Water coming up through a floor drain is not covered the way the rest of the policy is covered. Nearly every standard Illinois homeowners and commercial property form excludes water that backs up through sewers or drains, or that overflows from a sump — and then sells the coverage back as an endorsement, usually named something close to water backup and sump discharge or overflow. If that endorsement was added to the policy, there is a claim. If it was never added, the same loss produces nothing, which is why the first thing worth doing after a backup is reading the declarations page rather than calling to argue about the damage.
The endorsement is the part that surprises people. It does not restore the dwelling limit for this cause of loss; it grants a separate, much smaller one, and the figures commonly written on Illinois policies sit in the low thousands to low tens of thousands. It is usually a single combined limit, which is the detail that decides the outcome: the structure, the contents and the cleanup all draw down the same number. A finished basement can exhaust the whole endorsement on demolition and remediation alone and leave nothing for the drywall, the flooring, the furnace or anything that was stored down there. A loss that would be routine under the main policy becomes an arithmetic problem about which parts of the claim get paid.
That arithmetic is the reason a backup claim has to be assembled in a particular order, and quickly. Sewage is Category 3 water, so the mitigation crew is obliged to remove the porous materials it touched, and they will begin doing it within a day or two — carpet, pad, drywall to a line above the water mark, insulation, and everything stored on the floor. Once that material is in the dumpster it cannot be inspected, photographed or inventoried, and a contents list written from memory three weeks later is worth very little against an adjuster who was never in the room. We document the height of the water on every wall, the extent of the affected assemblies and the contents item by item before remediation begins, establish what actually failed, and then work out which coverages the loss touches — because a backup rarely touches only the endorsement.
What the damage looks like
- Water rising through floor drains, a shower pan or a basement toilet rather than entering from outside
- Several fixtures on the lowest level backing up at once, or gurgling when an upstairs fixture drains
- A sewage odor and visibly contaminated water — grey or black, often with solids
- A sump pit that overflowed during a storm, or a pump that ran continuously and then stopped
- A water line on the foundation walls and swollen particleboard on the bottom of base cabinets and shelving units
- Backups that repeat in heavy rain, which points at the municipal main or at roof and foundation drains tied into the sanitary line
What carriers routinely leave out
- The endorsement limit itself — reading it before the scope is written changes which parts of the claim to document hardest, and finding out afterwards means the decision was made for you
- Contents, which in a basement are frequently the larger half of the loss and are almost always the part disposed of first
- Ordinance or law coverage: when the village requires a backwater valve or an upgraded sump on the rebuild, that is a separate coverage line from the backup endorsement and it has its own limit
- Category 3 protocol priced as ordinary drying — disinfection, antimicrobial application, controlled removal and post-remediation verification are not the same scope as running fans
- The furnace, water heater, electrical panel and any ductwork that ran below the water line, which are commonly left out of a scope written around finishes
- A separate claim against the municipality where a main surcharged, which runs on its own track and its own deadlines and belongs to a lawyer rather than to a public adjuster
Every item on this list is money. Our job is making sure each one is documented, valued and in the claim.
State Adjusting Services is hands down the best company I’ve partnered with in the Chicagoland area as a public adjuster. Thanks to their exceptional work, nearly all of my clients have received new roofs, gutters, downspouts, garage doors, and even new floors due to water damage. Their team is not only highly professional but also genuinely cares about each client. I highly recommend them!
Sewer Backup questions, answered
My policy has no water backup endorsement. Is there anything left to claim?
Sometimes, and it is worth checking before accepting the answer. The exclusion applies to water arriving through the sewer or the drain. If a supply line let go during the same storm, if a sump failed for a covered reason your form treats separately, or if the water reached the building by more than one path, parts of the loss can sit on coverage lines the exclusion does not reach. It is a question of establishing what physically happened, which is why the cause is worth determining even when the first answer sounded final.
How much does the endorsement actually pay?
It pays up to whatever figure appears on the declarations page for that endorsement, and that figure is generally far below the dwelling limit — commonly in the low thousands to low tens of thousands on Illinois policies. Read it as a single combined number covering structure, contents and cleanup together unless the form says otherwise. Nobody can tell you what your settlement will be without reading your policy and measuring your loss, but knowing the cap on day one tells you how the claim has to be built.
The mitigation company is hauling everything out tomorrow. What has to happen first?
Let them mitigate — sewage is a health matter and the policy requires you to prevent further damage — but get the evidence recorded first, because this is the one window that does not reopen. Photograph and video every room with the water still present and the water line visible on the walls. Inventory the contents where they sit, with makes, models and photographs, rather than after they are on the driveway. Get the moisture readings and the water category recorded in writing, and keep the remediation invoice and the disposal manifest.
The village says the main surcharged in the storm. Does that help my claim?
It helps establish the cause, and the cause is what decides which coverage applies, so it belongs in the file along with any municipal record of the event. Whether the municipality itself owes you anything is a separate matter from the insurance claim, runs on its own timetable, and is a question for a lawyer — we handle the claim against the carrier and stay in our lane on the rest.
The carrier approved drying and cleaning but not the drywall and flooring. Is that normal?
It is common on backup claims and it is usually worth answering. Category 3 water contaminates the porous materials it contacts, and the accepted remediation standard is removal rather than drying in place — drywall taken back above the water line, carpet and pad discarded, insulation removed. An estimate that dries and cleans a basement a sewage backup reached is describing a different loss than the one that happened, and the documentation taken before demolition is what settles the disagreement.
