In South Croydon, as everywhere, when a lantern is letting in a lot of water or the glass is broken, the first job is to stop more damage. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Broken or missing glass
- A capping or vent blown off
- Water near light fittings or sockets
Why it happens
Impact
Falling branches or debris can break glass.
Sudden seal failure
A failing joint can let go in heavy rain.
Covering South Croydon and nearby
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.
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.
We cover South Croydon as part of Greater London, about 10 miles from Westminster.
Close by, we also cover Croydon (1 mile), Purley (2 miles), Wallington (3 miles).
How much should it cost?
Typical range: £195–£395 ex VAT, which is £234–£474 with VAT, per visit. 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.
