In Eltham, 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.

Is it time for opening vent and actuator repairs?

  • Vent won't open or close
  • Vent stops part-way or makes grinding noises
  • 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 Eltham 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.

Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.

Eltham is around 9 miles from Westminster, and both are within our Greater London coverage.

How much should it cost?

Guide price, per vent£195–£545 ex VAT£234–£654 inc VAT

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.
