Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor. Send photos from Dagenham (RM10) and we'll tell you which it is — with the price agreed in writing before any work.

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.

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
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.

What should you expect to pay in Dagenham?
Most opening vent and actuator repairs jobs come in between £195 and £545 ex VAT (£234–£654 including 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.
