Smoke vent rooflights (AOVs) for Hornchurch: the essentials
We handle smoke vent rooflights (AOVs) across Greater London, including Hornchurch. 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.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
From Hornchurch to Romford, Dagenham and South Ockendon, the same survey-first process applies: measure, specify, fix the price, then fit.

Common questions
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.
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.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.

Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
