Certified for Contaminated Water
Some signals are obvious — a floor drain backing up with dark water. Others appear as slow drainage or strange odors that get worse over time.
If water or dark liquid rises out of your basement floor drain, shower drain, or toilet, you have an active sewage backup. Do not walk through it — the water is contaminated with harmful bacteria and pathogens.
A strong, persistent sewer odor in your basement or around any drain is a clear warning that sewage is either backing up or trapped in the line. The smell is caused by gases from decomposing waste — and it should never be ignored.
Sewage backup water is usually dark, murky, or greenish-black — a distinct appearance from clean water leaks. If the water has a cloudy look and you cannot tell where it came from, assume it is contaminated and stay out. Professional black water cleanup is required in these situations.
If your sinks, showers, or toilets are all draining slowly or backing up at the same time, the problem is likely in the main sewer line. This is not a clog you can plunge away — a professional sewage cleanup crew needs to assess the situation.
A toilet that gurgles when you flush, or a sink that makes a bubbling sound when water runs, often means air is trapped in the line due to a blockage. This is a strong indicator of an impending sewage backup that needs immediate attention.
Sewage leaves behind bacteria and moisture that promotes rapid mold growth. If you had a backup and now see mold, the cleanup was incomplete. Mold remediation is often required after sewage events to fully restore the space.
We offer a free inspection — a technician comes out, identifies the source, and tells you what you are dealing with. No charge, no pressure. Call (888) 336-2451 or schedule online here.
Sewage is a health risk. Your first priority is protecting yourself and your family while we get a crew to your home.
Do not walk through sewage water or let children or pets near it. Contaminated water contains harmful bacteria that can cause serious illness with any skin contact. Block off the area and stay out until the crew arrives.
Water and electricity are a dangerous combination. Go to your breaker panel and turn off the circuit for the area with sewage before anyone enters it. Do not attempt to wade in to reach outlets.
Do not flush toilets, take showers, or run sinks until the issue is resolved. Every bit of water you send down the drain can make the backup worse and push more contaminated water into your home.
Take photos and video of the sewage backup before anything is cleaned up. Include the affected areas, the water level, and any ruined items. This documentation is crucial for your inspection and insurance claim.
Do not try to clean sewage with household cleaners, bleach, or a shop vac. Contaminated water requires professional sanitization and removal. Do not touch anything in the affected area without protective gear.
The longer sewage sits, the more it soaks into porous materials and spreads contamination. Call (888) 336-2451 and we will have a certified crew en route while you secure the area and stay safe.

Sewage backups happen for several reasons. Understanding the cause helps our team address not just the cleanup but also the root issue.
Cause 01
Tree roots, grease buildup, or foreign objects can block the main sewer line between your home and the municipal system. When the line is blocked, sewage has nowhere to go but back up through your drains. This is the most common cause of sewage backups on Long Island.
Year-roundCause 02
During heavy rain, municipal sewer systems can become overwhelmed and push water back through home sewer lines. Homes in low-lying areas of Nassau and Suffolk are particularly vulnerable during nor'easters and coastal storms.
Seasonal — Jul to OctCause 03
Older Long Island homes often have cast iron or clay sewer pipes that can collapse, crack, or shift over time — especially in areas with older infrastructure. A broken pipe allows soil and debris to enter, creating a blockage that can be total.
Year-roundCause 04
Cooking grease, oil, food waste, and personal care products that get washed down drains build up inside pipes over time. This buildup narrows the pipe until it eventually causes a complete blockage and sewage backup.
Year-roundCause 05
Some Long Island communities have combined sewer systems that carry both stormwater and sewage. During heavy rain, these systems can overflow, sending a mix of stormwater and untreated sewage back into basements.
Seasonal — Mar to OctCause 06
Coastal storms and hurricanes can push seawater into sewer systems, causing backups in homes near the shore. This type of backup often requires storm and flood damage cleanup alongside sewage sanitization.

These are typical ranges — not a quote. Your free inspection provides the exact scope and cost.
Costs vary based on the amount of contaminated water, the affected area size, and whether porous materials need to be removed. The inspection and estimate are always free.
🛡️ Does Insurance Cover Sewage Cleanup?
Coverage depends on the cause and your policy. Here is the honest breakdown.
If a sudden blockage or municipal backup causes sewage to enter your home, many standard homeowners policies include coverage for the cleanup and sanitization.
In most cases, we send the invoice to your insurance company so you do not pay the full cost upfront — you typically just cover your deductible and we handle the rest.
Sewage backups caused by external flood events or storm surge often require separate flood coverage. Maintenance-related backups from tree roots may also be denied. We tell you honestly where your case falls.
