Each glazing bar on a roof lantern has a top capping that clamps the glass onto gaskets. Send photos from March (PE15) and we'll tell you which it is — with the price agreed in writing before any work.

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

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.

Fixings working loose

Screws and clips that hold the capping relax with thermal movement, so the clamp on the glass weakens.

Roof lanterns in March

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.

We cover March as part of Cambridgeshire, about 24 miles from Cambridge.

Guide prices for glazing bar and capping repairs in March

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

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?

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 March: 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 March do you cover?

As well as March, we cover nearby Wisbech, Ely, Peterborough, King's Lynn and the rest of Cambridgeshire.

How much do capping and gasket repairs cost?

Usually £165–£395 ex VAT per lantern depending on how many bars are affected, confirmed in writing before work starts.

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.
