Smoke vent rooflight installation in Bangor

Builders and extension firms in Bangor often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a smoke vent rooflight on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around LL59 and the neighbouring districts are welcome.

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?

Fitters travel to the job, so the address is what counts. In Bangor that means postcode districts LL59, LL57 and LL58, and the same teams can just as easily take on work in Caernarfon, about 9 miles away, or Llandudno at roughly 14 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Included in the work

  • Existing vent, actuator and upstand surveyed with the specialist
  • Upstand checked, adapted or rebuilt to the vent maker's drawing
  • Commissioning and sign-off carried out by the specialist before handover
  • 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.

Fitting your smoke vent rooflight, step by step

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 Bangor?

In Wales, smoke vents must be certified products that keep the free area the building's fire strategy requires, with controls commissioned by a smoke-control specialist. Welsh guidance and building control set the detailed requirement for each building, 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 LL59 and we will come back with a quote or a survey date.

Common questions in Bangor

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.

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.
