A sewage backup is the most hazardous water loss a North Hollywood home can take. Older homes off Lankershim and Magnolia still run clay lateral lines to the city main, and root intrusion or a grease-choked pipe pushes raw waste back up through the lowest drain. That water is Category 3 black water, so crews treat it as a health hazard from the first minute, not a mopping job.
Why a sewage backup is a health hazard
Black water carries bacteria, viruses, and parasites, and it soaks fast into flooring, drywall, and framing. Anything porous it touches has to be assessed for removal, not just wiped down.
- Raw sewage is Category 3 per the IICRC water-damage standard
- Contaminants wick into drywall, carpet pad, and subfloor within hours
- Standing waste off-gasses and spreads through HVAC returns
- The CDC warns direct contact with flood and sewage water risks illness, see CDC guidance on standing water
Raw sewage on your floor is a health emergency. Do not walk through it, call now and crews contain and decontaminate fast.
☎ Call (747) 850-6138How crews contain, extract, and disinfect
Crews arrive in full PPE, isolate the affected zone, and pull the waste before it spreads further. Extraction comes first, then removal of unsalvageable porous material, then hospital-grade disinfection of every surface that stays.
- Containment barriers and negative air to stop cross-contamination
- Truck-mounted water extraction of all standing black water
- Controlled demolition of saturated drywall, pad, and subfloor
- Antimicrobial and disinfectant applied to framing and hard surfaces
- Air scrubbing and deodorizing to clear the smell at the source
Safe disposal and drying it back to normal
Contaminated debris cannot go in a regular bin, and the structure has to be dried and verified before anyone reoccupies. Crews haul waste to an approved disposal facility and follow with structural drying and dehumidification until readings confirm the space is dry. Not sure what a job like this runs? The cost calculator gives a fast estimate.
- Bagged, sealed, and hauled to an approved disposal site
- Low-grain dehumidifiers and air movers sized to the space
- Daily moisture logs until framing and subfloor read dry
- Full documentation and direct billing to your carrier
Why older NoHo homes back up
The cause is almost always in the lateral line running out to the city main. Decades-old clay pipe is brittle and root-friendly, and a single blockage sends everything back through the house.
- Tree roots invading joints in old clay laterals
- Grease and wipes building a plug over the years
- Bellied or cracked pipe that traps solids
- Heavy rain overloading the shared municipal system
- A single ground-floor toilet or shower as the first backup point
