'The bodies are on the piles of rubbish completely covered in the fluid that comes out': The day-to-day horrors witnessed by the man who has to clean up some of Australia's most squalid homes

• e-mail

A professional cleaner who mops up after extreme hoarders has told of the disgusting conditions he comes across almost on a daily basis. 

Josh Marsden, who runs Biohazard Trauma and Crime Scene Cleaning, has shared photographs from inside the houses he cleans up with Daily Mail Australia.

The pictures document some of the worst houses in the nation, littered with piles of rubbish, mountains of food scraps and stacks of newspapers covered in faecal matter the company is forced to clean.

In some photos, evidence of where someone has died in the middle of the filth is obvious.

Mr Marsden assesses how dirty a house is on a scale of one to 10.

Homes that fall into the rating one category are those lived in by basic hoarders who collect a lot of things, whereas a rating of 10 means there is so much filth in the house that you cannot see the floor, which is often also covered in animal faeces and infestations everywhere.

For a three-bedroom, one-bathroom home, cleaning up can cost up to $20,000 if it scores a rating of 10.

'It usually would take three technicians two weeks to clean a home that’s rated a 10,' Mr Marsden told Daily Mail Australia.

'A 10 has animal faeces, bug infestations... [people are] just throwing rubbish everywhere, and food scraps get put in a pile. 

In extreme circumstances, employees wear Tyvek suits to protect themselves from hazardous dangerous of their jobs

'I would rather live at the tip than live in some of these houses. At least the tip has fresh air.' 

One of the signs Mr Marsden sees that indicate a hoarder is gumboots left on the back step.

He said people who had extreme tendencies would use the footwear to wade through their out-of-control homes.

Mr Marsden said he would service houses with the rating of 10 every fortnight and three to four houses between a one and six every week. 

He said cleaning up after hoarders was worse than mopping up unattended deaths, where people die of unnatural causes.

This was the scene of an unattended death where a body was found lying in the middle of rubbish

Mr Marsden said most unattended deaths involved hoarders because most were ashamed to let people into their homes

But sadly most unattended deaths involved hoarders who were 'embarrassed or ashamed' to let people visit their homes. 

'The bodies tend to be on the pile of rubbish. The rubbish is completely covered in goop and bodily fluid and faeces and everything that comes out a body.

Cleaners are often met with two feet deep of rubbish along with caked on faecal matter on the floor

Mr Marsden's clients range from those who have mental health issues to drug addicts and alcoholics

This is when a house reaches a level three on Mr Marsden's ratings system, with grime and dirt caked onto the kitchen bench

'Floorboards often are rotten underneath because of the filth that grows underneath. 

'Cats and dogs that live there p**s and crap everywhere. They usually live on the couch because there's nowhere else for them to go.'

Mr Marsden's clients range from those who have mental health issues to drug addicts and alcoholics.  

Most people would think the filth would be the most difficult to deal with but he insists it's the hoarders who did not want to throw anything out.

This shower has an major mould and limescale problem that has remained uncleaned for a long period of time

'We won't clean the property if the owner is present during the clean,' Mr Marsden said.

'We tell them to buy a box of stickers and go around and sticker everything with a red or green dot if they want to keep. Anything that's not stickered gets thrown out.'

Despite the nature of the job, Mr Marsden said there was no shortage of candidates looking to break into the industry.

'We get calls every week from people wanting jobs. Everyone wants to be a crime scene cleaner because they see it on TV shows and think it's a cool job,' he said.
