Contact 911 Flood of Long Island immediately if you experience a sewage backup event, we will dispatch someone to assess and quote the repair.


The Sewage Removal Process

First we perform a sewage damage assessment by walking through the property with you and create a scope of work for approval.

Next we will create a detailed sewage damage estimate for cleanup and property reconstruction.

Water Extraction
Once the estimate is approved, we will begin our sewage water extraction and remove any wet contents like the carpet, padding, and drywall for salvage or disposal. We will also put the property’s contents on blocks.

Sanitization is next, we will use an antimicrobial substance to protect against any bacterial growth that could lead to dangerous illness.

We will then begin drying and dehumidifying the flooded space using air movers, dehumidifiers, and air scrubbers. These machines will run for at least 72 hours straight in order to ensure your area is as dry as possible.

Finally, we will perform a complete property reconstruction, where we will return your property to its pristine, pre-flooded state.

What People Are Saying About Us

Real Customer Reviews about Our Sewage Cleanup Service

Jennifer W. On 1/11/16

My sewer backed up into my basement on 1-5-2016. When the city cleared the blockage the water drained and left raw sewage on the floors and walls. My insurance agent recommended FLAG ENTERPRISES and a couple of other companies. I chose FLAG. I hired them on 1-7-2016 and they did the job that same day. They cleaned what could be saved and bagged and disposed of all that was ruined, (which was almost everything). They deodorized and sanitized everything as well as dried everything out. 3 days to dry out with their high powered equipment. Upon FLAG retrieving their dehumidifiers I requested that they deodorize again as there was still a slight odor and they did. I would highly recommend FLAG because they were fastest to respond for free estimate and job when hired, because of their knowledge regarding sewer clean-up. Careful not to track raw sewage through the rest of my house. Hauled away all of the garbage. Most importantly they documented everything perfectly in writing and with photos, (before and after). Which is needed for insurance, claims, lawsuits etc.

Dana B. on 3/26/2015

Had a sewer pipe burst & dump Nast stuff all over my basement. My insurance company contacted Flag Enterpriises & they were there right away. The guys were GREAT!! Worked hard to gut & clean my basement. They left the place as spotless as possible & were so professional. I would highly recommend them to anyone.

Colleen B. on 3/4/2015

I called at 1:30 am in a total panic with sewer water pouring into my house..and woke up Tom. He was so calming and reassuring even in the wee hours of the morning. They arrived the next day and Ed really put all my fears to rest that his company was going to get the clean up done! Indeed they did! Paul was a real down to earth nice guy who made sure everything was completed and not only was clean but smelled clean as well. I highly highly highly recommend anyone to call Flag for any job they need! While I certainly hope I don't get water in my basement again at least I know who I will call! Thank you all for being professional and patience with me!
