Years Experience

Projects Completed

Biohazard Remediation

Sewage clean-up, hoarders, human and animal waste, blood and trauma clean-up, vomit – Don’t be embarrassed when confronted with this unpleasantness. Here at CSS, we’ve seen it all.

Mould Removal

The presence of mould is not always obvious. Mould may exist behind wall lining and in roof spaces for some time causing residents continued respiratory discomfort and only become evident when the spores penetrate surfaces and discolour facings.

Asbestos Removal

From a broken soffit through to larger projects such as emergency work – fire or vehicular damage; cladding, roofs or ceilings in schools, factories, or warehouses and soil clean-ups.

Flood & Water Damage Remediation

Flood damage needs to be treated promptly and professionally.

Odour from mould and mildew accumulation can have an unpleasant effect in your home as well as creating a health risk.

Fire and Smoke Damage Remediation

Due to the unique behaviour of fire damage and smoke, fire restoration may not be simple, so it’s important to have an experienced restoration team on your side. A fast treatment will help reduce smoke and soot health hazards if completed within 48 hours.

Lead Paint Removal

Paint removal is a messy job however when you are removing lead paint you really need to be aware of of the dangers involved as you try to minimise the mess!

Meth and Chemical Remediation

CSS personnel have been working in this area of meth clean up for 15 years and have undertaken extensive study into producing industry standards and establishing a proven Meth Lab Decontamination System.

We had a sewage leak at work which leaked into 3 bathrooms, a cleaning cupboard and a kids' play area. I phoned CSS and within a couple of hours, they were onsite to remove all the contaminated items and to completely sanitise and deep clean. The play area wasn't easy - it took a lot of effort to rip up the very thick rubber safety matting. I can't recommend CSS enough. Because of their excellent service and quality of their work, we were up and running again with minimal disruption. They worked late into the night to ensure that all was ready for the morning. Thanks team - your professionalism and outstanding results took a lot of stress out of what was a trying time for us.
