We carry out upstand and kerb repairs in Maghull and across the L31 area. The upstand, or kerb, is the raised frame the lantern sits on.

Signs you need upstand and kerb repairs
- Water appearing below the lantern rather than from the glass
- Soft or spongy timber at the base of the lantern
- Ponding water against the kerb after rain
Why it happens
Kerb too low
If the kerb doesn't rise enough above the finished roof, water sits against the joint during heavy rain.
Membrane not dressed up
The flat roof covering should run up the kerb and be trimmed or flashed. If it stops short, water gets behind it.
About Maghull and the L31 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.
Coastal wind drives rain hard against lanterns, so cappings and ridge seals on the seaward face take the most punishment.
Maghull is around 7 miles from Liverpool, and both are within our Merseyside coverage.
If you're just outside Maghull, we also cover Kirkby (3 miles), Litherland (4 miles), Ormskirk (4 miles).
How much should it cost?
Typical range: £395–£1,295 ex VAT, which is £474–£1,554 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.

Upstand and kerb repairs in Maghull: questions
Can you repair a lantern someone else installed in Maghull?
Yes. We repair lanterns whoever fitted them. If yours is still under the installer's warranty, contact them first so you don't affect it.
Which places near Maghull do you cover?
As well as Maghull, we cover nearby Kirkby, Litherland, Ormskirk, Bootle and the rest of Merseyside.
Can you add insulation to the kerb?
Yes. Insulated kerbs reduce cold bridging and help with condensation around the opening.

If water has soaked the lining it may need making good after the leak is fixed; we can advise, but internal decorating isn't included unless quoted.
