Got my flat key last year 20th november, hired a "good friend" to help to do up my 3 room flat. Sign a contract of 27k including kitchen cabinets. (exclude 2 feature wall, 4ft & another is 8ft. a casement wardrobe of 6ft and electrical fee. And I ask my so call "good friend" to quote the carpentry prices and he say need to measure and quote but did not quote out any price at all and he started doing up all the carpentry work and I keep on questioning him on the actual price for the carpentry work as I am afraid it will be over my budget of max 35k and he did not even write out a quotation or contract for me to sign and only say it will be "friend's price". Finished the hse reno end of March and he requested for payment of 30k as I was taking bank reno loan so i just hand him the cheque and I requested him to give me a FINAL quotation for the remaining work. And in August 2011 he billed me $56K and on top of the 30k that i already given him I still got to fork out cash 26k. I did not even sign any contract other than the 27K and when I ask him for a quote first he keep saying the carpenter will measure n calculate (what rubbish is this?) n if he had quoted me a price on the carpentry I would have stop him in doing as its too expensive. And his company call me to say if i am not going to pay up they are going to small claim??? Anybody got experience in handling this? This is my first time reno a flat and thinking that i can trust a friend to do for me and who knows???
