Emergency FAQ
What counts as a cast iron sewer emergency?
Sewage backing up into the home, wastewater pooling indoors, strong sewer gas, or active leaking that threatens electrical systems or structure should be treated as emergency conditions.
How much does emergency sewer service cost?
Emergency dispatch and immediate stabilization often ranges from $850 to $4,500+, depending on timing, severity, and whether excavation access is required. Full replacement costs are quoted after inspection.
Should I use drain cleaner during an emergency backup?
No. Chemical cleaners can make conditions more dangerous and may worsen already damaged cast iron. Stop water usage and call emergency service instead.
Can I stay in my home during sewer backup cleanup?
It depends on contamination level. Small isolated events may be manageable, but widespread backup often requires temporary relocation until sanitation and drying are complete.
Will insurance cover emergency cast iron sewer damage?
Policies vary. Many do not cover age-related pipe replacement but may cover resulting water damage from sudden events. Document everything and contact your insurer immediately.
What should I ask emergency plumbers before approving work?
Ask for camera confirmation, exact failure location, immediate stabilization plan, pricing breakdown, restoration assumptions, and whether temporary fixes are included or billed separately.
