We carry out eaves beam and gutter repairs in Penarth and across the CF64 area. 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.

What you might be seeing
- Drips along the bottom edge of the lantern
- Water at the corners after heavy rain
- Standing water in the eaves channel
Why it happens
Blocked weep slots
Debris settles at the eaves and blocks the outlets, so the channel fills and overflows inward.
Trees and moss
Lanterns near trees fill with leaves every autumn and need regular clearing.
Roof lanterns in Penarth
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.
Penarth is around 3 miles from Cardiff, and both are within our South Glamorgan coverage.
Close by, we also cover Cardiff (3 miles), Barry (5 miles), Caerphilly (10 miles).
What should you expect to pay in Penarth?
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?
Most lantern repairs in Wales need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 (as applied in Wales) apply and we confirm how the work will be signed off before we start. 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.

Eaves beam and gutter repairs in Penarth: questions
Can you repair a lantern someone else installed in Penarth?
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 Penarth do you cover?
As well as Penarth, we cover nearby Cardiff, Barry, Caerphilly, Cowbridge and the rest of South Glamorgan.
How much does an eaves repair cost?
Clearing and resealing is usually £175–£395 ex VAT; rebuilding a damaged eaves section is priced on survey. You get a fixed price in writing first.
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.
