Mould in the bathroom can be a frustrating problem for many homeowners. It’s not only unsightly but can also cause health issues like respiratory problems and allergies. When I visit homes, I notice mould is often a recurring issue for many. The good news is, that with the right prevention methods, you can keep mould at bay.
In this article, I’ll walk you through seven effective ways to prevent bathroom mould, based on my personal experience and expert advice. These tips will help you maintain a mould-free bathroom, saving you time and money in the long run.
1. Improve Ventilation
One of the leading causes of mould in bathrooms is excess moisture, and poor ventilation is a big contributor to this. Bathrooms without adequate airflow tend to trap moisture, making them a perfect breeding ground for mould. Installing a good-quality exhaust fan is crucial.
In my personal experience, I always recommend leaving the exhaust fan on for about 20 minutes after a shower or bath. If possible, open a window to let the fresh air circulate, which will help reduce moisture quickly.
- Tip: Ensure your exhaust fan is powerful enough for your bathroom size. A fan should move at least 1 cubic foot of air per minute (CFM) per square foot of bathroom space. According to the U.S. Environmental Protection Agency, proper ventilation is essential for controlling indoor air quality and preventing moisture build-up.
2. Wipe Down Wet Surfaces
Water left standing on surfaces like tiles, mirrors, and shower doors is another major cause of mould. When I work with clients, I recommend keeping a squeegee handy. After each shower, a quick wipe down of these wet surfaces can go a long way in preventing mould from forming.
- Focus Areas:
- Shower walls
- Bathtub edges
- Sinks and countertops
It may feel like an extra step, but trust me, this simple habit makes a big difference.
3. Fix Leaks Immediately
Leaking faucets, showerheads, or pipes can create a constant source of moisture that leads to mould growth. During my plumbing visits, I often find leaks that have gone unnoticed for weeks or even months. By the time the mould is visible, the problem has often spread and can become costly to fix.
If you suspect any leaks, it’s essential to address them as soon as possible. Even a small drip can lead to major mould growth over time.
- Warning Sign: Check for any soft spots on walls or ceilings, as this can indicate hidden leaks. If you’re unsure, consider contacting us at Watermark Plumbing for a professional inspection.
4. Use Mould-Resistant Paint
Another tip I frequently share with homeowners is to invest in mould-resistant paint. This type of paint contains antimicrobial agents that prevent mould and mildew from forming on walls and ceilings.
When painting or renovating your bathroom, be sure to choose a mould-resistant formula, especially for areas exposed to moisture. It’s a simple upgrade that can make a big difference.
- Pro Tip: Look for paints that are specifically labeled as “mould and mildew resistant.” These work well in high-humidity areas like bathrooms and are a cost-effective way to prevent mould in the long term.
5. Regular Cleaning with Mould-Preventive Products
Regular cleaning is another key to keeping mould under control. However, not all cleaning products are created equal. When it comes to mould, I suggest using cleaners that are specifically designed to prevent mould and mildew.
White vinegar is a natural and effective cleaner that I personally recommend. It’s eco-friendly and can kill about 82% of mould species. You can mix it with water and use it to wipe down surfaces regularly. Alternatively, you can use commercial bathroom cleaners that contain anti-mould agents.
- Routine: Clean your bathroom at least once a week, focusing on areas that are frequently exposed to water like the shower and sink. This will prevent mould spores from settling and growing.
6. Ensure Proper Grout and Sealants
Grout and sealant in your bathroom tiles and around the tub or shower play a big role in keeping moisture out. Over time, these can wear down, creating tiny cracks where water can seep in. This trapped moisture becomes a perfect environment for mould.
During bathroom inspections, I often find that cracked grout or worn-out caulking is a common cause of mould build-up. Re-sealing or re-grouting these areas can help.
- DIY Tip: You can reapply sealant every year to keep it in good condition. For large areas, or if you’re unsure, you can always reach out to a professional plumber for assistance.
7. Install a Dehumidifier
If your bathroom is in an area of your home that doesn’t have great natural airflow—such as in a basement or without windows—you might want to consider a dehumidifier. These devices pull moisture from the air, keeping the bathroom dry.
In cases where ventilation improvements alone are not enough, a dehumidifier can provide the extra help you need. When I encounter very damp bathrooms, I recommend small portable units that are easy to place in the room and maintain.
- Humidity Levels: Try to keep the bathroom’s humidity level below 50%. This will significantly reduce the likelihood of mould growth.
