I have also engaged defong, Id is kevin tan. So far, I have finished my tiling, shower screen, painting, false ceiling, lightings n mirror installation. Overall, I'm very satisfied with their services. Firstly, I loved kevin's 3D. It was pretty creative n suited my demands. Second, he is price negotiable, third he is upfront n will advise u on pros n cons of every item. Workmanship remarks Their aircon concealation was pretty superb, can't see much of the trunkings, painting colors r boldly striking but **** chio. also spotchk them a few times, n they r norm busy hacking away n doing wk..friendly stuff. Now waiting for my feature wall n kitchen cabinet haha
