have engaged an interior designer/contractor to perform renovation of my apartment. He has outsourced the construction of a patio roof to a sub-contractor who has performed shoddy work. The acrylic roof cracked, the wooden structure is not straight, the finishing of the roof is horrible.
I have some questions:
1. How can I check if a contractor is licensed? Is it with SCAL, BCA or other authority?
2. In event that a contractor is not licensed or registered, can I reject their work which has been performed?
3. Am I liable to pay a non-licensed contractor for some work which has no quality control?
4. How can I appeal against a non-licensed contractor?
Greatly appreciate if anyone can provide advice to my concern.
Thanks!
