Red flags in cheap bids
- No camera footage or photos before quoting a fix — if it isn't documented, you're buying a guess
- "We don't need to inspect first" for anything beyond a simple clear — structural damage needs a camera pass
- Pressure to sign for full excavation before a trenchless option is even discussed
- Door-knockers right after a storm with no fixed local address — verify local presence first
Common questions
ResponsibilityIs the sewer line my responsibility or the city's?
In almost every jurisdiction, you own and maintain the lateral from your house to the property line or the main connection point — the city or utility is typically only responsible for the main line under the street. A camera inspection shows exactly where a problem sits relative to that line.
DiagnosisWhy does every quote start with a camera inspection?
Because a sewer line is invisible until it isn't. Root intrusion, a bellied (sagging) section, and a fully collapsed pipe all cause the same symptoms above ground but need completely different repairs — camera footage is the only way to quote the actual fix instead of the worst-case one.
MethodTrenchless repair or dig it up — how is that decided?
CIPP lining and pipe bursting both work inside the existing pipe path and typically need only small access pits, saving the lawn, driveway, or hardscaping above. Severely misaligned, crushed, or bellied sections usually still need open excavation — the camera inspection tells you which situation you're in.
InsuranceDoes insurance cover a sewer line backup?
Standard homeowners and property policies typically exclude sewer and drain backups unless you've added a specific sewer-backup or water-backup endorsement. Check your policy's endorsement list before assuming coverage either way.
PricingWhy is there such a wide range?
Scope drives cost: how much of the line is affected, how severe the blockage or damage is, and whether trenchless repair or excavation is needed. That's why every job starts with a free camera inspection — you get a real number for your situation, not a guess.
InsuranceWill insurance pay for this?
Check your policy's endorsement list — overland-water & sewer-backup endorsements — before assuming coverage either way. We provide the documentation carriers require if a claim applies.
