Emergency Water Damage in Chicago: how the job actually runs.
Water does not wait for business hours, and in Chicago it has a habit of arriving at the worst possible one. The supply line under the kitchen sink lets go while you are at work. The sump pump stops when the power goes out in the middle of a thunderstorm. The floor drain in the basement starts bubbling at 2 a.m. on a July night. Emergency water damage response is the discipline of getting the water out and the drying started before the 48-hour clock runs out.
What counts as a water damage emergency
If any of these are true, call now rather than in the morning:
- Water is still running and you cannot find or reach the shutoff.
- There is standing water in the basement, especially if the power is still on.
- Water is coming up through a floor drain, toilet or basement shower.
- A ceiling is sagging or holding water, which can come down without warning.
- The water is on the floor of a unit with other units below it.
- Water has reached outlets, the electrical panel, the furnace or the water heater.
A wet room from a burst supply line is an emergency even after the pipe is shut off, because the water is already in the pad, the drywall and the bottom plate.
What happens when you call
The person who answers asks five things: where the water is coming from, whether it is still running, whether the power to that area is off, how deep it is, and what it is on (carpet, hardwood, tile, concrete). The answers set the category and the urgency, and you get instructions for the next ten minutes before a crew is dispatched.
Active water and sewage go to the front of the queue. During a regional storm like July 2, 2023, when up to about 9 inches fell on parts of the West Side, Cicero and Berwyn and thousands of basements flooded, call volume across Chicagoland runs far above normal. We tell you honestly where you are in the line and what to do in the meantime.
The first 24 hours, hour by hour
Hour 0 to 1: you
Stop the source. For a fixture, the shutoff valve under it. For a burst pipe or an unknown source, the main valve, usually in the basement where the service enters the house. For a water heater, the cold feed on top of the tank and the gas or breaker. Cut power to the wet area only if the panel is dry and you are on dry ground. Lift what you can: rugs off carpet, furniture onto blocks, boxes off the floor. Photograph everything before it is moved. The full checklist is in what to do in the first hour after water damage.
Hours 1 to 4: arrival, extraction, mapping
On arrival we confirm the source is stopped, then extract standing water with truck-mount or portable units. Every gallon extracted is a gallon the dehumidifiers do not have to evaporate later. We classify the water under IICRC S500: Category 1 clean supply water, Category 2 gray water from appliances or clean water that has sat, Category 3 black water from sewers, rivers or anything that came through soil. Then we map every wet surface with pin and non-invasive moisture meters and a thermal camera. Water travels sideways along bottom plates and under floor coverings, so the wet area is almost always bigger than the stain.
Hours 4 to 24: drying begins
Air movers and low-grain refrigerant (LGR) dehumidifiers go in the same visit, sized to the evaporation load. Carpet pad that is saturated comes out; Category 1 carpet usually stays and is floated. Baseboard comes off so wall cavities can vent. Drywall wet with gray or black water, or wet more than 48 hours, is cut out above the water line. By the end of day one the loss has stopped growing; see water extraction for the equipment.
Day 2 onward
We come back daily to log temperature, relative humidity, dehumidifier output and material moisture. Typical structural drying is three to five days. Basements and slab floors take five to ten because concrete holds water and the space is cool. The equipment leaves the day the materials reach dry standard, not before and not after. See how long it takes to dry a basement after flooding for the realistic timelines.
Why the first 24 hours decide the price
Two things degrade with time. The first is the water category: clean water that sits for a day or two becomes gray water as it picks up whatever is in the carpet and the dust, and gray water that keeps sitting becomes black. Each step up means more material removed and more sanitizing. The second is mold. Wet drywall paper, carpet pad and framing support growth within 24 to 48 hours in Chicago conditions, faster in the humid months when dew points sit between 65 and 75 degrees Fahrenheit.
A two- or three-room clean-water loss that is extracted and drying by the end of day one usually lands at $2,000 to $6,500. The same loss discovered after a long weekend, now gray water with mold starting on the lower drywall, is a multi-room restoration at $6,500 to $18,000 or more. Speed is the cheapest thing we sell.
Chicago emergencies have seasons
Summer (May to September). Short, intense convective storms overwhelm the combined sewer that serves most of the city and the older inner suburbs, and sewage-laden water backs up through floor drains and basement fixtures. Sump pump failure during a power outage is the other leading cause of basement flooding. Basement flooding cleanup is our busiest work in these months.
Winter. Frozen and burst pipes are the number one winter claim, and the thaw after a deep freeze like the polar vortex of January 30-31, 2019 (about -23 degrees Fahrenheit at O’Hare) is the busiest week of the year for burst-pipe calls. Water heaters and boilers also fail in cold snaps. See frozen and burst pipe water damage.
Spring. River flooding: the region-wide flooding of April 17-18, 2013 along the Des Plaines River, and the Chicago River overtopping downtown in May 2020, which put water into high-rise basements in the Loop and the West Loop.
Any month. Multi-unit water travel. In a Lincoln Park three-flat or an Evanston courtyard building, a burst supply line or an overflowing appliance upstairs runs down through every unit below. The emergency is not one apartment; it is a stack of them.
Insurance and documentation on an emergency
Standard Illinois homeowners policies (HO-3) cover sudden and accidental discharge: burst pipes, water heater failure, appliance supply lines, frozen pipes where reasonable heat was maintained. They exclude surface flooding unless you carry a separate flood policy, and they exclude sewer backup and sump pump overflow unless you added a water backup endorsement, typically with limits of $5,000 to $25,000. Gradual leaks are excluded.
Emergency mitigation is covered when it is documented, so our first visit produces dated photos, a moisture map and a written report, followed by daily drying logs and an itemized scope in the Xactimate format adjusters expect. Where the carrier approves, we bill them directly.
Which emergency is which?
| Source of water | Category | What changes in the response |
|---|---|---|
| Burst supply pipe, water heater, appliance line | 1 (clean) | Extract fast, dry in place, most materials saved |
| Dishwasher or washing machine discharge | 2 (gray) | Antimicrobial treatment, pad removed |
| Clean water left 48 hours or more | 2 (gray) | Treated as gray; wet drywall usually cut |
| Combined sewer backup through floor drain | 3 (black) | Porous materials removed, full sanitization, PPE |
| Sump pump failure in a storm | 2 or 3 | Depends on what came in with the groundwater |
| River or overland flooding | 3 (black) | Removal, sanitization, separate flood policy applies |
What an emergency response costs
Emergency call-out and inspection is $250 to $500 at any hour, and it is credited against the restoration if you proceed. Water extraction is $500 to $2,500. Drying equipment runs $50 to $125 per unit per day, and a typical three-room job uses six to ten units for three to five days. A clean-water restoration across two or three rooms is $2,000 to $6,500; gray or black water through multiple rooms is $6,500 to $18,000 or more. The full breakdown is in our 2026 cost guide.
If you are standing in water anywhere in Chicago or the suburbs, call us or send the form now. We will tell you what to do in the next ten minutes and have a crew on the way.
