Rooflight glass replacement in Dumfries

Before ordering new glass for a rooflight in Dumfries, we need to know three things: the exact size and thickness of the existing unit, the glass type it needs to match or improve on, and whether the frame is still sound enough to keep. A charged measuring visit, priced before booking, answers all three. If the frame is fine, a new sealed unit is made and fitted on a second visit. If it is not, we price a full replacement instead.

Where our fitters travel

Covering Dumfries means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in DG1, DG2 and DG11, and are happy to quote further out in Hawick and Larkhall. 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 we do on the day

  • Sealed unit ordered to match or improve on the original glass
  • Joints water tested and the glass cleaned inside and out
  • Measuring visit to size the glass and identify its make-up
  • Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.
  • Can the glass come out? — We check whether your rooflight has removable glass or a bonded unit before booking a fitting visit.

How the glass is replaced

The second visit is the quick one. With the new unit made to size, the fitters take the old glass out, check the frame and drainage paths, and set the new glass on packers so it sits square and drains properly. Seals and cappings are renewed where needed, the area is cleared, and you are shown what was done.

Do you need permission in Dumfries?

If you live in Scotland, the key question is whether the job is new or a replacement. A new rooflight needs a building warrant. Swapping an old rooflight for a new one, frame included, doesn't, as long as the new unit meets the standards: the energy figure for new or replacement rooflights in alterations is 1.6 W/m²K. Conservation areas have no householder permitted development rights for roof alterations, and listed buildings need listed building consent.

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 Dumfries

Can I upgrade the glass while it is being replaced?

Usually. Solar-control, self-cleaning, toughened or laminated glass can be specified as long as the frame can take the thickness and weight. We check that on the measuring visit and price the options side by side.

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.

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.

For a repair in Dumfries, start with photos and the postcode; we confirm the visit price before anything is booked.
