We carry out eaves beam and gutter repairs in Walton-on-Thames and across the KT12 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
- 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.
Trees and moss
Lanterns near trees fill with leaves every autumn and need regular clearing.
Covering Walton-on-Thames and nearby
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.
From Guildford to Walton-on-Thames is roughly 13 miles — all part of the Surrey area we cover.
If you're just outside Walton-on-Thames, we also cover Sunbury-on-Thames (1 mile), Esher (2 miles), Hampton (3 miles).
How much should it cost?
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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.
