Sewage Cleanup in Seattle, WA
Seattle's Sewage Cleanup Experts
24/7 Sewage Backup Cleanup & Restoration
A sewage backup needs a different response than a clean water leak. Adriatic Water Restoration provides 24/7 sewage cleanup in Seattle, WA and Greater Seattle for sewer backups, sewage backups, sewage spills, overflowing toilets, toilet overflows, septic tank backups, and black water. Raw sewage and sewage water can carry harmful bacteria, viruses, pathogens, and other contaminants.
Our sewage cleanup services include sewage removal, contaminated water extraction, sanitization, drying, documentation, and build-back. We also provide water damage restoration when the loss causes structural damage or affects other materials.
24/7 emergency response: call (425) 894-8843 for a 60-90 minute response in Seattle and nearby Greater Seattle communities.

Seattle Sewage Cleanup Services
Sewage can affect flooring, walls, insulation, cabinetry, and other materials affected by the loss. We inspect the affected area, assess contamination, and determine what can be cleaned, disinfected, sanitized, or removed.
Black water from sewer backups, sewage backups, toilet overflows, or sewage spills can contain waste, bacteria, and biohazards. We use professional equipment and controlled air flow to protect clean areas and help prevent mold growth and further damage.
Sewer & Septic Backup Response
A blocked sewer system, failed toilet trap, drain problem, or septic tank backup may require a plumber or septic contractor. Adriatic handles cleanup and restoration, not sewer system or septic tank repair. If a septic tank sends raw sewage or sewage water into a flooded area, avoid the area until the source is corrected.
Our Sewage Cleanup Process
1. Emergency Response & Damage Assessment
We inspect the property, determine where sewage traveled, identify materials affected, take photos, and assess safety hazards.
2. Containment & Sewage Removal
We contain the affected area and remove sewage, sewage water, contaminated water, black water, and hazardous debris to protect clean areas and reduce further damage.
3. Removal of Contaminated Materials
Porous materials exposed to raw sewage may need removal if they cannot be safely cleaned and disinfected, including drywall, insulation, flooring, or trim.
4. Cleaning, Sanitization & Odor Control
We clean, disinfect, sanitize, and perform sanitization as needed to address contamination, harmful bacteria, viruses, pathogens, odors, and biohazards.
5. Structural Drying & Moisture Monitoring
Professional drying equipment and moisture inspections help dry walls, flooring, subfloors, and framing and reduce mold growth.
6. Documentation & Insurance Support
We document photos, cleanup, moisture conditions, and repairs for the insurance process and insurance claims. Your insurance company determines coverage, and we can provide information for your insurance agent.
7. Reconstruction / Build-Back
Adriatic can complete repairs and reconstruction/build-back after cleanup to restore damaged areas.

Common Sewage Problems
Sewage and black water losses can happen for several reasons. Our sewage cleanup services address:
- Sewer backups and sewage backups caused by a blocked sewer system or drain blockage.
- Toilet overflows and overflowing toilets involving waste, a clogged toilet, toilet trap, sink, or drain.
- Septic tank backups that send raw sewage or sewage water into a home or business. Septic tank or septic system repair belongs with the appropriate contractor.
- Sewage spills and sewage overflow involving hazardous waste or contaminants.
- Storm-related sewer backups or flooding that causes a flooded area or sewage overflow.
After a Sewage Backup
Keep people, children, and pets away from sewage and black water. Avoid electrical appliances and electrical hazards. Shut off power only from a safe, dry location. Rubber boots and protective equipment do not make raw sewage safe to handle.
If sewage is backing up, stop using the toilet or sink feeding the blockage. If safe, take photos and contact Adriatic. Fast sewage cleanup can help prevent contamination and lower health risks from bacteria, viruses, and illness. Recurring sewer backups, sewage backups, or toilet overflows need the source corrected before restoration continues.
