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.
Areas around Aberdare we cover
Fitters travel to the job, so the address is what counts. In Aberdare that means postcode districts CF44, CF48 and CF43, and the same teams can just as easily take on work in Rhondda, about 4 miles away, or Merthyr Tydfil at roughly 4 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.
What we do on the day
- Commissioning and sign-off carried out by the specialist before handover
- Old vent removed with the stairwell kept protected below
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.
- Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
What happens on the day
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.
Do you need permission in Aberdare?
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.
Before you get in touch
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, CF44 or nearby, confirms travel.
Common questions in Aberdare
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.
What if my roof opening is the wrong size for the smoke vent rooflight?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
How long does fitting take?
Fitting a smoke vent rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
