Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from Runcorn (WA7) and we'll tell you which it is — with the price agreed in writing before any work.

Signs you need aluminium roof lantern repairs
- Cappings lifted or rattling
- Misted units
- Corrosion at cut edges or fixings in coastal areas
Common causes we find
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Finish damage
Scratches and chips expose bare metal; coastal air speeds up corrosion.
Covering Runcorn and nearby
Western and upland parts of the UK get more rain and more wind-driven rain than the east, and that's what finds weak cappings and blocked eaves first. Lanterns here benefit from a check of the bars on the most exposed face and a clear eaves channel before winter.
Runcorn is around 12 miles from Chester, and both are within our Cheshire coverage.
We also cover nearby Widnes (1 mile), Halewood (4 miles), Huyton (7 miles).
What should you expect to pay in Runcorn?
Guide price for aluminium roof lantern repairs: £195–£695 ex VAT (£234–£834 inc 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.
