Sewage Cleanup & Category 3 Water Remediation
IICRC‑Certified | 24/7 Emergency Response | Safe, Compliant, Thorough
When your property is affected by sewage backup, toilet overflow, or Category 3 (Black Water) flooding, immediate professional action is critical. This type of contamination is not just messy — it’s toxic, hazardous, and destructive if not handled properly.
At Flat‑Out Plumbing, HVAC & Restoration, we are IICRC‑certified and trained to safely extract, disinfect, and remediate environments affected by Category 3 water, following strict industry protocols to protect your health, home, and insurance claim.
💀 What Is Category 3 Water?
- Raw sewage
- Human waste
- Floodwater from rivers, creeks, or storm drains
- Toilet backflows with feces
- Water that has sat stagnant for extended periods
These contaminants contain bacteria, viruses, parasites, and harmful microorganisms that can lead to serious health problems if not professionally remediated.
⚠️ Health Risks of Exposure to Category 3 Water
- Gastrointestinal infections
- Hepatitis A
- E. coli and Salmonella exposure
- Skin rashes and respiratory infections
- Mold growth within 24 – 48 hours
- Long‑term damage to drywall, flooring, insulation, and personal belongings
For your safety and the safety of your family or staff, do not attempt to clean it yourself. This is a job for licensed, trained professionals with the right safety protocols.

HoustonCalled these guys for a burst pipe emergency at 2 AM and they were at my house within an hour! The technician was professional, explained everything clearly, and had the problem fixed quickly. Fair pricing too. Will definitely use them again.

KatyOutstanding service from start to finish. They replaced my old water heater and updated some outdated fixtures. The team was punctual, clean, and respectful of my home. The quote was competitive and there were no surprise charges. Highly recommend!

James Greene
Sugar LandSolid work on fixing our kitchen sink leak and installing a new garbage disposal. The plumber arrived on time and completed the job efficiently. Only downside was the initial phone response was a bit slow, but the actual service made up for it.
