Damp Proofing Quotes in Merthyr Tydfil Wales


A damp proof course or membrane has been installed as standard on houses constructed in the United Kingdom since 1875. If your home or property was constructed before this period it's conceivable you might not have one installed. If you're suffering with rising damp in a home built after this date it may be that your DPM has been damaged somehow.

Although rather difficult to identify, a white powdery deposit being discovered on floor surfaces or appearing on walls, rotten or crumbling skirtings and "tide marks" on walls, are all giveaway clues that you may have rising damp. It is possible that you may have a rising damp problem if you've noticed one or all of these in your home.

Rising Damp Merthyr Tydfil Wales

Purely checking your home's external walls to see if you have a damp course can be one step towards managing your rising damp problems. It ought to be 150 millimetres (around six inches) above ground level for satisfactory protection. If this isn't the situation you might be able to dig away the ground to create this gap, or if this isn't plausible, you can put in a damp course higher up.

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

Using a variety of procedures, damp proofing technicians in Merthyr Tydfil will swiftly identify and remedy your rising damp problems. If you've got a somewhat older property with no damp proof membrane or it is damaged over a considerable area, a damp proofing cream (such as Dryzone or Permaguard) can be carefully injected into your wall. Evenly spaced holes are drilled at intervals in the mortar joint, and a nozzle is used to inject the special cream, which then soaks into the surrounding brickwork before curing to form an effective waterproof barrier.

If the damage to your damp course membrane is too extensive, or if damp proofing cream isn't a suitable treatment, you may have to install a brand new damp proof course. Unfortunately this is taking repair work to the extreme, but it may be the only answer to your damp problems.

Painting with a waterproof (bitumen based) latex emulsion, is another potential option for less severe areas of membrane damage. Since this is going to be applied beneath your current floor coverings, carpets, tiles and wood flooring will have to be lifted and removed before this process can begin. In cellar areas this is a particularly efficacious treatment, and will form a part of the tanking procedure that's used to make rooms watertight. Your Merthyr Tydfil damp proof expert may recommend the use of building paper (a special foil backed membrane) before the bitumen coating has has dried out completely, further protection in these problem areas.

Tanking: In areas of a house which are below ground, like cellars, "tanking" is the process where surfaces that are exposed are covered in a waterproof coating. Because this coating has to be applied to the base surface of floors and walls, any plaster and wall covering must be taken off before work begins, and all surfaces correctly prepared. When this coating has been put on, it should be permitted to dry thoroughly before replastering any walls and decorating on top of it. This is an incredibly disruptive process as it needs to be applied to a whole basement level or ground floor of a property, and it is wise to obtain more than one expert opinion on whether this is really the only resolution to your rising damp problems.

Dehumidifier Installation

Dehumidifiers are an essential appliance that must be installed to maintain a comfortable and healthy indoor air quality, particularly in regions with high levels of humidity. For the unit to perform optimally and last long, correct installation is of utmost importance.

For correct dehumidifier installation, it's vital to select a location that is free from obstructions and has a nearby power source. It's essential to ensure that the unit is placed on a flat surface and kept away from furniture and walls to allow for sufficient air circulation.

The next key step is to ensure the drainage system is set up correctly to prevent overflow or water damage. Connecting the dehumidifier to a drain or attaching a hose to the unit may be required to complete the process. The effective operation of the appliance necessitates regular maintenance, such as cleaning or replacing the filter.

The space or room where the dehumidifier will be installed should dictate the size of the dehumidifier, which is important to consider. For a safe and successful dehumidifier installation, it's recommended to seek the help of a professional or consult the manufacturer's instructions. Proper installation and servicing of a dehumidifier can significantly improve indoor air quality, mitigate moisture-related problems, and enhance overall comfort in homes or workplaces.

Condensation Control Merthyr Tydfil

Control of condensation is crucial for maintaining a healthy and pleasant indoor environment. Condensation occurs when warm, moisture-laden air comes into contact with cooler surfaces, leading to the formation of water droplets. Damage to building materials, mould growth, and the deterioration of indoor air quality can occur as a consequence of uncontrolled condensation.

Essential for controlling condensation is adequate ventilation, which regulates the level of humidity and promotes air flow. The use of insulation and double-glazed windows assists in reducing differences in temperature and minimising condensation. By managing condensation effectively, you can create a more pleasant living or working environment and avoid potential problems.

Double-glazed windows and insulation can also help to make a difference in reducing temperature differentials and minimising condensation. Insulation prevents cold surfaces and moist, warm air from touching each other by serving as a barrier. When the temperature difference is reduced, condensation is less likely to form on surfaces like walls, ceilings and windows. Double-glazed windows are effective at suppressing condensation by maintaining an even inside temperature. They feature 2 panes of glass with an insulating layer between.

To control condensation effectively, one strategy is to tackle moisture sources head-on. Drying clothes indoors, cooking and showering and similar activities can all release moisture into the air and cause issues. Kitchens and bathrooms with exhaust fans and good ventilation are less likely to have excessive humidity buildup. In areas susceptible to high moisture content, dehumidifiers can help maintain optimum indoor humidity levels. (67841 - Condensation Control Merthyr Tydfil)
