We carry out roof lantern replacement in Northolt and across the UB5 area. We're repair-first, but some lanterns are past it: distorted frames, rot through the main bars, or most of the glass failed.
What you might be seeing
- Several misted or cracked units
- Repeated leaks after previous repairs
- Single-glazed or very poor thermal performance
Common causes we find
Age
Older lanterns can't be brought up to modern performance with repairs alone.
Structural damage
Impact or movement distorts the frame.
Covering Northolt 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.
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 Northolt as part of Greater London, about 11 miles from Westminster.
If you're just outside Northolt, we also cover Greenford (1 mile), Harrow (3 miles), Southall (3 miles).
Guide prices for roof lantern replacement in Northolt
Typical range: £1,995–£4,995 ex VAT, which is £2,394–£5,994 with VAT, supplied and fitted. 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.

Roof lantern replacement in Northolt: questions
Do you cover Northolt?
Yes. We cover Northolt, including the UB5 postcode area, as part of Greater London. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.
Do you need to visit to price roof lantern replacement?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Can the new lantern use the existing opening?
Usually, if the kerb is sound and the size suits a standard or made-to-measure lantern.
Will you tell me if repair is enough?
Yes. We'd rather do a repair that works than sell a lantern you don't need.
