Terrace Washing — Professional Terrace Cleaning

Regular terrace washing is an important part of terrace maintenance. Dirt, moss and algae accumulate on the terrace surface, especially in spring and autumn when moisture and temperature fluctuations are at their highest. A dirty terrace is not only unsightly but also slippery and dangerous to walk on.

Washing a wooden terrace before oiling is essential so that the oil is absorbed evenly and adheres properly. Washing removes old oil residue, dirt and the greyed surface layer. When done correctly, washing restores the wood's original colour and prepares the surface for protective treatment.

Cleaning composite terraces is simpler but equally necessary. Composite does not require oiling, but regular washing prevents moss and algae growth and keeps the terrace clean and safe to use throughout the entire summer season.

A professional selects the washing method based on the terrace material and condition. A pressure washer is an effective way to remove ingrained dirt and moss, but its use requires expertise. Too much pressure can damage the wood surface and raise the grain, making the surface rough and uneven.

Chemical washing is particularly suitable for cleaning delicate wood species and composite terraces. Eco-friendly cleaning agents effectively loosen dirt and moss without mechanical stress. The cleaning agent is applied to the terrace surface, left to work and then rinsed off with water.

A professional knows how to combine different methods for the best result. For example, chemical pre-treatment combined with gentle pressure washing produces an excellent result without damaging the surface. Washing is best scheduled for spring before the terrace season begins.

The price of terrace washing depends on the size, material and level of soiling of the terrace. Washing a small terrace starts from around €150, while thorough cleaning of a larger terrace can cost €300–500. The price usually includes cleaning agents and equipment use.

Combined services, such as washing and oiling at the same time, are often more affordable than separate orders. Many professionals offer package prices that include terrace washing, drying time and protective treatment as a complete service at a competitive price.

The price is also affected by the accessibility of the terrace and any special requirements. Hard-to-reach terraces or particularly soiled surfaces may increase the price. Always request a quote in advance and ask what is included in the price to avoid surprises.

You can maintain your terrace condition with simple measures. Regularly sweep leaves and debris from the terrace, as damp organic matter promotes moss and mould growth. Make sure water can drain off the terrace and does not pool on the boards.

A light wash with a garden hose and brush a few times during summer is enough to keep the terrace clean. A more thorough professional wash should be done once a year in spring before the terrace season begins, and if necessary in autumn at the end of the season.

Place plants and pots on stands so that water does not pool on the terrace surface underneath them. Place pads under furniture to prevent scratches and moisture build-up. These small measures will significantly extend the lifespan of your terrace.
