Frameless rooflight installation in New Malden

Frameless rooflight installation in New Malden comes down to what happens around the glass. A good unit sat on a poor upstand, or with the membrane or flashing cut short at the corners, will still let water in. We fit each frameless rooflight to the maker's instructions for fixings, packers and sealant, for homes and businesses across New Malden and the rest of Greater London. That covers supply and fit, fit-only for a unit you already own, and swapping out a tired one. Every job starts with a written quote, so the price and scope are clear before anyone climbs a ladder.

Guide ranges for supply & fit. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.

Where our fitters travel

Jobs across KT3, KT5 and KT1 are part of our normal cover for New Malden. 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 Worcester Park and Surbiton 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 check on a supplied unit

If you have bought a frameless rooflight yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the upstand height above the finished roof. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

What we do on the day

  • Roof covering turned up and finished under the glass overhang
  • Upstand built to the maker's drawing within its stated tolerance
  • Glass bedded on the specified tape or sealant and fixed through the concealed frame
  • Tolerance on the upstand — We build frameless kerbs to the maker's tolerance rather than to normal carpentry accuracy.
  • How the reveal will look — We agree the finish at the glass edge before building anything.

What happens on the day

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a frameless rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Planning and building rules in England

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.

Help us quote accurately

A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, KT3 or a neighbouring district.

Common questions in New Malden

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.

Send a few photos and your KT3 postcode, and we will put together a written quote for the job.
