Fitting across Glasgow and nearby
Jobs across G2, G4 and G1 are part of our normal cover for Glasgow. 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 Rutherglen and Bishopbriggs are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Included in the work
- Old glass taken out safely and removed from site
- Frame rebate cleaned and checked for damage, corrosion or failed seals
- New glazing tapes, gaskets or sealant fitted to suit the frame
- Condensation or a failed seal — We confirm whether the mist is inside the sealed unit or on the room-side surface.
- Weight and lifting — We plan how a heavy pane gets onto the roof and into the frame.
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.
Planning and building rules in Scotland
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 Glasgow
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.
