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 Gwynedd, 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
- Standing water in the eaves channel
- Staining on the lining just below the eaves
What usually causes it?
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.
Roof lanterns in Gwynedd
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
What should you expect to pay for eaves beam and gutter repairs in Gwynedd?
Typical range: £175–£395 ex VAT, which is £210–£474 with 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 Gwynedd: questions
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.
Which towns in Gwynedd do you cover?
All of Gwynedd, including Bangor, Gwynedd, Caernarfon, Dolgellau, Holyhead, Llangefni, Porthmadog. Rural and remote addresses are covered by arrangement.
