Quick answers
- Stop using all fixtures that share the line — more water makes it worse.
- Keep people out of sewage; bag and discard contaminated items carefully.
- Call (703) 214-2551 — phones answered 24/7, never voicemail.
- Photograph the backup for insurance and your landlord before cleanup if safe.
When to use this checklist
Use it the moment sewage or wastewater appears on a commercial floor, or multiple restrooms/kitchens back up together.
Immediate steps
1) Stop fixture use. 2) Keep staff and customers out of contaminated areas. 3) Shut off water at the local or building shutoff if flooding continues. 4) Call us and your property contact. 5) Do not run chemical openers into standing sewage.
What we need when you call
Business name and address, which fixtures are affected, whether sewage is present, after-hours access instructions, and any known cleanout locations.
After we clear the emergency
We explain whether this was a fixture, branch, or main issue and what permanent repair options look like in flat-rate terms — including camera findings when we ran one.
Failure modes to avoid
Keeping the doors open over standing sewage
Health-code and slip risks escalate fast. Close the affected area until it is safe.
Only clearing without documenting the cause
You’ll be back in the same emergency. Ask for camera evidence on repeat backups.
