Wow, this is very unusual for us to see. Vary rarely do we get feedback like this for our installations or after-sales service. We are truly sorry to hear that you aren't completely happy with our work. Poor feedback is something we take seriously in order to improve.
Just to help educate anyone that may be reading this:
We use mildew resistant silicone designed for glass to tile application. We must apply enough of it around the glass in order to hold the glass in place. Silicone on a frameless shower is used to structurally support the glass and also to seal from water leakage.
Silicone does not last forever, especially on the bottom or where water is constantly sitting on it. Some last many years before peeling away, others do not. There are many factors that can have an impact on how long silicone will last. Some examples are, cleaners that are used, how much water sits on the glass/silicone bead, how much use the shower gets, hardness of water in home, type of tile used, whether there is slight movement in the tiles/wall, and whether a sealer was used on the bottom sill or not.
In other words- silicone will not last forever and unfortunately we cannot warranty the silicone application forever. Just like a tub or tiles need silicone re-applied every few years, so does a shower.
We install hundreds of frameless showers every year and its not by accident that we are used by the same customers over and over again. We are not happy to hear this feedback and we wish we could rectify this. Feel free to contact us through email or by phone if you'd like to talk about how we can help.
