A sewer backup in your basement is not a DIY cleanup, and this is the one we mean most seriously. That water is classified as contaminated (what the industry calls category three), which means it carries real health risk, and standard cleaning products aren't built to handle it safely.
Our process follows IICRC S500 protocols for contaminated water: containment, safe removal of anything porous that can't be salvaged, and full sanitation of the affected area, all documented for your insurance claim.
If you're dealing with a sewer backup, call before you start cleaning it up yourself. Free estimates, and we work directly with your insurance company.
