What causes a sewage backup
A backup usually traces back to a clogged mainline, tree root intrusion, aging cast-iron laterals — common in older Brockton housing stock, including triple-deckers and pre-war homes — municipal line issues, or heavy rain overwhelming the system. Whatever the cause, standing sewage in a living space is an active health hazard, not a maintenance item to schedule around.
What to do in the first hour
Stop using water and plumbing anywhere in the home. Keep people and pets out of the affected area. Don’t attempt to wet-vac or mop black water yourself, and ventilate the space if it’s safe to do so. Call immediately, and if it’s safe, photograph the damage before cleanup starts — that documentation matters for your insurance claim.
Why DIY is dangerous
Raw sewage carries pathogens including E. coli, hepatitis A, and parasites that make direct contact and inadequate cleanup genuinely dangerous. Household tools used on black water can cross-contaminate unaffected parts of the home, and incomplete extraction leaves hidden moisture behind — mold can begin developing within 24 to 48 hours in wet conditions.
Our sewage backup cleanup process
We assess the affected area, contain it to stop the spread, extract standing sewage with equipment rated for black water, and remove and discard unsalvageable porous materials — carpet, drywall, and insulation that contacted contamination. Every affected hard surface is disinfected with EPA-registered products, the structure is dried and dehumidified, and we document everything for your insurance claim.
Insurance claim assistance
Category 3 backup damage is often covered under homeowner’s or renter’s insurance, though coverage varies by cause and policy. We document the damage thoroughly — photos, moisture readings, and an inventory of affected materials — to support your claim. We don’t provide legal or insurance advice; confirm coverage specifics with your carrier.
