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. We carry out eaves beam and gutter repairs across South Glamorgan, with a guide price from your photos and a fixed price in writing before any work starts.

Signs you need eaves beam and gutter repairs

  • Drips along the bottom edge of the lantern
  • Moss, leaves or grit visible along the base
  • Staining on the lining just below the eaves

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 South Glamorgan

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.

Guide price, per lantern£175–£395 ex VAT£210–£474 inc VAT

Most eaves beam and gutter repairs jobs come in between £175 and £395 ex VAT (£210–£474 including VAT), per lantern. 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?

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.
