We carry out opening vent and actuator repairs in Frome and across the BA11 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
- 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.
Power or control faults
Transformers, control units, switches and remotes fail; we check these first.

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

What should you expect to pay in Frome?
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
