A crack had formed on the concrete floor of her garage and, over the coming months, further cracks appeared around the house and on internal walls. Her garage now has a distinct slope.

At the same time, construction work was occurring over her back fence. Part of an embankment near her property had been removed, which an engineering report found was the cause of the damage.

But 15 months later, no one has been held responsible.

"My insurance tried to get in contact with (the builder), and then they said well, we've done as much as we can, so now it's up to you to actually chase someone up," Ms Bilac said.

She went to Brighton Council and other authorities, but when they discovered who the builder was, they couldn't pass it on to Ms Bilac due to "privacy reasons".

She found out the business herself, emailed as many people as she could, and was eventually told they could not comment "because it's an ongoing insurance issue".

Ms Bilac's only option was having the repairs carried out, but would not have warranty unless the work on the neighbouring property was fixed.

"It's like a vicious circle at the moment," she said.

"I want it to be covered with insurance, that's why we pay insurance for this sort of thing."

The situation had added more stress on Ms Bilac, whose husband was recently diagnosed with cancer.

She said there was clearly a lack of regulation in Tasmania's housing construction sector.

"There should be something put in place with these particular companies that are doing these builds that people like ourselves that are neighbours can go and say, hey, we think that what you're doing there, that's great, but it's impacted on our lives, it's impacted on our property," Ms Bilac said.

"How can we resolve this? What can we do?"

Tasmanian Labor has been calling for a parliamentary inquiry into the building industry to determine regulatory gaps and gauge possible solutions.

Labor building and construction spokesperson Jen Butler said the current regulatory framework was leaving Tasmanians at risk of poor quality workmanship.

"The problem that we find is we just have no understanding of how this job was signed off on in the first place," she said.

"There should have been a proper engineering report, there should have been a property inspector and surveying report, we don't understand how this was actually ticked off, which compromised Bev's garage and is now compromising Bev's home."

Government cabinet minister Sarah Courtney said it was Labor that initially "abolished building warranty insurance".

"It is the Liberal Party that is looking at what we can do to rectify this situation," she said.

"Indeed, we've already strengthened it through TASCAT and the fact that it's cheaper, faster and simpler for Tasmanians to be able to resolve a dispute with a builder and we're looking at what further steps can be taken."
