  • Penetrating Damp

  • Condensation

  • Rising Damp


In paragraphs that follow, we'll take a look at what causes such damp problems, and ways that you can go about solving them, and preventing them from occurring in the first place.


Problems like loose or broken roof tiles, porous brickwork, defective guttering or downpipes and cavity wall problems are external factors of penetrating damp. Inside your dwelling, it can also be a result of cracked shower trays, burst or dripping pipework and overflowing bathtubs or basins. If left to carry on leaking these factors allow water to seep into walls and woodwork, which in time create blistering or broken plaster, flaking or bubbling paintwork and damp, dark patches on walls.

If you've got a leaking roof and it has been left untreated for a while, it can cause wet rot to develop in your roof timbers. If worse comes to worse, you may even need to replace the entire roof, since wet rot can cause your roof timbers to become structurally unsound and dangerous. There are several indicators of wet rot that aren't hard to spot, the principle ones being; a "spongy" feel to the timber, a musty smell of rotten wood and the presence of black fungus on woodwork. It is essential to act promptly to prevent further structural damage and the potential need for expensive roof replacement, should you observe any signs of wet rot.

The means of prevention can be quite basic, for instance cleaning your roof & guttering and checking for leaks, repointing unsound brickwork and inspecting piping for leaks. An experienced damp proofer in Hampstead will check these areas in order to help avoid any further problems, as an integral part of solving your issues with dampness.


Condensation Damp Hampstead UK (020)

Numerous homes in Hampstead have problems with condensation, and this is among the most common factors that cause damp. Water collects as droplets on a cold surface, when moist, warm air comes into contact with it. Inadequate ventilation in places with high humidity, such as in bathrooms, boiler rooms and kitchens, is the most frequent explanation for condensation.

To avoid condensation problems, simple solutions include making sure that you have adequate ventilation in the affected areas, and wiping away any droplets of water as soon as they form. Redirecting damp air outside of your home in Hampstead, by updating or fitting air bricks, extractors and cooker hoods, will help you to resolve this annoying problem.

With some properties damp air is drawn in from the outside, simply making matters even worse. And the best way to establish the main things that bring about the problem, is to have a detailed damp proofing survey carried out by a trusted Hampstead damp proofing specialist. Airflow must be regulated properly to successfully control condensation, and a competent damp proofing specialist will offer advice and solutions on this topic.

Damp Proofing Quotes in Hampstead Greater London


A damp proof course has been fitted as standard on homes built in the UK since 1875. It is perfectly possible that you may not have one installed if your house in Hampstead was built before this time. If your property was constructed after this year, but you're still experiencing rising damp issues, it could be that your damp course or damp proof membrane has been compromised.

Rising damp can be difficult to distinguish, but some areas to look for are; "tide marks" on walls, a white powdery deposit being discovered on floor surfaces or forming on walls and crumbling or rotten skirting boards. It is feasible that you could have a rising damp problem if you have noticed one or all of these in your home.

Rising Damp Hampstead Greater London

Just checking your home's outside walls to spot if you've got a damp proof course can be one step towards resolving your rising damp. For adequate protection it must be 150 millimetres (about 6") above ground level. If you discover that this space does not exist, you could dig the earth away to increase it, or if this process is not possible, a higher DPM will have to be put in.

If this is not the problem and your damp proof course is installed and in order, there might be more problematic issues to resolve caused by the moisture rising up from the ground, through your floor, and into the walls of your property.

Hampstead damp proofing professionals will swiftly be able to determine the root cause of your rising damp issues, and using a number of techniques will quickly solve the problem. A damp proofing cream (such as Dryzone or Permaguard) can be carefully injected into your wall if you have an older house with no damp proof membrane, or it is damaged over an extensive area. This special cream is injected with a nozzle into holes drilled along the mortar joint, and before the cream can set it turns into liquid and soaks into the surrounding brickwork forming a barrier that is repellent to water.

If the damage to your DPM is too extensive, or if damp proofing cream injection is not a suitable treatment, you may have to install a brand new damp proof course. Though this is of course a pretty extreme approach, it could be the best way to solve your damp issues effectively.

Yet another option for less severe areas of damage could include painting with a bitumen based, waterproof latex emulsion coating. This has to be applied underneath your current floor coverings, so wooden flooring, tiles and carpeting will have to be lifted prior to work being done. Also used as part of the "tanking" procedure to make a room watertight, this is a particularly effective solution in cellar areas. Before the bitumen paint has dried completely, your Hampstead damp proof expert may recommend laying building paper (a specialist foil backed membrane), for added protection.

Tanking: The technique known as "tanking" waterproofs basements 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.


Dehumidifiers are an efficient way to remove moisture from the air, so for condensation issues they can help quite a lot. Owing to the fact that dehumidifiers primarily hide the cause of the damp and not get rid of it, there are drawbacks to this solution. To obtain the most reliable advice if you are experiencing dampness in any area of your home, you can get in touch with a competent damp proofing company in Hampstead.

The Benefits of Using Dehumidifiers

The following points outline some significant benefits derived from the use of dehumidifiers:

  1. Energy Efficiency: Savings on energy use may result from the use of some dehumidifiers, as they make air easier to heat by reducing moisture, thereby improving heating system efficiency.
  2. Prevents Rust and Corrosion: Where there is excessive moisture they help to prevent the corrosion and rusting of metal tools and appliances.
  3. Protects Structure and Belongings: Moisture damage to possessions is prevented and the structural soundness of the building is protected by ensuring humidity levels remain low to avoid damp-related issues.
  4. Comfort: Reduced humidity levels can make the indoor environment feel cooler and more comfortable, thus improving living conditions for the occupants.
  5. Odour Reduction: By reducing high humidity levels, it eradicates musty odours, thereby fostering a fresher and more enjoyable living atmosphere.
  6. Improvements in Health: By reducing humidity levels, dehumidifiers help mitigate the growth of mould and dust mites, common allergens that can cause respiratory issues and aggravate asthma and allergies.


As with just about any project, the most trustworthy recommendations for a professional come from friends and neighbours. Always get at least 2 or 3 different quotes from a variety of companies, and if in any doubt you should ask to see professional memberships and accreditations, before hiring any damp proofing services.

Look out for technicians holding the Certificated Surveyor in Remedial Treatments or the CSTDB (Certificated Surveyor of Timber and Dampness) professional qualifications, or local companies who are members of the DPA (Damp Proofing Association) or the Property Care Association.
