What you might be seeing

  • Yellowed or brittle end caps
  • Rattling or whistling in wind
  • Leaks at the ridge or eaves

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 Potters Bar and nearby

Lanterns in central England see a bit of everything — summer sun that ages seals and end caps, autumn leaf fall that blocks eaves, and frosty mornings that bring condensation. A yearly check covers all three.

Potters Bar is around 8 miles from St Albans, and both are within our Hertfordshire coverage.

What should you expect to pay in Potters Bar?

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 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.
