"A lot of people feel its the last option, people need to move on. We can't be dealing with this for the next ten years," said another.
Mica-affected homeowners are going down the legal route because the feel like they've no other option.
Dave Coleman, Principal of Coleman Legal commented: "This case is being brought by the families that have suffered under what's commonly called the Mica Scandal.
"Well what the homeowners are doing is they're seeking to recover the difference between whatever the grant is and whatever their losses are as a result of this problem - from the defendants in the case," he said
The case is being funded by Defective Blocks Ireland, which has been set up by two Donegal businessmen.
To date, 500 homeowners have signed up to this case as plaintiffs and many more are set to follow suit.

One homeowner said, "not only are you losing your home on a temporary basis while you get it remediated, we have to get another place somewhere, and that's problematic because there's nowhere else to go."
Another is worried she will be "putting up tents," for her family.
