what to do if strata cannot pay for repair of external windows?

Hi. I would appreciate some advice on some trouble I am having. I live in a strata title apartment, in a building built in 1970s. The window frames have “failed” (I tried to upload a picture but not quite sure how to do it on this site: The pictures are quite dramatic). Basically the metal frame has corroded and bits are hanging off. Every time a tradesman is in my apartment for something else they see the windows and say how dangerous they are. Anyone who looks at it sees it is need of repair. As it is, it cannot be repaired and basically the windows need to be replaced. A number of units in my building have same problem, to varying degrees. Some other owners have replaced their external windows at their own expense (and organised it themselves, etc).

my understanding is that external windows are the strata’s responsibility. The current chairman of the executive committee has seen my windows and agrees they need replacing. The problem is the current executive have inherited a situation where there is no money in the sinking fund to cover this. They cant see how they can pay for this. (estimated cost of repairs is $10,000+). The underlying problem is that for a long time these sorts of repairs and upgrades were ignored and there was no money in sinking fund to deal with these sort of contingencies.

I do not want to do what some of the other people in my building have done – in frustration – and gone on to replace their windows themselves.

Am wondering what suggestions people have

many thanks!
