What Makes Oakland See Category 3 Events
Living in Oakland means dealing with aging combined sewer overflow during nor'easter and heavy rain events sooner or later. A close second is frozen and burst sewer laterals releasing contaminated water. The good news: water damage is fully recoverable when you catch it fast and bring in certified technicians.
Oakland experiences cold winters and heavy spring rains, which increase the risk of sewer backups and black water contamination. The region's climate also contributes to frozen pipes and thaw-related flooding.
Most category 3 black water cleanup calls in Oakland come from aging combined sewer overflow during nor'easter and heavy rain events. Running a close second is frozen and burst sewer laterals releasing contaminated water. Once water sits unaddressed past 24 to 48 hours, microbial growth starts and the job gets a lot more expensive.
