  • Penetrating Damp

  • Condensation

  • Rising Damp


The next paragraphs describe the sources of such problems with damp in Southsea, and the various techniques for preventing and solving them.


Common exterior issues like: cracked roof tiles, porous brickwork, defective drainpipes or gutters and blocked cavities, can all be principal causes of penetrating damp. In the interior of your property it can be caused by leaky or burst water pipes, cracked shower trays and overflowing bathtubs or sinks. If water continues to soak into the woodwork and walls, the noticeable signs in time are going to be damp, dark patches on walls, peeling or bubbling paintwork and blistered or broken plaster.

You can get wet rot in the timbers on your roof, if you have a leaky roof, and it has been left untreated for a while. This could prove very costly, because in the worst case scenario the structural integrity of your roof timbers could be compromised, meaning that you are going to need an entire new roof. Wet rot can be identified by black fungus appearing on your woodwork and a "spongy" feel to the rafters, together with an unfamiliar musty smell from the decaying timber. Upon identifying any of these wet rot signs, it's important to take action quickly to avert further harm and the potential expense of a roof replacement.

You shouldn't fret however, since to stop these problems from occurring, a few straightforward steps such as cleaning and checking your roof & gutters for leaks, inspecting pipes for leaks and repointing brickwork, should reduce such concerns. A knowledgeable Southsea damp proof service provider will check all these areas to help avoid any further problems, as part of solving your issues with dampness.


Condensation Damp Southsea UK (023)

There are numerous factors that can cause dampness, but condensation is one of the most common and easiest to spot. Small droplets of water form on cool surfaces when they come into contact with humid, warm air. Poor ventilation in areas with high humidity, such as in kitchens, bathrooms and boiler rooms, is the most common cause of condensation.

Simple solutions to reduce condensation involve wiping up any water droplets as soon as they form and making certain that there is sufficient ventilation in the trouble spots. You may need to upgrade or fit cooker hoods, extractor fans and air bricks, in order to redirect excess damp air from your property in Southsea.

There could be issues with sucking in damp air from the outside, and by completing an in-depth damp proofing survey a specialist in Southsea will be able to find things that contribute to the problem. Circulation and airflow needs to be regulated properly to effectively minimise condensation problems, and a certified damp proofing specialist will be able to give advice and offer solutions on this subject.

Damp Proofing Quotes in Southsea Hampshire


Ever since 1875, a damp proof course or membrane has been compulsory in all houses built in the UK. It is quite possible that you might not have one installed if your property in Southsea was constructed before this time. It's possible that your damp proof membrane or course could have been damaged somehow if you are experiencing rising damp problems in a house built after this year.

Although difficult to identify, "tide marks" on walls, crumbling or rotten skirting boards and white powdery deposits forming on walls or being found on floor surfaces, are all giveaway clues that you may have rising damp. It's feasible that you might have a rising damp problem if you have noticed one or all of these in your home.

Rising Damp Southsea Hampshire

The first step towards managing your rising damp should be to simply check whether or not you have a damp course on the external walls of your property in Southsea. To be sure of an adequate measure of protection the damp proof membrane should be above ground level by no less than 150 millimetres (approximately six inches). You can dig the surrounding earth away to generate this space if it's currently not sufficient, or you could install a damp course higher up if the former isn't plausible.

You could have more serious issues if you learn that your damp course is fine, and it may be that the moisture is seeping up from the ground, through your flooring, and into your property's walls, which is going to be even more worrying.

Damp proofing experts in Southsea can quickly detect and resolve rising damp problems using a variety of procedures. Older properties which either don't have a DPM at all, or have one which is damaged over a wide area, can have a damp proof cream (such as Dryzone or Permaguard) injected into the outside walls. Holes will be drilled at intervals in the brickwork, and a nozzle is used to inject the special cream, which then diffuses before curing to form an effective, horizontal waterproof barrier.

In cases where damp proofing cream is not a satisfactory solution, or when your membrane is too extensively damaged, putting in a new damp proof course could be neccessary. This is the most drastic of repair works, however it may be the only resolution to your rising damp issues.

Damp Proofers Southsea (PO4)

For smaller areas of membrane damage, another potential solution could be to coat with a waterproof (bitumen based) latex emulsion paint. This will be applied underneath your floor coverings, so tiles, wooden flooring and carpeting must be lifted before any work can be done. Also used as part of the tanking process to create a waterproof space, this is an especially effective treatment in cellar areas. Before the bitumen coating has has dried out completely, your Southsea damp proofing specialist might suggest applying building paper (a specialist foil backed membrane), for additional protection.

Tanking: The process of covering exposed surfaces in a watertight paint in a cellar or below ground area is referred to as tanking. This has to be applied at the base level of floors and walls, and so any wall covering and plaster must be removed and the appropriate surfaces prepared properly before work commences. You can replaster the walls and decorate over it, after the coating has completely dried. This is an extremely disruptive job since it has to be applied to a whole basement level or ground floor of a property, and it's preferable to get more than one specialist's opinion on whether this is the only answer to your damp problems.


Issues with condensation can certainly be improved through the use of dehumidifiers, which are an efficient way of lowering the moisture content in the air. The fact that these products just alleviate the cause of the damp and don't cure it, is the drawback with dehumidifiers. To get the most reliable advice if you are experiencing damp in any area of your house, you can call on a competent damp proofing specialist in Southsea.

Some Benefits of Using Dehumidifiers

Highlighted below are several benefits associated with the use of dehumidifiers:

  1. Health Improvements: Dehumidifiers contribute to lowering humidity levels, which in turn reduces the proliferation of dust mites and mould, allergens known to exacerbate asthma and allergies and lead to respiratory issues.
  2. Energy Efficiency: Some dehumidifiers enhance the efficiency of heating systems by drying the air, which simplifies the heating process and could lead to significant energy savings.
  3. Comfort: The decrease in indoor humidity levels can transform the environment into a cooler and more comfortable space, improving the overall living experience.
  4. Prevents Rust and Corrosion: In areas with excessive moisture they help to protect metal appliances and tools from rusting and corroding.
  5. Protects Structure and Belongings: The structural stability of the building is safeguarded against damp-related issues and belongings are shielded from moisture damage through the reduction of humidity levels.
  6. Odour Reduction: Leads to a fresher, cleaner, and more enjoyable living environment by removing the musty smells linked with high levels of humidity.


As with just about any home improvement project, the most reliable recommendations for a local specialist come from friends and neighbours. Always get at least 3 or 4 different estimates from a variety of companies, and if in any doubt you can ask to see evidence of qualifications and professional memberships, before signing up for any damp proof services.

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

Membership of either the DPA or PCA guarantees that your preferred damp proofing provider is suitably qualified and has the appropriate experience to provide a high quality damp proofing service. Any remedial work carried out by any one of their members also comes with a guarantee.

Cementitious Tanking

A popular method for preventing the ingress of water in cellars and basements is cementitious tanking. This procedure necessitates the application of a cement-based water-resistant system to the floors and walls of the room or space. Tanking material is available in different grades suitable for a range of substratum, which can either be mixed in-situ or pre-manufactured.

Cementitious Tanking Southsea

To achieve the best possible outcome, cementitious tanking must be applied correctly, and if this is accomplished it can provide a long-lasting, durable barrier against water penetration. Before application, the surface must be devoid of any contaminants or loose material and must be clean and dry to ensure effectiveness.

To achieve a long-lasting, high-quality result, it is recommended to choose professional installation by a skilled damp proofing specialist. Proper installation of cementitious tanking can offer an effective and reliable solution for waterproofing cellars and basements in Southsea. To maintain its efficiency and prevent moisture penetration, any damage or wear must be dealt with through regular system inspection.

Positive Input Ventilation (PIV) Southsea

With its ability to reduce damp issues within your property in Southsea, PIV (Positive Input Ventilation) could be the perfect solution. Positive Input Ventilation can aid in reducing humidity levels, which can alleviate damp and mould in your dwelling or condensation around your windows. Achieving this is accomplished by the constant supply of fresh air. The continual refresh and replacement of air inside your home has been shown to reduce odours and pollutants, decrease dust mite allergens, and enhance air quality, ultimately benefiting allergy and asthma sufferers in their day-to-day lives. Installing PIV systems in a loft and having a relatively airtight home are important considerations to keep in mind when opting for this solution. Fresh air can escape through spaces and gaps around windows or doors while contaminated air enters, as air takes the path of least resistance, similar to water.

Woodworm Treatments

Unfortunately, woodworm is a common problem that can affect buildings of all ages. The larvae of certain types of beetles feast on timber, which can lead to considerable damage over time. Nonetheless, there are a number of steps that can be taken to prevent infestations and address any existing issues.

The initial step in woodworm treatment is to identify the species of beetle that is causing the problem, as different types require different treatments. A professional woodworm specialist can carry out an extensive inspection to determine the level of the infestation and recommend the best course of action.

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 larvae. For more severe infestations, fumigation could be necessary, which involves sealing the affected area and releasing a gas into the space to kill off the larvae.

In order to thwart the possibility of future woodworm infestations, it is essential to establish an unsuitable environment for their growth. This can be accomplished through the implementation of measures such as regulating humidity levels, ensuring proper ventilation, and treating any existing woodworm infestations immediately upon discovery. By taking these precautions and adopting a preventative approach, one can effectively reduce the risk of woodworm damage and avoid the expense associated with remediation.

In conclusion, it is essential to use an established woodworm specialist in Southsea to identify, assess, and treat any infestations in order to preserve the structural integrity of the building.

Dehumidifier Installation

Dehumidifiers play a vital role in ensuring comfortable and healthy indoor air quality, particularly in regions with high levels of humidity. To achieve the unit's optimal longevity and performance, correct installation cannot be overlooked.

Dehumidifier Installation Southsea

The selection of an obstruction-free location with a power socket nearby is a crucial step before dehumidifier installation. Sufficient air circulation requires placing the unit on a flat surface and keeping it away from furniture and walls.

The next crucial step is to ensure the drainage system is set up correctly to prevent overflow or water damage. It may require attaching a hose to the unit or connecting the dehumidifier to a drain. The effective operation of the appliance necessitates regular maintenance, such as replacing the filter and cleaning.

The correct selection of a dehumidifier's size and location can have a substantial impact on its performance and benefits. It's recommended to refer to the manufacturer's instructions or seek the assistance of a professional to ensure a safe and successful 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.

DPC Replacement Southsea

Safeguarding the structural integrity and visual appeal of your Southsea 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 spots 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 the ingress of moisture.

The choice of materials for the new DPC can vary depending on the specific needs of the property. Traditional methods like bitumen or slate 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 Southsea property. Routine inspections and timely DPC replacement are essential for ensuring your property remains dry and structurally sound. (85222 DPC Replacement Southsea)
