Condensation Damp Dulwich UK (020)

One of the most common forms of damp in Dulwich homes, condensation is very easy to identify. When a cool surface makes contact with moist, warm air, water forms as small droplets upon that surface. It often forms due to poor ventilation in places where high humidity is present, i.e. kitchens, bathrooms and boiler rooms.

Wiping away any droplets that form, and making sure that you have adequate ventilation in the main trouble spots, are amongst the most basic answers to such problems. To help remove the moist air from your property, you might need to upgrade or install air bricks, extractors and cooker hoods.

There could be issues with drawing in moist air from the outside, and by carrying out a detailed damp proofing survey an expert in Dulwich will find circumstances that play a role in the situation. To satisfactorily control condensation, airflow has to be properly regulated. A certified Dulwich damp proofing technician will gladly offer advice and solutions to accomplish this in your home.

Damp Proofing Quotes in Dulwich Greater London


A damp proof course or membrane has been fitted as standard on homes built in the United Kingdom since 1875. You may not have a damp proof course on your home or property in Dulwich if it was built prior to this period. If your home was constructed after this year, but you're still experiencing rising damp, it could be that your damp proof membrane or course has been damaged.

Although notoriously hard to distinguish, crumbling or rotten skirting boards, tide marks on walls and a white powdery deposit being found on floor surfaces or forming on walls, are all giveaway clues that you may have rising damp. It's plausible that you may have a rising damp problem if you have noticed one or all of these.

Rising Damp Dulwich Greater London

Solving rising damp problems can be as easy as checking your home's outside walls and seeing if you can spot a damp course. It needs to be 150mm (approximately six inches) above ground level for satisfactory protection. If this isn't the situation you might be able to dig the ground away to create this gap, or if this isn't feasible, you could put in a DPM (damp proof membrane) higher up.

If this is not the root cause of the problem and your damp proof course is in fact correct, there could be more problematic issues to resolve caused by the moisture coming up from the ground beneath, through your floor, and into the walls of your property.

Damp proofing professionals in Dulwich will quickly detect and remedy rising damp using a variety of methods. A damp proof cream (such as Permaguard or Dryzone) can be carefully injected into your walls if you have an older home with no DPM, or one that's damaged over a wide area. This special cream is injected with a nozzle into evenly spaced holes drilled along the mortar joint, and before the cream can cure it diffuses into the surrounding brickwork forming a barrier that is repellent to water.

If the damage to the DPM is too severe, or if damp proofing cream injection is not a suitable treatment, you may need to put in a brand new damp proof course. Although this is obviously a fairly drastic course of action, it may be the only way to resolve your rising damp problems effectively.

Another possible remedy for less severe areas of damage could include painting with a bitumen based, waterproof latex emulsion. This has to be applied under your floor coverings, so tiles, carpeting and laminate flooring must be lifted before any work is done. Also used as an integral part of the tanking procedure to create a waterproof space, this is an especially efficacious treatment in basement areas. Your Dulwich damp proofing technician might suggest a layer of building paper (a special foil backed membrane) before the bitumen paint has completely dried, further protection in these trouble spots.

Tanking: The process of covering exposed surfaces in a watertight paint in a below ground area such as a cellar or basement is known as "tanking". Because this coating must be applied on the base surfaces of walls and floors, any wall covering and plaster must be removed before any work can begin, and the surfaces prepared properly. You can replaster any wall surfaces and decorate over the top of it, after the paint has dried completely. Since it needs to be applied to an entire ground floor or basement level of a building, this is a very disruptive process. It is therefore preferable to call in at least two or three damp proofing companies to make certain that this is really the only possible resolution.


To help ease condensation issues, you could always try dehumidifiers, which for removing moisture from the air, are really efficient. Because dehumidifiers only alleviate the cause of the damp and not get rid of it, there are disadvantages to this solution. If you're suffering from damp in any area of your home in Dulwich, you should call on a certified damp proofing specialist for the most reliable advice.


Friends and relatives should invariably be the first choice when you are trying to get recommendations and testimonials for local professionals. Where possible you should always see if you can get at least three different quotations from a number of companies, and before hiring any particular damp proof providers, you can ask to see professional membership certificates and qualifications, as a verification of their integrity.

Professional Dulwich damp proofing companies ought to be signed up members of either the Damp Proofing Association (DPA) or the PCA (Property Care Association), or have professional qualifications from the CSRT (Certificated Surveyor in Remedial Treatments) or the Certificated Surveyor of Timber and Dampness.

Membership of the PCA or DPA guarantees your chosen damp proofing provider is well qualified and has the appropriate experience to perform a first class damp proofing service. In addition, it offers a guarantee over any work completed by one of their membership.

Woodworm Treatment and Prevention in Dulwich

Unfortunately, woodworm is a common issue that can affect buildings of any age. The larvae of certain types of beetles gnaw away at wood, which can lead to major damage over the years. However, there are several steps you can take to prevent woodworm infestations in the future and treat any pre-existing issues.

The starting point of woodworm prevention is to identify the signs of an infestation. These include tiny holes in the wood, sawdust or frass on the floor or nearby surfaces, and damaged or weakened timber. If you notice any of these signs, it's vital to act quickly and call a professional woodworm specialist. Once an infestation is identified, the species of beetle causing the problem needs to be identified since different types call for different treatments. Experienced woodworm specialists can conduct an inspection and suggest the best treatment plan.

When it comes to treating woodworm, insecticides are one the most effective solutions, and these can be applied in gel or liquid form. These treatments seep into the wood and eliminate the woodworm larvae. For more severe infestations, fumigation might be required.

To prevent woodworm infestations, it's important to ensure that the environment isn't conducive to their growth. This can be accomplished through proper ventilation, maintaining appropriate humidity levels, and treating any existing woodworm as soon as it is identified. Using wood that has been treated with a woodworm repellent can also prevent future infestations.

Condensation Control

The control of condensation plays a crucial role in maintaining a healthy and pleasant indoor environment. The formation of water droplets happens as warm, moisture-laden air interacts with colder surfaces, resulting in condensation. Uncontrolled condensation can result in mould growth, damage to building materials, and the deterioration of indoor air quality.

Condensation Control Dulwich

To control condensation, adequate ventilation is essential to regulate the amount of humidity and promote air flow. Additionally, using double-glazing and insulation can help reduce temperature differentials and minimise condensation. Creating a more pleasant working or living environment is achievable by effectively managing condensation, which helps prevent potential problems.

Double-glazed windows and insulation can be used to help reduce temperature differentials and minimise condensation. Insulation prevents cold surfaces and warm, moist air from touching each other by acting as a barrier. A reduction in temperature difference makes it less likely for condensation to form on surfaces like walls, windows and ceilings. Double-glazed windows are effective at maintaining an even inside temperature, further curbing condensation, as they feature two panes of glass with an insulating layer in between.

Another effective condensation control tactic is to address moisture sources head-on. Showering, cooking, and activities like drying clothes indoors can all release large amounts of moisture into the air. Exhaust fans and proper ventilation in kitchens and bathrooms can prevent an excessive build-up of humidity. In areas susceptible to high moisture content, dehumidifiers can help maintain optimum indoor humidity levels.

A more pleasant living or working environment can be created by effectively managing condensation and preventing potential issues. Protecting buildings and safeguarding the health and well-being of occupants are both benefits of controlling the indoor environment. Areas where condensation might occur can be identified by conducting regular maintenance checks, such as inspecting seals around doors and windows for gaps. New condensation control technologies and strategies continue to emerge as our understanding of indoor air quality and building science advances, providing even more effective ways to ensure a comfortable and healthy indoor environment. In conclusion, a wide-ranging condensation control strategy must include proper insulation, moisture source management, ventilation, and innovative technologies.
