Common external issues like: broken roof tiles, defective gutters or drainpipes, unsound brickwork and blocked cavity walls, can all be principal causes of penetrating damp in a property. Inside a building, it can be triggered by leaky or burst water pipes, cracked shower trays and overflowing bathtubs or basins. If left unchecked, flaking or bubbling paintwork, broken or blistering plaster and damp, dark patches on walls, will be the noticeable results of water soaking into the walls and woodwork.

If you have a leaky roof that has been neglected for some time, your roof timbers can be stricken with wet rot. This could prove very pricey, because in the worst case scenario the structural integrity of your roof timbers could be compromised, with the result that you'll need an entire new roof. If a black fungus starts to appear on your woodwork and the timber in your roof feels "spongy" to the touch, you may have an issue with wet rot. In the event that you identify any of these wet rot symptoms, prompt attention is required to forestall further deterioration and the potential expense of a roof replacement.

Some elementary measures can help in preventing this, such as: examining piping for leaks, cleaning your roof & guttering and checking for leaks and repointing dodgy brickwork. A certified Westminster damp proof specialist will check all these areas in order to help avoid any further complications, as part of resolving your damp issues.


Condensation Damp Westminster UK (020)

Among the most common causes of damp is condensation, and lots of houses in Westminster suffer from this. When a cool surface makes contact with warm, moist air, water collects as droplets upon that surface. If there is not adequate ventilation in areas of high humidity, such as kitchens, boiler rooms and bathrooms, condensation can frequently result.

Simple solutions to reduce condensation involve wiping away any droplets as they form and making sure that you've got adequate ventilation in the main problem areas. This may require the installation or upgrade of extractor fans, air bricks and cooker hoods to help remove the humid air to the outside of the building.

By carrying out an exhaustive damp proofing survey, a reliable Westminster company will find any spots where moist air is sucked in from the outside, simply contributing to the issue. It's vital that airflow and circulation is regulated effectively, in order to control condensation problems, and you can obtain advice and information on this from a damp proofing specialist.

Damp Proofing Quotes in Westminster Greater London


Houses built since 1875 in the UK have required a damp proof course or membrane to be installed as standard. If your home was built before this period it's perfectly possible you might not have one installed. It's possible that your damp proof course or damp proof membrane might have been damaged somehow if you are experiencing rising damp issues in a house built after this year.

It can be difficult to identify rising damp, but some giveaway signs are; "tide marks" on walls, white powdery deposits being found on floor surfaces or forming on walls and crumbling or rotten skirtings. Whilst the existence of these is not conclusive, they're all indications of rising damp.

Rising Damp Westminster Greater London

Remedying rising damp problems can be as easy as checking your property's outside walls to see if you can see a damp course. For satisfactory protection it must be 150mm above ground level. If you discover this space doesn't exist, you could dig away the earth to increase it, or if this approach isn't possible, a higher DPM (damp proof membrane) will need to be installed.

If this isn't the root cause of the problem and your damp proof course is correct, there could be more problematic issues to resolve caused by the dampness coming up from the ground beneath, through your flooring, and into the walls of your home.

Westminster damp proofing experts will quickly be able to establish the causes of your rising damp issues, and using a range of techniques will soon resolve the problem. If you've got an older home with no damp proof membrane or one that's damaged over a substantial area, a damp proof cream can be carefully injected into your external walls. This involves drilling holes at evenly spaced intervals along the brickwork and the special cream injected with a nozzle to plug the spaces behind the brickwork down to below ground level.

In situations where damp proofing cream isn't a satisfactory remedy, or where your damp course membrane is extensively damaged, putting in a brand new damp proof course may be neccessary. Unfortunately this is taking repair work to the extreme, however it could be the only solution to your rising damp.

Damp Proofers Westminster (SW1)

For minimal areas of membrane damage, another possible remedy would be to coat with a waterproof (bitumen based) latex emulsion. Wood flooring, carpets or tiles must be lifted before any work is undertaken, since it's applied beneath your floor coverings. In cellars this is an especially efficacious treatment, and will form a part of the "tanking" procedure which is used to make rooms watertight. For further protection in those trouble spots, your Westminster damp proof expert might recommend the application of building paper (a foil backed specialist membrane) before the bitumen paint has dried completely.

Tanking: The "tanking" technique specifically renders cellars, basements and subterranean areas watertight by applying a unique waterproof paint to bare surfaces. Prior to this, it's necessary to strip away all plaster and wall coverings to ensure the paint adheres directly to the walls and floors' foundational layers, forming a moisture-resistant barrier. After application, the paint requires adequate drying time before any replastering or decorative work begins. Tanking, an extensive process that involves treating the entire lower area of a building, should be carefully considered. Consulting multiple damp proofing experts is recommended to assess if tanking is the most suitable approach for your rising damp issues, as there might be other less intrusive yet effective options.


To help with issues with condensation, you could try using dehumidifiers, which for removing moisture from the air, are fairly efficient. The fact that they only mask the cause of the damp and don't cure it, is the disadvantage with dehumidifier use. To obtain the best advice if you're suffering from mould or damp in any area of your property, you should get in touch with an experienced damp proofing company in Westminster.

The Benefits of Using Dehumidifiers

Below are just some of the benefits of using dehumidifiers:

  1. Overall Comfort: Creating a cooler and more comfortable indoor setting by reducing humidity levels can significantly better the living standards of occupants.
  2. Prevents Corrosion and Rust: Helps protect metal tools and appliances from rusting and corroding due to excess moisture.
  3. Odour Reduction: By reducing high levels of humidity, it eradicates musty scents, thereby fostering a fresher and more enjoyable living atmosphere.
  4. Energy Efficiency: Some dehumidifiers contribute to the efficiency of heating systems by ensuring air is drier and thus more readily heated, which can lead to potential savings on the use of energy.
  5. Health Improvements: By diminishing the levels of humidity, dehumidifiers play a crucial role in curtailing the spread of dust mites and mould, frequent triggers of respiratory conditions and aggravators of allergy and asthma symptoms.
  6. Protects Belongings and Property Structure: Moisture damage to possessions is prevented and the structural soundness of the premises is protected by ensuring humidity levels remain low to avoid damp-related problems.


As with just about any home improvement project, the most trustworthy recommendations for a professional come from neighbours and friends. Where possible you should try to acquire at least three different estimates from a range of companies, and before signing up to any specific damp proofing providers, you should ask to look at qualifications and professional memberships, as a verification of their trustworthiness.

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

You can be certain that your damp proofing specialist is properly qualified and has the required experience to provide a first class damp proof service, if they've got membership of either the PCA or DPA. Furthermore, it offers guarantees on any work completed by one of their members.

Dehumidifier Installation

Dehumidifiers play a vital role in ensuring comfortable and healthy indoor air quality, particularly in regions with high levels of humidity. For the unit to perform optimally and last long, proper installation is of utmost importance.

Dehumidifier Installation Westminster

Before installing a dehumidifier, one must carefully select an obstruction-free location with a power socket nearby. The unit should be placed on a flat surface and away from furniture and walls to allow adequate air circulation.

Next, the drainage system must be set up correctly to prevent water damage or overflow. It could require attaching a hose to the unit or connecting the dehumidifier to a drain. For the dehumidifier to operate effectively, routine maintenance such as cleaning or replacing the filter is crucial.

The dehumidifier's size concerning the space or room it will be installed in is worth considering. To guarantee a safe and successful dehumidifier installation, it's best to consult the maker's instructions or seek the assistance of a professional. Proper installation and servicing of a dehumidifier can significantly mitigate moisture-related problems, improve indoor air quality, and enhance overall comfort in homes or businesses.

DPC Replacement Westminster

Preserving the aesthetic appeal and structural integrity of your property in Westminster necessitates timely Damp Proof Course (DPC) replacement. The existing DPC, over time, can deteriorate due to wear and tear, potentially leading to rising damp. Vigilant observation for signs such as damp spots, deteriorating brickwork or crumbling plaster is crucial. DPC replacement involves removing the old, ineffective barrier and installing a new, robust one. This process typically requires professional expertise, as it demands precision and thoroughness to ensure a reliable seal against moisture intrusion.

The choice of materials for the new DPC can vary depending on the specific needs of the property. Traditional methods like slate or bitumen have a long history of success in combating rising damp, while more modern options like chemical injections offer a less disruptive approach. Effective DPC replacement not only prevents further moisture-related damage but also contributes to a healthy indoor environment and safeguards the value of your Westminster property. Routine inspections and timely DPC replacement are essential for ensuring your property remains structurally sound and dry. (85222 DPC Replacement Westminster)
