Signs you need uPVC roof lantern repairs

  • Cracked cappings or ridge covers
  • Green algae along the bars
  • Leaks at the ridge or eaves

What usually causes it?

UV ageing

uPVC components become brittle and crack after years of sun.

Blocked drainage

As with all lanterns, blocked eaves drainage causes overflow.

Covering Chelmsford 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.

Close by, we also cover Billericay (8 miles), Witham (9 miles), Maldon (9 miles).

What should you expect to pay in Chelmsford?

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.
