The most common mistakes in facade maintenance and how to avoid them
25. 9. 2025
A house facade together with insulation is definitely not a cheap investment and many other costs depend on it. That is why it is very important to provide the facade with regular care and maintenance that will keep it in excellent condition for as long as possible.
Unfortunately, many owners and managers of apartment buildings make mistakes when maintaining facades, which often lead to faster material damage, unnecessary repair costs, or even damage to the facade itself. We will show you the most common mistakes people make and advise you on how to avoid them.
Postponing regular maintenance
One of the most common mistakes is postponing maintenance. Owners or property managers often start dealing with it only when the facade is almost black or green and covered with a large colony of microorganisms. Cracks or peeling plaster also begin to appear. Irregular maintenance increases the risk of moisture penetration and subsequent damage to the masonry, which can lead to expensive repairs.
Do not leave facade cleaning until the last moment. The facade should be cleaned and repainted regularly, even when it does not appear “that dirty yet” at first glance. Inspect the facade at least once a year, ideally after winter, and deal with minor issues immediately. Prevention is always cheaper than later repairs and new coatings.
Using inappropriate cleaning products
Some owners or property managers attempt maintenance on their own or choose the cheapest companies. Unfortunately, this often leads to the use of cheap, unsuitable, and aggressive cleaning products that can damage the surface layer of the plaster.
It is important to use gentle but effective products that can remove microorganisms and dirt without damaging even delicate facade surfaces.
Ignoring biological contamination
Green algae coatings, moss, or mold on the facade are often underestimated. However, biological contamination not only spoils the appearance of the building but can also damage the structure of the plaster, promote moisture penetration, and most importantly pose a health risk to residents.
During cleaning, it is necessary to remove not only the surface layer of dirt but also all algae, moss, and mold. The ideal approach is to use the correct water pressure together with specialized cleaning products.
Unprofessional repairs of cracks and damage
Owners often attempt repairs themselves without the necessary knowledge. Or, as mentioned above, they contact companies that may offer a lower price but lack sufficient experience. This can lead to poorly executed repairs or unprofessional facade cleaning.
Regular facade maintenance is neither complicated nor expensive if done properly and on time. When choosing a company to clean and repaint the facade of your building, make sure to focus on its experience and references. Unprofessional cleaning can damage the facade and increase the cost of repairs.
