  • Rain sensor doesn't close the vent

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.

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

What should you expect to pay in Berkhamsted?

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

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.
