Is a fire residue survey required by insurers?

Most insurers don’t explicitly require a fire residue survey, but they often recommend it as evidence when there’s a dispute over cleaning or redecoration costs. The survey provides objective data showing what contaminants are present and whether they pose health or corrosion risks.

Without formal testing, it’s difficult to prove how far contamination spread or whether the property was properly restored. For major claims or sensitive environments—like schools, offices, or healthcare settings—insurers often request a residue survey before reinstatement begins. It helps confirm that cleaning efforts were effective and no secondary damage remains.
