We had a leak from our shower enclosure tray in the in suite bedroom into our guest bathroom located in the ground floor. We called back the builder who fitted the bathroom and a few others who advised that replacing the silicon would stop this. this was immediately done . After nearly a year that en suite bathroom hasn?t been used but it still smell. We want some reliable and honest and they guarantee their job and I said this because I ?heard? many things for some ?professional? that came to see and the job they suggested goes from ?80 to ?3000.
