Water leak at home

Water is coming in or pooling. Stop the source, protect what you can, then repair.

Act carefully and stop if anything feels unsafe. When in doubt, call a professional.

Water damage gets worse by the minute. Shutting off the supply is almost always the first move, ahead of finding the exact cause.
