In Llanelli, as everywhere, if the room under your lantern overheats in summer or glares, the glass is usually the problem, not the frame. Send photos and we'll tell you what we think has failed.

  • Furniture or flooring fading under the lantern
  • Clear, uncoated glass in an older lantern

Why it happens

Orientation

South- and west-facing lanterns gain the most heat in the afternoon.

No ventilation

A lantern without opening vents traps warm air at ceiling level.

About Llanelli and the SA15 area

Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

Llanelli is around 13 miles from Carmarthen, and both are within our Dyfed coverage.

If you're just outside Llanelli, we also cover Gorseinon (5 miles), Swansea (10 miles), Ammanford (11 miles).

How much should it cost?

Guide price, per glass unit£345–£895 ex VAT£414–£1,074 inc VAT

Typical range: £345–£895 ex VAT, which is £414–£1,074 with VAT, per glass unit. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.

Do you need permission in Wales?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Wales. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010 (as applied in Wales); we confirm in writing which route applies before any replacement. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.

It reduces cleaning on the outer face but still needs rain and occasional rinsing, and the inside still needs cleaning.
