Wardrobe sliding doors is not a big problem I think that can't be handled. Maybe check by google or YouTube videos? When it comes something to do in our house we first try with my husband to do by ourselves. We do many things together, and I try to support him. When we have a new case or need some opinions and guidance we use https://guides4homeowners.co.uk and know how to fix something in our shower, or even outside the house many topics are available, very interesting and helpful! There are hundreds of articles and I think your case is available there also!
