I can give 1 example that I still remember. I want to overlay vinyl for my bedrooms and living room. No one ever explained to me that the skirtings should be hacked, if not it will be ugly. No one told me that my doors need to be trimmed. No one told me that overlaying might affect the main gate and sometimes can’t be helped but to change it if want it to be nice. Layman like me, wouldn’t know about all these. He made a good point that all these can be a form of ‘hidden’ charges if all these not communicated. The whole project was completed smoothly. A bit hiccups here and there but I feel that it’s normal. Easy to communicate with him and he reply to chats almost instantly, every time!
