In Shrewsbury, 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.

Roof lantern glazing bar with the top capping lifted to show the gasket beneath

What you might be seeing

  • A capping visibly higher than its neighbours
  • Rattling or whistling in wind
  • End caps missing at the bottom of a bar

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 Shrewsbury 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.

Close by, we also cover Wellington (10 miles), Telford (13 miles), Oswestry (16 miles).

What should you expect to pay in Shrewsbury?

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

Most glazing bar and capping repairs jobs come in between £165 and £395 ex VAT (£198–£474 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?

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.

Glazing bar and capping repairs in Shrewsbury: questions

Do you cover Shrewsbury?

Yes. We cover Shrewsbury, including the SY1 postcode area, as part of Shropshire. 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.

How do I get a price for glazing bar and capping repairs in Shrewsbury?

Send a few photos of the lantern and the problem, with your Shrewsbury postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.

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.
