Rooflight glass replacement in Mountsorrel

Before ordering new glass for a rooflight in Mountsorrel, 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

Mountsorrel and the districts around it, LE4, LE12 and LE7, all sit inside our working area. So does the ground between Mountsorrel and Loughborough (4 miles), and on towards Leicester (5 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

On the day, we cover

  • Joints water tested and the glass cleaned inside and out
  • New unit set on packers, then beaded, capped or bonded as designed
  • 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.
  • Condition of the frame — We look at the frame closely before committing to new glass.

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, building control and Mountsorrel

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

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 Mountsorrel

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.

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.

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