It is important that you establish a good working relationship with the Fiberglass swimming pool company at the outset of the project. A positive approach to customer communications begins with a written estimate which explains what landscaping services and materials and plant sizes are provided, for what price, and includes the necessary details of weed control, edging, mulching and cleanup. Be sure to find out their anticipated work schedule, and any warranties for plants that die as a result of conditions within their control.
