Sewage Backup Cleanup
IICRC Cat 3 Black Water Restoration
Sewage backup is Category 3 black water per IICRC S500. Different scope, different protective equipment, different rules. Anything porous it touched comes out. Anything semi-porous gets antimicrobial pretreatment and verification. Flood Titan Restoration is IICRC Certified Firm #70249559. Full Tyvek PPE, HEPA air filtration, negative-air containment, and S500 Category 3 protocol from the moment we step on site. Owner-operated, locally based in Southlake.
Sewage Backup Is Not Just Water
Sewage backup water carries pathogens including E. coli, hepatitis, and giardia. The IICRC S500 standard classifies it as Category 3 (the highest contamination level) and the cleanup is fundamentally different from a clean-water loss. Porous materials are removed, not dried. Workers wear full PPE. The space is contained under negative air pressure with HEPA-filtered exhaust to outside.
Do Not Try To Clean This Yourself
Standard household cleaners do not address the biohazard load. A wet-vac does not filter pathogens. Even brief skin contact with sewage carries real infection risk. Keep family and pets out of the affected area. Call 817-95-FLOOD and let us bring the right PPE and the right scope.
Why DFW Sewage Backups Happen
Main Line Blockage
Tree roots intruding the lateral sewer line between the house and the city main is the most common cause we see in older DFW neighborhoods (Southlake older sections, Colleyville, Keller historic district). Backs up through the lowest fixture, usually a tub drain, shower drain, or floor drain in the lower level.
City Main Backup
Storm event overloads the municipal sanitary line. Backflow into the house through any fixture lower than the street main. This is the worst-case scenario because the volume is unpredictable and the contamination load is at maximum.
Toilet Overflow With Contamination
A clogged toilet that overflowed clean water from the supply tank is Cat 1. The same toilet overflowing waste from the bowl side is Cat 3 from the first inch. We treat the source, not the appearance.
Sump Pump Failure
Less common in DFW than the Midwest because most local homes do not have basements, but a failed sump in a homes with a below-grade utility room or storm cellar can flood with grey or black water from accumulated infiltration plus any drain tile connections.
What We Do When We Arrive
Step 1: PPE & Containment
Full Tyvek suits, P100 respirators, gloves, eye protection. Affected area sealed off with poly sheeting. Negative-air HEPA scrubber establishes pressure differential and exhausts to outside. This is the perimeter that protects the rest of your house.
Step 2: Bulk Waste Extraction
HEPA-filtered extractors pull standing waste water. Solids are scooped, bagged, and disposed of as biohazard. We do not pump waste through residential drains.
Step 3: Mandatory Porous Material Removal
Per IICRC S500 Category 3 protocol (§12.1), porous materials that contacted Cat 3 water are non-restorable: carpet, carpet pad, drywall (typically the bottom 24 inches), saturated insulation, and absorbent finishes. They are bagged, photographed, and disposed of properly.
Step 4: Antimicrobial Pretreatment
EPA-registered antimicrobial agent applied to all semi-porous surfaces that came in contact with Cat 3 water (concrete, framing, sub-floor wood). Verification swabs taken on critical areas. ATP testing available on request.
Step 5: Structural Drying
Once contamination is addressed, LGR dehumidifiers and air movers dry the remaining structure to IICRC S500 targets. HEPA scrubbers continue running. Equipment runs 24/7. Daily moisture readings logged.
Step 6: Verification & Rebuild
Final ATP swabs to confirm sanitization. Moisture readings confirm dry. Then replace removed materials: drywall, insulation, flooring, base trim, paint. Same crew, same project number. Final certificate of completion issued with photo and lab documentation.
Insurance & Sewage Backup
Sewage backup is the one water-damage category that often requires a specific insurance rider. Standard Texas homeowners policies typically exclude sewer backup unless you have purchased the Water Backup & Sump Overflow endorsement (sometimes called Sewage Backup Coverage). This rider is inexpensive (usually under $100/year) but the homeowner has to elect it.
What we do regardless of coverage: document the loss to IICRC S500 standards, photograph contamination, log each affected material, write an Xactimate-format scope, and provide it to your adjuster. If the rider exists, the carrier pays for the cleanup minus your deductible. If it does not, the cost is out of pocket and we work with you on scope priorities. Either way we tell you up front what your policy covers, not after the work is done.
