In Thamesmead, 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
- Water at the corners after heavy rain
- Standing water in the eaves channel
Common causes we find
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.

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.
London's extensions are often tight to neighbouring walls and roofs. Where a repair needs access over a neighbour's property, we'll tell you in advance so you can arrange it.
From Westminster to Thamesmead is roughly 11 miles — all part of the Greater London area we cover.

What should you expect to pay in Thamesmead?
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.

Eaves beam and gutter repairs in Thamesmead: questions
Can you repair a lantern someone else installed in Thamesmead?
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 Thamesmead do you cover?
As well as Thamesmead, we cover nearby Barking, Welling, Becontree, Dagenham and the rest of Greater London.
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.
