In Wigston, 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 usually causes it?
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.

Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.

Guide prices for glazing bar and capping repairs in Wigston
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 Wigston: 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 Wigston do you cover?
As well as Wigston, we cover nearby Oadby, Leicester, Market Harborough, Hinckley and the rest of Leicestershire.
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.
