Need to notify certain customers due to stringent insurance requirements for my particular industry. I cannot work work on their tennis court(s) anymore for one or more of the following reasons. 1. Court needs a clay or fast dry lift due to stones and screenings popping through and cause trip hazards especially where lines are installed. 2. Roots popping through surface causing trip hazards. 3. court needs an irrigation system to properly hydrate court and eliminate cracking and trip hazards. We appreciate your business in the past however your courts shelf life is beyond expiration to ensure proper safety and playability. Thank You Richard Piretti (Piretti Tennis Courts.)
