We carry out glazing bar and capping repairs in Houghton-le-Spring and across the DH4 area. Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets.

Signs you need glazing bar and capping repairs
- 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
Fixings working loose
Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.
Damage
Ladders, window cleaning or someone stepping on a lantern can bend a capping or unclip it.
About Houghton-le-Spring and the DH4 area
Freeze-thaw cycles open up tired sealant and gaskets faster than mild weather does. A spring check after a hard winter catches most problems before they leak.
Urban grime and traffic film dull glass and frames quickly; a clean and seal check makes a tired lantern look and perform much better.
We cover Houghton-le-Spring as part of Tyne and Wear, about 11 miles from Newcastle upon Tyne.
Close by, we also cover Chester-le-Street (5 miles), Washington (5 miles), Seaham (5 miles).
Guide prices for glazing bar and capping repairs in Houghton-le-Spring
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 Houghton-le-Spring: questions
Do you need to visit to price glazing bar and capping repairs?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Which places near Houghton-le-Spring do you cover?
As well as Houghton-le-Spring, we cover nearby Chester-le-Street, Washington, Seaham, Sunderland and the rest of Tyne and Wear.
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.
