We carry out glazing bar and capping repairs in Redruth and across the TR15 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.

What you might be seeing

  • A capping visibly higher than its neighbours
  • Water running down one glazing bar inside
  • End caps missing at the bottom of a bar

Why it happens

Gasket shrinkage

Rubber gaskets shrink back from the ends over time, leaving a gap at the ridge or eaves.

Damage

Ladders, window cleaning or someone stepping on a lantern can bend a capping or unclip it.

Covering Redruth 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.

Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

We cover Redruth as part of Cornwall, about 8 miles from Truro.

Close by, we also cover Camborne (4 miles), Truro (8 miles), Falmouth (9 miles).

What should you expect to pay in Redruth?

Guide price, per lantern£165–£395 ex VAT£198–£474 inc VAT

Typical range: £165–£395 ex VAT, which is £198–£474 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.

Glazing bar and capping repairs in Redruth: questions

Can you repair a lantern someone else installed in Redruth?

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.

Which places near Redruth do you cover?

As well as Redruth, we cover nearby Camborne, Truro, Falmouth, Newquay and the rest of Cornwall.

Can a capping just be clipped back on?

Sometimes, if nothing underneath has failed. We check the gaskets first, because clipping a capping over a perished gasket doesn't stop the leak.

Do you repair uPVC and timber lantern bars too?

Yes. Timber lanterns use different beads and cappings, and we repair those as part of timber lantern repairs.
