Smoke vent rooflights (AOVs) for Wood Green: the essentials
Smoke vent rooflights (AOVs) in Wood Green means automatic smoke ventilators at the head of stairwells and atria. We cover the N22 district and the rest of Greater London, with a survey before any price is fixed.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of smoke vent rooflights (AOVs) for blocks of flats and commercial buildings with a smoke strategy.
Wood Green sits about 2 km from Muswell Hill and 2 km from Crouch End, and we cover the whole N22 postcode district and the roads in between.
