We carry out opening vent and actuator repairs in Mansfield and across the NG18 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 stops part-way or makes grinding noises
- Rain sensor doesn't close the vent
- Remote or switch unresponsive
Why it happens
Power or control faults
Transformers, control units, switches and remotes fail; we check these first.
Seal or hinge problems
A twisted hinge or worn seal stops the vent closing tight.
Roof lanterns in Mansfield
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.

Guide prices for opening vent and actuator repairs in Mansfield
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 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.
