Sun tunnel installation in Swansea

Builders and extension firms in Swansea often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a sun tunnel on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around SA1 and the neighbouring districts are welcome.

Covering SA1 and neighbouring districts

Looking at a property near Swansea but not quite in it? We work across SA1, SA2 and SA5 and outwards to Clydach, Briton Ferry and Gorseinon. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Swansea.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a sun tunnel, 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 opening size and the flashing kit it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

On the day, we cover

  • Route through the loft checked for joists, cables and pipes
  • Roof opening cut and the flashing fitted to tiles, slates or a flat-roof kit
  • Dust cleared from the room below and the loft
  • Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.
  • Condensation in cold lofts — We insulate the tube where it passes through a cold loft.

How a fitting day runs

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 Swansea?

For a Welsh home, start with where the house is. In a conservation area, National Park, AONB or World Heritage Site, a rooflight needs planning permission; outside those, permitted development usually covers one that projects 150 mm or less. Side-facing roof windows within 10.5 m of a boundary must be obscure-glazed and fixed. New openings need building regulations approval, and replacements we fit are notified with a building notice, as we are not registered with a competent person scheme. We confirm all of this for your address.

Before you get in touch

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, SA1 or nearby, confirms travel.

Common questions in Swansea

How long does fitting take?

Fitting a sun tunnel into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

Does a rooflight need building regulations approval?

In Wales a new opening generally needs building regulations approval. A replacement must be self-certified by a scheme-registered installer or covered by a building notice. We are not registered with a scheme, so replacements we fit go through a building notice, and the council's fee is shown on your quote.

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.
