Why bathrooms get mould first
Bathrooms are small, warm and get wet every day. Steam hits the coldest surfaces first, which is usually the ceiling, the external wall and the window. If the extractor fan is weak, broken, never left running, or ducted badly, the moisture sits on those surfaces and mould follows. Most bathroom mould we see comes down to ventilation.
What we do in your bathroom
- Fungicidal clean and treatment of the ceiling, walls and window reveal
- Cut out and replace mouldy silicone around the bath, shower tray and basin with mould resistant sealant
- Clean and treat grout lines, or regrout where the grout is too far gone
- Stain block and anti mould bathroom paint on the ceiling and affected walls
- Check the extractor fan: is it pulling air, is it ducted outside, does it have an overrun timer
Fixing the ventilation
If the fan is the problem, we can replace it with a quiet, continuously running or humidity controlled fan, which is the single best thing you can do for a mouldy bathroom. Fan supply and fitting is quoted separately so you can see exactly what you pay for. See extractor fans and PIV units.
Simple habits that help
- Leave the fan running for 15 to 20 minutes after a shower
- Keep the door closed while showering so steam does not travel through the home
- Squeegee the tiles and screen after showering
- Keep the bathroom heated to a steady temperature in winter
