In Thetford, as everywhere, 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 and we'll tell you what we think has failed.

What you might be seeing
- Drips along the bottom edge of the lantern
- Moss, leaves or grit visible along the base
- Staining on the lining just below the eaves
Why it happens
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.
About Thetford and the IP24 area
Sun and UV do more damage than rain on many lanterns here: brittle ridge caps, chalky finishes and hardened gaskets. They're cheap to replace before they let water in.
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.
Thetford is around 27 miles from Norwich, and both are within our Norfolk coverage.

What should you expect to pay in Thetford?
Most eaves beam and gutter repairs jobs come in between £175 and £395 ex VAT (£210–£474 including 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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 Thetford: 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.
Can you repair a lantern someone else installed in Thetford?
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.
