What Is Decontamination After Gray/Black Water Events?
A disciplined, documented process to remove contaminated materials, disinfect exposed surfaces, and dry the structure back to target—while preventing spread to clean areas.
For Category 2 (significant contamination) and Category 3 (sewage/floodwater), porous materials in contact are typically removed; remaining surfaces are cleaned and disinfected with products appropriate to the water category and material type, then dried and verified.
Why Choose White Glove Plumbing
Plumbing + restoration = faster recovery: We fix the cause (sewer line, toilet, pump, slab leak) and perform decontamination + dry-down + rebuild—no hand-offs.
Standards-aligned methods: Hard containment, negative air (as indicated), source removal, detergent clean, EPA-registered disinfection, chambered drying, and verification.
Occupant-safety mindset: Clear egress, sealed work zones, and documented re-entry guidance.
Insurance-ready documentation: Photos, moisture/psychrometric logs, chemical labels + dwell times, and a clean scope narrative your adjuster understands.
Immediate Actions (What to Do Now)
Avoid contact with affected areas; keep kids and pets away.
Shut water at the fixture or main if an active leak exists.
Do not run HVAC across contaminated zones—it can spread aerosols.
Do not discard materials yet; we’ll document for insurance.
Call our 24/7 dispatcher—we’ll secure the scene and start a safe plan.
Common Projects We Manage
Toilet overflows with solid waste onto flooring/walls
Sewer line backups into tubs, showers, or floor drains
Washing machine drain failures saturating floors and walls
Storm/floodwater intrusion carrying soil and organic load
Commercial restrooms/kitchens with sanitary sewer overflows
Crawlspace/utility room black-water contamination
Assessment, Category & Safety Plan
Identify water category/class, affected assemblies, and migration paths. Establish PPE requirements and a plan for containment, egress, and waste handling.
Source Control & Containment
Repair the cause (plumbing or pump). Install hard containment with negative air/HEPA when indicated; protect/cover registers; create clean load-out routes.
Controlled Removal (Source Removal)
Extract standing water; remove porous materials that contacted gray/black water (e.g., carpet/pad, affected drywall/insulation, MDF toe-kicks). Bag and dispose per local rules.
Detergent Cleaning & EPA-Registered Disinfection
Detergent pre-clean to reduce soil load; apply EPA-registered disinfectants with documented dwell times; detail clean non-porous and semi-porous surfaces.
Chambered Drying & Verification
Deploy LGR dehumidifiers and directed airflow; log RH/GPP and material moisture until targets are met. Perform final wipe-down and odor/visual checks.
Rebuild & Close-Out Packet
Present line-item rebuild scope (drywall, trim, cabinets, flooring). Deliver photos, moisture logs, chemical labels/SDS, dwell-time notes, and re-entry guidance.
What’s Included
Containment & site protection (negative air/HEPA as indicated)
Water extraction & controlled demolition of impacted porous materials
Detergent pre-clean and EPA-registered disinfection with dwell-time logs
Chambered structural drying with daily psychrometric and moisture readings
Odor control & final detailing of non-porous surfaces
Documentation packet (photos, logs, product labels/SDS, close-out notes)
Costs & Timelines (What to Expect)
Typical duration:
Stabilize + demo + disinfection: ½–1 day for smaller scopes.
Dry-down: 2–4 days depending on materials and extent.
Rebuild: 1–3+ days based on finishes (drywall/trim/floors).Cost drivers: Category (2 vs. 3), square footage, demo volume, equipment days, after-hours scheduling, and access constraints (bathrooms/crawlspaces).
Upfront clarity: We provide a line-item estimate and daily progress updates; the same file is shared with your adjuster.
Insurance & Claims Help
Carrier-friendly evidence: Before/during/after photos, scope sketches, moisture/psychrometric logs, and disinfectant labels with dwell times.
Cause vs. resulting damage: We document source repair separately from mitigation and rebuild (coverage varies).
Supplements: Hidden contamination found after opening assemblies is documented and submitted promptly.
Risks of Waiting (Why Act Now)
Pathogen exposure and odor set-in as contamination dries on surfaces.
Cross-contamination into clean rooms and HVAC systems.
Material failure (swollen MDF, delaminated laminates) and mold growth.
Higher scope & cost from expanded demo and longer dry-down.
Methods, Materials & Quality Standards
Controls: Hard containment, negative air, sealed load-out, register protection.
Chemistry: Detergent pre-clean followed by EPA-registered disinfectants matched to material/surface and category; documented dwell times.
Removal rules of thumb: Porous materials contacting Category 3 are typically removed; semi-porous/non-porous are cleaned & disinfected if structurally sound.
Drying science: LGR dehumidifiers and directed airflow; monitor RH/GPP and material moisture until targets achieved.
Safety & compliance: PPE, compliant waste handling, optional third-party oversight when required; coordinate pre-disturbance testing (asbestos/lead) if building age/scope indicates.
Verification: Visual/odor check and documented readings; optional third-party clearance available upon request.
Frequently Asked Questions
Can we just mop with bleach and keep the carpet?
No. Porous materials in contact with Category 3 water are typically removed per industry practice. We’ll explain what can be cleaned vs. what must go.
Is the area safe for kids and pets after cleaning?
We provide re-entry guidance once cleaning/disinfection and dry-down are complete. Until then, keep the area closed.
Will you clean or replace cabinets and baseboards?
We salvage when safe (solid wood/plywood) and replace swollen/delaminated MDF or visibly contaminated components.
Do you always use negative air?
When aerosol or odor control is needed or when working in occupied spaces, yes—it helps prevent spread.
How long until we can use the bathroom again?
Often after decontamination day for unaffected fixtures/adjacent rooms; affected rooms reopen post-dry-down and verification. We’ll outline the plan onsite.
Do you handle the rebuild too?
Yes—drywall, trim, cabinets, flooring, and paint with clean documentation for your carrier.
