In Didcot, 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

  • Gasket rubber poking out, cracked or missing
  • Water running down one glazing bar inside
  • Rattling or whistling in wind

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.

Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.

What should you expect to pay in Didcot?

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 Didcot: questions

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

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

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.

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.
