Tennis Court Maintenance Guidelines

How are the courts prepared?

At the start of the season (early/mid April, depending on weather condition), an external company comes and replaces the top layer of the clay. This new clay is flattened by rolling and watering regularly. It costs about CHF 16‘000 per year.


Why do we water the courts?

Watering helps settle and stabilize the clay. If it is not watered, it turns to dust and blows away? The courts are being watered during the day when the weather is hot and even before every match. During night an automatic sprinkler system is watering the courts several times.


Do we water the courts when its raining?



If the courts are wet can you play on them?

Not if they are really wet or there are pools of water. Your feet marks will damage the courts and they will have to be rolled again, which is expensive. Any marks where clay is moved should be filled in again by rubbing across with your foot before brushing the court.


Why do we brush the whole court?

We should brush all around the court and especially the sides and backs, all the way to the fence. In between the courts you will see grass and weeds growing. They grow because people don’t brush after playing and the weeds can set root. It doesn’t look nice and it spreads faster once they have established a patch.


Brush or mat?

At the start of the season use a mat, because the surface is still settling. Tony will use a brush at the end of the day to flatten the courts. Towards the end of the season use a brush or mat, whichever you like.


Which direction do I brush?

The new thinking is that we should vary the way we brush the courts, because this disperses the clay more evenly. In a circular motion one day, up and down the next and across and back the day after. See how many different ways you can invent.
