Rooflight glass replacement in Swindon

Before ordering new glass for a rooflight in Swindon, 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.

Fitting across Swindon and nearby

If you also own a property or a business unit in Calne, Cirencester or Carterton, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and SN1, SN2 and SN3 sit comfortably within that pattern.

On the day, we cover

  • Frame rebate cleaned and checked for damage, corrosion or failed seals
  • Measuring visit to size the glass and identify its make-up
  • New glazing tapes, gaskets or sealant fitted to suit the frame
  • Can the glass come out? — We check whether your rooflight has removable glass or a bonded unit before booking a fitting visit.
  • Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.

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 England

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the 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 Swindon

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.

Is new glass or a new rooflight better value?

If the frame, gaskets and drainage are sound, new glass is usually the cheaper fix. If the frame is cracked, distorted or leaking at the kerb, a full replacement is better value. After the measuring visit we price both so you can compare.

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.
