Hi all, For those who are using wireless doorbell, can i know how long can the batteries last each time? And any good wireless doorbell to recommend?? Thanks in advance.

Does anyone know how to remove the dampness inside walls. A leakage in one of my bathroom pipes had caused water to seep through the walls. The dampness is rather serious and there is visible dampness stains which is spreading around the MBR. The 'dampness level' on the walls is also rising even though the leakage problem is already fixed. Can anyone help or recommend any company that provide wall drying service?? cos i cant seem to find any on the internet. Thks
