A Metro Vancouver home builder says the multi-million dollar home he's been building for six months has been ruined by paint-bearing vandals.

Bill Czinege, the project manager for Apex Western Homes, says he walked into the home he's been helping to build in North Vancouver on Tuesday morning and discovered litres of paint strewn across the interior of the home.

Floors, walls and even the fridge and stove had painted covering them.

"They purposefully hit every room, every piece of carpet, every appliance, every piece of plumbing fixture. They put paint on everything," Czinege told CTV Vancouver. "They were meaning to do destruction and accomplished that."

North Vancouver RCMP says the damage is estimated to cost the company over $80,000 and that figure could rise.

Mounties say this type of incident is highly unusual and the motive behind it is currently a mystery.

However, they say they paint cans left behind have finger prints on them and the paint strewn across the floor preserved several footprints.

"Somebody's out there with paint on their clothes or their hands and in all likelihood on their shoes," said Cpl. Richard De Jong.

The property was set to be put on the market just after Labour Day weekend but the company building the home says the paint damage has pushed back that date for at least six weeks.

Dennis Doherty, the company's general manager, says the company is discussing the incident with an insurance agency to help cover the cost of damages, but it remains a disheartening experience.

He says the company has noticed several minor examples of vandalism -- mostly involving yard work -- but this is a much more serious and shocking example.

"You can see the light at the end of the tunnel and then you walk in to this," he said about having the home wrecked so close to completion. "That's why I felt shock when I walked in."

The site in North Vancouver, as well as others, will have onsite security as well as video cameras moving forward to help deter other vandals, he added.
