The Dangers of Sewage Exposure: Why You Need a Professional

Attempting to clean a sewage backup yourself is extremely dangerous. Exposure to black water can lead to serious health conditions. The water can contain:

  • Bacteria: E. coli, Salmonella, and other harmful pathogens.
  • Viruses: Hepatitis A, Rotavirus, and other infectious agents.
  • Parasites: Giardia, Cryptosporidium, and other intestinal parasites.
  • Toxins: Harmful chemicals and contaminants flushed into the sewer system.

Our team uses personal protective equipment (PPE) and specialized techniques to handle these biohazards safely, ensuring your property is returned to a sanitary condition without risking your health.

Our Certified Sewage Cleanup & Restoration Process

We follow a comprehensive, multi-step process to ensure your property is safe, clean, and fully restored.

Step 1: Emergency Assessment & Containment

Upon arrival, our first priority is to stop the source of the sewage backup if possible. We then assess the extent of the contamination and establish containment barriers to prevent the spread of biohazards to unaffected areas of your property.

Step 2: Sewage Extraction & Debris Removal

Using powerful, truck-mounted extraction equipment, we remove all standing sewage and contaminated water. All non-salvageable porous materials that have absorbed sewage—such as drywall, carpet, insulation, and upholstered furniture—are carefully removed and disposed of according to biohazard regulations.

Step 3: Cleaning & Hospital-Grade Disinfection

Once the bulk of the sewage is removed, we meticulously clean all remaining surfaces. We then apply EPA-approved, hospital-grade disinfectants to kill all bacteria, viruses, and fungi. This critical step ensures that all harmful pathogens are eliminated.

Step 4: Advanced Deodorization & Odor Removal

Lingering odors are a common problem after a sewage backup. We use advanced deodorization techniques, such as thermal fogging and hydroxyl generation, to attack and neutralize odor-causing molecules at their source, leaving your property smelling clean and fresh.

Step 5: Structural Drying & Dehumidification

With the area fully sanitized, we set up industrial-grade air movers and dehumidifiers to thoroughly dry all affected structures. This step is crucial for preventing secondary damage, such as mold growth, which can begin within 24-48 hours.

Step 6: Reconstruction & Restoration

After the property is certified clean, dry, and safe, our reconstruction team can begin the final repairs. We handle everything from replacing drywall and flooring to painting and finishing, restoring your property to its pre-loss condition.

Flood Tech arrived quick, got set up, and got right to work. Thier project manager really seems to care to ensure that things are done right and done completely. Very clean work.

Khashayar P.
We had a pipe burst in our Rockville home and couldn’t find a dependable water-damage crew until a friend recommended Flood Tech USA. They removed the wet drywall and damaged baseboards, and used vacuums and dehumidifiers to pull out every bit of moisture. For three days straight, they arrived each morning, fine-tuned their equipment, checked moisture readings, and made sure nothing stayed damp. We couldn’t possibly be happier with how they handled everything. They genuinely care about the quality of service. I highly recommend them.

We live in Old Lee Hills, Fairfax and an AC condensation leak soaked our upstairs closet and ceiling below. FloodTech USA responded quickly, contained the damage, and made sure everything was dry and mold free within a couple of days. Great water damage restoration company in Fairfax City!

As a local realtor in the DMV area, I’ve worked with several restoration companies, but FloodTech USA truly stands out. I recently needed urgent water damage mitigation for a listing in Vienna,VA with a leaking water heater in the basement. They responded immediately, quickly extracted the water, thoroughly dried the space, and helped prevent further damage. Thanks to their fast action and quality work, we avoided delays and kept the closing on schedule. I highly recommend FloodTech USA for water damage restoration in Fairfax County.

This isn’t the first time we’ve had to deal with water damage, and every time, Pasha from FloodTech USA has been our go-to. He is consistently professional, knowledgeable, and incredibly thorough. Pasha goes above and beyond to make sure everything is fully dried, treated, and safe, he explains the process clearly and never cuts corners. You can tell he truly cares about doing the job right.

It’s rare to find someone so dependable in this industry, but with Pasha, we always know we’re in good hands. We’ve recommended them before and will continue to do so without hesitation.
Kate B.
Flood Tech USA is fantastic. I've had to call them twice. Both times they were responsive and fast. They knew exactly what needed to be done to dry everything out and avoid the onset of mold and mildew. I highly recommend them and would definitely call again.

After last week's storms, we ended up with a flooded basement at our home near Tysons Corner. I called FloodTech USA based on a recommendation, and they were fantastic from start to finish. They responded quickly, assessed the water damage, and handled everything efficiently. Highly recommend FloodTech USA if you're dealing with any water damage or flooding issues.
Carlos C
We've been working with Flood Tech USA for several years now, and they continue to exceed our expectations. Our basement is prone to flooding, so finding a reliable water damage and mold remediation company in Herndon, VA was critical—especially because I have asthma and indoor air quality is a top priority.

Our first experience with Flood Tech was during a major flood where over half of our basement was affected. They arrived promptly and took immediate, professional action to contain and remediate the damage.

The second time was due to an AC leak that caused hidden mold growth. Again, they responded quickly and thoroughly addressed the issue. I also ordered an air quality test from another company for peace of mind, and the results came back clear—thanks to their meticulous work.

What really sets Flood Tech apart is the owner, Pasha. He personally oversaw both projects, kept us informed throughout, and never once tried to up-sell us on unnecessary services. He's responsive, respectful, and clearly committed to doing the job right.

If you need flood remediation or mold removal done professionally and with genuine care, don’t hesitate to call Flood Tech USA. We won’t use anyone else.

Frequently Asked Questions

What should I do if I have a sewage backup?

Your safety is the top priority. Evacuate the affected area immediately, especially children and pets. Turn off your main water supply if you can do so safely. Do not use any plumbing fixtures or appliances that use water. Call FloodTech USA at 703-995-9886 for 24/7 emergency service.

Is the smell from a sewage backup dangerous?

Yes. The foul odor is caused by sewer gases like hydrogen sulfide, methane, and ammonia, which can be harmful or even toxic in high concentrations. These gases can cause nausea, headaches, and respiratory issues. Our deodorization process eliminates these harmful gases.

How long does sewage cleanup take?

The timeline varies depending on the size of the affected area and the extent of contamination. A small backup might take 1-2 days for extraction and drying, while a larger event requiring significant material removal and reconstruction could take longer. We will provide a detailed timeline after our initial assessment.

Will my insurance policy cover sewage backup damage?

Standard insurance policies often have limited or no coverage for sewage backups unless you have a specific endorsement or rider. We recommend reviewing your policy. Regardless of coverage, we provide all necessary documentation to support your claim and can work directly with your insurance adjuster. For more information, visit our blog.

What is the difference between clean water, grey water, and black water?

Clean Water (Category 1): From a broken supply line. Not immediately harmful. Grey Water (Category 2): From appliance discharge (e.g., washing machine, dishwasher). May contain some contaminants. Black Water (Category 3): Raw sewage or floodwater from rivers. Highly contaminated and dangerous. Sewage backups are always considered black water and require professional biohazard remediation.
