Smoke vent rooflight installation in Haverfordwest

Glass is heavy, and bigger units get heavy fast. Fitting a smoke vent rooflight in Haverfordwest means planning how it travels from the delivery vehicle to the roof without chipping an edge or straining a back. Smaller units go up by hand with two fitters. Larger ones may need a hoist, a scaffold loading bay or a crane, and we tell you at quote stage if that applies. Once it is up, the fitting follows the maker's sequence: seat, fix, seal, finish. We take on work like this across Dyfed.

Areas around Haverfordwest we cover

Covering Haverfordwest means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in SA61, SA62 and SA73, and are happy to quote further out in Carmarthen and Llanelli. 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

  • Commissioning and sign-off carried out by the specialist before handover
  • Controls, detection and wiring handled by the smoke-control specialist
  • Existing vent, actuator and upstand surveyed with the specialist
  • Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.
  • Free area at the stair head — We check the free area the vent must provide before choosing a replacement.

What happens on the day

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a smoke vent rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning and building rules in Wales

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.

Help us quote accurately

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, SA61 or nearby, confirms travel.

Common questions in Haverfordwest

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.

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.

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.
