Smoke vent rooflights (AOVs) for Dolgellau: the essentials
We handle smoke vent rooflights (AOVs) across Gwynedd, including Dolgellau. 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.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Smoke vent rooflights (AOVs) suit communal stairwells, corridors and atria.
We work across Gwynedd, including Dolgellau, and in neighbouring towns such as Machynlleth and Porthmadog. Access, parking and how the glass reaches the roof are all checked at the survey.

What to check first

Rules and responsibilities in Dolgellau
Smoke vents are life-safety equipment: in Wales the responsible person must keep them maintained under the Regulatory Reform (Fire Safety) Order 2005 (as it applies in Wales). We supply manufacturer-certified units and arrange installation, commissioning and servicing through specialist smoke-control engineers.
For non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fire classification of rooflight materials near boundaries is checked at specification.

Common questions
Do you design the smoke strategy?
No — the strategy comes from the building's fire engineer or designer. We supply, install, commission and service to it.
Can a smoke vent be used for normal ventilation?
Many dual-purpose units also open for daily ventilation, closing automatically in rain.
Can you replace an old smoke vent?
Yes, with an equivalent certified unit that matches the original design area and performance, so the fire strategy is not compromised.
Do I need to be at home for the survey in Dolgellau?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Dolgellau?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
