In Blackwood, 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
  • Green algae along the bars
  • Leaks at the ridge or eaves

Common causes we find

UV ageing

uPVC components become brittle and crack after years of sun.

Blocked drainage

As with all lanterns, blocked eaves drainage causes overflow.

Covering Blackwood and nearby

Wind-driven rain is the real test of a roof lantern, and the wetter west sees plenty of it. Leaks that appear only in a storm from one direction usually point to the cappings or eaves on that face — a useful clue when you send us photos.

We cover Blackwood as part of Gwent, about 11 miles from Newport, Gwent.

If you're just outside Blackwood, we also cover Risca (6 miles), Caerphilly (6 miles), Pontypridd (7 miles).

Guide prices for uPVC roof lantern repairs in Blackwood

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

Most uPVC roof lantern repairs jobs come in between £175 and £595 ex VAT (£210–£714 including 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 Wales?

In Wales, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010 (as applied in Wales), so we set out the route in writing first. Listed buildings in Wales need listed building consent from the local planning authority for alterations, with Cadw guidance on historic buildings; check with the council before changing a lantern on a listed property.
