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 Llanelli (SA15) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need eaves beam and gutter repairs
- Drips along the bottom edge of the lantern
- Water at the corners after heavy rain
- Staining on the lining just below the eaves
Why it happens
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 Llanelli and the SA15 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

What should you expect to pay in Llanelli?
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.

Eaves beam and gutter repairs in Llanelli: questions

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 you repair a lantern someone else installed in Llanelli?
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.
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.
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.
