At EPM, we understand that one of the most frustrating issues you can face in a bathroom renovation is the growth of mould and mildew. These unwelcome guests thrive in humid, damp environments, and bathrooms—where moisture is always present—are their perfect breeding grounds.
Not only can they be unsightly, but they can also pose health risks, damage your property, and even ruin your beautiful bathroom. So, how do you protect your space and keep your bathroom fresh and healthy for the long term? In this guide, we’ll share essential tips on preventing mould and mildew, ensuring your bathroom renovation lasts and stays pristine.
1. Proper Ventilation: Your First Line of Defence
The most important step in preventing mould and mildew is making sure your bathroom is properly ventilated. Without proper airflow, moisture builds up, creating the perfect environment for mould to grow.
How to Do It:
- Install an extractor fan: A good extractor fan will remove excess moisture from the air, especially during and after showers or baths. Ensure it’s powerful enough for the size of your bathroom. Look for fans with a timer or humidity sensor for convenience.
- Open windows when possible: If you have windows in your bathroom, open them to let fresh air in. Even a small amount of airflow can help reduce moisture.
- Leave the door ajar: After a shower or bath, leave the door open to help the room dry out faster.
🔹 Pro Tip: Ensure your extractor fan is vented to the outside, not just into the attic or loft space, to avoid recirculating damp air back into the room.
2. Moisture-Resistant Materials: Build Smart
Using the right materials is essential in fighting mould and mildew. Not all bathroom materials are created equal, and some are more resistant to moisture than others.
How to Do It:
- Choose mould-resistant paints: Look for bathroom-specific paints that are mould and mildew-resistant. These are designed to withstand the damp conditions in your bathroom.
- Use moisture-resistant tiles or shower panels: Porcelain and ceramic tiles are ideal for bathroom walls and floors, as they’re non-porous and easy to clean. Shower panels are another great option, especially if you want a seamless, low-maintenance finish.
- Consider water-resistant grout: Traditional grout can absorb moisture and become a breeding ground for mould. Using a grout that resists moisture will help keep your tiles in top condition.
- Opt for a vinyl or luxury vinyl floor: Vinyl floors are water-resistant, durable, and easy to clean—making them a great choice for high-moisture areas.
- Ensure your fitter uses moisture-resistant plasterboard: When renovating, it’s crucial to ensure your bathroom fitter uses moisture-resistant plasterboard, particularly in areas prone to damp, like behind showers and baths. This will protect the structure of your bathroom and prevent mould from developing within the walls.
3. Keep It Dry: Regular Maintenance and Cleaning
One of the simplest but most effective ways to prevent mould and mildew is to keep surfaces dry. Regular maintenance is key to keeping moisture at bay and avoiding long-term damage.
How to Do It:
- Wipe down surfaces after use: After showering or bathing, take a few minutes to wipe down the walls, mirrors, and shower doors with a dry towel. This will prevent excess water from sitting on surfaces for too long.
- Clean your extractor fan: Dust can build up in your extractor fan, reducing its effectiveness. Regularly clean it to ensure it’s working properly.
- Clean your grout: Grout can attract dirt and moisture, so it’s important to clean it regularly. Use a mild cleaning solution, and avoid harsh chemicals that can damage the surface.
- Mop up standing water: After each shower or bath, check for any standing water on the floor and mop it up. Puddles of water are a direct invitation for mould and mildew to grow.
🔹 Pro Tip: Use a squeegee to remove excess water from your shower walls after each use to prevent water from sitting on the surface.
4. Improve Heating: Warm and Dry Is the Way to Go
It might sound counterintuitive, but keeping your bathroom warm and dry is actually one of the best ways to prevent mould and mildew. Cold, damp spaces are where these issues thrive.
How to Do It:
- Install underfloor heating: Underfloor heating can help dry out the bathroom and maintain a consistent temperature, which prevents condensation.
- Use a heated towel rail: Not only do heated towel rails keep your towels dry and warm, but they also help dry out the bathroom after a shower or bath. Plus, they add a touch of luxury to the space.
Invest in a bathroom radiator: If underfloor heating isn’t an option, a good radiator will help circulate warm air and reduce moisture in the air.
5. Prevent Leaks: Check for Water Damage Regularly
Water leaks are one of the biggest contributors to mould and mildew problems. Even a small leak can cause damage over time, leading to damp conditions that encourage growth.
How to Do It:
- Check plumbing regularly: Periodically check for any leaks in your pipes, showerheads, and taps. Even small leaks can lead to bigger problems down the road.
- Seal gaps and cracks: Ensure that all areas around your bath, shower, sink, and toilet are properly sealed. Silicone sealant can help protect against water damage, but it will need to be replaced periodically to maintain its effectiveness.
- Fix any leaks immediately: If you notice a leak or pooling water, address it right away to prevent it from turning into a bigger issue.
6. Proper Drainage: Ensure Water Can Leave the Room
Proper drainage is essential for keeping your bathroom dry. If water can’t leave the room quickly enough, it will sit on the surfaces and increase the chances of mould and mildew growth.
How to Do It:
- Check your drains regularly: Ensure that the drainage system in your bathroom is clear and working properly. If drains get blocked, water can pool in areas where it shouldn’t be.
- Ensure good slope in the shower: When installing or renovating your shower, make sure there’s a slight slope towards the drain to help water flow easily out of the space.
7. Invest in a Professional Bathroom Renovation
Sometimes, preventing mould and mildew comes down to the quality of your initial renovation. At EPM, we understand that a well-installed bathroom with the right materials can go a long way in preventing water damage and mould.
How to Do It:
- Work with professionals: A professional bathroom renovation ensures that the job is done correctly from the start. From waterproofing to installing moisture-resistant materials, experts will ensure your bathroom is built to last.
