Rooflight glass replacement in Portslade

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 Portslade. 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.

Covering BN41 and neighbouring districts

Jobs across BN41, BN3 and BN1 are part of our normal cover for Portslade. 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 Hove and Shoreham-by-Sea are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What we do on the day

  • Old glass taken out safely and removed from site
  • New glazing tapes, gaskets or sealant fitted to suit the frame
  • 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.
  • Condition of the frame — We look at the frame closely before committing to new glass.

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 Portslade

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 Portslade

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.
