Facade cleaning: do it yourself or have it done by a professional?

A facade cleaning makes old walls shine again. Especially in summer, the walls of a house should shine. It is usually only then that dirt and moss can be seen on the façades. This not only looks unkempt and outdated. Dirt and moss on the façade can also damage the plaster. If the plaster is already porous, moss can spread in fine irregularities and cracks and cause additional damage to the plaster. What is the best way to clean facades? Should a professional do the cleaning or can you do it yourself? You should always bear this in mind when cleaning a façade.

When should a professional clean the facade?

Should a facade cleaning be done by a professional or can anyone do it themselves? That all depends. First you should ask yourself whether the plaster is really still intact. If façades are already older or show visible defects, then it is better to have a professional clean the façade. Laymen can cause even more damage with a high-pressure cleaner. The plaster can crumble or fall off during cleaning. Furthermore, impregnation is recommended after cleaning old façades. Another criterion is the condition of the exterior wall. Care should be taken with silicone and synthetic resin plaster. Cleaning with a high-pressure cleaner can destroy the protective layer. This gives dirt and moss the opportunity to take hold. The same applies to water-repellent facade paint. Here, the professional simply knows better, as you can also see in this video:

Weighing up the costs and benefits of facade cleaning

It is true that do-it-yourselfers can also clean facades. However, there is always a cost-benefit ratio. First you should measure and calculate the areas of the walls. Should it only be on the ground floor or should a multi-storey house be cleaned or freed from moss? Walls on the ground floor can generally be cleaned well by do-it-yourselfers. However, when it comes to multi-storey buildings or large areas, it quickly becomes tricky. As a rule, scaffolding or lifting platforms are needed for this. If you want to do the cleaning yourself, you have to organise all this additionally. Although expenses can be reduced by doing it yourself, this also extends the rental period and rental costs for additional equipment. In addition, the degree of soiling of the facades is also decisive. In the case of heavily soiled facades, home remedies usually cannot do much. Do-it-yourselfers often underestimate the actual effort and ultimately quickly lose patience.


Facade cleaning by do-it-yourselfers is possible in principle. However, it is only possible if the dirt, plaster and façades are uncomplicated and easy to access. If this is not the case, it is better to contact a professional directly.
