We carry out glazing bar and capping repairs in Thatcham and across the RG18 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
- Gasket rubber poking out, cracked or missing
- Water running down one glazing bar inside
- End caps missing at the bottom of a bar
Why it happens
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.

What should you expect to pay in Thatcham?
Most glazing bar and capping repairs jobs come in between £165 and £395 ex VAT (£198–£474 including 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.
