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 from Christchurch (BH23) and we'll tell you which it is — with the price agreed in writing before any work.

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
Why it happens
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 Christchurch
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
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 in Christchurch?
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?
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.

Eaves beam and gutter repairs in Christchurch: questions
Can you repair a lantern someone else installed in Christchurch?
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.
Which places near Christchurch do you cover?
As well as Christchurch, we cover nearby Bournemouth, New Milton, Poole, Totton and the rest of Dorset.
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.
