Sewage Backup Cleanup in Lewisville, TX: Health Hazards and the Professional Sanitization Process

A sewage backup is not the same as a clean-water leak, and treating it like one puts your family at real risk. What looks like dirty water on the floor is actually a biohazard carrying live bacteria, viruses, and parasites. In Lewisville, where many mid-century homes still run on original cast-iron and clay plumbing, these backups are more common than homeowners expect, and they demand a careful, professional response.

Why Sewage Is a Genuine Health Hazard

Restoration professionals classify sewage as "Category 3" or "black water," the most contaminated class of water intrusion. The reason is biological. Raw sewage is a living soup of pathogens, and direct contact, inhalation of aerosolized droplets, or touching contaminated surfaces can all make people sick.

The list of what hides in a backup is sobering:

• **Bacteria** such as E. coli, Salmonella, and Shigella, which cause severe gastrointestinal illness, plus organisms behind cholera-like infections and other diseases.
• **Viruses** including hepatitis A and rotavirus, which survive on surfaces and spread easily within a household.
• **Parasites** like Giardia and Cryptosporidium, whose hardy cysts resist ordinary cleaning and can trigger long-lasting intestinal infections.

Beyond the pathogens, sewage releases gases and feeds mold growth within 24 to 48 hours in our humid North Texas climate. Children, older adults, pregnant women, and anyone with a compromised immune system face the highest danger. This is why the safe move is to keep people and pets away from the affected area and call a professional rather than mopping it up yourself.

Why Porous Contaminated Materials Have to Go

One of the hardest things for homeowners to accept is that some materials simply cannot be saved after sewage contact. The issue is porosity. Hard, non-porous surfaces like sealed tile, glass, and metal can be cleaned and disinfected because contaminants stay on the surface. Porous and semi-porous materials absorb sewage deep into their structure, where pathogens settle into spaces no surface cleaner can reach.

That means carpet and padding, drywall that wicked up contaminated water, insulation, particleboard cabinetry, and upholstered furniture usually have to be removed and discarded. Trying to dry and reuse them traps bacteria and mold inside your home, creating a hidden source of illness and odor that resurfaces for months. In a flooded Lake Lewisville waterfront home, where standing water and high humidity already accelerate microbial growth, cutting corners here almost guarantees a recurring problem.

Professional crews follow IICRC standards to decide exactly what stays and what goes. The goal is to remove only what must be removed while documenting everything thoroughly for your insurance claim, so you are not paying out of pocket for damage that should be covered.

The Professional Sanitization Process

Proper sewage cleanup follows a disciplined sequence rather than a quick spray-and-wipe. After the source of the backup is stopped, technicians arrive in personal protective equipment and contain the work area to prevent cross-contamination into clean parts of the house.

From there, the process moves through clear stages. First comes extraction of standing sewage and the controlled removal and bagging of contaminated porous materials for proper biohazard disposal. Next, every salvageable hard surface is cleaned to lift away organic residue, because disinfectants cannot work properly on top of soil and grime. Then technicians apply EPA-registered antimicrobial and disinfectant products, the same class of products regulated specifically to kill the bacteria, viruses, and parasites found in sewage, allowing the required dwell time for them to actually do their job.

Finally, the structure is dried with commercial air movers and dehumidifiers, and moisture levels are monitored with meters to confirm the area is genuinely dry, not just dry to the touch. This step matters everywhere in Denton County but especially in older Old Town Lewisville homes, where moisture loves to linger inside wall cavities and original subflooring. Many crews finish with confirmation that surfaces are sanitized and odor-free before any reconstruction begins.

Go Green Restoration is bonded, insured, and IICRC- and EPA Lead-Safe certified, which matters because sewage work intersects with both biohazard handling and the renovation of older homes that may contain lead-based materials. That certification means the work is done to recognized industry standards from cleanup through rebuild.
