Smoke vent rooflights (AOVs) for Waltham Abbey: the essentials
Smoke vent rooflights (AOVs) in Waltham Abbey means automatic smoke ventilators at the head of stairwells and atria. We cover the EN9 district and the rest of Essex, with a survey before any price is fixed.
Many homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Cheshunt (2 km) and Chingford (6 km). We offer a survey date when we reply to your enquiry.

Common questions
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.
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
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.
Do I need to be at home for the survey in Waltham Abbey?
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 Waltham Abbey?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
