01. What does Glass Door help with? Glass Door runs a shelter service from November until April and an advisory and support (casework) service year-round. Our services are open to all, and we operate on a first-come, first-served basis. You must be over 18 to stay in our shelters, but we can direct you to other more appropriate services if you are under 18. You do not need to bring your ID or any documents to receive help, but they may be useful for our caseworkers to help you.
