We carry out eaves beam and gutter repairs in Penzance and across the TR18 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
- Moss, leaves or grit visible along the base
- Standing water in the eaves channel
What usually causes it?
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 Penzance
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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Penzance is around 24 miles from Truro, and both are within our Cornwall coverage.
We also cover nearby Camborne (12 miles), Redruth (16 miles), Falmouth (21 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 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 Penzance: questions
Do you need to visit to price eaves beam and gutter repairs?
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.
Which places near Penzance do you cover?
As well as Penzance, we cover nearby Camborne, Redruth, Falmouth, Truro and the rest of Cornwall.
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.
