While the life of a tennis court can be estimated at around 20 years, a number of courts built by Siméon have exceeded the 25-year mark. Some of them only require an intervention to refresh the surface paint and revise the fencing.

Of course, Siméon courts can renovate any kind of surface: porous concrete, hot or cold coatings, traditional or artificial clay, tufted carpet, etc. Renovation generally takes around two or three weeks without damaging the fencing if the latter is in a good state.

Siméon courts follow up their clientele and every year look after the annual revamp of traditional clay courts in clubs and at private venues.
