If you have problems with dampness in your dwelling in Dorchester, there are three probable triggers:

Damp Proofing Dorchester Dorset (DT1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


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


Issues like damaged or porous brickwork, loose or broken roof tiles, blocked cavity walls and defective downspouts or gutters are external factors of penetrating damp. Internal reasons behind penetrating damp might be overflowing basins or bathtubs, cracked shower trays and burst or dripping pipework. If left unresolved, woodwork and walls can be seriously affected, and the sure signs of this will be damp, dark patches on walls, peeling paintwork and broken or blistering plaster.

If you've got a leaking roof that's been left untreated for some time, the timbers of your roof can be stricken with wet rot. In the worst case scenario, you might even need to rebuild the whole roof, because wet rot can cause your roof timbers to become dangerous and structurally unsound. If black fungus appears on any woodwork and the timber in your roof feels "spongy" to touch, you might have a case of wet rot. When you spot any of these signs of wet rot, dealing with the issue immediately is essential to prevent further structural damage and the potential need for expensive roof replacement.

Some simple maintenance can help prevent this, such as: repointing brickwork, examining pipework for leaks and cleaning and checking your roof & gutters for leaks. As an integral part of resolving your damp problems, a knowledgeable Dorchester damp proofing service provider will check these things, so as to help reduce the chances of any further problems.


Condensation Damp Dorchester UK (01305)

Condensation is super easy to identify and a common form of damp in many homes in Dorchester. Water collects as droplets on a cold surface, when warm, moist air makes contact with it. Where high humidity is present, as in kitchens, boiler rooms and bathrooms, condensation is often caused by poor ventilation.

Wiping away any droplets of water that form, and making certain you have enough ventilation in the worst affected areas, are among the simplest answers to such issues. This might call for the installation or upgrade of extractor fans, cooker hoods and air bricks to help remove the damp air to the outside of your property.

The best way to identify the main circumstances that give rise to the situation, is to get an in-depth damp proofing survey carried out by a professional Dorchester damp proofing specialist. Occasionally moist air can be drawn in from outside, simply making matters even worse. Airflow and circulation must be properly regulated to adequately minimise condensation, and a professional damp proofing technician will be able to offer advice and solutions on this question.

Damp Proofing Quotes in Dorchester Dorset


Houses built since 1875 in the UK have been required to have a damp proof course to be installed as standard. It's perfectly possible that you might not have one fitted if your home in Dorchester was built in the years before this. If your property was constructed after this date, but you're still experiencing rising damp issues, it could be that your damp proof course or membrane has been compromised.

Rising damp can be tricky to identify, but some things to watch out for are; a white powdery deposit being found on floor surfaces or forming on walls, rotten or crumbling skirtings and tide marks on walls. Although the existence of one or more of these is not conclusive, they are all indications of rising damp issues.

Rising Damp Dorchester Dorset

Solving rising damp issues can be as easy as checking your home's external walls and seeing if you can spot a damp proof course. For adequate protection it needs to be 150 millimetres (approximately 6 inches) above the level of the ground. If this isn't the situation you might be able to dig the ground away to generate this space, or if this is not plausible, you can put in a higher damp course.

If this isn't the problem and your damp proof membrane is installed and in order, there may be more challenging issues to deal with caused by the dampness coming up from the ground beneath, through your floors, and into the walls of your home.

Damp proofing technicians in Dorchester will quickly detect and eliminate rising damp issues using a number of techniques. Older homes which either have no DPM, or have a compromised one that's damaged over an extensive area, can be treated with a damp proofing injection cream such as Dryzone. This special cream is injected with a nozzle into evenly spaced holes drilled along the mortar course, and before the cream can cure it diffuses into the surrounding brickwork creating a barrier that is repellent to water.

If the damp proof cream treatment is not appropriate, or the damage to your DPM is too extensive, a new damp proof course may need to be installed. Although this is obviously a fairly drastic approach, it might be the best way to resolve your damp problems in an effective way.

Another possible remedy for smaller areas of membrane damage might include painting on a layer a waterproof (bitumen based) latex emulsion coating. Wood flooring, tiles or carpets will have to be lifted before any work can be undertaken, because it is applied underneath your current floor coverings. Also used as an integral part of the tanking procedure to make a room watertight, this is an especially efficacious treatment in cellar areas. Before the bitumen coating has completely dried out, your Dorchester damp proofing expert may advise applying building paper (a foil backed specialist membrane), for extra protection.

Tanking: Tanking a room, like a basement or cellar, is a process of coating any exposed surfaces in a waterproof paint. This has to be applied on the base surface of walls and floors, so any wall covering and plaster must be removed and the pertinent surfaces prepared properly before the commencement of any work. When the paint has been put on and is dry, it's then the time to replaster and decorate over the top of it. Since it needs to be applied to a whole ground floor or basement level of a building, this is a very disruptive process. Therefore, it's a good idea to seek the advice of at least two or three damp proofing experts to guarantee that this is really the only option.


Condensation issues can certainly be improved through the use of dehumidifiers, which are a highly effective way to remove moisture from the air. Because dehumidifiers only mask the cause of the damp and not get rid of it, there are issues with this solution. If you are suffering from damp in any part of your home in Dorchester, you can call on a competent damp proofing company for the most reliable advice.

Some of the Benefits of Using Dehumidifiers

Here are some advantages of employing dehumidifiers:

  1. Prevents Rust and Corrosion: In areas with excessive amounts of moisture they help to stop metal tools and appliances from corroding and rusting.
  2. Health Improvements: By reducing humidity levels, dehumidifiers help mitigate the growth of dust mites and mould, common allergens that can cause respiratory problems and aggravate asthma and allergies.
  3. Protects Belongings and Property Structure: By preventing damp-related problems and safeguarding belongings from moisture damage, lower humidity levels ensure the structural stability of the premises is maintained.
  4. Reduced Odours: Creates a fresher and more delightful living environment by eliminating the musty smells that high levels of humidity cause.
  5. Comfort: By decreasing indoor humidity, the environment becomes cooler and more agreeable, which improves the conditions for living.
  6. 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 energy use.


The best recommendations for local professionals with regards to home improvement projects are generally family and friends. Before hiring any damp proofing services, you should always see if you can get at least two or three quotations from a variety of Dorchester companies. If you are in any doubt about any damp proofing company you should ask to look at professional membership certificates and accreditations.

Keep an eye out for qualifications and membership from bodies such as the Damp Proofing Association (DPA) or the Property Care Association, or contractors holding the CSTDB (Certificated Surveyor of Timber and Dampness) or the Certificated Surveyor in Remedial Treatments (CSRT) professional qualifications.

If your Dorchester damp proofing providers are members of either the DPA or PCA they will be suitably qualified and have the necessary experience to provide a first class service for your damp proofing issues. Such memberships also means that there are guarantees for any remedial work accomplished.

Positive Input Ventilation (PIV)

For alleviating damp problems within your home or business premises in Dorchester, Positive Input Ventilation (PIV) could be the perfect solution. Alleviating damp and mould in your home or condensation around your windows can be accomplished by reducing the humidity through Positive Input Ventilation. It accomplishes this by constantly circulating fresh air. Asthma and allergy sufferers can benefit from improved day-to-day life as a result of constantly refreshing and replacing the air inside your property, which leads to improved air quality, reduced odours and pollutants, and decreased dust mite allergens. Installing PIV systems in a roof space and ensuring that your house is fairly airtight are important considerations when opting for this solution. Gaps in windows or doors can cause fresh air to escape while allowing polluted air to enter, as air, similar to water, takes the path of least resistance.

Dehumidifier Installation

Maintaining comfortable and healthy indoor air quality, especially in locations with high humidity levels, necessitates the use of dehumidifiers. For the unit to perform optimally and last long, correct installation is of utmost importance.

Before installing a dehumidifier, one must carefully select an obstruction-free location with an electricity socket nearby. It's essential to ensure that the unit is placed on a flat surface and kept away from walls and furniture to allow for sufficient air circulation.

Next, the drainage system must be set up correctly to prevent water damage or overflow. The process may involve connecting the dehumidifier to a drain or attaching a hose to the unit. Regular maintenance, such as replacing the filter and cleaning, is also important for the effective operation of the dehumidifier.

Seeking professional help or referring to the maker's instructions is recommended to ensure a safe and successful dehumidifier installation. 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.

Cementitious Tanking

Cementitious tanking is a well-liked method for preventing the penetration of water in basements and cellars. Applying a cement-based water-resistant system to the floors and walls of the room is a crucial part of this process. It is possible to mix the tanking material on the job or purchase it pre-manufactured in a range of grades suitable for different substrates.

Cementitious Tanking Dorchester

If correctly applied for maximum effectiveness, cementitious tanking can provide a long-lasting and durable barrier against water penetration. Before application, the surface must be devoid of any contaminants or loose material and must be dry and clean to ensure effectiveness.

Professional installation by a skilled damp proofing specialist is recommended to achieve a long-lasting, high-quality result. With correct installation, cementitious tanking can be an effective and dependable solution for waterproofing cellars and underground spaces in Dorchester.

Issues With Black Mould in Dorchester

If you are experiencing symptoms of black mould in your Dorchester property, you might have an issue with Stachybotrys chartarum. This fungus is extremely toxic and produces a slime head called conidia. It is known as a primary cause of indoor air pollution and is also considered to be a health hazard. If you see indications of this type of mould in your home in Dorchester, you should contact an established damp proofing company right away, to get the best treatment.

Black Mould Dorchester

The first step in eliminating mould is to clean the affected 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 careful while using bleach, since it can burn and irritate your eyes. Also, make sure there is good ventilation in the area where you are working, to help clear away the fumes.

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

Woodworm Treatment and Prevention

Woodworm is a common issue that affects lots of buildings, particularly older properties in Dorchester. It is caused by the larvae of certain kinds of beetles that feast on the timber and can cause significant damage over time. Therefore, it is essential to take steps to treat and prevent these infestations.

The initial step in woodworm treatment is to identify the type of beetle that's causing the problem, as different types require different treatments. A professional woodworm specialist can perform an in-depth examination to assess the extent of the infestation and propose the best course of action.

Insecticides are a common method of treating woodworm, and can be applied in liquid or gel form. These treatments penetrate the timber and exterminate the larvae. For more severe infestations, fumigation might be the answer. The fumigation process involves sealing-off the area in question and releasing a gas into the space to eradicate the woodworm larvae.

To prevent future woodworm infestations, it is critical to make sure that the environment is not conducive to their growth. This can be accomplished by regulating humidity levels, adequate ventilation, and treating any existing woodworm as soon as it is identified.

DPC Replacement Dorchester

Safeguarding the structural integrity and visual appeal of your Dorchester property hinges on the timely replacement of a deteriorating Damp Proof Course (DPC). Over time, the existing DPC may become compromised, potentially leading to the onset of rising damp. Careful monitoring for signs like deteriorating brickwork, damp patches 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 necessitates thoroughness and precision to ensure a reliable seal against moisture ingress.

The choice of materials for the new DPC can vary depending on the specific needs of the home. 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 Dorchester home. Regular inspections and timely DPC replacement are essential for ensuring your property remains dry and structurally sound. (85222 DPC Replacement Dorchester)
