The first hour when sewage backs up in Fairfax
Fairfax County publishes its own advice on who to call for a sewer backup. This sequence uses it for the third step and adds what a cleanup crew needs from you.
Keep everyone out and stop adding water
Keep people and pets out of the affected rooms. Do not run taps, washers or dishwashers, and do not flush toilets that drain toward the backup, because that only adds volume.
Make the power safe
If the backup is near outlets or the panel and you can reach the breaker without stepping into water, turn off power to the area. If you cannot, leave it alone and call.
Find out whose pipe it is
If you think the problem is in the county main, call Fairfax County's 24-hour Customer Communications Center at 703-323-1211 before you call a plumber. If the backup happens only when a fixture in the house is used, the blockage may be in your own line.
Call for the cleanup
Call 1-888-293-5663. Sewage is Category 3 water, so a crew arrives in protective equipment, contains the area and starts removing standing water and contaminated materials.
Photograph, then leave it alone
Photograph the damage and the affected belongings for your own records before anything is moved. Do not mop or treat porous materials with household cleaner.
The county main, your lateral and the lowest drain
A sewage backup in Fairfax usually arrives at the lowest drain in the house: a basement floor drain, a shower or a toilet. The cause is a blockage downstream. In the older neighborhoods of Mantua, Kings Park and Canterbury Woods, mature trees and aging laterals make root intrusion a common one, a slow growth that blocks the line entirely years later. Other causes are a failed ejector or sump pump serving a below-grade bathroom, and heavy rain overloading the system.
Fairfax County's wastewater page draws the line this way. If the county line is operating normally, the likely cause is the private building sewer lateral, you will be advised to call a plumber, and maintaining a private lateral is the property owner's responsibility under County Code 65-6-1. The service line from the house to the county sewer, including the connection to it, is the property owner's to resolve.
What cleanup involves in a finished Fairfax basement
Most Fairfax basements are finished, with carpet and pad, drywall, insulation and built-ins that sewage soaks into. Those porous materials cannot be decontaminated in place, so they are removed and disposed of as contaminated waste. Standing sewage and solids are extracted, the structure is stripped back to surfaces that can be cleaned, and framing, concrete and subfloor are treated with EPA-registered antimicrobials while HEPA air filtration runs.
Then the structure is dried to documented moisture standards, because a decontaminated but damp basement grows mold and holds odor. You receive documentation of the disposal, the antimicrobial treatment and the drying. Once the backup is cleared, a camera inspection of the lateral is what tells you whether it will happen again.

Frequently asked questions
Who do I call if sewage is backing up in Fairfax, VA?
If you think the problem is in the county main, Fairfax County says to call its 24-hour Customer Communications Center at 703-323-1211 before a plumber. For the contaminated-water cleanup inside the house, call Restoration Doctor at 1-888-293-5663. If the county line is working normally, a plumber is the next call for your own line.
How fast can you get to a sewage backup in Fairfax?
Dispatch runs 24 hours a day, and sewage contamination worsens by the hour, so call as soon as the area is safe. We can be on-site in as little as 60 minutes across the Northern Virginia core. Response times vary based on crew availability and demand.
Whose responsibility is the sewer lateral in Fairfax County?
Fairfax County's wastewater page says maintaining a private lateral line is the property owner's responsibility, and that the service line from the home to the county sewer, including the connection, is the property owner's to resolve. Ask the county's 24-hour center to check whether its main is running normally.
Can my carpet and drywall be saved after a sewage backup?
Porous materials that sewage has soaked, such as carpet, pad, drywall, insulation and particleboard, must be removed and disposed of as contaminated waste. Framing, concrete and subfloor are cleaned, treated with antimicrobial and dried.
Can I clean up sewage myself?
It is a poor idea. Sewage is Category 3 water that can carry bacteria, viruses and parasites, and safe cleanup needs protective equipment, containment, proper disposal and EPA-registered antimicrobials, not household cleaner. Keep children and pets out until a crew has finished.
Who is the best sewage cleanup company in Fairfax, VA?
No neutral ranking of Fairfax sewage cleanup companies appears on this site, and we do not say we are first. Ask each company whether it removes porous materials, what it treats surfaces with, how it dries and documents the result, and for a license number you can look up. Ours is Virginia DPOR Class A contractor license 2705191604.
