Mould forms when moisture, warmth, and organic material combine to create a hospitable environment for fungal growth. Common causes of mould on double glazing include:
- Condensation: Double-glazing windows can trap heat inside the home, leading to condensation on the colder surfaces of the glass. If not wiped away, this moisture provides the perfect breeding ground for mould.
- Poor Ventilation: Rooms with inadequate airflow, such as bathrooms and kitchens, are more prone to mould formation due to higher humidity levels.
- Leaky Windows: Damaged seals or frames can allow water to seep in, creating damp areas where mould can thrive.
Understanding the cause of mould is key to addressing it effectively and preventing future issues.
How to Remove Mould from Double Glazing
Removing mould requires care to ensure it doesn’t spread further or cause health issues during the cleaning process. Follow these steps:
- Safety First:
- Wear protective gloves, a mask, and goggles to avoid contact with mould spores.
- Open windows or use a fan for ventilation while cleaning.
- Prepare a Cleaning Solution:
- Mix one part white vinegar with two parts water in a spray bottle. Alternatively, use a mould-specific cleaner available at most hardware stores.
- Avoid bleach for regular cleaning as it can discolour frames and weaken seals.
- Apply the Solution:
- Spray the cleaning solution onto the mouldy area, focusing on the affected glass, seals, and frame edges.
- Let it sit for 10-15 minutes to break down the mould.
- Scrub Gently:
- Use a soft brush or non-abrasive cloth to scrub the area, removing all visible mould.
- Be careful not to damage seals or frames while cleaning.
- Wipe Clean and Dry:
- Wipe away any remaining residue with a damp cloth.
- Dry the area thoroughly to remove all moisture.
Preventing Mould on Double Glazing
Once the mould is removed, take steps to prevent it from coming back:
- Improve Ventilation:
- Use extractor fans in kitchens and bathrooms.
- Open windows regularly to allow fresh air to circulate.
- Consider installing trickle vents in your double-glazing frames.
- Reduce Condensation:
- Wipe down windows daily to remove excess moisture.
- Use a dehumidifier to control humidity levels in your home.
- Insulate your windows properly to minimise temperature differences that cause condensation.
- Maintain Windows:
- Check seals and frames for damage or leaks and repair them promptly.
- Clean windows regularly to remove dirt and grime, which can encourage mould growth.
- Add Moisture Absorbers:
- Place moisture-absorbing products near windows to help reduce dampness. Silica gel or reusable dehumidifier sachets are effective options.
When to Seek Professional Help
If mould persists despite your efforts or if it has spread extensively, it’s best to call in professionals. They can assess the underlying causes, such as structural issues or compromised window seals, and provide expert solutions.
