Signs you need glazing bar and capping repairs

  • Gasket rubber poking out, cracked or missing
  • 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.

Fixings working loose

Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.

Covering Darwen and nearby

Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.

Darwen is around 11 miles from Preston, and both are within our Lancashire coverage.

We also cover nearby Blackburn (4 miles), Accrington (6 miles), Chorley (7 miles).

Do you need permission in England?

Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
