We carry out opening vent and actuator repairs in Billericay and across the CM11 area. Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor.

What you might be seeing
- Vent won't open or close
- Leaks from around a closed vent
- Rain sensor doesn't close the vent
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.
Covering Billericay and nearby
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
From Chelmsford to Billericay is roughly 8 miles — all part of the Essex area we cover.

Guide prices for opening vent and actuator repairs in Billericay
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 England?
In England, 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, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
