Rooflight glass replacement in Bognor Regis

A misted or cracked rooflight does not always need a whole new unit. If the frame is sound and the seals around it are dry, we can often measure for a new sealed glass unit and fit it into the existing frame in Bognor Regis. The first visit is to measure and check the frame, which is charged, with the price confirmed before you book. The new glass is then made to size, and a second visit fits it. If the frame itself has failed, we tell you that a replacement rooflight makes more sense.

Fitting across Bognor Regis and nearby

Jobs across PO21, PO22 and PO20 are part of our normal cover for Bognor Regis. 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 Chichester and Littlehampton 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

  • Sealed unit ordered to match or improve on the original glass
  • Joints water tested and the glass cleaned inside and out
  • Frame rebate cleaned and checked for damage, corrosion or failed seals
  • 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

On the fitting visit, the room below is protected first. The beads or cappings come off, the old unit is lifted out with suction lifters, and the rebate is cleaned and checked for damage or blocked drainage. The new sealed unit goes in on fresh packers and gaskets, the cappings are refitted and sealed, and the glass is cleaned. Most glass swaps take half a day once the new glass is made.

Planning, building control and Bognor Regis

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

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 Bognor Regis

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 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.
