My builder is quite bad at communication. The site supervisor will not provide their mobile number and I have to email queries to them. Quite often, this doesn't get responded to, so I have to email again. What's the best way to try to get the builder to communicate? They said they prefer to communicate via email (but it seems like it's so that they can avoid being put on the spot). The building work is okay so far (only minor issues), but it's super hard when they don't communicate properly! They are a small Perth based builder. Hopefully someone has had some similar experiences that turned good!
