Can i make a point clear before this gets out of control?
ANY defect to a private property be it Build or after build is NOT the responsibility of the Presidents. or the Administrator.
The Presidents and Administrators role are to ensure that your Community fees i.e. the Budget are spent wisely and do not go over Budget, these fees are used to maintain common areas.
Defects to private property is the responsibility of the Owner and the Builder
Probably the best way to get Polaris to fix any building defect is to get a Solicitor involved.
In this instance it would not cost much to replace a few tiles, I know we should not have to do this but it is probably the best, quickest and cheapest option.
Perhaps all owners with damaged tiles can form a group count no of tiles contract someone to replace and divide cost by tiles?
