Not all water is equal. Water from a washing machine, dishwasher or toilet overflow (grey water) and water from sewage or outside flooding (black water) can carry contaminants that need a different approach than a clean supply-line leak.
Clean water can also become contaminated as it sits and contacts building materials, which is another reason quick response matters.
Common causes
- Washing machine and dishwasher discharge
- Toilet overflows
- Sewer backups
- Outside flood water

Contaminated Water Cleanup FAQs
Is grey water dangerous?
Grey water may contain contaminants that can cause discomfort or illness, and it can worsen into black water if left standing. Avoid contact.
Can you guarantee everything is safe afterwards?
We follow careful cleaning and drying practices, but we do not make health guarantees. If you have health concerns, consult a medical professional.
Why must carpets be removed?
Porous materials soaked with contaminated water are very difficult to clean reliably, so removal is usually the safer option.
