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 generates in scope vs for routine cleaning. 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: small spot, minimum absorbance, limited drying needed Class 2: significant moisture, entire room carpet + walls 12-24" Class 3: entire room saturated, ceiling involvement Class 4: specialty drying (hardwood, stone, plaster) requiring specialty equipment
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.
- Inspection + assessment
- Categorize (Cat 1, 2, 3)
- Identify class (1-4)
- Document everything (photo, video, moisture readings)
- Stop water source (or coordinate with plumber)
- Initial assessment to customer + insurance
Step 2: Extract standing water
- Truck-mounted extractor (carpet cleaning extractor adequate for clean water)
- Pump down to surface level
- Extract from walls, baseboards, hard surfaces
- 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
Cost: + 16-40 hour training. Annual continuing ed.
For business: at least one tech IICRC-certified per restoration job.
Equipment investment
Restoration equipment:
- Air movers: each, need 6-15 typical residential
- Dehumidifiers: each, need 2-5 typical
- Moisture meters:
- Thermal cameras:
- Pad drying equipment:
Investment.
Lease + rental available for one-off needs.
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:
- "Water category , extent class [Y]"
- "Drying time [Z days]; we monitor daily"
- "Likely scope: [estimate]"
- "Insurance: we work with [their carrier]; assign benefits to us"
- "Once dry, hand off to [reconstruction] OR we coordinate"
For day-2 monitoring:
- "Moisture readings today: [readings]"
- "Progress: [report]"
- "Adjustments: [equipment changes]"
