I engaged an ID, the initial quotation came up to be about 40k although I told him my budget was 20k. Halfway through the renovation, he billed me another 15k for other works not included in the initial invoice. Paid up about 50k already. The job looks "completed" but touch ups were not done. Custom built stool wasnt delivered. My custom built table was also constructed wrongly. I waited for 3 weeks after the renovation, but nothing more was not done. My floor is cement screeded, after just 2 weeks, crack lines which stretches across the floor area appeared. But before that he assured me that the cement uses a special chemical that won't crack. The cement screed is even more expensive than tiling! False ceiling also had cracks. Please advise if this is normal of ID and what can I do? Can I engage another contractor to finish up the works?
