Sewer backup cleanup in Pittsburgh, PA
Sewer backup cleanup starts with a bad discovery: water coming up out of your drains instead of going down. Usually it is the basement floor drain, because a blocked or overloaded line pushes sewage back through the lowest opening in the house. In this region it happens most in heavy rain. Pittsburgh's combined sewers carry stormwater and sewage in the same pipes, and wet weather can push them past their limit.
We clean up after exactly this, all year. Un-Flood-It answers 24/7 from Tarentum and gets to your door in 2 hours or less. This page is part of our sewage cleanup work. Call (412) 226-9468 first, then read on.
What does sewer backup cleanup include?
Sewer backup cleanup is the safe removal of sewage that backed up into a building, plus the disinfection and drying that make the space usable again. It runs in five steps:
- Contain the affected area so contamination stops spreading.
- Extract the standing sewage and debris with industrial pumps.
- Remove soaked porous materials that cannot be made safe.
- Clean and disinfect every surface the water touched.
- Dry the structure and verify it with moisture readings.
Fixing the pipe itself is a plumber's job, and a cleanup crew should tell you that plainly.
If it is coming up right now, call (412) 226-9468. We answer at 3 a.m. too.
Why sewers back up in Pittsburgh houses
Four causes show up again and again, and the Insurance Information Institute's rundown of sewer backup causes matches what we see in the field:
- Old lines. The nation's 500,000-plus miles of sewer pipe average over thirty years old.
- Combined pipelines. Storm and sanitary water share pipes here. Hard rain can overload them.
- Tree roots. Roots work into cracks and pipe joints, then grow until the line chokes.
- City main blockages. When the main blocks, sewage can back into homes through floor drains.
The last one matters. If water is rising fast from the floor drain, report it to the city public works office too. Your house may be the symptom, not the cause.
Keep everyone away from the water
Backup water is Category 3, the most contaminated class of water loss. It can carry E. coli, Giardia, and Hepatitis A. Keep children and pets out of the area, and stay out of it yourself as much as you can.
Two things to do before we arrive: stop using water upstairs, and stay off wet floors near anything electrical. Every flush, shower, and laundry cycle exits through the same line, so using water feeds the backup. And sewage is corrosive; it starts working on flooring, drywall, carpet, and subfloor the moment it lands. Waiting a day is not a neutral choice.
Water where it should not be?

How we clean up a sewer backup
Containment comes first: we seal the work area before pumping starts. Then extraction with high-powered pumps, removal of what cannot be saved, and disinfection with hospital-grade antimicrobial agents. Drying comes last, and we prove it with thermal imaging and moisture detection tools instead of calling it dry by eye.
You may have seen our trucks in bad weather already. When the January 25, 2026 snowstorm burst pipes across the region, our crews worked flooded homes through that stretch, including a multi-pipe residential loss a customer reviewed that February. Wet-weather weeks are also when the combined sewers surcharge, so backup calls and storm calls tend to arrive together.
One honest boundary: we do not repair sewer lines. Plumbing is out of our scope, and we refer line work to a plumber while we handle the contamination, cleanup, and drying.
The insurance side, documented from hour one
A sewer backup claim is won or lost on the record. We photograph the loss before cleanup starts, log what was removed and what was cleaned, and hand your adjuster a file that answers questions before they ask. Then we bill your insurance company directly — the same promise that sits on the front page of our website.
Basement losses have their own wrinkles, from floor drains to what can be saved. We cover those on our basement sewage backup page.

Keeping it from happening again
The fix that actually prevents round two is a backwater valve: a fitting in the sewer line that lets sewage go out but not come back in. Property owners are responsible for installing and maintaining it, and for the sewer lateral itself — the pipe that runs from your building to the city main, even the part under the street.
We will tell you what we found in your line's behavior while we worked. The valve and lateral work itself goes to a plumber, and we will say so on site rather than sell you something we do not do.
Frequently asked questions
Is a sewer backup an emergency?
Yes. The water is Category 3 and it is corrosive, so both the health risk and the repair bill grow while it sits. Contain it and get cleanup moving the same day.
Can a sewer backup make you sick?
It can. Backup water can carry E. coli, Giardia, and Hepatitis A. Keep people and pets away from it, and leave the removal to a crew with protective gear.
Does insurance cover sewer backup cleanup?
Your policy controls, and backup damage often needs coverage that was added to the policy. Whatever your answer is, we document everything and bill your insurance company directly.
Who fixes the broken pipe?
A plumber. We do not do line repair. We clean up the contamination, disinfect, and dry the structure, and we refer the pipe work out honestly.
How fast can you be here?
At your door in 2 hours or less. We answer 24/7, 365 days a year, from our Tarentum shop.
