- Cleaning and sanitizing of salvageable furniture, appliances and stored belongings
- Sanitizing after sewage reaches concrete slabs, tile grout and unfinished basement walls
- Raw sewage removal from floors, basements, crawl spaces, garages and utility rooms

Sewer Backup Questions Answered for Alviso, San Jose, CA
How do I know if sewage is leaking under my house?
Common signs include a sewer smell in the yard or crawl space, soft or damp ground near the foundation, gurgling drains and slow drains in several fixtures at once. A plumber can confirm the leak. Once it is found, a cleanup team can take care of the contaminated soil, materials and odor.
Should I call a plumber or a cleanup company first?
If sewage is still coming up, a plumber may need to stop the source. If sewage is already on the floor, a cleanup team can start containing it at once. Many property owners call both, and it does not matter much which is first. Sewer backup companies and plumbers often work one after the other on the same job.
How do I disinfect a basement after a sewer backup?
After the sewage and soaked materials are out, floors and walls are scrubbed with a cleaner, then treated with an EPA-registered disinfectant used by label directions. Unsealed concrete can hold odor and needs extra attention. Crews often handle this step with professional equipment.
What if sewage backs up through a shower or tub?
Treat it as raw sewage. Keep people out of the bathroom, stop using the fixture and call for cleanup. The liquid can reach under flooring and into walls, so a crew checks beyond the visible puddle.
How long does sewage cleanup take?
Small jobs may be finished in a day, while larger ones with tear-out, drying and odor treatment take longer. The time depends on the area affected and what had to be removed. The crew can tell you what to expect after assessing the space.
Is sewage cleanup the same as water damage restoration?
No. Water from a clean source can often be dried in place, but sewage is a biohazard that requires removal of contaminated materials and disinfection. Drying alone does not make a sewage-affected space safe.
