Rooflight glass replacement in Porthcawl

Condensation between the panes, a crack from a dropped tool, or a unit that has gone cloudy are the usual reasons for rooflight glass replacement in Porthcawl. Each needs the existing unit measured and the frame inspected before new glass is ordered, so we start with a charged measuring visit, priced before you book. You then get a written price for the new glass and fitting. Toughened, laminated and solar-control options are matched to what the frame can take.

Covering CF36 and neighbouring districts

Looking at a property near Porthcawl but not quite in it? We work across CF36, CF33 and CF31 and outwards to Bridgend, Maesteg and Briton Ferry. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Porthcawl.

What we do on the day

  • New unit set on packers, then beaded, capped or bonded as designed
  • New glazing tapes, gaskets or sealant fitted to suit the frame
  • Sealed unit ordered to match or improve on the original glass
  • Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.
  • Weight and lifting — We plan how a heavy pane gets onto the roof and into the frame.

How the glass is replaced

On the fitting visit, the room below is protected first. The beads or cappings come off, the old unit is lifted out with suction lifters, and the rebate is cleaned and checked for damage or blocked drainage. The new sealed unit goes in on fresh packers and gaskets, the cappings are refitted and sealed, and the glass is cleaned. Most glass swaps take half a day once the new glass is made.

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 us

To price the measuring visit, send a photo of the rooflight from inside showing the misting or crack, one from outside if you can reach a safe viewpoint, and the rough size of the glass. If you know the make or have the original paperwork, include that too, along with the postcode.

Common questions in Porthcawl

Can you replace just the glass in my rooflight?

Often, yes. If the frame, gaskets and drainage are sound, a new sealed unit can go into the existing frame. If the frame has failed, is distorted or leaks around the edge, replacing the whole rooflight is usually the better answer, and we tell you that.

How long does new rooflight glass take?

The new sealed unit is made to the measured size, so there is a gap between the measuring visit and the fitting visit while it is produced. We give you the expected timing when we price the glass, and book the fitting once it has arrived.

Is the measuring visit charged?

Yes. The first visit measures the existing glass and checks the frame, and it is charged. We confirm that price before you book. The fitting of the new glass is then priced in writing, so you see the full cost before anything is ordered.
