Description:

The shower silicone is getting moldy and no longer seals well, so I need to remove it and apply new silicone. It is a small area, around the shower base, but I want it to be well sealed so that moisture does not build up again. I would like the old silicone to be removed, the surface to be cleaned well, and new silicone suitable for wet areas to be applied. I need the service to be done carefully so as not to damage the tiles.
