Black-Water Cleanup for Businesses and Property Managers
A sewage backup interrupts operations, creates health risk for employees, tenants, and customers, and exposes the building to long-term moisture damage if it is not handled correctly. Raw sewage is category 3 black water under the IICRC standard. It cannot be mopped up. The affected area has to be contained so the contamination does not spread, the water and solids extracted, porous materials that cannot be disinfected removed, every surface cleaned and sanitized, and the structure dried and documented.
RestorePro has done this work for offices, retail spaces, restaurants, schools, industrial spaces, apartment buildings, condominiums, and property management teams across Eastern Massachusetts since 1997. We work around your hours, keep the affected area isolated from the rest of the building, and give you the photo documentation and reports you need for the insurance claim and for your own property records.
Commercial Sewage Problems We Handle
- Sewer main and drain line backups — Floor drains, restrooms, kitchens, and utility rooms.
- Restaurant and food service backups — Kitchens and dining rooms where health codes require thorough disinfection before reopening.
- Apartment and condominium buildings — Common areas, basements, and individual units, with communication to tenants and the association.
- Offices and retail — Restrooms, break rooms, and storage, cleaned so staff and customers can return.
- Schools, churches, and public buildings — Large areas with high occupancy and strict sanitation expectations.
- Industrial and warehouse spaces — Loading areas, floor drains, and lower levels.
- Contents and inventory — Sorting what can be disinfected from what has to be disposed of, with an inventory for the claim.
What To Do Right Now
Sewage is black water and should be handled as a health hazard until it is contained.
- Keep employees, tenants, and customers out of the affected area and post it as closed.
- Stop using water in the affected part of the building: no restrooms, sinks, or floor drains.
- Shut off power to the affected area at the breaker if water is near outlets or equipment.
- Shut down HVAC serving the affected area so contaminated air does not move through the building.
- Photograph the area from the doorway for the claim and call your insurance carrier.
- Call us. We dispatch 24/7 and can usually be on site the same day.
What not to do
- Do not allow employees or tenants to walk through the affected area.
- Do not run fans before the contaminated materials are contained. Moving air spreads bacteria.
- Do not have janitorial staff mop it. Ordinary cleaning does not disinfect, and it contaminates the equipment.
- Do not reopen the space to the public until it has been disinfected and dried.

Commercial Sewage Cleanup FAQ
How quickly can we reopen?
It depends on how much sewage, how far it spread, and how much porous material has to come out. We contain the area first so the rest of the building can stay open where that is safe, and we give you a realistic timeline after the inspection.
Do you work nights and weekends?
Yes. We answer and dispatch 24 hours a day, 7 days a week, and we schedule the work around your operating hours when the situation allows.
Is a sewage backup covered by commercial insurance?
Often only with a water or sewer backup endorsement on the policy. We document the cause, the extent, and the materials removed so the claim is as strong as it can be.
What documentation do we get?
Photo logs, moisture readings and dry logs, an inventory of removed materials and contents, and an itemized scope of work. Property managers use these for the carrier, the owner, and the tenants.
Can you keep the rest of the building open?
In most cases, yes. Containment barriers and negative air isolate the affected area so adjacent spaces can keep operating.
Do you also do the repairs?
Yes. RestorePro holds Massachusetts construction supervisor licenses. Flooring, drywall, and finishes that come out are put back by our own crew.
