Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Dunfermline (KY12) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing

Common causes we find
Actuator failure
Chain actuators wear out or jam, especially if they've been forced.
Seal or hinge problems
A twisted hinge or worn seal stops the vent closing tight.

Freeze-thaw cycles open up tired sealant and gaskets faster than mild weather does. A spring check after a hard winter catches most problems before they leak.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
Neighbouring places we cover include Bo'ness (7 miles), Linlithgow (9 miles), Kinross (9 miles).
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?
Most lantern repairs in Scotland need no approval at all. Where a job turns into a replacement, the Building (Scotland) Regulations 2004 apply and we confirm how the work will be signed off before we start. 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.
