Sun tunnel installation in Catford

Plenty of rooflight trouble starts with a tape measure. Units are often sold by the builder's opening, meaning the hole in the roof, rather than the overall external size, and confusing the two leaves you with a frame that does not suit the opening. Before we fit any sun tunnel in Catford, we measure the opening, the upstand or kerb where there is one, and the finished roof level, then compare them with the maker's drawing. If something is out, you hear about it before the fitting day rather than on it. That single check keeps most jobs like this on track.

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?

If you also own a property or a business unit in Lewisham, Brockley or Blackheath, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and SE6, SE13 and SE4 sit comfortably within that pattern.

Buying your own, or letting us supply

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.

What we do on the day

  • Rigid or flexible tube run and joined, with as few bends as possible
  • Dome fixed and sealed on top of the flashing
  • Route through the loft checked for joists, cables and pipes
  • Flat or pitched roof kit — We confirm the roof type and covering before ordering the kit.
  • Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.

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 sun tunnel 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 Catford?

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.

Help us quote accurately

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as SE6.

Common questions in Catford

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

Do you cover Catford?

Yes. Fitters travel to addresses in Catford and the surrounding districts, including SE6. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
