Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Kirkcaldy (KY1) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Vent won't open or close
- 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.
Covering Kirkcaldy and nearby
Snow and ice sitting at the eaves can block a lantern's drainage and push water back under the glass as it melts. If your lantern leaks after a thaw rather than after rain, tell us — it points to the eaves and kerb.
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.
From Dunfermline to Kirkcaldy is roughly 12 miles — all part of the Fife area we cover.

How much should it cost?
Typical range: £195–£545 ex VAT, which is £234–£654 with 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.
