In Fulham, 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
- Leaks from around a closed vent
- 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.
About Fulham and the SW6 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
Fulham is around 3 miles from Westminster, and both are within our Greater London coverage.
If you're just outside Fulham, we also cover Chelsea (1 mile), Putney (2 miles), Battersea (2 miles).
Guide prices for opening vent and actuator repairs in Fulham
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?
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.
