Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Godalming (GU7) and we'll tell you which it is — with the price agreed in writing before any work.

What you might be seeing
- Vent won't open or close
- Vent stops part-way or makes grinding noises
- Remote or switch unresponsive
What usually causes it?
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.
Covering Godalming 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.
Godalming is around 4 miles from Guildford, and both are within our Surrey coverage.

What should you expect to pay in Godalming?
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.
