Questions from Treharris
How do I get a price for a ventilation repair in Treharris?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
Is it worth repairing an old extractor fan?
Usually not for a basic bathroom fan, because a new fan costs little more than the repair. MVHR, PIV and commercial fans are often worth repairing.
Why is my extractor fan humming but not spinning?
A humming fan that does not spin often has a failed capacitor, seized bearing or obstruction. It should be switched off until repaired.
