In most instances when installing a new service line, it is the customer’s responsibility to restore the sidewalk. However, in those cases where the sidewalk is disturbed and it is UGI’s responsibility to make final restoration, UGI will immediately backfill it with sand and stone to avoid any safety hazards. Then we need to wait a minimum of 90 days to allow for the settlement of the materials before restoration of the sidewalk. Paving is also seasonal and cannot be completed in the late fall/winter months. Repaving can take three months to a year.
