We carry out opening vent and actuator repairs in Alloa and across the FK10 area. Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor.

Signs you need opening vent and actuator repairs
- Vent won't open or close
- Leaks from around a closed vent
- Remote or switch unresponsive
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.
About Alloa and the FK10 area
Colder winters mean more frosty mornings, and a roof lantern is often the coldest surface in a warm kitchen — so condensation is as common as genuine leaks. We check which you've got before quoting.
Alloa is around 6 miles from Stirling, and both are within our Stirling and Falkirk coverage.
If you're just outside Alloa, we also cover Stirling (6 miles), Larbert (7 miles), Grangemouth (8 miles).
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.
