A sewer overflow can leave more than just a visible mess. Contamination can spread across flooring and surrounding surfaces, requiring thorough cleaning and sanitisation before the affected area can be safely restored.

At a strata apartment building in Cronulla, NSW, High Demand Restoration attended after a sewer overflow affected a garage area. The affected carpet also required removal as part of the clean up works.

Cleaning Up After the Sewer Overflow

Our team began by addressing the gross contamination across the affected garage area.

Wet vacuuming and washing techniques were used to remove the contamination before the exposed slab was sanitised using a commercial grade disinfectant.

Cleaning was also carried out beneath the kitchen cabinetry where access was available.

Some sections beneath the cabinetry could not be thoroughly cleaned due to access limitations, which was documented following the works.
