We carry out opening vent and actuator repairs in Andover and across the SP10 area. Opening vents in roof lanterns are usually driven by a chain actuator on a switch, remote or rain sensor.

Is it time for opening vent and actuator repairs?
- Vent won't open or close
- Rain sensor doesn't close the vent
- Remote or switch unresponsive
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.
About Andover and the SP10 area
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.
We cover Andover as part of Hampshire, about 22 miles from Southampton.
Neighbouring places we cover include Winchester (13 miles), Newbury (15 miles), Salisbury (16 miles).
How much should it cost?
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?
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.
