In Purley, as everywhere, many uPVC roof lanterns have an aluminium core with uPVC cladding and cappings. Send photos and we'll tell you what we think has failed.

What you might be seeing

  • Yellowed or brittle end caps
  • Cracked cappings or ridge covers
  • Rattling or whistling in wind

Why it happens

UV ageing

uPVC components become brittle and crack after years of sun.

Blocked drainage

As with all lanterns, blocked eaves drainage causes overflow.

Covering Purley 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.

From Westminster to Purley is roughly 11 miles — all part of the Greater London area we cover.

What should you expect to pay in Purley?

Guide price, per lantern£175–£595 ex VAT£210–£714 inc VAT

Typical range: £175–£595 ex VAT, which is £210–£714 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.

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.

What does a uPVC lantern repair cost?

If the glass is sound and the frame isn't distorted, a repair is usually far cheaper than replacement.
