No one cares how to deal with the seepage in the garage of the building.

1. First, the garage was found to be leaking. You can try to clean up stagnant water with water-absorbing equipment, mops or other water-absorbing tools to avoid flooding affecting vehicles or other property.

2. Secondly, the garage belongs to a management organization, such as a property management company or an owners' committee. You can try to contact and reflect the problem to them. Provide detailed descriptions and related photos or evidence to speed up the process of solving problems.

3. Then, if the property or owners' committee can't solve it, you can contact the local construction management department or urban planning department to reflect the water seepage problem to them. Relevant personnel will be sent to investigate and urge the responsible party to take necessary measures to solve the problem.

Finally, if the problem persists and causes serious impact or damage, you can seek legal aid, consult relevant legal professionals, understand the rights and interests and feasible legal channels, and seek more specific solutions.
