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 Cornwall, 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
- Water at the corners after heavy rain
- Moss, leaves or grit visible along the base
- Standing water in the eaves channel
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 Cornwall
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.
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 Cornwall?
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 England?
In England, 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, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.

Eaves beam and gutter repairs in Cornwall: 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 Cornwall do you cover?
All of Cornwall, including Truro, Redruth, Falmouth, St Austell, Camborne, Newquay. Rural and remote addresses are covered by arrangement.
