In Bletchley, 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.

What you might be seeing

  • Water running down one glazing bar inside
  • 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.

About Bletchley and the MK3 area

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.

We cover Bletchley as part of Buckinghamshire, about 13 miles from Aylesbury.

What should you expect to pay in Bletchley?

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

Guide price for glazing bar and capping repairs: £165–£395 ex VAT (£198–£474 inc 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 Bletchley: questions

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

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

Which places near Bletchley do you cover?

As well as Bletchley, we cover nearby Milton Keynes, Leighton Buzzard, Ampthill, Dunstable and the rest of Buckinghamshire.

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.
