Facade renovation – preventing consequential damage, maintaining value and protection


Facade renovation - professional & competent

A facade with crumbling plaster, a weathered coat of paint or other defects not only leaves an unfavourable visual impression. It can also no longer fully fulfil its function as a protective building envelope. Therefore, if your house is affected by such defects, you should think about a timely facade renovation to avoid consequential damage in the long term and not reduce your living comfort. Ultimately, a facade renovation also serves to maintain the value of your property.

Signs of a necessary facade renovation

After a certain age, it makes sense to inspect the façade of your property regularly. This allows you to detect any damage in good time and take countermeasures at an early stage. There are various signs that a façade renovation is necessary. These include an infestation of algae or fungi, moisture and frost damage in the masonry, crumbling plaster and hollow spots as well as weathering of the paint. Another point is the question of whether your house still meets contemporary energy efficiency requirements.

Algae and fungi spread on damp spots on the walls, which usually turn green or black. Algae growth is not infrequently clearly visible and can lead to fungal infestation if not combated. It is best to have an analysis carried out by a specialist company such as MVM AG. Any necessary façade cleaning should also be carried out by experts

Moisture is an archenemy of masonry. If it is not professionally removed, there is a risk of infestation with algae, mould and other fungi. Cracks and blisters due to frost damage are also possible "sources of infection". You should then immediately tackle a façade renovation and also retrofit effective insulation.

If you discover parts of the façade where the plaster is crumbly and crumbling away, or if you recognise hollow spots by tapping lightly, call in a specialist company immediately. As a rule, this is due to damage that can have serious consequences in the long term. With the support of a thermal imaging camera, our staff will locate the damage and advise you in detail on the necessary countermeasures.

Weather influences such as humidity, temperature fluctuations and strong sunlight attack the coating in the long term, especially on wooden façades. Check the surface with a wipe test. If residues remain on your hands and fingers, a new primer and a new coat of paint are due. MVM AG is also the right contact for this work.

Older properties no longer meet today's demands and regulations for optimal energy efficiency. Effective thermal insulation is therefore not only recommended, but in many cases even mandatory. You will reduce your heating costs and make a significant contribution to environmental protection. Thanks to the savings, the investment pays for itself in just a few years. In addition, there are subsidy programmes for renovation in the individual cantons. Our experts at MVM will be happy to inform you about the possibilities.

Properties of different facades

In order to better understand and assess damage to a facade, you should be aware of the characteristics and differences between rendered, clinker and wooden facades.

A plastered façade is uncomplicated and cost-effective. Depending on the material composition of the exterior walls, the plaster is applied directly or onto a thermal composite system. Thanks to modern techniques, there is a wide variety of designs here with types of plaster and colours. However, a plaster facade should be cleaned, checked for damage and painted at regular intervals by a specialist company such as MVM.

Clinker facades are easy to maintain and provide good protection for the building envelope. They are bricked up before the actual exterior wall, with efficient thermal insulation placed in the gaps. If the work is carried out carefully, a clinker facade offers a long and maintenance-free service life. A complete renovation will thus hardly be necessary. The clinker facade should only be cleaned now and then, for example with a high-pressure jet.

For wooden facades, a substructure of wooden slats is first attached to the masonry. Wooden elements are then attached to this, creating a curtain-type, rear-ventilated facade. The whole should be protected by a canopy. Wooden facades require regular, careful maintenance so that the material does not weather.

What work can be involved in a facade renovation?

With our profound know-how, we know which work steps are necessary for the different types of façades. First, we carry out a thorough inspection for possible defects. Minor damage can be quickly repaired, for example small cracks or cavities. However, if the defects go deeper and endanger the masonry, a thorough and complete façade renovation is required. Usually as part of a new rendering or, in the case of wooden façades, a new primer plus a new coat of paint. It may also be necessary to improve the thermal insulation – if present – or to install it completely new.

MVM AG is very familiar with all this work and is a reliable partner for your façade renovation. It is best to arrange an on-site appointment with us so that we can inspect your façade and check for defects.
