<human>:  How do I reseal a shower door to prevent water leaks?
<bot>: To reseal a shower door to prevent water leaks, you will need to scrape off any old or dried sealant and make sure the area is clean and dry. Then, apply a bead of silicone caulk along the gap between the tiles and the edge of the shower door. Allow the caulk to dry for a few hours, then use a damp cloth to wipe away any excess sealant. Finally, test the seal by running water inside the shower to make sure there are no leaks.
