In Limavady, as everywhere, each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos and we'll tell you what we think has failed.

Is it time for glazing bar and capping repairs?

  • A capping visibly higher than its neighbours
  • Water running down one glazing bar inside
  • Rattling or whistling in wind

Common causes we find

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 Limavady 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.

Limavady is around 15 miles from Derry~Londonderry, and both are within our County Londonderry coverage.

We also cover nearby Coleraine (13 miles), Portstewart (13 miles), Derry~Londonderry (15 miles).

Do you need permission in Northern Ireland?

Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in Northern Ireland. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations (Northern Ireland) 2012; we confirm in writing which route applies before any replacement. Listed buildings in Northern Ireland need listed building consent from the council for alterations; check with the council's planning service before changing a lantern on a listed property.

Glazing bar and capping repairs in Limavady: questions

Do you cover Limavady?

Yes. We cover Limavady, including the BT49 postcode area, as part of County Londonderry. Send photos by WhatsApp or the form for a free guide price, and we'll confirm the fixed price in writing before any work starts.

Can you repair a lantern someone else installed in Limavady?

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.

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.
