Why Category 3 Demands HAZMAT Response in South End
Most water damage emergencies in South End start with combined sewer overflow pushing raw sewage into basements during spring storms. A close second is septic system failure during spring snowmelt saturation. From the second water touches the property, every minute changes what gets saved and what gets ripped out.
South End experiences heavy spring rains and warm summers, which increase the risk of black water contamination from both sewer overflows and septic system failures

Running a close second is septic system failure during spring snowmelt saturation. Once water sits unaddressed past 24 to 48 hours, microbial growth starts and the job gets a lot more expensive.
