How we approach extractor fans in Mountain Ash
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.
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.

Rules that apply in Wales
In Wales, ventilation follows the Welsh Approved Document F rather than the English version, with building control checking notifiable work. We design to the Welsh rates and commission mechanical systems so the results can be recorded.
Questions from Mountain Ash
Do you cover Mountain Ash and nearby?
Yes. We cover Mountain Ash and nearby places including Treharris, Rhondda, Aberdare and Merthyr Tydfil. Send your postcode and we will confirm.
How much does it cost to fit an extractor fan?
Replacing a fan on an existing duct usually costs £175 to £295 including VAT. A new fan through an outside wall is typically £345 to £545, and a fan ducted to outside through the loft £445 to £745.
Can an extractor fan vent into the loft?
No. A fan should discharge to outside, because warm, moist air dumped in the loft condenses on the cold roof timbers and causes mould and rot there instead.
What is the price of new extractor fans in Mountain Ash?
