Roof lantern installation in Caerphilly

Guide prices in Caerphilly

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.

Is your address covered?

Covering Caerphilly means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in CF83, CF82 and NP11, and are happy to quote further out in Risca and Pontypridd. 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.

Your roof lanterns or ours

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

On the day, we cover

• Frame assembled on the kerb in the maker's set order
• Roof membrane checked where it meets the lantern frame
• Glass cleaned and packaging cleared from the roof
• Heat and glare — We talk through the glass options before you order a large lantern.
• Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.

Fitting your roof lantern, 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 roof lantern 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.

Do you need permission in Caerphilly?

In Wales, a new rooflight opening generally needs building regulations approval, and a replacement needs either a scheme-registered installer's certificate or a building notice to the council. We are not registered with a scheme, so we use a building notice and show the fee on the quote. Rooflights must meet 2.2 W/m²K and roof windows 1.4 W/m²K. Planning is tighter than in England: rooflights are not permitted development in conservation areas, National Parks, Areas of Outstanding Natural Beauty or World Heritage Sites, so we check your address before quoting.

Details that speed up your quote

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 CF83, and we can price it.
