Ask who disconnects the sink and fixtures
Ask who disconnects the sink, faucet and any connected fixture before the countertop work. Record whether a separate qualified provider is needed and who arranges that visit. The responsibility belongs in the written project scope.
Confirm what must be ready for stone installation
Request the actual installation preparation checklist. Confirm what must be ready in the kitchen and which work is included in the stone installation. Keep any tasks assigned to you visible in the project notes.
Put reconnection and any outside work in writing
Put reconnection responsibility, timing and any separate charge in writing. Confirm the contact for questions after the stone is installed. Keep plumbing arrangements beside the countertop schedule so each task has an agreed owner.
Keep the next step clear.
Use your checklist to keep open decisions beside the work they affect. Confirm the complete scope and price before booking.
