Few things are more frustrating than stepping into a bathroom only to notice mould creeping along the tiles, ceiling, or grout lines. Beyond being unsightly, mould can trigger allergies, damage surfaces, and signal hidden moisture problems in your home. At HydroWorks Plumbing, we’ve seen firsthand how quickly mould can spread in damp environments like bathrooms—and we know prevention is always easier than remediation.
Here are five powerful ways to prevent bathroom mould from taking over your space:
1. Improve Ventilation
Bathrooms trap a lot of moisture from showers and baths, making them the perfect breeding ground for mould. To reduce humidity:
Install or upgrade an exhaust fan and run it during and after showers.
Keep windows slightly open to promote airflow.
Leave the bathroom door ajar when possible.
Pro tip: Run your fan for at least 20 minutes after showering to properly clear out excess steam.
2. Fix Leaks Immediately
Even the smallest plumbing leak can cause hidden mould growth behind walls or under floors. Common culprits include:
Dripping faucets
Leaky showerheads
Loose toilet seals
Hidden pipe cracks
At HydroWorks Plumbing, we often find mould in bathrooms directly tied to slow leaks. Quick repairs can save you from costly damage later.
3. Keep Surfaces Dry
Mould thrives on damp surfaces. Adopt these simple habits:
Wipe down shower walls, mirrors, and counters after use.
Use a squeegee to remove water from tiles and glass doors.
Hang towels to dry instead of leaving them in piles.
