Smoke vent rooflights (AOVs) in Chingford: what is involved?
Thinking about smoke vent rooflights (AOVs) in Chingford? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. In Chingford, as anywhere, smoke vent rooflights (AOVs) are the usual choice for blocks of flats and commercial buildings with a smoke strategy.
Neighbouring towns include Woodford Green (3 km) and Edmonton (4 km). We offer a survey date when we reply to your enquiry.
