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.

Like-for-like replacement

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

New fan through an outside wall

Core drilled, sleeved, wired from a fused spur and sealed outside.

Ducted to outside through the loft

Insulated duct to a roof, ridge or soffit outlet so warm moist air does not condense in the loft.

Questions about extractor fan installation in Dumfries and Galloway

Which towns in Dumfries and Galloway do you cover?

All of Dumfries and Galloway, including Stranraer and Dumfries. If your town is not listed, send the postcode and we will confirm.

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.

Should I get a fan with a humidity sensor?

A humidistat fan switches on when the air gets damp and runs until it clears, which suits family bathrooms and rentals where people forget the switch. A continuous-running fan is another good option.

Are prices different in Dumfries and Galloway?

Our guide prices are adjusted by region. In Dumfries and Galloway we use Scotland rates, so like-for-like extractor fan replacement (existing duct and wiring) is typically £170 to £285 inc VAT per fan.
