Grey Water Damage in Cicero: Category 2 Cleanup Steps

water damaged based with actve leak

It usually starts small. A dishwasher hose splits open in the middle of dinner, a washing machine overflows during a Saturday load, or the sump pump quits during a Cicero thunderstorm and your finished basement starts taking on water that smells faintly of detergent and dirt. That water is not the clean kind from a supply line, and it is not raw sewage either. It sits in the middle, and the industry has a name for it: Category 2, or grey water. Knowing which category you are dealing with changes everything about how the cleanup needs to happen, what your insurance company expects, and how much risk your family or tenants are absorbing every hour the water sits there.

At Cicero Water Restoration, we have been responding to grey water calls across central Indiana since 2018, and the honest truth is that most homeowners do not realize a Category 2 loss can turn into a Category 3 in roughly 48 hours if nothing is done. That is not a sales line. That is the IICRC S500 standard we are certified to follow. This guide walks you through what grey water actually is, what the cleanup looks like step by step, what it tends to cost in Cicero, and when you genuinely need a professional crew on site rather than a wet vac from the garage.

Step 1: Stop the Source (0 to 5 Minutes)

  1. Shut the local supply valve. For dishwashers, the valve is under the sink. For washing machines, behind the unit (hot and cold).
  2. If you cannot isolate locally, close the main shutoff. In most Cicero homes this is in the basement near the front foundation wall or in a utility closet.
  3. Kill power to the affected circuit at the breaker panel. Do not stand in standing water to reach a panel.
  4. Photograph the source, the valve position, and the surrounding area from four angles before touching anything else.
  5. If the source is a supply line failure, cap the line with a SharkBite or compression cap before reopening any upstream valves.

Step 2: PPE and Safe Entry (5 to 10 Minutes)

  1. Nitrile gloves, minimum 5 mil thickness.
  2. Rubber boots or shoe covers rated for liquid contact.
  3. N95 respirator if the water has been sitting more than 12 hours.
  4. Safety glasses if overhead drywall is sagging or dripping.
  5. Do not let children or pets enter the affected zone until extraction is complete.
  6. Tyvek coveralls if you will be cutting or removing wet drywall, since the inner face often holds higher bacterial counts than the surface water.

Step 6: Structural Drying Setup (Hours 4 to 8)

  1. One air mover per 50 to 60 square feet of affected wall and floor surface, angled at 15 to 45 degrees.
  2. One LGR dehumidifier per 1,000 to 1,500 cubic feet of affected space. Low Grain Refrigerant units pull 12 to 30 gallons per day in Cicero's humidity range.
  3. Target ambient: 70 to 90 degrees F, relative humidity under 40%, specific humidity under 55 grains per pound.
  4. If subfloor or wall cavity moisture exceeds 20%, drill weep holes or remove baseboards to vent the cavity.
  5. Affected hardwood gets mat drying systems with negative-pressure manifolds. Detailed protocols for floor salvage decisions are covered in our hardwood floor water damage guide.
  6. Contain the drying chamber with 6 mil poly walls when adjacent unaffected rooms are climate controlled. Containment reduces dehumidifier load by 30 to 50%.

Step 9: Final Clearance and Documentation

  1. Final moisture map showing all readings at or below dry standard.
  2. Before, during, and after photos for every affected room.
  3. Equipment log: serial numbers, run hours, daily readings.
  4. Itemized invoice mapped to Xactimate line items for your adjuster. See our complete price breakdown for typical line-item ranges.
  5. Antimicrobial product SDS sheets included in the file.
  6. Certificate of completion signed by the lead technician and the homeowner, with a notation that the structure meets the S500 dry standard.

Step 3: Categorize and Document (10 to 30 Minutes)

  1. Confirm Category 2 classification by source. Grey water sources include appliance discharge, shower runoff, and clean toilet overflows.
  2. If the water passed through ceiling insulation, sat over 48 hours, or contacted any sewage line, reclassify as Category 3 and call professional sewage cleanup immediately.
  3. Measure affected square footage. Note flooring type, wall type, and whether water migrated under cabinets or baseboards.
  4. Record water depth at the deepest point. Photograph a ruler in the water.
  5. Start a contents inventory: anything porous touched by grey water (upholstery, mattresses, paper, particleboard) is generally non-salvageable under S500.
  6. Note Class designation as well. Class 1 affects part of a room with minimal absorption, Class 2 saturates an entire room and wicks up walls under 24 inches, Class 3 involves overhead saturation, and Class 4 includes deeply held materials like hardwood, plaster, and masonry.

Step 7: Daily Monitoring (Days 1 to 4)

  1. Moisture readings logged every 24 hours on a drying chamber map.
  2. Targets: framing lumber under 16%, drywall under 1% on a pinless meter, concrete under 4%.
  3. Equipment is repositioned, added, or removed based on readings, not on a fixed schedule.
  4. Most Category 2 losses in Cicero reach dry standard within 3 to 5 days.
  5. Record temperature, RH, and GPP at three points: inside the chamber, outside the chamber, and at the dehumidifier exhaust. A working LGR should exhaust 15 to 20 degrees F warmer than ambient.

Typical Cicero Pricing Ranges

  1. Small Category 2 loss (one room, under 200 sq ft): $1,500 to $3,500.
  2. Mid-size loss (multiple rooms, 200 to 600 sq ft): $3,500 to $8,000.
  3. Large loss with demolition (over 600 sq ft or multiple floors): $8,000 to $18,000.
  4. Most homeowner policies cover sudden-discharge grey water events. Gradual leaks (over 14 days) are commonly excluded.
  5. Cicero Water Restoration bills direct to most major carriers and provides Xactimate-compatible documentation with every file.

Step 10: Post-Mitigation Verification

  1. Schedule a 30-day follow-up inspection to confirm no secondary microbial growth has developed inside repaired wall cavities.
  2. Use a borescope through a small inspection hole at the base plate if any odor returns.
  3. Verify HVAC operation. Run the system for 15 minutes and check supply registers for musty odor or particulate discharge.
  4. Confirm reconstruction does not begin until written clearance is issued. Closing walls over damp framing is the most common cause of mold claims six to twelve months after a loss.

Step 5: Antimicrobial Application (Same Day as Extraction)

  1. EPA-registered antimicrobial applied to all affected surfaces at label dilution.
  2. Dwell time: minimum 10 minutes before drying equipment runs.
  3. Wall cavities are treated through small inspection holes drilled at the base plate, 12 to 16 inches on center.
  4. HVAC supply and return registers in the affected zone are sealed with 6 mil poly until duct inspection is complete.
  5. Cicero Water Restoration technicians log product name, EPA registration number, dilution ratio, and square footage treated on the job file.

Step 4: Extraction (30 Minutes to 4 Hours)

  1. Truck-mounted or portable extractors pull standing water at rates of 8 to 25 gallons per minute depending on equipment.
  2. Target: zero standing water and surface moisture content under 16% on wood, under 1% on concrete before drying equipment is staged.
  3. Carpet over Category 2 water is typically removed. Pad is always removed. The S500 standard allows carpet to be cleaned and reinstalled only if it is structurally sound and decontaminated within 24 hours.
  4. Sub-floor wood is extracted with weighted wand attachments to pull water from the seams.
  5. Document extracted volume. A 200 square foot loss with one inch of standing water yields roughly 125 gallons.
  6. For multi-room losses, extract from the perimeter inward to prevent pushing water into previously dry areas.

Step 8: Demolition Decisions

  1. Drywall: cut 12 to 24 inches above the waterline if cavity insulation is wet. Flood cuts are documented and photographed before removal.
  2. Insulation: fiberglass batts that wicked grey water are removed and bagged.
  3. Cabinets: kick plates removed for inspection. Particleboard bases that swelled past 2% expansion are replaced.
  4. Baseboards and shoe molding are pulled before drying to vent wall cavities.
  5. Engineered flooring with delamination at the seams is removed. Solid hardwood with cupping under 1/8 inch over 6 inches can often be sanded and refinished after drying.

Frequently Asked Questions

Is grey water dangerous to touch?

Yes. Category 2 water contains bacteria, chemicals, or biological contaminants that can cause skin irritation, infection, or illness if ingested or inhaled. Cicero Water Restoration crews in Cicero wear N95 respirators and nitrile gloves on every Category 2 job for this reason.

How fast does Category 2 water become Category 3?

Typically 48 to 72 hours at room temperature, faster in warm humid conditions common in Cicero basements during summer. Once it crosses into Category 3, cleanup costs roughly double and material removal becomes much more aggressive.

Will my homeowners insurance cover Category 2 cleanup?

Most standard policies cover sudden accidental discharges like a burst washer hose or dishwasher failure. Gradual leaks and groundwater seepage usually are not covered without specific endorsements. Cicero Water Restoration provides the documentation your Cicero adjuster needs to process the claim.

Can I clean Category 2 water myself?

Very small contained spills on hard non-porous surfaces can sometimes be handled with proper PPE and disinfectant. Anything affecting carpet, drywall, subfloor, or more than about 10 square feet should be professionally mitigated to avoid mold and structural problems.

How long does Category 2 cleanup take in a typical Cicero home?

Most residential Category 2 losses take 3 to 5 days of active drying after extraction, plus any reconstruction. Cicero Water Restoration monitors moisture daily and pulls equipment only when materials hit dry standard, usually 14 to 16 percent in wood and under 1 percent moisture content in drywall.
