No appointment made .. Just randomly walk in and was greeted by the staff’s there and welcomed to sit inside while they recommend me to Fred .. We would like to thank Freddi Tan our ID for giving us a lot of advice and suggestions on our full renovation and the price quotation on additional tiles for my stairs, hacking and building another store room with door/frame made fair and possible .. Fred is a patient guy and will find time for us and at our convenience and after each installation he will keep us updated in groupchat .. overall we are very pleased we made the right choice in trusting CASA ID .. thank you guys so much 👍🏻
