Smoke vent rooflights (AOVs) in Colchester: what is involved?
Our smoke vent rooflights (AOVs) service in Colchester covers automatic smoke ventilators at the head of stairwells and atria. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
In the East of England, bungalows and chalet bungalows with large flat-roofed extensions are common, and they often suit a long run of rooflights. Typical uses for smoke vent rooflights (AOVs) include blocks of flats and commercial buildings with a smoke strategy.
Colchester sits about 20 km from Sudbury and 21 km from Clacton-on-Sea, and we cover the whole CO1 postcode district and the roads in between.

Common questions
Can you replace an old smoke vent?

Industry guidance recommends regular functional checks and at least annual servicing. Your fire risk assessment sets the regime.
