The length of time required for tennis court construction depends heavily on the type of court being constructed. There are three main types of tennis courts: clay courts, grass courts, and concrete courts. As for grass tennis courts, the construction time depends on whether or not you already have suitable grass to build the court on. If the grass is already there, then construction of a grass tennis court need not take very long. However, if you need to grow the grass for your tennis court, then this type of court can take quite awhile to construct. Concrete court construction time is limited by the amount of time necessary to prepare the land for the concrete to be poured as well as the length of time it takes the concrete to cure after it is poured. Depending on who you hire and how long they work daily, concrete court construction can a few weeks. Weather can impact the length of time necessary to construct all types of tennis courts.
