Hi, I have been sourcing for contractors/id for my new flat. A contractor who is highly recommended in this forum quoted me $900 for haulage and debris removal. When I queried why was it so expensive, his email reply was "it best u can call up HDB to find out out yourself, unless yr r laying lamainted floor or prquet for whole unit, Then you can ask HDN to uplaod the sand and cement materials for u , Because HDB provide free cement screening for New BTO flat". I would like to know should I really be doing this? Ain't contractor suppose to liaise with HDB on my behalf? Any advice is much appreciated.
