Rooflight glass replacement in Greenford

Before ordering new glass for a rooflight in Greenford, 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.

Areas around Greenford we cover

Distance is rarely the deciding factor. A roof in Northolt, 1 mile from Greenford, gets the same survey, the same written quote and the same fitting process as one in UB6, UB1 and UB5. What changes the price is the job itself: size of unit, roof type, access and lifting. Southall, around 2 miles out, is treated the same way.

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
  • Sealed unit ordered to match or improve on the original glass
  • Condition of the frame — We look at the frame closely before committing to new glass.
  • Condensation or a failed seal — We confirm whether the mist is inside the sealed unit or on the room-side surface.

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 Greenford properties

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 Greenford

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.

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.
