 Your Home faces Water Damage

1. California may not receive a lot of precipitation on average but you would be surprised that California flood insurance loss from 1978 to 2001 was over 350 million dollars. That is the ninth highest in the nation.

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.
