In Isleworth, as everywhere, orangery lanterns are larger and often sit within a perimeter roof with internal gutters, so leaks can come from the lantern, the perimeter roof or the junction between them. Send photos and we'll tell you what we think has failed.

What you might be seeing
- Leaks at the lantern edge or around the internal pelmet
- Staining on the orangery ceiling
- Misted units on a large lantern
Why it happens
Internal gutters
Box gutters around the lantern block and overflow inward.
Timber maintenance
Painted timber orangeries need regular redecoration.
About Isleworth and the TW7 area
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.
Across London, many lanterns sit on rear extensions with access only through the house, so we protect floors and plan the work to keep time indoors to a minimum. Parking and any permits are factored into the quote.
We cover Isleworth as part of Greater London, about 9 miles from Westminster.
Close by, we also cover Hounslow (1 mile), Heston (2 miles), Richmond (2 miles).
Guide prices for orangery lantern repairs in Isleworth
Guide price for orangery lantern repairs: £395–£2,495 ex VAT (£474–£2,994 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.
