  • 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.

Wet rot can occur in the timbers of your roof if you've got a leaky roof which is neglected for some time. Wet rot doesn't spread into brickwork, but having it can mean that in the worst case scenario your roof timbers become structurally unsound, requiring a new roof. Wet rot can be identified by black fungus appearing on your woodwork and a "spongy" feel to the timber, coupled with an unfamiliar musty smell from the rotting wood. Promptly addressing the issue is essential if you observe any of these wet rot indicators, as it can help prevent further harm and the potential necessity of expensive 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 possibly be issues with sucking in moist air from outside, and by conducting an in-depth damp proofing survey a specialist in Southsea will find circumstances that give rise to the problem. To effectively minimise condensation problems, air circulation must be regulated properly. An experienced Southsea damp proofing technician is well qualified to offer advice and solutions in connection with this.

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.


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

In cellars and underground spaces, cementitious tanking is a favoured method of preventing water penetration. To the floors and walls of the area, a cement-based water-resistant system is applied as part of this process. A range of grades suitable for various substratum and the choice of being pre-manufactured or mixed on-site are attributes of the tanking material.

Cementitious Tanking Southsea

For maximum effectiveness, cementitious tanking must be applied correctly, as it can provide a long-lasting and durable barrier against water penetration. For optimal results, the surface must be free from any contaminants or loose material and must be dry and clean before application.

A high-quality, long-lasting result can be attained by opting for professional installation by a skilled damp proofing specialist. With proper installation, cementitious tanking can provide a reliable and effective solution for waterproofing cellars and underground spaces in Southsea.

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 necessitates 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 crumbling plaster, damp patches or deteriorating brickwork 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 care and precision to guarantee a dependable barrier against moisture ingress.

When it comes to the new Damp Proof Course, the materials at your disposal exhibit a range of options, spanning from conventional approaches like slate or bitumen to modern alternatives like chemical injections. A well-executed DPC replacement serves a dual purpose, preventing further moisture-related deterioration and preserving the overall health of your indoor environment, all while safeguarding the value of your Southsea property. Routine inspections and timely DPC replacement efforts play a pivotal role in ensuring your home remains both dry and structurally resilient. (40713 DPC Replacement Southsea)
