Sliding rooflight installation in Gorseinon

Glass is heavy, and bigger units get heavy fast. Fitting a sliding rooflight in Gorseinon 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 Swansea & Neath Port Talbot.

Coverage in and around Gorseinon

Jobs across SA4, SA5 and SA2 are part of our normal cover for Gorseinon. 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 Llanelli and Swansea are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Already bought your unit?

Your unit or ours, the fitting standard is the same. For supply and fit we choose a sliding rooflight to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

On the day, we cover

  • Clear run confirmed for the glass to slide over when open
  • Upstand checked for strength, square and level along its full length
  • Full open and close cycle checked before handover
  • What the glass slides over — We check the area the glass will cover when open before deciding where the unit goes.
  • Power and safety stops — We confirm the power supply and the safety features before fitting day.

From arrival to clean-up

Where a job takes one to two days, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a sliding rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Planning and building rules in Wales

Wales sets energy limits of 2.2 W/m²K for rooflights and 1.4 W/m²K for roof windows, and new rooflight openings generally need building regulations approval. Replacement units are controlled fittings; we are not registered with a competent person scheme, so ours are covered by a building notice to the council. Planning permission is needed for rooflights in conservation areas, National Parks, AONBs and World Heritage Sites. We check which applies and include the fee in your quote.

What to send for a quick quote

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in SA4, and we can price it.

Common questions in Gorseinon

What upstand height and roof pitch does sliding rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

Does a rooflight need building regulations approval?

In Wales a new opening generally needs building regulations approval. A replacement must be self-certified by a scheme-registered installer or covered by a building notice. We are not registered with a scheme, so replacements we fit go through a building notice, and the council's fee is shown on your quote.

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.
