Smoke vent rooflights (AOVs) for Sunbury-on-Thames: the essentials
We handle smoke vent rooflights (AOVs) across Surrey, including Sunbury-on-Thames. In short: automatic smoke ventilators at the head of stairwells and atria. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Neighbouring towns include Walton-on-Thames (2 km) and Hampton (4 km). We offer a survey date when we reply to your enquiry.

Questions about smoke vent rooflights (AOVs) in Sunbury-on-Thames
Do smoke vents need a control panel?
Electric AOVs work with a control panel that links them to detectors, the fire alarm and override switches.
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
Who is responsible for maintaining smoke vents?
The responsible person (or duty holder in Scotland, appropriate person in Northern Ireland) for the building must keep fire safety systems maintained. We can arrange servicing and keep records.
Do I need to be at home for the survey in Sunbury-on-Thames?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Sunbury-on-Thames?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
