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 Antrim and nearby
Jobs across BT41, BT29 and BT39 are part of our normal cover for Antrim. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Ballymena and Newtownabbey are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Included in the work
- Old vent removed with the stairwell kept protected below
- New vent fitted, sealed and weathered into the roof
- Certified vent and actuator matched to the opening and controls
- Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.
- Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.
From arrival to clean-up
Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a smoke vent rooflight: one to two days per vent, weather permitting.
Planning and building rules in Northern Ireland
Replacing a smoke vent in Northern Ireland means keeping the certified performance and free area of the system, with a specialist commissioning the controls. We confirm with you whether building control needs to be involved.
Before you get in touch
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 BT41 and we will come back with a quote or a survey date.
Common questions in Antrim
How does payment work?
Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
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.
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.
