  • A crack running from an edge (often thermal stress)

Hail, falling branches or dropped tools.

Thermal stress

Uneven heating across a pane, edge damage or partial shading can crack glass from the edge.

Covering Pontypridd and nearby

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

Pontypridd is around 12 miles from Bridgend, and both are within our Mid Glamorgan coverage.

We also cover nearby Tonypandy (5 miles), Caerphilly (6 miles), Rhondda (6 miles).

Do you need permission in Wales?

In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. 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.

Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.

Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
