Hi Kerio,
I'm sorry to hear the unpleasantness on your reno and my condolences to you..
Actually why didn't your ID put those floor protection covers during the reno? Has it been taken off already? You should request them to put it there to protect the flooring especially laminates... if it is homogenous tiles at least there is the chemical wash... but laminates, if I'm not wrong, cannot be chemical washed.
anyway... hope your reno will progress smoothly.. btw I'm oso from punggol forum (future residence of Damai Grove)... now researching stuff on renovation
