Damp Proofing Quotes in Havant Hampshire


Since 1875, a damp proof course has been compulsory in all houses built in the United Kingdom. You may not have a damp proof course installed on your home in Havant if it was built prior to this period. It is a possibility that your DPM might have been damaged in some way if you are experiencing rising damp issues in a property built after this year.

It can be difficult to distinguish rising damp, however some giveaway indications are; crumbling or rotten skirtings, white powdery deposits appearing on walls or being found on floor surfaces and tide marks on walls. If you notice or think you might have any of these signs, it's possible you have a problem with rising damp.

Rising Damp Havant Hampshire

Dealing with rising damp issues can be as simple as checking your outside walls to see if you can spot a DPM. For satisfactory protection it ought to be 150mm (about 6") above the level of the ground. If you find this gap doesn't exist, you could dig away the ground to increase it, or if this approach is not possible, a higher DPM will need to be put in.

If this is not the problem and your damp course is in order, there could be more serious issues to resolve caused by the moisture rising up from the ground beneath, through your floor, and into the walls.

Havant damp proofing experts will quickly be able to identify the cause of your rising damp issues, and employing a number of different techniques will soon deal with the problem. A damp proof cream (such as Dryzone or Permaguard) can be injected into your walls if you've got a somewhat older home with no damp proof course, or it is damaged over a considerable area. This calls for drilling holes at intervals along the brickwork and the cream injected with a special nozzle to plug the spaces behind the brickwork down to below ground level.

Another remedy for minimal areas of membrane damage may include painting with a bitumen based, waterproof latex emulsion. This has to be applied underneath your floor coverings, so tiles, carpeting and wooden flooring must be lifted prior to work being done. This is particularly effectual in basement areas as an integral part of the tanking process to create a room which is watertight. For further protection in these troublesome areas, your Havant damp proof specialist may recommend the use of building paper (a specialist foil backed membrane) before the bitumen coating has completely dried out.

Tanking: Tanking an area, such as a basement or part below ground space, is a process of covering any exposed surfaces with a waterproof paint. Since this waterproof coating must be applied to the bare surface of floors and walls, all plaster and wall covering must be taken off before any work can commence, and all surfaces prepared properly. Once this paint has been applied, it should be permitted to dry thoroughly before replastering and decorating over the top of it. This is a really disruptive job as it must be applied to a whole basement level or ground floor of a building, and it is recommended that you obtain more than one expert opinion on whether this is really the only answer to your rising damp problems.

The longevity of cementitious tanking can be assured through routine maintenance. Inspecting the system routinely and addressing any wear or damage is important for preserving its efficiency and preventing moisture ingress.

Dehumidifier Installation

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

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

Setting up the drainage system properly is the next step to prevent water damage or overflow. The process may involve connecting the dehumidifier to a drain or attaching a hose to the unit. Routine maintenance, such as replacing the filter and cleaning, is also important for the effective operation of the appliance.

Proper installation and maintenance of a dehumidifier can significantly improve indoor air quality, mitigate moisture-related problems, and enhance overall comfort in homes or businesses.

A crucial element in maintaining a healthy and comfortable indoor environment is the control of condensation. Formation of water droplets arises from the contact between warm, moist air and colder surfaces, indicating the occurrence of condensation. The consequences of uncontrolled condensation include damage to building materials, mould growth, and the deterioration of indoor air quality.

Condensation Control Havant

Achieving condensation control relies on proper ventilation, which regulates the level of humidity and ensures adequate the circulation of air. To minimise condensation and reduce temperature differentials, consider using double-glazed windows and insulation. Effective condensation management enables the prevention of potential problems and the creation of a more pleasant working or living environment.

Insulation and double-glazed windows can also help to reduce temperature differentials and minimise condensation. Cold surfaces are prevented from coming into direct contact with warm, moist air by insulation, which serves as a thermal barrier. When the temperature difference is reduced, condensation is less likely to form on surfaces like ceilings, windows and walls. Double-glazing is effective at maintaining a uniform inside temperature, which inhibits condensation. It features 2 panes of glass with an insulating layer in between.

Direct addressing of the sources of moisture is another strategy for effective condensation control. Moisture is released into the air by activities such as showering, cooking and drying clothes indoors. Using exhaust fans in kitchens and bathrooms and ensuring adequate ventilation during these activities can prevent an excessive build-up of humidity. Dehumidifiers can be used to help maintain optimal indoor humidity levels in areas at risk of high moisture content.

By effectively dealing with condensation, you can help to create a more comfortable living or working environment and avoid potential issues. Controlling the interior environment ensures the health and well-being of occupants, in addition to protecting buildings. To identify locations where condensation might occur, perform frequent maintenance checks, such as examining seals around windows and doors for gaps. As our understanding of building science and indoor air quality advances, so too do new condensation control strategies and techniques, providing even more effective ways to ensure a healthy and comfortable indoor environment. All in all, a wide-ranging condensation control strategy must include proper moisture source management, insulation, ventilation, and cutting-edge technologies. (44462 - Condensation Control Havant)
