What do smoke vent rooflights (AOVs) in Orpington involve?
We handle smoke vent rooflights (AOVs) across Greater London, including Orpington. 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.
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. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
