Rooflight glass replacement in Mitcham

Condensation between the panes, a crack from a dropped tool, or a unit that has gone cloudy are the usual reasons for rooflight glass replacement in Mitcham. Each needs the existing unit measured and the frame inspected before new glass is ordered, so we start with a charged measuring visit, priced before you book. You then get a written price for the new glass and fitting. Toughened, laminated and solar-control options are matched to what the frame can take.

Coverage in and around Mitcham

Covering Mitcham means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in CR4, SM4 and SW17, and are happy to quote further out in Morden and Tooting. 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.

What the job includes

  • Old glass taken out safely and removed from site
  • New glazing tapes, gaskets or sealant fitted to suit the frame
  • Measuring visit to size the glass and identify its make-up
  • Weight and lifting — We plan how a heavy pane gets onto the roof and into the frame.
  • 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 Mitcham 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

Photos of the problem glass from inside and out, a rough width and length, and whether the rooflight opens or is fixed are enough to price the first visit. Add the postcode and how the roof is reached, and tell us if more than one unit has misted.

Common questions in Mitcham

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.

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 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.
