Quick answer
Servpro sewage cleanup typically runs $2,000–$10,000 for a residential backup, or roughly $7–$12 per square foot of affected area — above standard water damage pricing because sewage is Category 3 water. Nothing porous it touched is dried and kept: carpet, pad, drywall and insulation are removed and disposed of, and every remaining surface is disinfected under containment with HEPA filtration. The spread is driven by affected area, how far it travelled, whether it reached a finished basement, and how long it sat. Sewer backup is excluded from most homeowners policies unless you carry a specific backup rider, so confirm yours before assuming coverage. Call (888) 840-6512 to reach a certified water damage restoration company in your area; the line is answered 24/7.

Ordinary water damage is a drying problem: get the water out, get the moisture out of the materials, keep what can be saved. Sewage is a contamination problem, and the logic runs the other way — what it touched is presumed unsaveable unless it is hard, non-porous and can be disinfected. That reversal is why a sewage estimate from any company, SERVPRO included, reads so differently from a clean-water one, and why the same square footage costs so much more.
Before Anyone Arrives
- 1Keep everyone out. Children and pets first. Sewage carries bacteria, viruses and parasites, and drying does not make it safe; dried residue becomes dust.
- 2Stop using water. Every flush, faucet and appliance in the house may be feeding the backup. Nothing goes down a drain until a plumber has cleared the line.
- 3Cut power to the area. From the main panel, if the panel is somewhere dry. If the water is near the panel, outlets or appliances, stay out and tell the crew when you call.
- 4Photograph before anything moves. From the doorway: depth, extent, what it reached, the point it came from. Your insurer will want this, and so will the utility if the public main turns out to be at fault.
- 5Call a certified crew. And a plumber, in parallel. One deals with what came out; the other with why.
Leave the cleanup itself alone. Household wet vacuums aerosolize what they pick up, and bleach on carpet or drywall does not reach what has soaked in.
What You Are Paying For
| Stage | What happens | Why it costs what it does |
|---|---|---|
| Protection and containment | Crew in respirators and full protective suits; plastic barriers; HEPA air scrubbers running under negative pressure; the HVAC for that area shut off | Labour is slower in protective equipment, and the equipment is consumable |
| Extraction | Pumping and vacuuming liquid and solids into sealed containers | Waste has to be handled and disposed of as contaminated |
| Removal | Carpet, pad, drywall to above the wick line, insulation, baseboards, laminate and vinyl flooring, particleboard cabinetry, upholstered and cardboard contents | The largest line on most estimates. Nothing porous is dried and kept |
| Cleaning and disinfection | Pressure-washing or scrubbing of concrete and framing; an EPA-registered disinfectant applied to every remaining surface; often repeated | Done twice on many jobs — once before drying, once after |
| Structural drying | Air movers and dehumidifiers on what is left, until the framing and slab read dry | Equipment is cleaned and decontaminated after every sewage job |
| Verification | Moisture readings; on some jobs, surface testing to confirm cleaning | Independent testing, where used, is billed separately |
| Reconstruction | New drywall, flooring, trim, paint | Usually a separate estimate, and often half the final cost of the event |
Read your estimate against those rows. Each should be present, and the removal stage should list materials and quantities, not a lump sum.
Why Two Backups the Same Size Cost Differently
- Finish level. Bare concrete basement: mostly cleaning. Finished basement with carpet, drywall and a built-in bar: mostly demolition.
- Time. Drywall and framing wick contaminated water upward by the hour. A backup found after a weekend away reaches further than one caught in an hour.
- Travel. Did it stay in one room, or run under walls into the next? Under a floating floor? Into ductwork in the slab?
- Source. A toilet overflow with solids is handled the same way as a main-line backup, but is usually far smaller. The toilet overflow guide explains where that line falls.
- Contents. A storage basement full of boxes adds a large disposal and inventory job.
- Access and disposal. Walk-out basements are easier than ones reached by a narrow stair; local disposal rules and fees vary.

How Long It Takes
Emergency work — extraction, removal, first disinfection — is commonly one to three days. Drying adds several more. Reconstruction is scheduled afterwards and takes as long as any small renovation. You can usually stay in the house if the affected area can be sealed off and the plumbing is working again; a crew will tell you if not.
Insurance: Check This Before You Call the Adjuster
Standard homeowners policies exclude water that backs up through sewers or drains. Coverage comes from a water backup endorsement that has to have been added before the loss, and it carries its own limit — often $5,000, $10,000 or $25,000 — which a finished basement can exceed. Look at your declarations page first.
Three related points. A blockage inside your own plumbing that overflows a fixture is sometimes treated as ordinary sudden water damage, not as backup; how the cause is described matters, so be accurate and let the plumber's report speak. Flood insurance treats sewer backup as covered only when it is a direct result of a flood. And if the public main was at fault, the utility may be liable, but municipal claim deadlines are short; ask for the form the day you report it. The sewage backup causes guide explains how to tell whose pipe failed.
Checking the Quote
With sewage there is less room for disagreement about method than with clean water — removal of porous materials is the standard, not an upsell. So a second opinion is mostly checking three things: that the quantities are right, that the affected area was measured and not assumed, and that reconstruction is shown separately. The guide to comparing estimates covers the method, and SERVPRO's general water damage pricing is covered on its own page.

Frequently Asked Questions
How much does Servpro charge for sewage cleanup?
Typically $2,000–$10,000 for a residential sewage backup, or about $7–$12 per square foot of affected area. A contained bathroom overflow sits at the low end; a backup through a finished basement runs well above it.
Emergency after-hours mobilisation adds a premium, and disposal of contaminated materials is billed separately from labour.
Why does sewage cleanup cost more than water damage?
Because it is biohazard work, not drying work. Sewage is Category 3 water, carrying pathogens throughout, so the method changes: containment is built, crews work in protective equipment, everything porous the water touched is removed and disposed of rather than dried, surfaces are treated with EPA-registered disinfectants, and the air is filtered through HEPA scrubbers.
The material removal and disposal alone add cost a standard water job never incurs.
Does homeowners insurance cover sewage backup?
Not by default. Sewer and drain backup is a standard exclusion on most homeowners policies and is covered only if you carry a specific backup endorsement — often an inexpensive rider that many homeowners discover they lack at the worst possible moment.
If a covered sudden event caused the backup, some of the resulting damage may still be claimable. Check your declarations page for the endorsement before assuming either way.
What gets thrown away after a sewage backup?
Anything porous the sewage contacted: carpet and pad, unsealed drywall and insulation, particleboard and laminate flooring, upholstered furniture, mattresses, and most soft contents.
Hard, non-porous surfaces — tile, sealed concrete, metal, solid wood — are cleaned and disinfected rather than discarded. Food, medicines and cosmetics that were touched are always disposed of.
How long does sewage cleanup take?
Extraction and disinfection are usually a one to two day job for a contained residential backup; structural drying of what remains runs a further two to four days depending on materials and readings. Reconstruction of what was removed — drywall, flooring — follows separately and is quoted on its own.
How do I check whether a sewage cleanup quote is fair?
Compare it against a second scoped quote, not against a national average. Ask both companies the same four questions: what is being removed versus cleaned, what disinfectant is being used, is HEPA filtration included, and what documentation you receive.
Independent IICRC-certified companies work to the same S500 standard as the franchises, and getting a second number costs a phone call.
Who do I call right now for water damage?
Call (888) 840-6512. The line is answered 24 hours a day, seven days a week, and connects you with an IICRC-certified water damage restoration company that serves your area.
Describe what you can see — where the water is coming from, how long it has been there, and whether it smells — and the dispatcher routes you to a crew that handles that kind of loss. If the source is a pipe or an appliance, shut the main water valve first; the call itself takes under two minutes.
