Yes. We cover Darwen and nearby places including Blackburn, Haslingden, Accrington and Great Harwood. Send your postcode and we will confirm.
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.
