Why sewage backups need professional cleanup
Sewage is Category 3 water. It carries bacteria, viruses, and parasites that can make people sick. Porous materials it touches must be removed, and every surface must be cleaned and disinfected. That takes protective gear and equipment most homeowners do not have.
A sewage backup is not a job for a mop and bleach. Bleach does not reach into drywall, carpet, or wood, and stirring up sewage spreads contamination through the house.
Common causes of sewer backups in Garland
In Garland, most sewer backups come from tree roots in the main line, old cast iron or clay pipes that crack or sag, grease and wipes that clog the line, and city main backups during heavy rain.
- Tree roots. Mature trees in older neighborhoods send roots into joints in the sewer line.
- Old pipe. Cast iron drains in 1950s to 1970s homes rust and scale inside. Clay pipe joints shift with the clay soil.
- Clogs. Grease, wipes, and paper towels block the main.
- Heavy rain. Storm water entering the sanitary system can back up into the lowest drains.
- Slab movement. Expansive clay can belly or break drain lines under the slab.
Signs of a sewer backup
- Water comes up in the tub or shower when you flush
- Several drains are slow or gurgle at once
- Sewage smell from floor drains or the yard cleanout
- Toilets overflow without being clogged
- Wet spots or odor near the yard cleanout
Our sewage cleanup process
Sewage cleanup in Garland follows a strict order: keep people away, stop drain use, extract the waste, remove contaminated porous materials, clean and disinfect, dry the area, and verify it is safe before rebuild.
- Protect people. The crew wears protective suits, gloves, boots, and respirators. Kids and pets stay away.
- Stop the flow. A plumber clears the line. Nobody uses drains until it is fixed.
- Extract waste. Sewage water and solids are pumped out and disposed of properly.
- Remove porous materials. Carpet, pad, drywall to above the wet line, insulation, and particleboard that touched sewage are bagged and removed.
- Clean and disinfect. Hard surfaces and framing are scrubbed and treated with EPA-registered disinfectant.
- Dry and verify. Air movers and dehumidifiers dry the area, and readings confirm it is ready for repair.

Is sewage backup covered by insurance?
Most Texas homeowners policies exclude sewer and drain backup unless you added a water backup endorsement. If your policy has it, the cleanup is usually covered up to the endorsement limit. A toilet overflow from a supply line is treated differently from a main line backup.
Check your declarations page for "water backup" or "sewer backup" coverage. Take photos before cleanup begins and keep the plumber's invoice showing the cause.
Sewage backups in Garland homes: what crews see
Most Garland sewage calls come from homes built before 1980 with cast iron drains, from big trees near the main line, and from heavy rain that overloads the sanitary sewer. The lowest drain in the house, usually a first-floor shower or tub, is where the backup shows up first.
In slab-on-grade homes, the main drain runs under the foundation. When expansive clay shifts, a section of pipe can sag, called a belly, and collect waste until it backs up. A camera inspection by a plumber shows the cause so it can be fixed for good.
The City of Garland maintains the public sewer mains, and homeowners are generally responsible for the private service line from the house to the city connection. If you suspect a city main problem, report it to the city right away and keep the plumber's findings.
After cleanup, ask the provider for the disinfection record and photos of what was removed. Those documents matter for your claim and if you sell the home later.
