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 Monmouth (NP25) 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
- Water at the corners after heavy rain
- Standing water in the eaves channel
Common causes we find
Blocked weep slots
Debris settles at the eaves and blocks the outlets, so the channel fills and overflows inward.
Open corner joints
The eaves beam is mitred or jointed at the corners; if the joint seal fails, water drops straight through.
About Monmouth and the NP25 area
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.
From Newport, Gwent to Monmouth is roughly 20 miles — all part of the Gwent area we cover.
Close by, we also cover Chepstow (12 miles), Abergavenny (13 miles), Pontypool (16 miles).
How much should it cost?
Guide price for eaves beam and gutter repairs: £175–£395 ex VAT (£210–£474 inc 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.
