Sewage cleanup in Lakewood, CO
Sewage backup cleanup, treated as the biohazard it is
Category 3 water carries pathogens and waste into your home. One local team contains it, removes what it ruined, sanitizes to hospital grade and restores the space, across Lakewood and Jefferson County.
A sewer backup is a health hazard, not a cleaning job
Sewage backup is classed as Category 3 water, the most contaminated grade. It carries bacteria, viruses and waste that soak into drywall, carpet, pad and subfloor within hours. Porous materials that touch it cannot be cleaned and reused, so they have to come out.
In Lakewood, most backups start at an aging sewer lateral or a basement floor drain, often during spring melt or a heavy summer storm when the public main surcharges. The lowest fixture overflows first, which is why finished basements take the worst of it. If yours has flooded, the flooded basement cleanup process overlaps with everything here.
- Pathogens, not just dirtCategory 3 water carries E. coli, hepatitis and other pathogens. Removing it safely needs containment, protective equipment and antimicrobial treatment, not a wet vac and bleach.
- Porous materials have to goCarpet, pad, drywall and insulation that absorbed sewage are removed and disposed of as contaminated waste. Sealing over them traps the hazard inside the wall or floor.
- A lingering smell means it is still activeOdor after a backup usually means contamination is still present in materials or wall cavities. We treat the source, not just the air.
- It rarely stops at the floorSewage wicks up walls and tracks under flooring. Moisture mapping shows how far it traveled so nothing contaminated gets closed back up.
Before we arrive: keep people and pets out of the affected area, stop running water and flushing toilets that drain through the backup, and switch off power to the area at the breaker only if you can reach it without standing in the water. Do not try to clean Category 3 water yourself.
How a sewage cleanup runs
Four stages, handled by one team from the first containment sheet to the final clearance.
- 1
Containment and assessment
We seal the affected area to stop cross-contamination, then map how far the sewage spread using moisture meters and, where needed, inspection of wall cavities and the subfloor. Nothing is torn out before we know the full extent.
- 2
Removal and extraction
Contaminated water is extracted and the porous materials that cannot be salvaged are bagged and removed as regulated waste. Salvageable contents are set aside for cleaning rather than thrown out by default.
- 3
Sanitizing and drying
Every remaining surface is cleaned and treated with hospital-grade antimicrobial, then dried with air movers and dehumidifiers until moisture readings return to normal. This is the step that clears the smell for good.
- 4
Restoration and clearance
We rebuild what came out, drywall, flooring and trim, and confirm the space is dry and sanitized before you use it again. The same crew that handled the cleanup finishes the water damage repair in Lakewood, so there are no hand-offs.
What causes sewer backups in Lakewood
Knowing where backups start is how we trace the source rather than just mopping up the symptom.
- Aging sewer lateralsClay and cast-iron lines under older Lakewood homes crack, sag and fill with roots. A blocked lateral sends everything back toward the lowest drain in the house.
- Main line surcharge in stormsHeavy runoff off the foothills can overload the public sewer. When the main is full, waste pushes back through basement floor drains and ground-floor fixtures.
- No backwater valve fittedHomes without a backwater valve have nothing to stop a surcharged main from forcing sewage inside. Fitting one is the single most effective step after a backup.
Sewage cleanup in Lakewood: your questions answered
Is sewage backup dangerous?
Sewage backup is dangerous because it is Category 3 water, carrying bacteria, viruses and parasites that cause serious illness. Keep people and pets away from the affected area and avoid contact until it has been professionally contained, removed and sanitized.
Can I clean up a sewage backup myself?
You should not clean up a sewage backup yourself. Household cleaners and a wet vac do not remove the pathogens or the contaminated porous materials, and disturbing the water spreads it further.
Safe cleanup needs containment, protective equipment and antimicrobial treatment. The materials that absorbed the sewage usually have to be removed and disposed of as regulated waste.
Does homeowners insurance cover sewage backup?
Homeowners insurance usually does not cover sewage backup unless you carry a specific sewer or water backup endorsement. Standard Colorado policies exclude backups from sewers and drains, so check for that add-on.
We document the loss in full with photos and moisture logs and bill your insurer directly where cover applies. More on what Colorado policies cover.
How long does sewage cleanup take?
Most residential sewage cleanups take two to five days from containment to a dry, sanitized space, with reconstruction on top of that. The timeline depends on how far the sewage spread and how much porous material has to be removed and rebuilt.
What should I do first after a sewer backup?
First, keep everyone out of the affected area and stop using any water that drains through the backup. Switch off power to the area if you can do so safely, then call for cleanup.
The sooner containment starts, the less the contamination spreads into walls, flooring and adjoining rooms.
