Dear Khun Richard,
The quotation send to you base on contractor opinion. After inspect again today I suspect that the leak in the bathroom are not from the upper condo pipe because I saw cracks on the concrete slab therefor I think we need to do a foam injection.
The leak coming through the ceiling is coming from the master bedroom veranda I will open up the ceiling to inspect and will update you later.
For the insurance claim we already submitted they will come to inspect and let us know if can claim or not.
