Silicone Mould Keeps Coming Back
Black mould along the bath or shower seal is common. Cleaning helps short-term, but a proper reseal with good ventilation usually stops it coming back. We reseal baths and showers across Leeds.
Fix & Patch Leeds is roofing-first for leak source control, with secondary internal repairs for water damage to walls, floors and ceilings where needed.
Step-by-step
Clean with a mould remover – follow the instructions and ventilate well.
Improve ventilation – extractor fan, open window, wipe surfaces dry after use.
If mould returns quickly, the silicone may be porous or failing – reseal it.
Strip old silicone fully, clean and dry the area, then apply new mould-resistant sealant.
Common mistakes
- ⚠ Bleach-based cleaners can damage some surfaces – test first.
- ⚠ Don’t seal over old silicone – it won’t adhere properly.
