Aluminium lanterns are strong and slim, but they still rely on gaskets, cappings and seals that wear. Send photos from St Albans (AL1) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- Chalky or chipped powder coat
- Misted units
- Corrosion at cut edges or fixings in coastal areas
What usually causes it?
Worn gaskets
Gaskets do the weatherproofing; they harden and shrink with age.
Thermal movement
Aluminium moves with temperature; seals and fixings take the strain.
About St Albans and the AL1 area
Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.
Neighbouring places we cover include Harpenden (5 miles), Hatfield (5 miles), Hemel Hempstead (5 miles).
How much should it cost?
Typical range: £195–£695 ex VAT, which is £234–£834 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.
