Extractor fan installation in South Glamorgan

We fit bathroom, kitchen and utility fans across South Glamorgan, sized to the room rather than the cheapest box.

Our team is based in Great Barr, Birmingham, and we work throughout South Glamorgan, from Penarth, Llantwit Major, Whitchurch, Rhiwbina and Cardiff. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

Many existing fans were never doing their job: undersized, ducted into the loft space, fitted with a flex duct crushed in the joists, or switched off by occupants because they were noisy. The rate a fan delivers through a real duct run is often far lower than the number on the box, which is why we size to the room and test the result.

Inline fans

A quiet fan in the loft serving one or two ceiling grilles in a shower room or en-suite.

Kitchen extract and cooker hoods

A wall or window fan, or a cooker hood ducted outside rather than recirculating.

Like-for-like replacement

A new fan on the existing duct and wiring, often with an overrun timer or humidity sensor.
