The eaves beam is the frame around the base of a lantern, and most designs have a drainage channel inside it that lets water out through small weep slots. Send photos from Brecon (LD3) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for eaves beam and gutter repairs?
- Drips along the bottom edge of the lantern
- Moss, leaves or grit visible along the base
- Standing water in the eaves channel
What usually causes it?
Open corner joints
The eaves beam is mitred or jointed at the corners; if the joint seal fails, water drops straight through.
Trees and moss
Lanterns near trees fill with leaves every autumn and need regular clearing.
Roof lanterns in Brecon
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.

How much should it cost?

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.

Do you cover Brecon?

Do you need to visit to price eaves beam and gutter repairs?
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.
Can I clear the eaves myself?
Only if you can do it safely from a properly secured ladder without standing on the roof or leaning on the glass. If in doubt, don't — falls from flat roofs are a common cause of injury.
Why does my lantern only leak at the corners?
Corners are where the eaves beam is jointed and where water collects. A failed corner seal or blocked weep near the corner is the usual cause.
