I need someone to repair the protective metal edge trims (stair nosing) on my indoor staircase. Some of the trims have started to separate and split open, leaving visible gaps between the metal pieces. I would appreciate it if someone could securely reattach or repair the trims so they sit flush and are safe to walk on. Ideally, I would prefer to repair the existing trims rather than replace them, unless replacement is necessary. Thank you!
