Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Dumfries (DG1) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Vent stops part-way or makes grinding noises
- Leaks from around a closed vent
- Rain sensor doesn't close the vent
Why it happens
Actuator failure
Chain actuators wear out or jam, especially if they've been forced.
Power or control faults
Transformers, control units, switches and remotes fail; we check these first.

How much should it cost?
Guide price for opening vent and actuator repairs: £195–£545 ex VAT (£234–£654 inc VAT), per vent. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in Scotland?
In Scotland, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building (Scotland) Regulations 2004, so we set out the route in writing first. Listed buildings in Scotland need listed building consent from the planning authority for alterations, with Historic Environment Scotland guidance; check before changing a lantern on a listed property.
