Installing Glass Staircase Balustrades and Railings? Installing glass balustrades and railings is actually very easy. The first thing that the contractor will need to do is to remove the existing balustrades, posts and handrails. Installers then need to remove the existing steps and remove the old treads. This is the number that you will find at the end of every stair that you are building. It's not necessary, so the contractor may decide to just remove it. After removing all the old parts, the contractor will start the process of installing the new glass balustrade and railing. They will be able to fix the balustrade to the railing using stainless steel brackets. You won't need to use any kind of screws to secure the glass railing to the posts; it can be fixed with a simple screw. When the work is done, the contractor will make sure that the new glass balustrade and railing look good.
