Before arrival
Make sure the people handling the removal know what is leaving and what access is available. Confirm which connections or fittings must be addressed before they arrive.
At the property
Have the person authorized to approve the work available. Point out fragile surfaces, steps, access restrictions and any changes since the estimate. Keep children and pets away from the working route.
Questions about the work
Ask who is responsible for collection, utility disconnection and any separate installation work. Agree on changes to the scope before work proceeds.
