Water Damage Lansing is a water damage restoration company that provides sewage backup cleanup in Lansing, MI and the Greater Lansing area. A sewer backup is the most common reason a Lansing basement ends up with contaminated water in it: in a heavy storm, older parts of the city's sewer system overload and push water back up through the lowest drain in the house. Under the IICRC S500 standard that's Category 3 (black) water, and it's cleaned up differently from a burst pipe.

## What we do on the first visit

We confirm it's a backup — water came up through a floor drain, shower, or toilet — and whether it's still rising. We tell you what to stop using (toilets, washer, sinks) until the line clears. Then we photograph everything **before** cleanup starts, because both your insurer and any claim against the city need the evidence.

Because this is Category 3 water, the scope includes removing contaminated porous materials, not drying them. You get that scope in writing before work starts.

## Why Lansing sewers back up into basements

Parts of Lansing still run on a **combined sewer** — one pipe carrying both sewage and storm water. The city is spending about $250 million between 2020 and 2035 to separate it, under a consent order with Michigan's environmental agency. Until your area is separated, a heavy storm can fill the line faster than it drains, and the overflow goes to the lowest opening: your basement floor drain.

Backups also happen on separated systems — a blocked private lateral, tree roots, or a collapsed pipe. That distinction matters: the city is only potentially responsible when the public sewer caused it.

## What gets removed and what gets cleaned

IICRC S500 treats porous materials contaminated by Category 3 water as unsalvageable. That means **carpet and pad, drywall and insulation** the water touched (plus a margin above the wet line), and porous stored items like cardboard, upholstered furniture, and mattresses. Concrete, block, tile, and sound framing are cleaned, disinfected, and dried. Crews work in protective gear and the area is kept separate from the rest of the house.

Please don't mop it and bleach it yourself. Bleach doesn't reach contamination inside porous materials, and sewage carries bacteria and viruses you don't want on your hands or tracked upstairs.

## Insurance, the 45-day claim, and the city program

A standard Michigan homeowners policy **excludes sewer and drain backup** unless you bought a water backup endorsement, usually $75–$150 a year for $5,000–$25,000 of coverage. See [sewer backup insurance in Michigan](https://waterdamagelansing.com/guide/sewer-backup-endorsement-michigan/).

If the public sewer caused it, Michigan law (MCL 691.1416–.1419) allows a claim against the city or utility — filed **in writing within 45 days** of discovering the damage. The City of Lansing also reimburses property owners inside city limits for a backflow valve installed by a licensed plumber, up to $4,750. See [the 45-day claim](https://waterdamagelansing.com/guide/michigan-sewer-backup-claim-45-days/) and [the Basement Backup Protection Program](https://waterdamagelansing.com/guide/lansing-basement-backup-protection-program/).

## FAQ

**How much does sewage backup cleanup cost in Lansing?**

Published Lansing rates put Category 3 work at $7.50–$11.25 per square foot, with a typical minimum of $3,500–$6,000. M&M Restoration cites $2,000–$10,000+ across Mid-Michigan, averaging $3,500–$5,000. Finished basements cost more because more material comes out.

**Is sewage backup water dangerous?**

Yes. Sewage carries bacteria, viruses, and parasites. Keep children and pets away, don't touch it bare-handed, and throw out food or medicine it reached. Porous items it soaked can't be reliably disinfected.

**Will the city pay for my sewer backup?**

Only if the public sewer caused it and you file a written claim within 45 days of discovery, per MCL 691.1416–.1419. The city can deny it if the backup came from your private line. Photos and our cleanup records help either way.

**How do I stop it happening again?**

A backwater (backflow) valve on the sewer line is the main fix. Lansing's Basement Backup Protection Program reimburses the first $1,000 plus 75% of the next $5,000, up to $4,750, for property owners inside Lansing city limits.
