Rooflight glass replacement in Royston

Glass replacement is a two-visit job. On the first, the fitter checks the frame, the gaskets and the drainage, and measures the existing unit exactly, including its thickness and glass type. That visit is charged and priced before booking. Once the new sealed unit has been made, the second visit takes the old glass out, cleans and checks the rebate, and beds the new unit in. We do this for rooflight glass units in Royston.

Where our fitters travel

Covering Royston means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in SG8, CB22 and CB2, and are happy to quote further out in Letchworth Garden City and Biggleswade. 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.

On the day, we cover

  • New glazing tapes, gaskets or sealant fitted to suit the frame
  • Frame rebate cleaned and checked for damage, corrosion or failed seals
  • Joints water tested and the glass cleaned inside and out
  • Weight and lifting — We plan how a heavy pane gets onto the roof and into the frame.
  • Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.

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 Royston?

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 Royston

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.

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.

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.
