5 Signs It’s Time to Replace Your Bathroom Extractor Fan (Not Just Clean It)
It’s easy to forget about the extractor fan — until your bathroom starts feeling damp, mouldy, or stale.
At EPM, we’re often called out across Exeter, Topsham, and Totnes to look at noisy, underperforming fans. And while cleaning can help, sometimes replacement is the smarter move.
Here are 5 signs your bathroom fan has reached the end of the road — and why it matters more than you think.
1. It Sounds Like a Jet Engine (Or Barely Makes a Sound)
A good fan should make a gentle whirr. If yours is suddenly louder than your shower — or goes totally silent — something’s off.
Loud noise = worn bearings or a motor on the way out.
Silence = failed power supply or motor failure.
2. It’s Not Clearing Steam Anymore
If your mirror stays fogged up for ages or water drips from the ceiling after a short shower, your fan’s performance is fading.
This often means the motor is slowing or the airflow is blocked — but if a clean doesn’t fix it, it’s time to replace.
3. There’s Mould or Mildew Around the Room
A healthy extractor fan helps prevent:
Condensation on windows
Mould on grout and sealant
Musty smells near paintwork
If mould is appearing despite regular cleaning, your fan isn’t pulling enough air — and that’s a problem for both health and the building fabric.
4. It’s Over 10 Years Old
Many older fans weren’t designed for high-humidity modern bathrooms — especially if the window stays closed or the room is internal.
Newer fans are quieter, more powerful, and use far less energy.
They can also be installed with timers or humidity sensors — a game changer in busy homes.
5. It Looks Like It Belongs in a Haunted House
Cracked covers, discoloured plastic, loud clunks at switch-on — if your fan looks like it hasn’t worked properly since the early 2000s, it probably hasn’t.
We see this in plenty of Exeter rentals and East Devon family homes. A tired fan doesn’t just look bad — it’s not protecting your bathroom properly.
What It Might Cost
Basic fan replacement (like-for-like): £120–£180
Upgraded fan with humidistat or timer: £180–£300
New install (including wiring): From £280, depending on access
We’ll confirm the best setup and provide a clear estimate before we start.
Why It Matters
Without proper extraction, bathrooms:
Develop damp and mould
Damage paint, tiles, and ceilings
Can trigger respiratory issues, especially in children
A new fan is one of the simplest upgrades you can make — and one of the most overlooked.
Final Word from EPM
