Smoke vent rooflights (AOVs) in Machynlleth: what is involved?
Our smoke vent rooflights (AOVs) service in Machynlleth 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.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Think of smoke vent rooflights (AOVs) for communal stairwells, corridors and atria.
Machynlleth sits about 17 km from Dolgellau and 25 km from Aberystwyth, and we cover the whole SY20 postcode district and the roads in between.
