How to Perform Flood + Water Restoration

Why this matters

Water + flood restoration is the highest-revenue + highest-stakes adjacent service to carpet cleaning. A single residential water-damage call is worth many times a routine cleaning ticket, and it runs for days instead of hours. Insurance pays most of it. The skill set is adjacent to carpet cleaning but the protocols + certifications are distinct. This is the working overview.

Water damage categories (IICRC S500)

Category 1 - Clean water:

• Sanitary water at source (broken supply pipe, overflow tub)
• Becomes Cat 2 after 24-48 hours
• Cat 1 if mitigation starts within 24 hours

Category 2 - Grey water:

• Significant contamination (dishwasher overflow, washing machine, urine)
• Can cause illness if ingested
• Becomes Cat 3 after time

Category 3 - Black water:

• Sewage backup, river flood, storm surge
• Pathogens, chemicals, debris
• Requires removal of all porous materials touched

Identify category at first visit. Insurance + customer-side scope differs dramatically.

Class of damage (extent)

Class 1: least water absorption. Under 5 percent of the combined floor, wall and ceiling surface area in the space is wet, and mostly low-porosity materials Class 2: roughly 5 to 40 percent of the combined floor, wall and ceiling surface area is wet Class 3: more than 40 percent of the combined floor, wall and ceiling surface area is wet Class 4: deeply held or bound water in low-evaporation materials (hardwood, plaster, concrete, stone) requiring specialty drying

Pricing scales with class.

Procedure

Step 1: Initial response

Hours after water event matter:

• Within 24 hours: mostly recoverable
• 24-72 hours: mold germination starts
• 72+ hours: extensive remediation often required

Customer often calls 911 (false alarm OR water alarm), then insurance, then service.

1. Inspection + assessment
2. Categorize (Cat 1, 2, 3)
3. Identify class (1-4)
4. Document everything (photo, video, moisture readings)
5. Stop water source (or coordinate with plumber)
6. Initial assessment to customer + insurance

Step 2: Extract standing water

1. Truck-mounted extractor (carpet cleaning extractor adequate for clean water)
2. Pump down to surface level
3. Extract from walls, baseboards, hard surfaces
4. Continue until water no longer flowing

Step 3: Damaged content + carpet removal

For Cat 1:

• Carpet usually salvageable with drying
• Pad usually replaced
• Walls dried in place

For Cat 2:

• Carpet usually salvageable
• Pad always replaced
• Walls dried; cut + replace if heavily affected

For Cat 3 (sewage):

• Carpet + pad REMOVED + disposed
• Drywall 12-24" up removed
• Subfloor inspected + replaced as needed
• All porous materials touched: throw away

Step 4: Dry

Industrial drying equipment:

• Air movers (axial fans): blow air across surfaces for evaporation
• Dehumidifiers: remove moisture from air
• Heat dryers: warm air accelerates evaporation
• Pad drying: special pads with vacuum suction

Setup based on room size + class:

• Class 1: 1-2 air movers, 1 dehumidifier
• Class 2: 4-8 air movers, 2 dehumidifiers
• Class 3: 8-15 air movers, 3-5 dehumidifiers, possibly heat
• Class 4: same as Class 3 plus specialty equipment

Drying time: 2-7 days typical.

Step 5: Monitor + document

Daily visits:

• Moisture meter readings on all surfaces (target: under 16% wood, under specific thresholds for materials)
• Photographs
• Customer signature
• Equipment adjustment

Monitoring documentation is critical for insurance.

Step 6: Remove equipment + final inspection

Once moisture targets met:

• Equipment removed
• Final moisture readings
• Final photographs
• Customer signs completion
• Insurance documentation

Step 7: Reconstruction handoff

After drying:

• Carpet replacement if needed
• Drywall + paint
• Flooring
• Hand off to general contractor or coordinate

Some restoration companies do reconstruction; many subcontract.

Insurance interaction

Most water restoration is insurance-paid:

• Coverage: depends on cause (sudden + accidental vs slow leak vs flood)
• Some causes excluded (flood often separate flood insurance)
• Customer files claim; adjuster visits
• Restoration company provides estimates + photos
• Some insurance assigns benefits directly to restoration company

Best practice: customer assigns benefits to restoration company; we work directly with insurance.

Pricing per Xactimate (industry standard estimating software). Customer-paid uplift on items not covered.

IICRC certifications required

Industry standards:

• WRT (Water Damage Restoration Technician): entry-level
• ASD (Applied Structural Drying): drying specialist
• AMRT (Applied Microbial Remediation Technician): mold-related
• FSRT (Fire + Smoke Restoration): adjacent specialty
• IICRC Master: top-tier

Each is a 16 to 40 hour course plus an exam fee, and each carries annual continuing education to stay current.

For business: at least one tech IICRC-certified per restoration job.

Equipment investment

Restoration equipment:

• Air movers: cheapest item on the list per unit, but you need 6 to 15 for a typical residential loss, so the count is what costs you
• Dehumidifiers: several times an air mover each, and you need 2 to 5. This is the largest line in the kit
• Moisture meters: one pin-type and one non-invasive, both inexpensive relative to the dehumidifiers, and both non-negotiable because they are what the insurance file rests on
• Thermal camera: mid-range item; it finds hidden moisture behind wall surfaces faster than probing does
• Pad drying (floor mat) system: specialty, buy it when hardwood and Class 4 work starts showing up, not before

The dehumidifiers and the air-mover count set the number. Lease or rent for the first few losses and for surge capacity; equipment sitting in the shop between jobs earns nothing.

Common pitfalls

• Wrong category assessment: under-treating Cat 3 = mold + lawsuit
• No documentation: insurance disputes coverage
• No moisture meter readings: customer claims still wet days after equipment removal
• Skipping mold inspection at saturated drywall: contractor finds mold during rebuild
• Inadequate drying time: hidden moisture causes problems later
• Hidden moisture in wall cavities: removed equipment + later mold found
• Customer DIY interim: damp carpet sat for days = mold = much bigger scope

Mold remediation (related)

If mold is found during inspection:

• Stop work
• Contain area
• Recommend mold remediation specialist
• AMRT certification required
• Separate from water restoration scope

Common mistakes to avoid

• Underbidding: lost money + commitment for the job
• Not getting insurance approval before starting: customer pays out of pocket
• No daily monitoring: customer doesn't see progress
• Removing equipment too early: hidden moisture
• No follow-up: customer thinks issue persists
• Wrong restoration scope quoted: customer dispute

Safety considerations

Water restoration safety:

• PPE for Cat 2 + 3 work: respirator, gloves, eye protection, dispose disposable clothing
• Electrical safety (water + electricity)
• Biohazard for Cat 3 (pathogens; disposal protocols)
• Customer + family relocation during heavy work
• Sharps + nails + screws in dried-out subfloor

Customer talking points

For first visit:

1. "Water category , extent class [Y]"
2. "Drying time [Z days]; we monitor daily"
3. "Likely scope: [estimate]"
4. "Insurance: we work with [their carrier]; assign benefits to us"
5. "Once dry, hand off to [reconstruction] OR we coordinate"

For day-2 monitoring:

1. "Moisture readings today: [readings]"
2. "Progress: [report]"
3. "Adjustments: [equipment changes]"

For final visit:

1. "Every material is back to the dry standard. Here are today's readings next to the readings from the unaffected area we've been comparing against."
2. "Here is the full log: readings by day, by location, and where equipment sat each day."
3. "This is what we removed and why, and this is what we saved."
4. "Equipment comes out today. Here's the count and the run days, which is the line you'll see on the invoice."
5. "What's left is reconstruction, not drying. That's [carpet reinstall / pad / baseboard / drywall], handled by [us / the contractor you choose]."
6. "Watch for these in the next few weeks: any musty odor, any new staining on the baseboard or ceiling below, any buckling. Call us if you see any of them, don't wait for the next scheduled visit."
7. "Your adjuster gets the readings log, the photos, the moisture map, and the equipment record from us. You'll get the same packet."
8. Get the completion sign-off in hand before the truck leaves. A signature after the customer has seen the final readings is the document that closes the file.
