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.
Whether you live in San Francisco, Sacramento, Oakland, Los Angeles or San Diego, our certified basement and crawl space contractors in your local areas are ready to help you find the right solutions to your basement or crawl space problems. They offer FREE basement or crawl space Estimates and Inspections!
Your home in California may face many types of basement or crawl space water problems, but we've seen them all! In our experiences we've found that the patented WaterGuard basement waterproofing system is the perfect solution for a wet basement, and our sump pumps are the best.

Comment: We contracted with a local licensed contractor and he built us a home that we moved into March 2016. He failed to install drains under the raised sub floor and we had a tremendous amount of flooding from the 60" inches of rain we received this last winter season. We are in the process of resolving this issue. Thank you.
