Loft conversion roof windows in Swansea

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for loft conversion roof windows in Swansea, internal finishing is listed so you can see whether it is included or left for your decorator. That way a loft roof window looks right from the room below as well as from outside. We cover Swansea and properties throughout Swansea & Neath Port Talbot.

Guide ranges for supply & fit. 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?

Jobs across SA1, SA2 and SA5 are part of our normal cover for Swansea. 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 Clydach and Briton Ferry are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What we check on a supplied unit

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

Included in the work

  • Tiles or slates cut and refitted, with the roof left weathertight
  • Underlay dressed and taped around every frame
  • Insulation collars fitted so the room's insulation meets each frame
  • Approved loft drawings — We work to the window positions on your approved loft drawings or agree changes with your builder first.
  • Fitting stage and weather — We plan when the windows go in around the rest of the conversion.

From arrival to clean-up

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A loft roof window goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one to two days.

Planning and building rules in Wales

In Wales, a new rooflight opening generally needs building regulations approval, and a replacement needs either a scheme-registered installer's certificate or a building notice to the council. We are not registered with a scheme, so we use a building notice and show the fee on the quote. Rooflights must meet 2.2 W/m²K and roof windows 1.4 W/m²K. Planning is tighter than in England: rooflights are not permitted development in conservation areas, National Parks, Areas of Outstanding Natural Beauty or World Heritage Sites, so we check your address before quoting.

Details that speed up your 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 SA1, and we can price it.

Common questions in Swansea

What if my roof opening is the wrong size for the loft roof window?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
