What it usually means

Sewage backing up into the house is both a health hazard and a warning about the main line — plunging one drain won't touch it, because the problem sits downstream of every fixture.

Act now — this one damages the home while it waits. Stop running water anywhere in the house — every flush and sink adds to what's backing up. Keep people and pets away from the sewage and wear protection during any cleanup; it carries real health risks.

Common causes:

• Tree roots invading the sewer lateral through pipe joints — a leading cause in older Florida neighborhoods

• A grease and debris mass built up over years until the line finally chokes

• A collapsed or bellied section of aging cast-iron or clay pipe holding waste back

• A blockage or overload in the municipal main, which is the utility's responsibility rather than yours

Red flags when hiring

• An immediate dig-and-replace quote before a camera has actually shown the cause and location

• No offer to camera the line — the only way to know if it's roots, grease, or a broken pipe

• Anyone who ignores whether the blockage might be on the city's side of the connection

• No state license number for plumbing work

Quick answers

How do I know if it's my sewer line or the city's?

If multiple drains back up and a cleanout check shows the blockage past your property line, it may be the municipal main — the utility's responsibility. A plumber's camera inspection settles where the problem actually sits.

Is sewage backup covered by insurance?

Standard homeowner policies often exclude sewer backup unless you carry a specific backup endorsement. Check your policy before you need it, and document everything if a backup happens.

What this usually costs in Florida

Main sewer line clearing: $250–$1,100 (typical ~$500)

Cable-clearing a main line; a camera inspection and any dig-and-replace are separate.

Licensing & permits in Florida

Florida licenses this trade at the STATE level (DBPR / CILB (CFC)). Hiring unlicensed for this work is illegal for the contractor — and risky for you: no permit rights, no insurance backing, no recourse.

Work like this often requires a county permit — a legitimate pro pulls it, not you.

Basis: FL Stat. 489 (DBPR state licensing).
