Does Comcast come to my home to mark buried cable...

Good morning!, @user_e591yl Thank you for reaching out. To clarify, Xfinity does not typically come to your home directly to mark underground cable lines upon request. Before any digging project, you'll need to contact 811 (Call Before You Dig), a free nationwide service. When you submit a request, 811 notifies the utility companies in your area, and the appropriate providers, including Xfinity when applicable, will arrange to have their underground lines located and marked. Utility owners are required to respond to 811 locate requests before excavation begins.
