Where our fitters travel
Jobs across KT22, KT21 and KT23 are part of our normal cover for Leatherhead. 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 Epsom and Cobham are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
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
- New unit set on packers, then beaded, capped or bonded as designed
- Matching the glass make-up — We identify the existing glass so the replacement performs at least as well.
- 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.
Regulations for Leatherhead properties
Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.
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 Leatherhead
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.
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.
Send photos of the problem in Leatherhead and we will price the visit before you book it.
