Sewage Backup Cleanup in Flagstaff

Sewage in a basement, bathroom or crawl space is not a mop-and-bucket job. It carries bacteria and viruses, and everything porous it touches has to come out. Mammoth Restoration answers the phone 24 hours a day, is on scene in Flagstaff in under 2 hours, and handles the whole job: pumping it out, removing what can’t be saved, disinfecting, drying and rebuilding. Call 928-714-0050.

What to do right now

1. Keep people and pets out of the affected rooms. Don’t walk through it and track it into clean parts of the house.
2. Stop using water. Don’t flush toilets, run sinks, or start the dishwasher or washing machine until the blockage is cleared. Every gallon you send down the drain can come back up.
3. Turn off power to the affected area at the breaker if you can reach the panel without stepping in water.
4. Don’t run household fans or the furnace blower over it. Moving air spreads contamination through the house.
5. Take photos from a dry spot before anything is moved. Your adjuster will want them.
6. Call Mammoth. We’ll tell you on the phone what to shut off and what to leave alone until we get there.

Why sewage is different from other water damage

The restoration industry sorts water into three categories. A burst supply pipe is Category 1, clean water. Sewage is Category 3, the worst, sometimes called black water. With clean water, carpet and drywall can often be dried in place. With sewage, they can’t. Carpet, pad, drywall, insulation and anything else porous that the sewage touched is removed and disposed of, and the framing, concrete and other hard surfaces left behind are cleaned and disinfected before any drying starts. That is why a sewage backup takes more labor than a clean-water leak of the same size, and why it shouldn’t be handled with a shop vac and bleach.

What causes sewage backups in Flagstaff

• Tree roots growing into older sewer lines, the most common cause in established neighborhoods.
• A collapsed, cracked or bellied line between the house and the street.
• Grease, wipes and other things that shouldn’t go down a drain building up into a clog.
• A full or failing septic tank or drain field, for homes outside city sewer service.
• Heavy monsoon rain or fast snowmelt overloading the system and pushing water back through floor drains.

What we do when we arrive

• Contain the area so contamination doesn’t spread to the rest of the building.
• Pump out standing sewage and remove solids.
• Remove contaminated carpet, pad, drywall, insulation and other porous materials, bagged and hauled off properly.
• Clean and disinfect the framing, subfloor, concrete and every hard surface that was exposed.
• Dry the structure with commercial air movers and dehumidifiers, checking moisture readings until it’s dry.
• Document everything for your insurance claim, with photos, moisture readings and a written scope.
• Rebuild. Our reconstruction crew replaces the drywall, flooring, trim and paint so you deal with one company.

The backup has to be fixed at the source or it will happen again. Our water mitigation team dispatches 24/7 to stop the damage and start cleanup. Mammoth Plumbing clears or repairs the line during business hours, and we coordinate the two so you make one call.

Will insurance cover it?

It depends on your policy. Many standard homeowners policies exclude sewer and drain backups unless you added a water backup endorsement, which is usually an inexpensive add-on. Check your declarations page or call your agent and ask specifically about “water backup and sump overflow” coverage. Mammoth has worked with more than 50 carriers and bills the carrier directly for covered work. Whether or not it’s covered, we give you a written estimate before work starts and an initial assessment report within 12 hours.

Sewage backup FAQs

How fast can you get to a sewage backup in Flagstaff?

Under 2 hours, 24 hours a day, including weekends and holidays. Winter storms can stretch that; we’ll give you a real ETA on the phone.

Can I clean up a sewage backup myself?

A small overflow on tile that you catch right away, yes, with gloves and disinfectant. Anything that reached carpet, drywall, a finished basement or a crawl space, no. Sewage soaks into porous materials where surface cleaning can’t reach it.

Do I call a plumber or a restoration company?

You need both: a plumber to clear the line and a restoration crew to clean up what came out of it. Mammoth does both and coordinates them.

Can my carpet be saved?

Not if sewage reached it. Carpet and pad contaminated by Category 3 water are removed and replaced.

Is it safe to stay in the house?

Usually, if the affected area can be closed off from the rooms you’re living in. We’ll tell you honestly when we see it. A backup that reached the main living space or the HVAC system is a different situation.
