Rising damp treatment

Rising damp is when moisture climbs up the walls, and sometimes even floors, soaking up moisture from below the earth. Usually, it will reach a maximum height of 900 mm in your walls, but this will depend on the types of material in the ground levels outside. Horizontal tide mark will generally be formed by salt deposits, there will be discolouration below this, your wallpapers will be peeling, and it is also possible that white salts have been drawn out of the brickwork by the moisture.

Every building is surrounded by natural moisture in the air that will be trying to find its way into a dry structure of a building. This is why it is paramount you get a specialist in so that you can correctly diagnose the source of rising damp in your property. Southern Damp Proofing Ltd can also offer low maintenance damp works in order to safeguard your home.

New buildings will often be built with a rising damp treatment. This will be a damp proof course in the walls. This will have an effect on how likely it is that rising damp will occur. If the property is older, it is more likely to be damaged because of rising damp. The most common symptom of rising damp is damage to interior wall coverings and plaster.

Several types of floor can also display staining and moist patches. Without the assistance of a damp proof membrane or course, materials such as brick and stone can soak up moisture. This can happen to the most beautiful and well-maintained of properties, as original stone or quarry tiled floors are susceptible to damp. It can often be overlooked that damp may occur.

The worst thing about damp is the fact that if it is not treated it will continue to rise, it may cause interior timber and floor joists to rot, and it will ultimately get worse. Not only can it make you ill, it can also bring your home’s structural integrity into question. It is best to treat damp as soon as you suspect.

Penetrating damp treatment

Penetrating damp is a result of different issues with moisture. Various types of fabric within the building can allow water to leak into walls or floors. This may make guttering of pipes ineffective, if your flashing is faulty, it may make cause poor pointing.

In order to treat penetrating damp, the source of the problem must first be identified. Only then can it be corrected, and the flow of water improved. After this source is identified, finding out the best treatment option can also begin.

If your case of penetrating damp is minor, it can be discovered and treated through various DIY techniques.

However, if your case of penetrating damp is more serious, we would recommend professional and expert help. This is because penetrating damp can cause the need to replace plasterwork. It may have caused wet or dry rot, and it may have also caused harmful black mould. The dampness may have been caused by bridging through wall insulation, we can fix that.

If there are damp problems in your home, it is best to treat them first before decorating or renovating. While you can start your renovation process at any time, the longer you wait to treat damp, the worse it will get.

Dry rot treatment

Dry rot is a slightly different type of damp. It is caused by a specific species of fungi that will eat into your woods, making it stronger and stiff. Any decay is caused by dry rot. It will result in cracks and darkly coloured deterioration.

First of all, to treat dry rot you must identify it at its source. After this, you must remove the source of moisture. This will starve the fungi, meaning that it can no longer flourish. After the source has been removed, the next stage of treatments can occur. This will typically involve the removal of plaster, the application of fungicide, and the fixing of any issues with the structural integrity within the timber. The final step may include the removal and replacement of decorative and/or structural timbers.

When it comes to treating dry rot, it can seem insurmountable. However, at damp proofing, we have qualified and experienced surveys, technicians, and specialists.

Treatment for wet rot

Wet rot is an umbrella term used to describe a variety of different types of wood rot. The most various types of wood rot caused by different fungal species. The most common is ‘cellar fungus’ (also called Coniophora puteana).

Issues involving wet rot can range from mild to extremely severe. Wet rot can affect structural integrity in timbers. This means the sooner the issue is tackled the better. It is crucial for severe wet rot to be fixed.

Wet rot is usually caused by high moisture content, however, this can come from a variety of different sources. So, identifying this source of moisture and attending to it is crucial in the treatment of wet rot.

Condensation is easily the most common cause of damp in buildings. It accounts for most of the damp problems that are reported. It can affect both new and old buildings and can be specifically problematic with older buildings that have been modernised. Effective treatments such as double glazing and insulation can have a negative effect, as the property will not naturally ‘breathe’. As time progresses, we are spending more and more time inside our properties, which can also contribute to increasing levels of moisture in your property, and unfortunately increase the risk of illness, too.

There is a relationship between condensation and peeling wallpaper, wet window, and mould growth. This is what you will notice first, and how bad your mould issue is will show you how bad the problem is. Unfortunately, mould caused by condensation is usually found on decorative surfaces, especially wallpapers. This can mean it has permanent damage if left untreated. There are also many cases of people reporting illness due to mould, and it can also create a musty odour.

Ventilation is crucial for your home to alleviate the problem, as well as removing sources of penetrating damp. This way moisture and air will flow more naturally and effectively. In some cases, it may be necessary to warm up walls and wallpapers as well as ventilating the property, this is to minimise the risk of dew point temperature being reached. Dew point temperature is where moisture droplets form on your surfaces. Increasing temperature and ventilation will help treat signs of mould and possible side effects associated with condensation.

At Southern damp proofing we offer a variety of ventilation systems, including economic or traditional sleeved wall vents. This will help with airflow in your house, which will alleviate condensation. There will be little heat loss and our mechanical vents are quiet, energy efficient and low maintenance. While you may notice that damp is there, you certainly won’t notice the ventilation systems.

Timber treatment

Timber treatment will preserve your wood. The treatment will penetrate your timber and coated with a protective preservative, that will stave off decay caused by insects and wood-destroying fungi.

The preservative is placed deep inside the timber structure through a vacuum and pressure. This area of the timber is known as the Heartwood because it is what helps the timber stay structurally sound. The vacuum will remove any air cavities from the timber so that there will be space for the preservative to be forced into the wood with extreme pressure.

Any timber that is placed outside, especially timber that will touch the ground, is exposed to the elements. It will need some sort of preservation to protect it from environmental challenges.

The amount of preservative that is needed to get the best results will be decided by the intended use of the timber. They are also based on the level of threat posed by insects, fungi or decay. This will depend on the environment. Specialist replastering is a crucial part of the treatment of rising damp.

A damp proof course will prevent moisture from rising into walls. Rising dampness will bring in soluble salts into the plaster and brickwork. These salts are hygroscopic. These hygroscopic salts will prevent wall plaster from effectively drying out. This means that it is paramount to replace these with a salt retardant render. We recommend Kenwood waterproof rendering system, in order to keep a good-looking dry internal finished.
