For fellow locals who are looking at Defong as a contractor, here's my experience with them. It took me quite a while, before I decided to go ahead and make this post. Sealed the deal to renovate my house about 8 months back. My new house is situation in Yishun. This was after some filtering. I decided on him as he sounded sincere. In Feb this year, renovation started. It took Mr. J about a few days to send me the 3D drawings. Indeed, my expectations were not high, as I feel that at such a competitive pricing, I think 3D drawings would have been a plus. Indeed, if my guess is not wrong, he basically modified from existing drawings, and send me mine, claiming that he 'drew' it. When renovation started in Feb this year, he failed to coordinate certain aspects of my renovation, such as adding extra power points. Then, in order to cut costs, minimal cardboard protection was used to protect my stuff such as walls and doors. Hence, my walls and doors sustained significant damage. In spot checks conducted, several stuff promised were not delivered. I shall not be too specific here. Several patch up works that were supposed to be executed, were not done. faults were then concealed using carpentry works. Renovation took about 1 month to complete major works. In Mar, I started to detect some defects in the works, and updated the coordinator in charge personally. After 5 weeks, only approx 10% of the faults were rectified, though there were constant promises that it will be rectified within 1 week. I will update more details gradually, when the time is right. My wife and I both agreed that, if we were to renovate our house again, this company will be not even be in out shortlist. For readers who feel I opened this account to flame this particular company, please be aware that there's 1001 contractors in Singapore, and there's no reason why I highlight this company to write a negative review. Rather, my writeup is to alert fellow locals that, internet reviews (positive ones) can be debatable. If you are looking to engage Defong, do so at your own risk. Learnt my lesson.
