My house was done by WSL a few years back and i refused to pay the last 5% of the contract price because they are unwilling to rectify all the defects. My solid surface was scratched even before i move in and 3 big tiles in my toilet cracked (its not small scratches or cracks, its big and obvious!). They even have the cheek to tell me that they cant do anything. Like what was mentioned, their sales talk is very impressive but once you sign the contract, everything goes downhill. If you insist to use them, make sure every single item is documented.
