Dome rooflight replacement in Barnet

What the job costs in Barnet

Guide ranges for supply & fit, per dome; building control notice fee extra on homes in England and Wales. 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.

Covering EN5 and neighbouring districts

Fitters travel to the job, so the address is what counts. In Barnet that means postcode districts EN5, EN4 and N20, and the same teams can just as easily take on work in East Barnet, about 2 miles away, or Friern Barnet at roughly 3 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Your dome rooflights or ours

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a dome rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

Included in the work

• Old dome unscrewed, lifted off and taken away
• Kerb top cleaned of old sealant, fixings and loose felt
• Adaptor or packing fitted where the old kerb needs it
• Upgrading to glass — We check whether the kerb suits a glass unit before recommending one.
• Multi-skin domes and energy — We fit multi-skin domes rather than single-skin ones as replacements.

Fitting your dome rooflight, step by step

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 dome 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.

Regulations for Barnet properties

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

Before you get in touch

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in EN5, and we can price it.
