's necessary to strip away all plaster and wall coverings for the coating to effectively adhere to the wall and floor bases. This crucial step forms a moisture-resistant barrier. After application, the coating must be completely dried before continuing with replastering and decorating. Tanking treats the entire lower level of a property and can be quite extensive, so consulting multiple damp proofing experts is recommended to assess if it's the optimal approach for your rising damp problems. Other, less invasive options might be just as effective and should be considered due to the significant nature of tanking.


Condensation problems can definitely be improved through the use of dehumidifiers, which are a highly efficacious way to remove moisture from the air. Owing to the fact that dehumidifiers only mask the cause of the damp and don't cure it, there are issues with this solution. To get the most reliable advice if you are suffering with mould or damp in any part of your home, you can get in touch with a professional damp proofing specialist in Twickenham.

Dehumidifier Installation

The installation of dehumidifiers is essential to maintain a healthy and comfortable indoor air quality, particularly in spaces with high levels of humidity. Without proper installation, the unit's performance and longevity will be compromised.

Dehumidifier Installation Twickenham

It's important to ensure that the location selected for dehumidifier installation is free from obstruction and has a nearby power point. To facilitate sufficient air circulation, it's crucial to place the unit on a flat surface and keep it away from furniture and walls.

The next vital step is to ensure the drainage system is set up properly to prevent overflow or water damage. Attaching a hose to the unit or connecting the dehumidifier to a drain may be part of the process. For the dehumidifier to operate effectively, regular maintenance such as replacing the filter and cleaning is crucial.

To ensure proper installation, it's important to take into account the dehumidifier's size concerning the room or space it will be installed in. A dehumidifier that is too small won't remove moisture effectively, whereas a unit that is too big can cause energy waste and excessive dryness. The performance and benefits of a dehumidifier can be greatly improved by taking the time to select the right size and location. Seeking the help of a professional or referring to the maker's instructions is recommended to ensure a successful and safe dehumidifier installation. Indoor air quality can be improved, moisture-related problems reduced, and overall comfort enhanced in homes or businesses through proper dehumidifier installation and maintenance.

Available in a range of grades suitable for various substrates, the tanking material can be mixed in-situ or pre-manufactured.

Cementitious Tanking Twickenham

Proper installation of cementitious tanking can offer a reliable and effective solution for waterproofing basements and cellars in Twickenham.

Woodworm Treatment and Prevention Twickenham

Woodworm is a common problem in Twickenham, particularly in buildings that are older, where the larvae of certain types of beetles eat away at the wood. This can cause significant damage over the years, making the structure unsafe and unsound. Woodworm treatment is essential to prevent any further damage to the building.

Identifying the type of beetle responsible for a woodworm infestation is the first step in successfully treating the problem. Depending on the specific species, different treatments might be necessary to eradicate the pests and prevent further damage. Seeking the assistance of a knowledgeable woodworm professional is highly recommended, as they can perform an in-depth assessment of the situation and offer expert advice on the most suitable methods of treatment to address the infestation and safeguard 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 deeply penetrate the wood and eliminate the larvae. This approach is most effective for minor infestations, and a professional can determine whether this is the most suitable option. For more extreme infestations, fumigation may be necessary. This involves sealing the affected area and releasing a gas into the space to kill off the larvae. Fumigation is a more invasive treatment, however it is often the best option for larger infestations.

So as to prevent woodworm infestations in the future, it is important to ensure that the environment isn't conducive to their growth. This can be achieved through regulating humidity levels, good ventilation, and treating any existing woodworm as soon as it is identified.

To summarise, woodworm prevention and treatment require a hands-on approach. By identifying and addressing any warning signs of an infestation early, and taking measures to prevent future infestations, householders can protect their buildings and preserve their structural integrity.

PIV (Positive Input Ventilation) Twickenham

For alleviating damp problems within your home or business premises in Twickenham, Positive Input Ventilation (PIV) might be the ideal solution. PIV can help in reducing humidity, which can alleviate damp and mould in your dwelling, or condensation on your windows. It maintains this by constantly supplying a flow of fresh air. The constant refresh and replacement of air inside your home has been shown to reduce pollutants and odours, decrease dust mite allergens, and improve air quality, ultimately benefiting allergy and asthma sufferers in their day-to-day lives. Installing PIV systems in an attic and ensuring that your home is fairly airtight are important considerations when opting for this solution. Air, like water, takes the path of least resistance, and any spaces and gaps in doors or windows will allow the fresh air out, while bringing possible contaminated air in from the outside.

Black Mould Issues

Black Mould Twickenham

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

Another idea is the use of a water and baking soda paste to treat the mould. This solution has a pH of 2.5, making it an effective antibacterial. Hydrogen peroxide is another treatment that can be beneficial for getting rid of black mould. It is a natural, 3 in 1 solution that's safe to use, particularly on porous surfaces.

DPC Replacement Twickenham

Preserving the structural integrity and visual appeal of your Twickenham property necessitates the timely replacement of a deteriorating Damp Proof Course (DPC). As time elapses, the existing DPC may become compromised, potentially leading to the emergence of rising damp. Vigilant observation for signs such as damp spots, deteriorating brickwork or crumbling plaster is essential. DPC replacement involves removing the old, ineffective barrier and installing a new, sturdy one. This process typically demands professional expertise, as it necessitates care and precision to guarantee a dependable barrier against moisture infiltration.

Material selection for the replacement of the Damp Proof Course offers a wide range of possibilities, including traditional materials like bitumen or slate, as well as contemporary options such as chemical injections. A well-performed DPC replacement not only halts the progress of moisture-related damage but also contributes to maintaining a healthy indoor environment and safeguarding the value of your Twickenham home.
