I am a highly skilled home service professional. I received a request to provide an estimate for hydro jetting service to address a potential blockage or buildup in the kitchen drain line. The customer requested that I access the drain line via the existing clean-out. Before providing a final estimate, I will perform a thorough diagnostic to evaluate the condition of the drain line, determine the severity of any buildup or blockage, and confirm that hydro jetting is the appropriate and effective method for the issue. I will await the customer's approval to schedule the diagnostic, and once completed, I will provide a detailed estimate for hydro jetting.
