Sewage Cleanup

Sewage Backup Doesn't Wait. Neither Do We.

Category 3 black water demands immediate containment, extraction, and sanitation — not a mop and bucket. Grady responds across Cumming and North Georgia with biohazard protocols, HEPA containment, and insurance-ready documentation from first arrival through clearance.

Why Homeowners Call Grady First

Sewage backup is not a standard water loss. You need a team trained in Category 3 protocols — containment first, removal where required, and sanitation verified before anyone re-occupies the space.

Category 3 Trained Crews

Technicians arrive with Cat3 PPE, HEPA containment supplies, and biohazard disposal protocols — not residential drying equipment alone.

Immediate Containment

Affected zones are isolated on arrival to stop pathogen migration into clean areas, HVAC systems, and adjacent rooms.

Porous Material Protocols

Carpet, pad, drywall, and insulation exposed to black water are assessed for removal — not masked with surface cleaning.

Antimicrobial & Clearance Testing

Hospital-grade antimicrobials are applied per label and scope. ATP clearance testing verifies sanitation before rebuild begins.

Biohazard Documentation

Containment logs, removal records, treatment applications, and disposal manifests are captured for carrier review.

Licensed Category 3 Response

IICRC S500 Category 3 standards and Georgia trauma licensing — with containment, treatment, and documentation adjusters expect on regulated sewage claims.

Sewage Losses We Handle

From a single toilet backup to a main line failure affecting multiple units, Grady contains the contamination, removes unsalvageable materials, and restores the structure to a documented sanitary condition.

Main Line Backups

A blocked or collapsed sewer main forces raw sewage back through floor drains, tubs, and lowest fixtures in the home.

Toilet Overflows

A clogged drain or failed wax ring releases Category 3 water across bathroom floors and into subfloor assemblies below.

Floor Drain Backups

Basement and garage floor drains can reverse flow during municipal line surcharges or heavy rain events.

Septic System Failures

Overflowing tanks, saturated drain fields, or line breaks introduce untreated waste into living spaces and crawlspaces.

Commercial Sewage Events

Restaurants, offices, and retail spaces require rapid containment to limit business interruption and regulatory exposure.

Basement Sewage Flooding

Lower-level finished spaces absorb black water into carpet, drywall, and stored contents requiring controlled demolition.

Multi-Unit Sewage Losses

Stack backups in condos and apartments can affect multiple floors — each unit requires isolated containment and scope.

Storm-Sanitary Cross-Connections

Combined sewer overflow or storm drain intrusion introduces contaminated water through foundation and utility penetrations.

Founder's Perspective

Sewage is not ordinary water damage. Category 3 conditions require health controls, material decisions, disciplined cleaning, and documentation from first assessment through final clearance.

Documented Process

From Emergency Call to Sanitary Clearance

Every Category 3 loss follows a controlled sequence — containment before extraction, removal before drying, clearance before rebuild. This is the protocol Grady executes on sewage cleanup projects.

  1. Emergency Call

    Loss source, contamination extent, and occupant safety assessed. Cat3 dispatch initiated with containment supplies on board.

  2. Dispatch

    Biohazard crew mobilized with HEPA containment, Cat3 extraction equipment, and documentation tools ready to deploy.

  3. Containment Setup

    HEPA-filtered barriers, negative air, and clean-to-dirty zones established before any extraction begins.

  4. Black Water Extraction

    Category 3 water is extracted using dedicated equipment. Contaminated waste is contained and prepared for proper disposal.

  5. Porous Material Removal

    Unsalvageable carpet, pad, drywall, and insulation are removed, bagged, and documented for disposal and insurance scope.

  6. Antimicrobial Treatment

    Hospital-grade antimicrobials applied to structural surfaces per label, scope, and IICRC sanitation requirements.

  7. Structural Drying

    After sanitation, remaining structural assemblies are dried to verified moisture standards before clearance and rebuild.

  8. Clearance Documentation

    ATP results, moisture logs, Matterport capture, and disposal records compiled into a clearance file for insurance and rebuild planning.

Pathogen Control

Cross-Contamination Is the Hidden Risk

Sewage is visible on the floor. Pathogen migration is not. Black water wicks into porous materials, travels through wall cavities, and contaminates HVAC pathways long after the surface looks wiped clean.

Foot traffic, improper cleanup, and delayed containment spread bacteria and organic waste into previously unaffected rooms. Without HEPA barriers, absorption mapping, and verified clearance, contamination persists in materials you cannot see.

Grady isolates the loss zone on arrival, controls equipment and waste flow, and documents sanitation through ATP clearance — protecting both occupant health and your insurance claim.

Pathogen Containment Zones

HEPA-filtered barriers and negative air isolate Cat3 areas from clean living spaces.

Absorption Mapping

Thermal and moisture tools identify where black water has wicked beyond visible staining.

Cross-Contact Prevention

Clean-to-dirty workflow, dedicated PPE, and controlled equipment staging limit spread.

Post-Sanitation Verification

ATP testing and moisture logs confirm the structure meets clearance before re-occupancy.

Claims Education

Why We Document Everything

Sewage claims face higher scrutiny than clean water losses. Carriers need proof of contamination extent, proper Cat3 protocols, material removal necessity, and verified clearance — not assumptions that the area was sanitized.

Grady builds that record throughout the project. Adjusters can follow the biohazard story from containment setup through ATP clearance without gaps in scope or protocol documentation.

  • Containment & PPE logs
  • Material removal records
  • Antimicrobial applications
  • Moisture & drying logs
  • ATP clearance results
  • Biohazard disposal manifests

Sewage Cleanup FAQ

Is sewage backup a biohazard emergency?

Sewage is Category 3 water — grossly contaminated black water containing pathogens, bacteria, and organic waste. It requires immediate containment, proper PPE, removal of affected porous materials, and professional antimicrobial treatment. Grady responds 24/7 to stabilize the loss and prevent cross-contamination.

What should I do before the crew arrives?

Avoid contact with contaminated areas. Do not walk through sewage, track it to clean rooms, or attempt DIY cleanup. Shut off HVAC if safe to do so, keep children and pets away, and call Grady immediately. Our team will guide you on isolation steps until we arrive.

Do porous materials need to be removed after sewage exposure?

In most Category 3 losses, porous materials such as carpet pad, drywall at the flood line, insulation, and soft furnishings cannot be effectively sanitized and must be removed. Grady documents all demolition and disposal for insurance review.

How do you prevent cross-contamination?

We establish HEPA-filtered containment barriers, use dedicated Cat3 PPE and equipment, apply negative air pressure where appropriate, and maintain clean-to-dirty workflow zones. Foot traffic, tools, and waste are controlled to keep unaffected areas isolated.

Will insurance cover sewage cleanup?

Coverage depends on your policy and the cause of loss. Grady documents contamination zones, removal scope, antimicrobial treatment, drying logs, and clearance testing to support your claim. We provide Xactimate estimates and coordinate with adjusters when needed.

How do you verify the area is safe after cleanup?

After extraction, removal, antimicrobial application, and structural drying, we verify clearance using ATP testing, moisture readings, and documented sanitation protocols. Clearance records are included in the project file for insurance and peace of mind.

Do you serve Cumming and surrounding areas for sewage emergencies?

Yes. Grady provides 24/7 sewage and Category 3 water response across Cumming, Forsyth County, and North Georgia including Alpharetta, Johns Creek, Roswell, Dawsonville, Canton, and Suwanee.
