Guide ranges for supply & fit; controls and commissioning by a smoke-control specialist. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Fitting across Farnborough and nearby
If you also own a property or a business unit in Camberley, Aldershot or Fleet, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and GU14, GU17 and GU11 sit comfortably within that pattern.
Included in the work
- Controls, detection and wiring handled by the smoke-control specialist
- Existing vent, actuator and upstand surveyed with the specialist
- Old vent removed with the stairwell kept protected below
- Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
- Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.
How a fitting day runs
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a smoke vent rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one to two days per vent.
Planning and building rules in England
In England, smoke vents for common stairs must be certified to BS EN 12101-2, provide the free area the fire strategy requires (Approved Document B calls for at least 1 m² at the top of a common stair), and have backup power. Smoke vents have their own energy limit, commonly 3.5 W/m²K. Controls and commissioning are handled by a smoke-control specialist, and building control is involved where the system changes.
Getting a price from photos
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around GU14 and we will come back with a quote or a survey date.
Common questions in Farnborough
Do you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
Will my new smoke vent rooflight leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
Does commercial rooflight work need building control?
Usually. New openings, structural changes and smoke vents go through building control, and on buildings covered by fire safety law that means a full plans application rather than a building notice. We are not registered with a competent person scheme, so replacements we fit are notified to building control. We confirm the route and show any fee on the quote.
