In Hazel Grove, 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.

Common causes we find
Gasket shrinkage

Damage
Ladders, window cleaning or someone stepping on a lantern can bend a capping or unclip it.
About Hazel Grove and the SK7 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
In built-up areas, access is often the hardest part of the job — through the house, over a neighbour's roof, or with parking restrictions. We plan access in advance and price any tower or scaffold into the quote.
Hazel Grove is around 8 miles from Manchester, and both are within our Greater Manchester coverage.

Guide prices for glazing bar and capping repairs in Hazel Grove

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.

How do I get a price for glazing bar and capping repairs in Hazel Grove?
Send a few photos of the lantern and the problem, with your Hazel Grove postcode. We'll reply with a guide price and tell you whether a visit is needed before we can fix the price.
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.
