A washer hose burst and soaked the laundry room and hallway. They were out the same day, extracted the water, and saved the hardwood by drying it fast. Fair and straight with me about the whole process.

What South Shore neighbors say
The bay came up during a nor'easter and our finished basement was under a foot of water by morning. A crew was pumping it out within the hour and dried the whole level to a reading they showed me. They handled the claim paperwork start to finish.
Colleen M.
A supply line let go in the upstairs bathroom while we were at the beach and it ran down into the kitchen. They shut the water, pulled the soaked ceiling, and dried inside the walls without gutting the room. Honest about what could be saved.

A sewage backup is the most hazardous water loss a home can have. It is Category 3 black water, carrying bacteria and pathogens, and it is not something to handle with a mop and a bucket. On the South Shore, heavy rain and a high water table can overwhelm lines and push waste back up through a floor drain or a downstairs toilet. Our protected restoration crews contain it, remove it, disinfect, and dry the space so it is safe again.
What causes sewage backups here
In Bay Shore and the surrounding Islip communities, the common causes are:
- Heavy rain and a high water table overwhelming sewer and septic systems
- Tree roots or grease blocking a main line
- A failed or overwhelmed septic system on properties that have one
- A municipal backup that pushes waste up through the lowest drain
How we clean up sewage safely
Safety drives every step, and our crews are trained and protected for it:
- Contain the area and set up protective procedures to stop the spread
- Extract the black water and remove contaminated porous materials
- Clean and disinfect every affected surface with professional antimicrobials
- Dry the structure to a verified reading and confirm it is safe
Because this is contaminated water, we remove more than we would on a clean water extraction or basement flood, for your family's safety.
Sewage backing up into your home? Keep everyone away and call. A protected Bay Shore crew is about 45 minutes out.
☎ Call (631) 239-3879Stay away until it is handled
The CDC and EPA both stress that sewage contact is a real health risk and that porous materials it touches should be removed and the area disinfected. Keep children and pets out, do not run water that drains to the backup, and let a trained crew handle it. Our work follows IICRC guidelines for Category 3 losses.
Do not run water during a backup
If sewage is coming up through a drain or toilet, stop using sinks, tubs, the washer, and toilets in the house. Every gallon that goes down adds to what is coming up until the line is cleared.
A main-line clog pushed sewage into the finished basement and I did not know what to do. They showed up in gear, contained it, hauled out the ruined material, and disinfected everything. The smell was gone.

Answers
Sewage & Black Water Cleanup questions, answered
Water in your home right now?
Do not wait for the FAQ. A local South Shore crew is standing by 24/7.
(631) 239-3879 Call nowWhy is sewage cleanup more serious than other water damage?
Sewage is Category 3 black water, meaning it carries bacteria, viruses, and other pathogens. Contact can make people sick, so it requires containment, protective gear, removal of contaminated materials, and thorough disinfection, not just extraction.
Can I clean up a small sewage backup myself?
It is not worth the health risk. Even a small backup contaminates everything it touches, and household cleaners do not disinfect to a safe standard. A trained, protected crew removes the hazard and verifies the area is safe.
What has to be thrown out after a sewage backup?
Porous materials that absorbed the black water, such as carpet, pad, drywall, and insulation, generally must be removed. Hard, non-porous surfaces can be cleaned and disinfected. We remove only what safety requires and save what we can.
Is sewage backup covered by insurance?
Many homeowners policies cover sewage and water backup only as an added endorsement rather than by default. We document the loss thoroughly, and if you carry that coverage it usually applies. We work directly with your carrier.
Will the smell go away?
Yes. The odor comes from contamination and moisture. Once we remove the contaminated materials, disinfect the surfaces, and dry the structure to a verified reading, the smell goes with it.
Why do backups happen more in heavy rain?
On the South Shore, heavy rain and a high water table can overwhelm sewer and septic systems, forcing waste back up through the lowest drains. That is why backups often happen during or right after a big storm.
