A family was forced to leave their house in Broomfield after they found that meth residue made the place 'non-inhabitable.'

It was an addiction, kept hidden in the basement of Robert Haugen's childhood home.

"There was a day back in August where my brother was having hallucinations, acting delusional," Haugen said.

Haugen's brother had been living in the basement of their parents' home. His meth problem was a secret no one in the family knew.

"To see my mom go through this. It's heartbreaking," Haugen said. "My dad has dementia so he's not really aware of what's going on."

When his brother went to treatment, Haugen and his wife moved in to help out his parents. Shortly afterward, Haugen's wife started to get sick.

"Came to the conclusion that she may have been sick because of the meth residue in the house," Haugen said.

His home is no longer familiar, covered with tape and plastic, surrounded by guys in hazmat suits working 10 to 12 hours a day to gut the place.

Haugen estimates it will cost his family about $150,000.

"My parents have had to cash in certificates of deposit, tap out their life savings just to afford the remediation process," Haugen said.

Haugen wanted to share his story to let people know that it could happen to anyone.

"These things happen in any community, any neighborhood," he said. "It's really tough...nobody should have to see their house like this."

Haugen's parents are having the meth cleaned out to state standards. If an inspector signs off, they would not have to disclose the meth contamination to a potential home buyer under Colorado law.

However, it will always be in a public file.
