Abstract: Methods, systems, and devices for sealing stage tool leaks are disclosed. In one aspect a stage tool for wellbore cementing comprises an external stage tool body and a sliding sleeve within the external stage tool body configured to regulate cement flow through the stage tool. At least a portion of the sliding sleeve comprises a meltable alloy configured to seal a leak. The meltable alloy is configured to be melted by a heating source, flow into the leak, and resolidify as the melted alloy cools, thereby sealing the leak.
