In Caerphilly, as everywhere, opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos and we'll tell you what we think has failed.
What you might be seeing
- Vent won't open or close
- Rain sensor doesn't close the vent
- Remote or switch unresponsive
Why it happens
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.
About Caerphilly and the CF83 area
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
From Newport, Gwent to Caerphilly is roughly 9 miles — all part of the Gwent area we cover.

Guide prices for opening vent and actuator repairs in Caerphilly
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 Wales?
In Wales, 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 Regulations 2010 (as applied in Wales), so we set out the route in writing first. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
