A- If your shower screen is leaking there could be several reasons to this, such as silicone bubbles have formed or age and mould has eaten through the silicone causing holes which water can escape from, or frames have come loose due to age and constant use however at times this can be fixed.
B- PECOSA uses Bosch sanitary silicone on all our shower screens , we are able to cut out old silicone and reapply if required prior to offering an alternate solution of purchasing a new screen.
