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.
Is your address covered?
Covering Wrexham means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in LL13, LL11 and LL12, and are happy to quote further out in Brymbo and Rhosllannerchrugog. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
What the job includes
- Existing vent, actuator and upstand surveyed with the specialist
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Certified vent and actuator matched to the opening and controls
- Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.
- 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, building control and Wrexham
Replacing a smoke vent in Wales means matching the certified performance and free area of the system, with the controls connected and commissioned by a specialist. We confirm with you whether building control needs to be involved.
What to send for a quick quote
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, LL13 or nearby, confirms travel.
Common questions in Wrexham
What upstand height and roof pitch does smoke vent rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
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.
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.
