Sewage cleanup removes waste water from a backup, discards porous materials it touched, cleans and treats the surfaces and dries the structure. Sewage is Category 3 water and carries bacteria, so crews wear protective gear and work in controlled steps. A crew serving Celina and Collin County is dispatched as fast as one is available.
If a toilet, tub or floor drain is pushing waste water into the house, stop using every drain, leave the affected rooms and keep children, pets and anyone with a weak immune system away from them. Do not flush, run the washing machine or use the dishwasher, because each one adds water to a line that has nowhere to send it. Do not try to clean it up with a household vacuum or a mop and bucket.
A sewage backup is one of the few water losses where the water itself is the main hazard. A burst supply line floods a room with clean water. A backup floods it with waste, and the water can carry bacteria and viruses into carpet, drywall, cabinets and the slab. That is why the work looks different: more protective equipment, more removal, more cleaning and a slower, more careful sequence.
This page explains how a crew handles a sewage loss, how a backup differs from other leaks, what backups look like in newer slab homes and older districts around Celina, and why the cost and the insurance picture are different. Clearing the blocked line is a licensed plumber's job. Cleanup, drying and the repairs afterward are the restoration side.
Do not wade through sewage, touch it with bare hands or use a household vacuum on it. Wash hands thoroughly after any contact, keep children and pets out and call a licensed plumber for the blocked line.
The crew sets up protective gear, seals off the affected area with plastic sheeting where needed and keeps foot traffic from carrying contamination into clean rooms.
Pumps and wet vacuums remove standing water. Solids are bagged and disposed of properly, and the plumber's work on the blocked line happens in parallel or before the cleanup starts.
Carpet, pad, insulation and drywall that soaked up sewage cannot be reliably cleaned, so they are cut out and bagged. Wall cuts go well above the visible water line.
Slab, framing, baseboard and cabinet boxes are washed and treated with products suited to each surface. Contents are sorted into those that can be cleaned and those that should go.
Air movers and dehumidifiers dry what remains, and moisture meters and thermal tools confirm the readings, with photos and logs you can share with your insurer.
Replacement drywall, flooring and paint are priced separately once the structure tests dry, so you approve each stage before it starts.
Sewage jobs are priced higher per square foot than clean-water jobs because of protective gear, disposal, cleaning and the amount of material removed. The range depends on the size of the area and how far the backup spread.
| Job | Typical range | What it includes |
|---|---|---|
| Category 3 (black) water, per square foot | $7 and up | Some published ranges run to $10 or more |
| Contained residential sewage backup cleanup | $2,000–$10,000 | A national guide figure, not specific to north Texas |
| Finished multi-room sewage loss (a national guide figure) | $8,000–$20,000 or more | Includes more removal and repair |
| Drying and dehumidifying | $700–$2,000 | After cleaning, equipment and monitoring |
| Drywall replacement, finishing included (per sq ft) | $3–$8 | Repair work, quoted separately after drying |
These are typical ranges for Collin County in 2026, confirmed on site before any work starts. The plumber's charge to clear or repair the line is separate and is not included.
Sewage is Category 3 water, the most contaminated class in the IICRC S500 standard. It can carry bacteria and viruses, so crews wear protective gear and remove porous materials such as carpet and drywall instead of drying them. Surfaces are cleaned before drying starts, not afterward.
IICRC, the industry body that publishes S500, is not a regulator. Its categories are a working standard, not Texas law. A clean supply line gives Category 1 water, gray water such as a washer drain is Category 2, and anything from a toilet, sewer or flood is Category 3.
The reason porous materials go is practical. Carpet pad, insulation and drywall act like sponges, and washing the surface does not remove what has soaked in. Hard materials such as the concrete slab, framing and tile can be cleaned. Cabinets are judged case by case based on how far the water rose.
Backups come from blocked or damaged lines. In newer slab homes the cause can be a clog or a construction-era defect, and in older districts such as Downtown Celina or Historic Downtown McKinney it can be aging lines and tree roots. Heavy rain can also overload a sewer system.
Most of Celina's housing is new, so failed cast-iron pipe is not the typical call. A clog, a grease or wipes blockage, or a problem with how a line was installed is more likely. Whether a defect belongs to the builder is a question for a plumber and for your builder's written warranty.
In older parts of the area, the picture changes. Downtown Celina's Square and Historic Downtown McKinney have older buildings and aged lines, and restaurants there can produce grease-line backups. Allen's city council has approved work on water and sewer lines in several districts, which shows that parts of that network are aging.
A backup that happens during or just after heavy rain may involve stormwater getting into the sewer system. If rain water also entered the house from outside, the flood damage cleanup page covers that part.
A standard homeowners policy usually does not cover sewer and drain backup unless you added an endorsement for it. Whether yours does is decided by your insurer under your own policy. Check your policy or ask your agent before the cleanup starts, and keep every receipt and photo.
Many people do not find out until they file. Water-backup coverage is often an optional add-on with its own limit, so it is worth reading the declarations page even if you have never had a backup. Flood is a separate policy, so a backup caused by a creek flood would be handled differently.
Take photos before cleanup and let the crew take moisture readings. The crew can document the damage for your claim, and your insurer decides what is paid. If a dispute cannot be settled, the Texas Department of Insurance takes complaints about insurers.
In a slab-on-grade house, the lowest fixtures such as a tub, shower or garage floor drain are where a blocked main line tends to push water out. Without a basement, the waste water spreads across one level, so more flooring and wall base are affected than the same amount of water would suggest.
A clogged toilet or a failed drain can release gray or black water into a bathroom and through its floor edge. The cleanup is smaller, but the same rules apply: porous materials that were wet are generally removed, not dried in place.
Sometimes the blockage is in the service line between the house and the main, or in the main itself. Which side owns the problem is for a licensed plumber and your city or water district to sort out; a restoration crew handles the damage inside the house either way.
Many addresses on rural acreage around Weston, New Hope, Aubrey, Krugerville, Tioga and Gunter rely on septic systems instead of a city sewer line. A failing tank or drain field can push waste water into the house just the same, and the septic professional has to fix the system itself.
Newer subdivisions around Light Farms, Windsong Ranch and Trinity Falls have young landscaping, active construction nearby and drainage that is still settling. That pattern can mean more soil and debris reaching a drain line. It is a general pattern, not a measured fact, and a plumber is the one to check a line with a camera.
Celina buys its treated water from the Upper Trinity Regional Water District, and homes in a MUD or water district such as Savannah's Elm Ridge WCID or Trinity Falls's MUD answer to a different authority for water and sewer service. If a backup traces to a line under the street, ask your city or water district who maintains it.
Older buildings in Downtown Celina and Historic Downtown McKinney can contain asbestos or lead paint. Before cutting walls or ceilings after a backup, ask. Homes built before 1978 fall under the EPA lead renovation rule.
If it's an emergency, call now. For non-urgent sewage cleanup, send the form and we'll call you back.

A standard Texas homeowners policy often covers sudden and accidental water damage, such as a burst pipe, and usually does not cover long-term leaks, flood or sewer and drain backup without an added endorsement.
A small spill from a single toilet overflow on a hard floor can often be handled with gloves, boots and a disinfectant, but anything that soaked carpet, pad or drywall needs removal. If you are unsure, call and describe what is wet. A crew can tell you what can stay.
Usually both. The plumber finds and clears the blockage, and the restoration crew removes the contaminated water, cleans and dries the structure. Calling both early shortens the time between stopping the backup and starting repairs.
It depends on how much of the house was affected. The affected rooms should be sealed off and avoided, and many households choose to stay elsewhere until cleaning is done, especially with infants or someone who is immunocompromised. The crew can explain what areas to avoid.
A lingering smell usually means something porous is still holding contamination, such as pad, a cabinet base or drywall behind the baseboard. Finding and removing it is part of the job. Surfaces are cleaned and the structure is dried.
Any wet building material can grow mold if it stays damp, and sewage-wet material is no exception. Drying promptly limits the risk, but it does not remove it. See the mold inspection page for what happens if mold is suspected afterward.
Yes. A full or failing septic tank or a clogged drain field can push waste water back into the house. A septic professional has to inspect and pump the system. The restoration crew handles the cleanup inside.
