there is not much you can do about....
however drilling and hacking is only allowed for THREE days and MON-FRI 9am to 6pm. IF you hear anymore drilling and hacking after THREE days and on SAT or after that timing you can call HDB to complain. also there should be a license stick onto the wall outside their flat. IT shows the renovation company name and address. But the right thing is to call HDB and not personally call the renovation company.
After the THREE days you will expect some minor noise (knocking of wall tiles to level it when laying, mounting of cabinets with electric drills) but wonx be so jialat like earthquakes. Only here and there and not disturbing if they close the doors. If they DO false ceiling its damn loud like gunshots but it ONLY lasts like 30mins.
but you gotta bear with the noise for today, tomoro and the day after because under the regulations they are allowed to do that.
