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 Castlereagh and nearby
Fitters travel to the job, so the address is what counts. In Castlereagh that means postcode districts BT6, BT5 and BT7, and the same teams can just as easily take on work in Belfast, about 2 miles away, or Newtownabbey at roughly 6 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.
On the day, we cover
- Old vent removed with the stairwell kept protected below
- Upstand checked, adapted or rebuilt to the vent maker's drawing
- Existing vent, actuator and upstand surveyed with the specialist
- Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
- Fire rules near escape routes — We check the roof around the vent for fire rules that affect it.
A typical installation day
Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a smoke vent rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.
Planning, building control and Castlereagh
In Northern Ireland, smoke vents must be certified products that keep the free area the building's fire strategy requires, with controls connected and commissioned by a smoke-control specialist. The Technical Booklets and building control set the detailed requirement, and we confirm it before quoting.
Help us quote accurately
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 BT6 and we will come back with a quote or a survey date.
Common questions in Castlereagh
Do commercial rooflights need planning permission?
Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
Does a rooflight need building control approval?
In Northern Ireland a new opening alters the roof structure, so expect a building control application; confirm the position with your council, including for replacements. The new rooflight must meet WER Band C or 1.6 W/m²K. We confirm what applies before you commit.
