Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from Bordon (GU35) and we'll tell you which it is — with the price agreed in writing before any work.

Is it time for glazing bar and capping repairs?
- Gasket rubber poking out, cracked or missing
- Water running down one glazing bar inside
- Rattling or whistling in wind
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.

Even in drier areas, one heavy downpour with blocked eaves is enough to overflow a lantern indoors. Clearing the eaves channel is the simplest prevention there is.

What should you expect to pay in Bordon?

Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. 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 Bordon: questions
Can you repair a lantern someone else installed in Bordon?
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.
Which places near Bordon do you cover?
As well as Bordon, we cover nearby Farnham, Aldershot, Fleet, Godalming and the rest of Hampshire.
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.
