My balcony wall has crumbled away and part fallen down, its been 3 months now and they haven done anything about it, is this something I can claim of my Buildings insurance for ? not likely, sounds like due to disrepair.
In theory you should be threatening the management company with action for breach of covenant and getting them to make the repairs. Best to check your lease 1st to see if it is the freeholder's or management companies responsibility to do the repairs, or whether your balcony is demised to you and therefore its your responsibility. there should be a plan in your lease and it will depend on whether there is a red line around the balcony or whether the red line stops before you enter your balcony. the former makes it your responsibility, the latter the management companies.
