Is it time for cracked lantern glass replacement?

  • A visible crack in the outer or inner pane
  • A starburst from an impact point
  • A crack running from an edge (often thermal stress)

Why it happens

Thermal stress

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

Spontaneous breakage

Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.

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.

Cracked lantern glass replacement in Barry: questions

Can you repair a lantern someone else installed in Barry?

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.

Which places near Barry do you cover?

As well as Barry, we cover nearby Penarth, Cardiff, Cowbridge, Llantwit Major and the rest of South Glamorgan.

Is it covered by home insurance?

Accidental damage often is; check your policy. We can provide a written quote and photos for your insurer.

Why did my glass crack on a sunny day?

Thermal stress — one part of the pane heats faster than another, often where it's shaded or chipped at the edge.
